Changing the tempo of a song or pattern

There are two ways to change the tempo.

The tempo that you change here will return to the original tempo when you stop play- back and switch to a different pattern or song.

3. Basic operation (Quick Start)

??? Using the Tap Tempo key to change the tempo

While a song or pattern is playing, press the Tap key three times or more at the desired tempo. The ER-1 will detect the interval at which you pressed the Tap key, and will set the tempo accordingly. The tempo can also be changed in this way even if the EA-1 is not currently playing a song or pattern.

Use the cursor [???][???] keys to make the parameter select LEDs indicate Tempo, and the tempo you modified will appear in the display.

Three times or more

1.Turn on the Keyboard function key (the key will light).

2.Use the step keys as a keyboard.

3.You can use the Part Select key to switch the part that you play.

What is a Part?

A Part consists of a synthesizer sound, a phrase pattern (trigger, pitch, gate time), and motion se- quence. Each part is a monophonic synthesizer, and cannot play two or more notes simultaneously (polyphonically). (Refer to p.22 "Pattern mode.")

You are free to modify the sound of each part, and a phrase pattern and motion sequence can be stored independently for each part (refer to p.23 "Editing the sound of a part").

1.Turn on the Keyboard function key, and then press the step keys to play the sound.

2.Press the Part Select key to select the part whose sound you wish to edit.

3.Use the knobs of the Synthesizer section to edit the sound. The Original Value LED will light to indicate the position of the knobs for the original settings of the sound.

taneously.

1.In Song mode or Pattern mode, press the Play/Pause key to begin playback.

2.Press the Part Select key to select the part whose sound you wish to edit.

3.Use the knobs and keys of the Synthesizer section to modify the sound. The sound of the part that is playing will be modified as you move the knobs or keys.

Basic operation (Quick Start)

To save the pattern sounds that you modify here, use the

Write operation (refer to p.17 "Saving a pattern that you create").

If you re-select a pattern or turn off the power without performing the Write operation, the sound will return to its unedited state.

It is not possible to write the sounds you edit in a Song. Only in a Pattern can you

write the edited sounds.

Modifying (editing) a phrase pattern

3.

What is a Phrase Pattern?

A phrase pattern consists of a trigger (note location), pitch, and gate time (note length) at each step. You can modify the phrase pattern for each part by using the sixteen step keys (or by realtime input along with the playback). (Refer to p.22 "Pattern mode.")

Phrase pattern

Please be aware that when you save data, the pattern in the save desti- nation will be overwritten.

1.Edit a pattern as described in "Modifying the sound" or "Modifying (edit- ing) a phrase pattern."

3. Basic operation (Quick Start)

If you want the EA-1 and ER-1 to play the identi- cally-numbered pattern in synchronization, make the following settings.

??? Synchronizing the ER-1 to the EA-1 as master.(Set the EA-1 to "int," and the ER-1 to "Ext.")

???Set the EA-1 and ER-1 to the same MIDI channel (for example, set both to "01").

???On the EA-1 and ER-1, set the MIDI filter setting "P" to "O" (refer to p.42 "MIDI filter settings").

???On the ER-1, set the MIDI note number setting to C-1...A-1 or A#8...G9. (This will prevent the ER-1 from being sounded un- intentionally when note-on messages are received.

It is also easy to make the EA-1 playback in synchronization by connecting it to a se- quencer or synthesizer that can transmit and receive MIDI Clock messages.

4. Pattern mode

In this mode you can play patterns, or edit them to make new patterns.

Press the Pattern mode key to enter Pattern mode.

Playing a pattern

(Pattern Play)

Use the cursor keys to make the parameter select LEDs indicate Pattern. Press the Play/Pause key to start pattern playback. When the pattern finishes playing, it will return to the begin- ning and continue playing.

While listening to a pattern, you can strike the step keys along with the phrase, or move the knobs to modify the sound.

By taking advantage of the various functions of Pattern mode as part of your performance technique, you can enjoy even wider possibilities.

Selecting a pattern

Use the cursor keys to make the parameter select LEDs indicate

Pattern.

Rotate the dial to select one of the 256 patterns: A01...A64, b01...b64, C01...C64, and d01...d64. By holding down the Shift key as you rotate the dial, you can change the pattern number in steps of ten.

The timing at which patterns will

change

When you switch patterns during playback, the change will occur when the currently playing pattern finishes its last step. Until the pattern actually changes, the pattern number selected in the display will blink.

Pattern is changed Begins playing

Setting the playback tempo

??? Using the dial to change the tempo

Use the cursor keys to make the parameter select LEDs indicate Tempo. Rotate the dial to modify the tempo.

??? Using the Tap Tempo key to change the tempo

While the pattern is playing, press the Tap key three times or more at the desired tempo. The EA-1 will calculate the interval at which you pressed the Tap key, and will change the tempo accordingly. You can change the tempo in the same way even when playback is stopped.

When you use the cursor keys to make the parameter select LEDs indicate Tempo, and the tempo you modified will appear in the display.

If you switch to a different pattern without writing the pattern whose tempo you modified, the pattern tempo will return to the previous value. If you wish to keep the modified tempo, you must perform the Write operation (refer to p.33 "Saving a pattern").

