Program Edit
When this is set to 0, playing different notes on the key‐
board won't change the pitch at all; it will be as if you're
always playing C4. This can be useful for special effects
sounds, for instance.
Pitch JS+X
This specifies in semitones mitones how much the pitch will
change when the joystick is moved to the right (or when a
pitch bend message is received). For normal pitch bend, set
this to a positive value.
For example, if you set this to +12 and move the joystick all
the way to the right, the pitch will rise one octave above the
original pitch.
Pitch JS–X
This specifies in semitones how the pitch will change when
the joystick is moved to the left (or when a pitch bend mes‐
sage is received). For normal pitch bend, set this to a nega‐
tive value.
For example, if you set this to ‐60 and move the joystick all
the way to the left, the pitch will fall five octaves below the
original pitch. You can use this to create guitar‐style down‐
ward swoops.
Portamento
These parameters adjust portamento settings for oscillator 1.
Portamento (Portamento Enable)
Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.
On: Turns on Portamento, so that pitch glides smoothly
between notes.
Off: Turns off Portamento. This is the default state.
PortaFingr (Portamento Fingered)
This parameter allows you to control Portamento through
your playing style. When it's enabled, playing legato will
turn on Portamento, and playing detached will turn it off
again.
This option is only available when "Portamento Enable" is
turned on.
On: Turns on Fingered Portamento.
Off: Turns off Fingered Portamento.
PortaMode (Portamento Mode)
Rate means that Portamento will always take the same
amount of time to glide a given distance in pitch ‐ for
instance, one second per octave. Put another way, gliding
several octaves will take much longer than gliding a half‐
step.
Time means that Portamento will always take the same
amount of time to glide from one note to another, regardless
of the difference in pitch. This is especially useful when

playing chords, since it ensures that each note in the chord
will end its glide at the same time.
PortaTime (Portamento Time)
This controls the portamento time. Higher values mean lon‐
ger times, for slower changes in pitch.
This option is only available when "Portamento Enable" is
turned on.
LFO
These parameters make LFO settings for oscillator 1.
LFO1
This selects the basic LFO1 waveform.
Please see "LFO waveform" on page 20.
Most of the waveforms should be self‐explanatory, but a few
will benefit from more details:
Guitar is intended for guitar vibrato, and its shape is specif‐
ically tuned for this purpose. The waveform is positive‐only,
so that when used for pitch, it will only bend up, and not
down.
Random1 (S/H) generates traditional sample and hold
waveforms, in which the level changes randomly at fixed
intervals of time.
Random2 (S/H) randomizes both the levels and the timing.
Random3 (S/H) generates a pulse wave with random tim‐
ing. It's the opposite of traditional sample and hold; the tim‐
ing varies, but the levels don't.
Random4–6 (Continuous) are smoothed versions of Ran‐
dom 1–3, with ramps instead of steps. You can use them to
create more gentle random variations.
LFO2
This selects the basic LFO2 waveform, as shown in the
graphic below
