meter with the difference that its intensity is velocity
based. Use this feature to give a more expressive charac-
ter to the sound. When you hit the keys smoothly, only
minimal modulation is applied. When you hit them
harder, the modulation amount also gets stronger.
w
The overall modulation applied to the filter’s
cutoff frequency is calculated as the sum of both
the ENV F Amount and Filter Velocity parame-
ters. Therefore you should always bear this total
in mind, especially when the filter does not be-
have as you expect. You can also create inte-
resting effects by setting one parameter to a posi-
tive and the other to a negative amount.
The Amplifier Section (VCA)
To understand the operation of this unit, it is important
to know that the Amplifier Envelope (ENV A) is always
acting as a modulation source for the volume. This
means that an audio signal can only pass through if the
Amp Envelope is triggered and opened.
Drive
0...127
Determines the amount of saturation that is added to the
signal. If set to 0, saturation will be minimum or, in
other words, the signal will remain nearly clean. Lower
values will add some harmonics to the signal, resulting
in a warm character. Increasing the value will bring in
more and more distortion, suitable for harder lead
sounds and effects.

Is Drive Curve set to NONE, this parameter has
no effect.
