VPM 4 OP Stack
Attack
0-100. This sets the attack time of the amplitude envelope, which controls how long
it takes from the moment that the key is pressed until the envelope reaches its peak.
Decay
0-100. This sets the decay time of the amplitude envelope, which controls how long
it takes the envelope to fall to the sustain level after the attack is complete.
Sustain
0-100. This sets the sustain level for the amplitude envelope. After the decay time is
complete, the envelope will stay at this level as long as the note is held.
Release
0-100. This sets the release time of the amplitude envelope, which controls how
long it takes the envelope to fall to zero after the note is released.
Level
0.0-100.0. This is the output volume for the operator, which controls the overall
amount of modulation to the carrier.
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.
Vibrato
Frequency
0.0-20.0 Hz. This controls the initial speed of the vibrato.
Frequency Mod
List of Modulation Sources. This sets the modulation source for controlling the
vibrato frequency. For a complete list, please see "Modulation Sources" on page 2.
Amount
0.0-10.0Hz. This sets the amount, in Hz, by which the mod source affects the
vibrato frequency. When the mod source is at its maximum value, it will add this
amount to the setting on the Frequency knob.
Depth
0-100. This controls the initial depth of the vibrato–the amount of pitch modulation.