Playing from the beginning of a

pattern (Reset & Play)

If you hold down the Shift key when pressing the Play/Pause key, the playback will be forced to playback from the begin- ning. By using this function in conjunction with setting the tempo by the Tap key, you can synchronize the playback with- out using MIDI.

In order to ensure that the phrase always matches, you

will need to perform this adjustment each time.

Pattern A01

Pattern A01

About the tempo when the pattern

is changed

When you switch patterns during playback, the tempo of the previous pattern will always be maintained. If you wish to use the tempo that is stored in the newly selected pattern, press the Stop/Cancel key to stop playback, and then start playback once again. The pattern???s own tempo will be applied from the point at which the pattern was stopped.

You can use the Part Select key to switch the part that will be edited or played using the Keyboard function.

When you select a Part, the LED for that part will light, and you can edit it in the Synthesizer section, or edit a phrase pattern. At this time if the Keyboard function key is off (dark), the step keys will indicate the trigger locations (refer to p.28) of the phrase pattern for that part.

If the Keyboard function key is on (lit) while a pattern is play- ing back, the step keys will light in succession to indicate the pitch that the currently selected part is sounding. If the Key- board function key is off (dark), the step keys will indicate the trigger locations for the phrase pattern of the currently selected part, and the step that is currently playing.

There are two ways to create a pattern. You can start with a pattern that is similar to the desired result and then edit it, or you can create a sound and phrase pattern for each part from scratch. Either way, the EA-1 makes it easy for you to create your own original patterns.

If you wish to save a pattern you create, you must per- form the Write operation before you select a different pattern or turn off the power.

Editing the sound of a part

Select a pattern that is close to what you have in mind (or a pattern which contains no sound or phrase). Use the Part Select key to select the part that you wish to edit. Then operate the knobs and keys to edit the sound. At this time, the Original Value LED will light when the knob etc. that you are currently moving reaches the same value as the original sound of the pattern. Referring to the example sounds in the appendix (p.46) will help you learn how to create your own sounds.

You can also edit while playing back a pattern. It is also pos- sible to use an external MIDI device to control the value of each knob (refer to p.43 "About MIDI").

If the sound does not change when you rotate a knob or switch the setting of a key, either another knob or key has been set so that the parameter you are attempt- ing to adjust has no effect, or the Motion Sequence func- tion (p.29 "Motion Sequence") is operating.

Synthesizer parameters

OSCILLATOR

This specifies the basic waveform and pitch of the sound.

This parameter creates a smooth change in pitch from one note to the next. As this knob is turned further toward the right, the pitch will change more slowly.

If portamento is raised excessively, a certain amount of time will elapse before the destination pitch is reached.

OSC Balance (oscillator balance)

OSC1...OSC2

Adjust the volume balance between the two oscillators. Ro- tating the knob all the way to one side will cause the level of the other oscillator to be 0. If you wish to hear the result of OSC Mod, set this knob in the OSC2 position.

4.Pattern mode

OSC2 Pitch Ofs (OSC2 pitch offset)

???1 octave ... 4 octaves

Specify the pitch of OSC2 relative to the pitch of OSC1. The pitch of OSC2 can be adjusted in the range of ???1 octave to 4 octaves from the pitch of OSC1.

The pitch of OSC1 will be the pitch that sounds when you use the keyboard function or the pitch specified for a phrase pattern.

Specify the basic waveform of OSC1.

(sawtooth wave)

This waveform is rich in overtones, and is suitable for bass or synth lead sounds.

(square wave)

This waveform contains only the odd-numbered har monics, and produces a tone typical of electronically produced sound.

(triangle wave)

This waveform is more mellow than the sawtooth wave or square wave, and is suitable for sub-bass sounds etc.

Audio In

The audio signal input from the audio input jack will be used as OSC1.

So that they will be particularly suitable for bass sounds, the waveforms of OSC1 have a slightly heavier sound (fun- damental) than the waveforms of OSC2.

Specify the basic waveform of OSC2 (refer to OSC1 Wave).

When OSC Mod is set to Deci, the basic waveform

selection will have no effect.

OSC Mod (oscillator modulation)

off, Ring, Sync, Deci

Select the type of modulation that will occur between the oscillators. Since OSC2 will be modulated (i.e., it will be the slave), the results of the modulation will be output from

OSC2.

For either of the types of oscillator modulation, using a motion sequence etc. to change the pitch of OSC2 will pro- duce timbral changes.

??? Off (When the OSC Mod LED is dark)

When OSC Mod is off, the oscillators will not modulate each other.

By using OSC2 Pitch Ofs to create a slight difference in pitch between the oscillators, you can produce a spacious detune effect. Setting a one-octave difference in pitch is effective when you wish to create thick synth-bass sounds etc.

??? Ring Modulation

This type of modulation generates a frequency consisting of the sum and difference of the OSC1 and OSC2 frequen- cies. When you move the OSC2 pitch offset knob the tim- bre will change, producing metallic sounds or sound effects. The modulated sound will be output from OSC2

The tone and volume of Ring Modulation may vary

depending on the phase difference between OSC1 and OSC2.

??? Oscillator Sync

This type of modulation forcibly resets the OSC2 waveform by synchronizing its pitch to the pitch of OSC1. Moving the pitch of OSC2 will produce the popular "sync lead" sound. The modulated sound will be output from OSC2. Differences in the OSC1 waveform will not affect the out- put of OSC2.

