Selecting a pattern

Creating a pattern

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-1makes 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.

Portamento

0...100

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.
