VPM 2 OP

VPM 2 OP
This Patch is a two-operator VPM synthesizer. VPM stands for Virtual Phase
Modulation, in which the phase of one oscillator (the Carrier) is modulated by
another oscillator (the Modulator), producing a complex timbre. The combination
of an oscillator and its amplitude envelope is known as an "operator." VPM is
particularly well-suited to bells and electric pianos, although it can produce many
other sounds as well.

Carrier - OP 1
Oscillator
The carrier operator determines the basic pitch and amplitude envelope. The
modulator operator changes the timbre of this oscillator.
Ratio
1.0-31.0. This selects the basic tuning for the oscillator.
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.
Detune
+/-10.00. This allows you to detune the oscillator, in cents (1/100 of a semitone).
Waveform
Sine, Sine + 1st Harmonic, Sine + 1st & 2nd Harm. This sets the waveform for the
oscillator.
Envelope
This envelope controls the overall output level of the Patch.