??? Decimator

This type of modulation reproduces the OSC1 waveform at the sampling frequency of OSC2. The digitized OSC1 waveform will be output from OSC2. This is effective when creating electric bass sounds etc.

If OSC1 is a square wave, Decimator will have little effect.

When OSC Mod is set to Decimator, the basic wave-

form of OSC2 will be ignored.

Filter

The filter processes the sound produced by the oscillator to make it less bright, etc.

Trigger on

Set the cutoff frequency of the low-pass filter. Overtones higher than the cutoff frequency will be cut, making the sound more mellow.

If Cutoff and EG Int are set to 0, you will hear virtu- ally no sound.

This parameter adds character to the sound by boosting the region around the cutoff frequency. If you raise the reso- nance and turn the Cutoff knob (or adjust EG Int and De- cay), you will hear the typical "meow-ing" sound typical of analog synthesizers.

If the resonance is raised, the sound may be distorted de- pending on the cutoff frequency or on the pitch that you play.

Specify the depth and direction of the effect that the EG (envelope generator) will have on the cutoff frequency. The EG will start when trigger-on occurs (the instant you play the keyboard). If this knob is in the center position, the EG will have no effect.

If the gate time length of a step extends beyond the point at which the next step is sounded, the EG will not be re-triggered for the next step.

Specify the time over which the EG will decay. In conjunc- tion with the Cutoff and EG Int parameters, this controls the way in which the sound will change over time. If EG Int is set to a negative (???) setting, Decay Time can be used in place of Attack Time.

AMP

These parameters adjust the volume level and distortion effect.

Set the delay time. Rotating the knob toward the right will lengthen the delay time.

If you have selected Tempo Delay as the effect type, this parameter will let you set the tempo in terms of sixteen dif- ferent multiples of the step: 1/4, 1/3, 1/2, 2/3, 3/4, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 7, or 8.

Depending on the tempo setting, it may be impos- sible to set the delay time. In such cases, set the delay time to half the desired value.

Chorus/Flanger settings

Set the Type Select button to Chorus/Flanger, and adjust the chorus/flanger. Chorus creates minute differences in the pitch to produce an ensemble effect, and Flanger adds a "swooshing" modulation to the sound.

Adjust the depth of the chorus/flanger effect. Rotating the knob toward the right will change from a chorus effect to a flanger effect.

Raising the depth excessively may cause the sound to distort.

Adjust the LFO speed of the chorus/flanger. Rotating the knob toward the right will speed up the LFO.

Turn distortion on/off. Distortion is an effect that intention- ally distorts the sound to produce a hard sound even from a mellow waveform. It is highly effective to raise the reso- nance and use distortion.

Adjust the volume.

Effect

Here you can apply effects to the sound.

The Depth and Time knobs will edit the effect that is se-

lected by Type Select.

Tempo Delay settings

Set the Type Select button to Tempo Delay, and adjust the delay. Delay is an effect that plays back a time-delayed ver- sion of the original signal, and is also known as "echo." Tempo Delay is a delay that can automatically synchronize the delay time to the tempo of a pattern. If the MIDI Clock parameter is set to "Ext" (external), the delay time can also be synchronized to the clock of an external device. (Refer to p.39 "Synchronizing the EA-1 and an external MIDI device.")

Adjust the depth of the delay and the amount of feedback (the number of delay repeats). Rotating the knob toward the right will increase the level of the delayed sound and the amount of feedback.

Raising the Depth excessively may cause the sound

to distort.

4.Pattern

Length, Scale/Beat settings

You can set the length (the length of the entire pattern) and the basic beat (time signature).The Length and Scale/Beat you specify here will affect the correspondence between step keys and note values, and the maximum number of steps as shown in the following diagram.

While you hold down the Shift key, the step keys will light to indicate the length and beat of the current pattern.

To change the Length, hold down the Shift key and press a Step Key 1...4.

To change the Beat/Scale, hold down the Shift key and press a Step Key 5...7.

It is not possible to view or change the Length or Beat/ Scale during playback or recording, or during Pattern Set Play.

??If you select triplets (
3 x 12) for Beat/Scale, step keys 13...16 will have no function.

Shift + step key 6 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

What is Length?

In this context, "Length" refers to the length of the rhythm pat- tern.

The "Length" of the pattern will be either 16 steps or 12 steps, depending on the Scale and Beat settings of the pattern. A rhythm pattern in triple meter will be shown in triplets. De- pending on the Length and Beat settings, a single pattern can have up to 64 steps.

Swing settings

By adjusting the Swing settings you can offset the note timing of the steps. For example, you can change a straight 16-beat by adding a slight "bounce" or shuffle. The Swing value can be adjusted from 50 to 75 (%), and will affect the note timing of even-numbered steps. A setting of 50 will produce a perfect 16- beat, and a setting of 66 will produce a shuffle.

1.If a pattern is playing back, press the Stop/Cancel key to stop playback.

2.Rotate the dial to select the pattern for which you wish to make Swing settings.

3.Hold down the Shift key, and press step key 8 (Swing). Key 8 will light.

4.A value will blink in the display. Rotate the dial to set the Swing value.

5.Once again press step key 8 to execute the Swing setting (key 8 will go dark).

If you decide to cancel without making the setting, press the Stop/Cancel key.

If the Length and Beat/Scale settings are set to triplets (
3 x 12), the Swing setting has no effect.

