VPM
Level
0.0-100.0. This is the output volume for the operator, and for the Patch as a whole.
The level knob has extra smoothing on the DSP, to ensure zipper-free modulation. If
you want to modulate the volume instantaneously via velocity, use the Vel Sens
control instead.
Vel Sens (Velocity Sensitivity)
0-100. This sets the sensitivity of output volume to velocity. A velocity of 127 will
always result in the maximum output level, as set by the Volume control; increasing
the Vel Sens will decrease the output volume for low velocities.
Modulators - OP 2, OP 3, and OP 4
The modulators in this Patch act in series, so that OP 4 controls OP 3, OP 3 controls
OP 2, and the resulting complex waveform controls the timbre of OP 1, the carrier.
Oscillator
Ratio
1.0-31.0. This selects the basic tuning for the oscillator. Changing the modulator's
ratio will affect the timbre of the carrier.
Fine
0.0-100.0. This allows you to fine-tune the ratio. You can think of this as the digits to
the right of the decimal. For instance, setting the Ratio to 3.0 and Fine to 53.0 results
in an actual ratio of 3.53. Setting Fine to 100 is the same as increasing the Ratio by 1.
Settings other than 0.0 can cause dramatic differences in the timbre of the carrier.
Detune
+/-10.00. This allows you to detune the oscillator, in cents (1/100 of a semitone).
Settings other than 0.0 can cause dramatic differences in the timbre of the carrier.
Waveform
Sine, Sine + 1st Harmonic, Sine + 1st & 2nd Harm. This sets the waveform for the
oscillator. Changing the modulator's waveform will affect the timbre of the carrier.
Feedback (OP 4 Only)
+/-100. Feedback allows the operator to self-modulate, which changes the shape of
the waveform. At high levels of feedback, the waveform will approach a sawtooth
shape.
Envelope
This envelope allows you to change the level of the modulator over time, which in
turn changes the timbre of the carrier. This affect is conceptually similar to the filter
envelope in an analog synth, although the actual change in timbre can be quite
different.
