Amp Envelope Modulation Section
The Modulation controls allow real-time MIDI control of the Attack, Decay and Release of the Amplitude
envelope.
Controller
Choose a MIDI controller, channel aftertouch, or velocity to provide a modulation source for the Amp
Envelope parameters. There are 25 possibilities, including none.
Invert
This inverts the action of the selected controller. Example: Normally, higher velocity values lengthen the
Decay time. When inverted, higher velocity values shorten the Decay time.
Attack, Decay, Release
The Attack, Decay, and Release parameters have four different modulation levels. Each parameter is
independent of the others.
Off :
The parameter ignores the MIDI Controller.
Low: Very light response to the MIDI Controller. Example: With Invert off and Attack being modulated, high
velocity notes will extend the attack time a little bit.
Med:
Moderate response to the MIDI Controller. In the example above, high velocity notes will extend the
attack time by considerably more.
High:
Provides the maximum parameter variation based on the MIDI Controller value. Example: With Invert
off and Release being modulated, higher velocities will give much longer release times. With Invert on, higher
velocities will give much shorter release times.
Note that the effect of modulation depends on the envelope settings. Example: If the envelope Attack time is
zero, the Mod controller won’t affect it, as you can’t make zero longer or shorter. Once you enter a parameter
higher than zero, this controller will then have an effect. Shorter Attack times result in very light changes with
the Mod controller, while longer times result in more drastic changes with the Mod controller. The Decay
and Release settings work similarly.