It is not possible to view or adjust the Swing parameter during playback or recording, or during Pattern Set Play.

Creating a phrase pattern

There are three ways to create a phrase pattern.

Realtime recording

Use the Keyboard function to play the step keys at the exact timing you wish to record them.

Step recording

Use the Keyboard function to specify the pitch of the note for each target step to create the phrase.

Example display

Step 10

Length 1

Step 5(37)

Length 3

Event editing

Edit the data (trigger, pitch, gate time) for each step to create the phrase.

If you wish to erase the phrase of each part before you create your own rhythm data, refer to p.29 "Erasing phrase data from a part."

Realtime recording

Please refer to "Realtime recording (Using the Keyboard func- tion to create a phrase)" (p.16) in chapter 3. Basic operation (Quick Start).

Step recording

Please refer to "Step recording (Using the step keys to create a phrase)" (p.16) in chapter 3. Basic operation (Quick Start).

About the Target Step

The value shown in the display when the parameter select LEDs indicate Step Rec is called the "target step." The value shown in the display indicates the location of a certain step in the phrase pattern. To change the target step, you can use the dial or press one of the sixteen step keys. Alternatively, you can hold down the Shift key and use the Select keys to move forward or back- ward in single steps.

The maximum number of steps will depend on the length

and scale/beat settings.

In the case of a pattern with a length of 2 or greater, you can use the Select keys to move the select LED in the lower line (red) in order to change the length that is shown by the step keys, and verify or modify the trigger locations.

When the Keyboard function key is on, the step keys will not indicate the target step. When the Keyboard function is off, the step key corresponding to the target step will blink.

Event editing

A phrase pattern consists of the following three data items for each step. For each step, you can set these three items.

???Trigger: Whether or not a note will sound

???Pitch: The pitch that will be sounded

???Gate time: The duration of the sound

Changing the trigger settings

1.Turn off the Keyboard function key (the key will be dark).

2.Use the cursor keys to make the parameter select LEDs indi- cate either Pattern, Tempo, or Step Rec.

3.Use the Part Select key to select the part that you wish to edit.

4.For a pattern with a pattern length of 2 or more, you can use the Select keys to move the red select LEDs to left or right to change the length location that you will edit.

5.The step keys will light to indicate the trigger locations of the pattern for that part. You can press each key to switch the trigger on/off for that step. Each time you press a step key, the trigger will alternate on (lit) and off (dark).

Changing the pitch

1.Turn off the Keyboard function key (the key will go dark).

2.Use the cursor keys to make the parameter select LEDs indi- cate Pitch.

3.Use the Part select key to select the part that you wish to edit.

4.The step keys will light to indicate the trigger locations of the pattern for that part. Press the step key for the step whose pitch you wish to edit (the key will blink). By pressing a step key where a trigger exists, you can audition its pitch.

5.Rotate the dial to modify the pitch of that step.

When the display is showing the Pitch, pressing a step key will not switch its trigger on/off.

Changing the pitch of a step whose trigger is off will have no effect. If you turn that trigger on, the specified pitch will be used. If you wish to transpose the pitch for one part of the en- tire pattern, refer to p.30 "Changing the pitch data of a part (Pitch Shift)."

The pitch will be shown in the display as follows.

Changing the gate time

1.Turn off the Keyboard function key (the key will go dark).

2.Use the cursor keys to make the parameter select LEDs indi- cate Gate Time.

3.Use the Part select key to select the part that you wish to edit.

4.The step keys will light to indicate the trigger locations of the pattern for that part. Press the step key for the step whose gate time you wish to edit (the key will blink). By pressing a step key where a trigger exists, you can audition its pitch.

5.Rotate the dial to modify the gate time of that step.

The value shown in the display is the gate time length in units of a step. For example if the gate time is set to 1.0, the gate time will be exactly as long as one step.

If the gate time length extends into the timing of the next note, the filter EG of the next note will not be retriggered.

When the display is showing the Gate Time, pressing a step key will not switch its trigger on/off.

Changing the gate time of a step whose trigger is off will have no effect. If you turn that trigger on, the specified gate time will be used.

If you wish to save the pattern you edit using these func- tions, you must perform the Write operation before se- lecting a different pattern or turning off the power.

Erasing phrase pattern data from

a part

To erase the phrase pattern data for the selected part, you can use one of the following two methods in addition to turning each of the sixteen step keys off.

Erasing data during playback or

recording (Erase)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Playback the motion sequence with Trig Hold setting

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

There will be no effect when the Motion Sequence LED is dark (off).

Recording a motion sequence

You can record knob movements (motion sequence) for each part. When recording a motion sequence, only one knob is valid for each part. If you record a motion sequence on the same part using a different knob, the effect of the previously recorded knob will disappear.

For the recording procedure, refer to p.18 "Using a motion se- quence" in section 3. Basic operation (Quick Start).

Motion sequences are recorded in realtime while you listen to the playback. It is not possible to partially modify a motion sequence after it has been recorded. You will need to keep trying until you record a motion sequence to your liking. (Refer to p.31 "Erasing motion sequence data from a part.")

Checking motion sequence data

Hold down the Shift key and press the Motion Sequence key. If motion sequence data has been recorded in the selected part, step keys 1, 2, 3, 4 will light.

It is not possible to check for motion sequence data

during playback, recording, or Pattern Set Play.

