VPM
The output of a carrier is phase-modulated by a
modulator, and output through wave shape processing.
By controlling the wave shaping parameters and the
feedback gain, tonal changes that are different than
simple phase modulation can be produced.

1–3a

1–3a: Carrier
Wave
[Saw, Square, Triangle, Sine]
Selects the carrier waveform.
Level
[0…99]
Specifies the output level of the carrier. This will
determine the output level of the VPM oscillator.
AMS1 (Alternate Modulation 1 Source)
[Off…MIDI:CC#83]
Selects a modulation source 1 (

p.48 of this manual)
that will control “Level.”
Intensity (Level AMS1 Intensity)
[–99…+99]
Specifies the depth and direction of the effect of “AMS1.”
AMS2 (Alternate Modulation 2 Source)
[Off…MIDI:CC#83]
Selects a modulation source 2 (
☞
p.48 of this manual)
that will control “Level.”
Intensity (Level AMS2 Intensity)
[–99…+99]
Specifies the depth and direction of the effect of “AMS2.”
Wave Shape
[0…99]
Specifies the number of cycle of wave shaping.
As this value is increased, the number of cycles will
increase, causing more overtones to be added to the
high-frequency range of the sound.
1–3c: High Damp
H. D (High Damp)
[0…99]
Specifies the amount of attenuation that will be
applied to the high-frequency component of the
feedback signal within the comb filter.
As this value is increased, the tone will become more
mellow. Conversely, decreasing this value will
produce a brighter tone.
AMS (Alternate Modulation Source)
[Off…MIDI:CC#83]
Selects a modulation source (
☞
p.48 of this manual)
that will control “H. D.”
Intensity (High Damp AMS Intensity)
[–99…+99]
Specify the depth and direction in which “AMS” will
affect high damp.
