Creating a pattern
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 pattern from scratch by specifying the sound
and rhythm pattern for each part. Either way, the ER-1mk
II
makes it easy for you to create your own original rhythm pat-
terns.
If you wish to save a pattern you create, you must perform
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 rhythm). Strike the part
keys to hear each sound, and use the knobs and keys to edit the
sounds. 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.45) 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.42 "About MIDI").
If the sound does not change when you rotate a knob or
switch the setting of a key, either that knob or key is not
valid for that part, or the Motion Sequence function (p.28
"Motion Sequence") is operating.

Oscillator and amp parameters

The parameters that are valid for each part are shown in the
following diagram.
· Percussion Synthesizer part x 4
· Audio In part x 2
· Hi-hat part x 2
· Crash Cymbal part
· Hand clap part
· Accent part
The Audio In parts are valid only when a signal is being
input to the audio input jacks.
Although the sounds of the CLOSE and OPEN hi-hat parts
can be edited independently, they cannot be sounded si-
multaneously. If both are triggered in the same step, the
Open hi-hat will sound.
Similarly, the sounds of the Crash Cymbal part and the
Handclap part can be edited independently, but cannot
be sounded simultaneously. If both are triggered in the
same step, the Handclap part will sound.

OSCILLATOR

This specifies the oscillator waveform and pitch.
WAVE sine wave, triangle wave
Select the basic waveform. Each time you press the key, the
waveform will alternate. A sine wave produces a mild (col-
orless) sound. A triangle wave is slightly brighter than a
sine wave.
PITCH 20 Hz...12,000 Hz
Adjust the pitch. Rotating the knob toward the left will lower
the pitch, and rotating it toward the right will raise the pitch.
MOD TYPE (modulation type)
(Saw Down) ... (Envelope)
Select the type of pitch modulation.
(Saw Down): The pitch will fall cyclically.
(Square): Two pitches will alternate cyclically.
(Triangle): The pitch will rise and fall cyclically.
(Sample & Hold): The pitch will change randomly.
(Noise): A noise component will be cyclically added to
the pitch. This is effective when creating snare
drum sounds.
(Envelope): An envelope will be applied to the pitch.
This is effective when creating kick or tom
sounds.
MOD DEPTH (modulation depth) –100...0...100
Adjust the depth and direction of the pitch modulation. Posi-
tive (+) settings (right) and negative (–) settings (left) will
invert the direction of the pitch modulation effect. When
the knob is positioned in the center (0), the Modulation Type
and Modulation Speed will have no effect.
MOD SPEED (modulation speed)
0.1 Hz...5,000 Hz
Adjust the speed of pitch modulation. Rotating the knob
toward the right will speed up the pitch modulation, al-
lowing you to apply cross-modulation effects.

AMP

These parameters control the volume and panning.
DECAY 0...100
Adjust the speed at which the volume will decay. For Au-
dio In parts, this will function as a gate time (duration of
the sound) synchronized to the tempo.
PAN L...R
Set the stereo position (panpot) of the sound. When the knob
is located in the center, the sound will be heard from the
center. Rotating the knob toward the left will place the sound
toward the left, and rotating the knob toward the right will
place the sound toward the right.