Performing this operation will not affect the pitch and

gate time data.

Erasing all data from a part (Clear Part)

This operation erases all phrase pattern and motion sequence data at once.

1.If the pattern is playing, press the Stop/Cancel key to stop playback.

2.Press the Part key to select the part whose data you wish to erase.

3.Hold down the Shift key and press step key 12 (Clear Part). (Key 12 will blink.)

4.Once again press step key 12 to clear the data.

To cancel without clearing the data, press the Stop/Cancel key.

When you perform this operation, the pitch of all steps will be set to "C4," and the gate time to "1.00."

Transposing a phrase (Transpose)

This operation lets you transpose a phrase.

1.While you continue pressing the Transpose key, the display will indicate the current transposition status.

2.While holding down the Transpose key, rotate the dial to trans- pose the phrase in semitone steps. +/???1 transposes the pitch by a semitone, +/???2 by a whole tone, +/???7 by a fifth, and +/??? 12 by one octave.

While holding down the Transpose key you can also use the step keys or Select keys to transpose.

When you hold down the Transpose key and use the step keys to specify the transposition, step key 4 will correspond to the C pitch.

To transpose an individual part, use the Pitch Shift op- eration described below.

When you transpose the pitch, the Transpose key will light. If the value is set to 0, the key will go dark.

The Transpose value is not saved. The next time that the power is turned on, the value will be 0.

Moving data within a part

(Move Data)

The Move Data operation lets you move the phrase pattern and motion sequence data of a part backward or forward, or to shift the pitch of an entire part.

Use this when you want to change the starting location of a pattern.

1.If the pattern is playing, press the Stop/Cancel key to stop playback.

2.Hold down the Shift key and press step key 9 (Move Data). (Key 9 will blink.)

3.Turn off the Transpose key (the LED will go dark).

4.Use the Part select key to select the part whose data you wish to move. If you wish to select both parts 1 and 2, press the key several times to make both LEDs blink.

5.A number will blink in the display. Rotate the dial to select the number of steps and the direction (positive or negative) in which the data will be moved.

6.Press the blinking step key 9 to execute the Move Data opera- tion.

To cancel without executing, press the Stop/Cancel key.

The Move Data operation applied to all steps of the selected part. Data that is moved beyond the last step of the pattern will "wrap around" to the first step. For example if 64-step data is moved for "5" steps, the data that was in steps 60 through 64 will be moved to steps 1 through 5. Likewise, data that is moved earlier than the first step of the pattern will "wrap around"to the last step. For example if 48-step data is moved for "???3 " steps, the data that was in steps 1 through 3 will be moved to steps 46 through 48.

With a setting of 3

The data of each step will be moved three steps toward

With a setting of ???2

The data of each step will be moved two steps toward

Use this when you want to shift the pitch data of all steps in a part.

1.If the pattern is playing, press the Stop/Cancel key to stop playback.

2.Hold down the Shift key and press step key 9 (Move Data). (Key 9 will blink.)

3.Turn on the Transpose key (the LED will blink).

4.Use the Part select key to select the part whose pitch you wish to shift. If you wish to select both parts 1 and 2, press the key several times to make both LEDs blink.

5.A number will blink in the display. Rotate the dial to select the amount of pitch shift. +/???1 transposes the pitch by a semitone, +/???2 by a whole tone, +/???7 by a fifth, and +/???12 by one octave.

6.Press the blinking step key 9 to execute the Move Data opera- tion.

To cancel without executing, press the Stop/Cancel key.

6.Press step key 10 once again to execute the Copy Part opera- tion.

To cancel, press the Stop/Cancel key.

For details on data copy within the same part, refer to the following section "Data Copy within a part."

Data Copy within a pattern

Phrase pattern data (including motion sequence data) that you create for a pattern of length 1 can be copied to the steps of lengths 2...4. This function is a convenient way to create a pat- tern that uses similar phrases repeatedly.

1.Create a pattern with a length of 1, and Write it into memory. (Refer to p.32 "Saving a pattern.")

2.At this point, the same data as in length 1 will automatically be copied to the steps of lengths 2...4.

3.Change the pattern length to the desired length. (Refer to p.26, "Length, Scale/Beat settings.")

4.The steps of lengths 2...4 will contain the same data as length

1.Now you can edit the data of lengths 2...4 to complete the pattern.

The data will be copied in a similar way when the pattern length is 2 or 3 (refer to the table below). If you shorten a pattern you create, the data will be copied according to the shortened length.

Copy Pattern data

The data that is copied automatically when you Write a pattern does not force the pattern length (1--4) to change. If the length is 4, data will not be copied within the pattern.

5.Song mode

Recording knob movements or your

performance in a song

(Event Recording)

In addition to placing patterns in a desired playback order, Song mode also lets you record your realtime performance on the step keys using the Keyboard function, and knob movements you perform.

Recording this type of performance in Song mode is referred to as "event recording."

Event recording lets you record the following three types of per- formance data (event data).

???Your performance using the Keyboard function

???Your performance using the knobs and switches (only for the selected part)

???Tempo

Event recording allows you to record two or more types of events in the same area, as long as the events are played at the same time.

Event recording always rewrites the previous data ("replace recording"), and when you record your performance, any event recording data previously in that area will be erased. (It is not possible to layer event recording over the same area.)

