Roll
This turns the Roll (successive strike) effect on (lit) or off
(dark) for each part. The roll interval is determined by the
tempo of the pattern and by the roll type (see p.32 Set-
ting the roll type). If you press and hold a part key when
Roll is on, roll playback will continue as long as you con-
tinue holding the part key.
Effect
This turns the effect on (lit) or off (dark) for each part.
Motion Seq (motion sequence)
This records and plays back knob movements. Each time
you press this key, it will alternate between on (Smooth
lit), on (Trig Hold lit), and off (dark). (see p.34 Playing
motion sequences)
Synth part
Synth Filter section
The filter processes the sound produced by the oscillator to
make it less bright, etc.
Cutoff 0...127
Set the cutoff frequency of the low-pass filter. Overtones
higher than the cutoff frequency will be cut, making the
sound more mellow.
Depending on the settings of this parameter, the
sound may be distorted or you may hear virtually no
sound.
Resonance 0...127
This parameter adds character to the sound by boosting
the region around the cutoff frequency. If you raise the
resonance and turn the Cutoff knob (or adjust EG Int and
EG Time), you will hear the typical "meow-ing" sound
typical of analog synthesizers.
If the resonance is raised, the sound may be dis-
torted depending on the cutoff frequency or on the
pitch that you play.
EG Int (EG intensity) 64...63
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.
Drive 0 ... 127
This adjusts the degree of distortion for the sound of the
filter. By using this parameter in conjunction with the synth
filter Cutoff and Resonance to make the sound distort, you
can generate overtones that were not present in the origi-
nal waveform.
Part Common section
EG Time 0...127
This has the same function as for a drum part (see p.27).
By setting EG Int in the negative direction, this can be used
as the attack time.
Glide 0...127
Glide (also called portamento) is a function that, when
the gate time length extends beyond the timing of the next
note, smoothly changes the pitch from the previous note
to the next note without re-triggering.
The time from when the next note is played until that pitch
is reached can be specified as a multiple of steps (0, 1/4,
1/2, 1, 2, 4, 8, 16, 32, 64, 128 times) relative to the pattern
tempo. As this value increases, a longer time will be re-
quired before the target pitch is reached. Conversely if this
value is set to 0, the target pitch will be reached immedi-
ately, and since the note is not retriggered, this is suitable
when you wish to simulate a legato performance on a bass,
etc.
For some settings, slight noise may occur.
The Glide effect will be defeated when the Roll key
is on (lit).
Level 0...127
This has the same function as for a drum part (see p.27).
Pan L64...r63
This has the same function as for a drum part (see p.27).
Amp EG
This has the same function as for a drum part (see p.27).
Roll
This has the same function as for a drum part (see p.28).
When Roll is on, the sound will be played as a roll as long
as you hold down the step key (if the keyboard function is
on).
Effect
This has the same function as for a drum part (see p.28).
Motion Seq (motion sequence)
This lets you record and play back knob movements of
the Part Common section and Synthesizer section. Each
time you press this, it will alternate between on (Smooth
lit), off (Trig Hold lit), and off (dark). (See p.34 Playing a
motion sequence)
Accent parts
Part Common section
Level 0...127
This adjusts the accent level (the amount of volume em-
phasis when accent is on). (See p.34 Adding accents to
the pattern(Accent)) Effect or delay edit.
