In order to use the internal bus, you must make
settings in the P03–2: TIMBRE – OUT tab page to
assign the timbre output to the internal bus.
3: OSC Mod

OSC MOD

[Waveform, Cross, Unison, VPM]
Selects the modulation type for oscillator 1.
You can’t apply modulation if “Wave” is set to
Formant, Noise, Synth PCM, Drum PCM, or Au-
dio In. This field will be shown as Waveform.
The maximum number of voices will change de-
pending on the combination of “Wave” and “OSC
Mod” settings.
Waveform (Waveform Modulation)
Use “Control1” to modify the waveform.
For details on how the waveform will change, refer to
p.82 “Wave (OSC1 Wave) Ü WAVE [
π
], [†] á.”
Cross (Cross Modulation)
Cross Modulation uses the output waveform of oscilla-
tor 2 (the modulator) to modulate the frequency of oscil-
lator 1 (the carrier) at high speed to produce a
modulated sound. The waveform selected by “Wave”
will be the carrier.
If “Wave” is Saw, Squ, Tri, or Sin, you can adjust the fol-
lowing parameters for the selected waveform.
Control1: ModDepth (Cross Modulation Depth) [000…127]
Adjusts the depth of cross modulation.
Control2: LFO1Mod (LFO1 Modulation Intensity) [000…127]
Adjusts the depth to which LFO1 will vary the
amount of cross modulation. Pitch Modulation var-
ies the pitch from the basic pitch for an equal dis-
tance up/down in terms of musical notes. In
contrast, Cross Modulation varies the pitch from the
basic pitch for an equal distance up/down in terms
of frequency.
Unison
Unison skews the pitch of five oscillators within a single
oscillator and outputs them together to create a richer
sound. This is not to be confused with the unison param-
eter under voice (P04:VOICE-UNISON) which requires
using additional voices of polyphony.
If “Wave” is Saw, Squ, Tri, or Sin, you can adjust the fol-
lowing parameters for the selected waveform.
Control1: Detune (Unison Detune) [000…127]
Adjusts the difference in pitch between the unison
oscillators. Higher values will broaden the pitch dif-
ference between the oscillators, producing a richer
sound.
Control2: Phase (Oscillator Phase) [000…127]
Specifies the phase of each oscillator at note-on. This
will affect the tone of the attack. A setting of 127 will
change the pitch and volume.
VPM
VPM (Variable Phase Modulation) uses a sine wave at a
harmonic (integer) multiple of the oscillator 1 funda-
mental to modulate the phase of oscillator 1, producing
metallic-sounding overtones. In contrast to Cross Mod-
ulation which produces sounds that have a modulating
character in the waveform, VPM uses a sine wave at a
harmonic multiple of oscillator 1 to modulate the phase
of oscillator 1, meaning that the waveform will remain
static while overtones are added. The sine wave used for
modulation is built into oscillator 1, so the waveform of
oscillator 2 will not affect the sound of oscillator 1.
If “Wave” is Saw, Squ, Tri, or Sin, you can adjust the fol-
lowing parameters for the selected waveform.