1.Select the song on which you wish to record events.

2.Use the cursor keys to make the parameter select LEDs indi- cate Position.

3.Use the dial or the Select keys to move to the position at which you wish to begin recording.

4.Press the Rec key, and then press the Play/Pause key to begin event recording.

5.Use the part keys and/or the knobs to perform.

6.Press the Stop/Cancel key to stop event recording.

If the musical data of the song coincides with the event-recorded data, the song data will be given priority during playback.

Knob movements that are event-recorded in Song mode will always playback in a way that corresponds to the Smooth type motion sequence setting (and not the Trig Hold type).

If you wish to save the event recording, you must per- form the Write operation. If you switch songs or turn off the power without performing the Write operation, the data that was recorded will be lost.

If during playback you operate a knob that had been event-recorded, playback of the events of that knob will be cancelled until it reaches the next position. However if you modify the tempo that was event-recorded, the tempo will be cancelled until the end of the song.

After rewinding a song, it may not be possible to play- back exactly according to the event data.

Synchronizing the EA-1

with external MIDI devices

(MIDI Clock)

The Global mode Clock setting allows the tempo of the EA-1 to be synchronized with the tempo of an external MIDI device that is able to send or receive MIDI Clock messages.

For details on synchronization settings of your external MIDI device, refer to the owner's manual for your device.

Even if you set Clock to Ext, the EA-1 will operate with its own internal clock if no MIDI Clock messages are being received at its MIDI IN connector.

Synchronizing the EA-1 to a

master external MIDI device (Ext)

1.Use a MIDI cable to connect the MIDI IN connector of the EA-1 to the MIDI OUT connector of the external MIDI device (sequencer or synthesizer etc.).

2.Use the cursor keys to make the parameter select LEDs indi- cate Clock.

3.Rotate the dial to select "Ext" (external clock).

4.Make settings on the external MIDI device (master) so that it will transmit MIDI Clock messages.

5.Return to Pattern mode or Song mode.

6.When you start the sequencer of the external MIDI device, the EA-1 will simultaneously begin playback.

7.If MIDI Clock data is being received at the MIDI IN connec- tor, you can make the EA-1 playback in synchronization with the external MIDI device by pressing the EA-1's Play/Pause key.

Adjusting the volume of

If the MIDI Clock parameter is set to "Ext" and the EA-

6.Global mode

the Audio In

These parameters adjust the volume that is input to the Audio In jacks. For the procedure, refer to p.19 "Connecting various sources to the audio inputs" in section 3. Basic Operation (Quick Start).

If a MIDI Start message is received while the EA-1 is already playing in synchronization with MIDI Clock, the EA-1 will begin playback from the beginning of the cur- rently playing pattern (or in the case of a song, from the beginning of the pattern that was playing when the Start message was received).

Synchronizing an external MIDI

device to the EA-1 as master (int)

1.Use a MIDI cable to connect the MIDI OUT connector of the EA-1 to the MIDI IN connector of the external MIDI device (sequencer or synthesizer etc.).

2.Use the cursor keys to make the parameter select LEDs indi- cate Clock.

3.Rotate the dial to select "Int" (internal clock).

4.Make settings on the external MIDI device (slave) so that it will receive MIDI Clock messages.

5.When you start playback on the EA-1, the external MIDI de- vice will begin playback in synchronization.

When you perform the Reset & Play operation to begin playback from the beginning of the pattern, the EA-1 will transmit only a MIDI Start message.

Protect settings

(Memory Protect)

This is the memory protect setting for Pattern mode and Song mode. When protect is "on," the Write key will not function, and it will not be possible to rewrite data or to receive MIDI data dumps.

If you wish to save data you edited or to receive a data dump, you must turn protect "oFF."

1.Press the Stop/Cancel key to stop playback.

2.Use the cursor keys to make the parameter select LEDs indi- cate Protect.

3.Rotate the dial to turn Protect "on" or "oFF."

If you wish to save the Protect setting, perform the Global mode Write operation.

This setting applies to Pattern mode and Song mode. In Global mode and MIDI mode, it is always possible to

Write data regardless of the Protect setting.

With the factory settings, this will be "on."

Saving the settings you

modify in Global mode

(Write)

When you perform the Write operation in either Global mode or MIDI mode, the modified settings of both modes will be saved.

Here's how to save the Global mode settings. If you wish to save the settings you modify, you must perform this Write op- eration. Each time you turn on the power, those settings will be in effect. Conversely, if you do not wish to save the modified settings, simply turn off the power without performing the Write operation.

1.Press the Stop/Cancel key to stop playback.

2.Press the Global mode (or MIDI mode) key.

3.Press the Write key once (the key will blink). The display will indicate "---."

4.Press the Write key once again to write the data.

To cancel, press the Stop/Cancel key.

In Global mode or MIDI mode, it is always possible to execute the Write operation, regardless of the Protect settings (see the previous section).

part 2 (P2 ch)

This sets the MIDI channel of part 2. The same MIDI channel is used for both transmission and reception. With the factory set- tings this will be "2."

1.Use the cursor keys to make the parameter select LEDs indi- cate P2 ch.

2.Rotate the dial to select the channel.

If part 1 and part 2 are set to the same channel, the sounds of part 1 and part 2 will be heard simultaneously when controlled from an external MIDI device.

Reception

Here's how EA-1 system exclusive data can be received from an external MIDI data filer or computer connected to the MIDI IN connector.

1.Connect the MIDI IN connector of the EA-1 to the MIDI OUT connector of the external MIDI device that will transmit the MIDI data dump (another EA-1, or a computer that is run- ning a MIDI data filer program or editing program, etc.).

2.Set the MIDI channel of the external MIDI device and the EA-1 to match. However when transmitting from a data filer, it is not normally necessary to match the MIDI channel.

3.Use the cursor keys to make the parameter select LEDs indi- cate Dump.

4.Transmit the data dump from the external MIDI device.

Details on data dumps are provided in the MIDI implementa- tion chart of the EA-1.

Consult your local Korg distributor for more information on MIDI implementation

Do not touch the keys of the EA-1 while a data dump is in progress.

When the parameter select LEDs indicate Dump, sys- tem exclusive data can be transmitted or received even if the MIDI Filter parameter "E" is set to "-."

If the MIDI Filter parameter "E" is set to "O," system exclusive data can be transmitted or received in any mode.

7.MIDI mode

MIDI filter settings

Here you can select the types of MIDI message that will be trans- mitted and received.

For each character "PCE" in the display, select "O" if you want that type of message to be transmitted and received, or select "- " if you do not want that type of message to be transmitted or received.

1.Use the cursor keys to make the parameter select LEDs indi- cate MIDI Filter.

2.Rotate the dial to select the combination of message types that will be transmitted and received; "O" allows transmis- sion and reception, and "-" disables it.

P: Transmission/reception of Program Change, Bank Select, and Song Select messages.

C: Transmission/reception of Control Change messages.

E: Transmission/reception of Exclusive data. However when the parameter select LEDs indicate Dump, Exclu sive data can be transmitted/received regardless of this setting.

Saving the settings you

modify in MIDI mode (Write)

When you perform the Write operation in either MIDI mode or Global mode, the modified settings of both modes will be saved.

Here's how to save the MIDI mode settings. If you wish to save the settings you modify, you must perform this Write opera- tion. Each time you turn on the power, those settings will be in effect. Conversely, if you do not wish to save the modified set- tings, simply turn off the power without performing the Write operation.

1.Press the Stop/Cancel key to stop playback.

2.Press the MIDI mode (or Global mode) key.

3.Press the Write key once (the key will blink). The display will indicate "---."

4.Press the Write key once again to write the data.

To cancel, press the Stop/Cancel key.

In Global mode or MIDI mode, it is always possible to execute the Write operation, regardless of the Protect settings (see the previous section).

Never turn off the power while data is being written to memory. This may damage the data.

About MIDI

1. MIDI channels

bytes of the parameter no.) to select the parameter. Then trans- mit Data Entry (MSB) [Bn, 06, mm] and Data Entry (LSB) [Bn, 26, vv] (control change #06 and 38) (mm, vv: upper and lower bytes of the value, together expressing 16,384 steps) to set the value. The EA-1 uses only the MSB value (128 steps) of the Data Entry message.

6. If "stuck notes" occur

2. Note-on/off

When you use the Keyboard function and press a step key, the note number assigned to that step key will be transmitted as a Note-on message [9n, kk, vv] (n: channel, kk: note number, vv: velocity) on the MIDI channel specified for that part. On the EA-1, the vv: velocity value is fixed at 64H (100). When you release the step key, a note-off message [8n, kk, vv] is transmit- ted. However, most devices do not transmit note-off velocity, and neither does the EA-1. When note-on/off messages are re- ceived on the MIDI channel assigned to a part, that part will sound.

Note-on/off messages are transmitted and received on the MIDI channels that you specify for part 1 and part 2 in MIDI mode.

3. Switching patterns

When you switch patterns, Program Change and Bank Select messages [Bn, 00, mm] (control change #00), [Bn, 20, bb] (con- trol change #32) (mm: bank number upper byte, bb: bank num- ber lower byte, together allowing 16,384 banks to be selected) will be transmitted.

If a Program Change is received on the MIDI channel of the EA-1, patterns will be switched within the same group (e.g., from A01 to A02). After a Bank Select has been received, the next-received Program Change will be able to switch to a pat- tern of a different group (e.g., from A01 to C01).

Transmission and reception of Program Change messages can be controlled by the MIDI mode MIDI Filter setting.

4 Applying pitch bend

Pitch bend messages [En, vv, vv] (vv, vv: lower and upper bytes of the value, together expressing 16,384 steps, where 8192 (vv, vv = 00H, 40H) is the center value) are not transmitted, but can be received to apply a pitch bend effect. The range of pitch bend- ing is specified by the Pitch Bend Range setting of MIDI mode.

5. Using NRPN messages to edit

NPRN (Non Registered Parameter No.) messages are messages to which manufacturers are free to assign their own functions. On the EA-1, NRPN messages are assigned to all knobs and keys of the Synthesizer section other than Motion Seq.

To edit, first use NRPN (LSB) [Bn, 62, rr] and NRPN (MSB) [Bn, 63, mm] (control change #98 and 99) (rr, mm: lower and upper

7. About synchronization

Two or more sequencers can be connected via MIDI and made to playback in synchronization. Messages used for synchroni- zation (realtime messages) include Timing Clock [F8], Start [FA], Continue [FB], and Stop [FC].

In a synchronized system, one synthesizer (the master) will transmit these messages, and the other sequencer(s) (the slave(s)) will receive these messages. The slave devices will playback according to the tempo specified by the Timing Clock messages transmitted by the master. Twenty-four Timing Clock messages are transmitted for each quarter note. When the EA-1???s Global mode parameter Clock is set to INT, it will be the master de- vice, and will transmit these realtime messages. When Clock is set to EXT, it will be the slave device, and will receive these realtime messages. However even when Clock is set to EXT, the EA-1 will operate according to its own internal clock if no Tim- ing Clock messages are being received. The Start message speci- fies when playback will begin. When the Start/Pause key is pressed on the master device, it will transmit a Start message. Slave devices that receive this Start message will synchronize to the Timing Clock messages subsequently received, and will begin playback from the beginning. If the Start/Pause key is pressed on the master devices when it is paused, the master will transmit a Continue message. When a slave device receives the Continue message, it will resume playback from the point where it is currently stopped. If the Stop key is pressed during playback, the master will transmit a Stop message. Slave de- vices will stop playback when they receive a Stop message.

8. Synchronization in Song mode

In Song mode, the EA-1 can transmit and receive Song Select and Song Position Pointer messages. When you switch songs, a Song Select [F3 ss] message will be transmitted (ss: song num- ber, where one of 128 songs can be selected. On the EA-1 you can select 16 songs.) If the EA-1 receives a Song Select message in Song mode, it will switch songs. Transmission and reception of Song Select messages can be restricted by the MIDI Filter settings of MIDI mode. If you change the current position on the master device (i.e., the device whose Clock is set to INT) when the song is stopped, a Song Position Pointer message [F2 pp pp] will be transmitted. (pp: the number of MIDI beats from the beginning of the song; i.e., the number of Timing Clocks divided by six.) Song Position Pointer indicates the location at which the sequencer is currently stopped. When Song Position Pointer is received in Song mode by a slave device (i.e., a de- vice whose Clock is set to EXT), it will change the location at which its song is currently stopped to match the location of the master. However on the EA-1, the length of each pattern may be different, so the master and slave will not necessarily be in

the same location. When the Start/Pause key is pressed on the master device, a Continue message is transmitted, and the song will begin playback from the currently selected position. When the slave device receives the Continue message, it will synchro- nize to the Timing Clock messages and begin playback from the current point in the song. In the same way as synchronizing the playback from the beginning of the song, you can specify the location at which playback will start, and then playback in synchronization. If you use the dial or Select keys to fast-for- ward or rewind while the song is playing, Song Position Pointer messages will not be transmitted. Be aware that if you perform these operations during synchronized playback, the synchro- nization will be lost. Also, even if Song Position Pointer mes- sages are received during playback, the playback location will not change.

Troubleshooting

Power switch!

???Is the AC adapter connected?

???Is the AC adapter plugged into an AC outlet?

No sound!

???Is your amp, mixer, or headphones connected to the correct jack? (Can you playback a pattern? If so, the connections are correct.)

???Are your amp or mixer powered-on and set correctly?

???Is the master volume knob of the EA-1 raised?

9. About system exclusive messages

Manufacturers are free to use system exclusive messages in any way they choose, and these messages are used mainly to trans- mit and receive parameters that are specific to particular de- vices, such as sound data and editing data.

The system exclusive message format of the EA-1 is [F0, 42, 3n, 51, ... F7] (n: exclusive channel).

However, some system exclusive messages have been defined for use in a specific way, and these are called "universal system exclusive messages."

Of the several different universal system exclusive messages, the EA-1 supports the following one.

- When an Inquiry Message Request [F0, 7E, nn, 06, 01, F7] is received, the EA-1 will transmit an Inquiry Message [F0, 7E, nn, 06, 02, (nine bytes), F7] that means "I am a Korg EA-1 and my system version is ..."

10. Transmitting sound setting

data (Data Dump)

Song, Pattern, or All (song, pattern, global) data can be trans- mitted as MIDI exclusive data, and stored on an external de- vice. This data is transmitted by the MIDI mode Dump com- mand. The channel used for transmission and reception of this data is set by the MIDI mode MIDI ch setting. Data dumps are also transmitted when a Data Dump Request message is re- ceived.

11. Editing sounds etc.

By sending MIDI exclusive data dumps, you can rewrite all patterns or individual programs. By using NRPN messages in Pattern mode, you can edit the knobs that are active for each part.

Restoring the factory set

data

The pattern and song data with which the EA-1 is shipped from the factory is referred to as the "preloaded data," and you can restore this preloaded data back into the memory of the EA-1. When you do this, the patterns you created and the songs which use these patterns will be erased, and replaced by the preloaded data. If you wish to keep the patterns and songs you created, you must save the data on a data filer etc. before you load the preloaded data.

1.While simultaneously pressing the Transpose key and the Write key, turn on the power.

2.The display will indicate "PLd," and the Play/Pause key will blink.

3.To load the factory preloaded data, press the blinking Play/ Pause key.

This will require apporoximately 15 seconds.

To cancel, press the Stop/Cancel key.

When loading is complete, the EA-1 will return to its initial state. After several seconds the display will indicate pattern number "A01," and the EA-1 will be in Pattern mode.

Never turn off the power during the Load process. The data may be damaged.
