Refer to the following diagrams and definitions to understand how each
parameter affects dynamics.
• Attack: varies the VCA envelope attack time from 0 to 163.69
seconds.
• Hold: sets the duration of the peak, from 0 to 21.69 seconds. If a
key is held down longer than the hold duration, the decay phase will
begin. If a key is released during the hold duration, the release phase
will begin.
• Decay: varies the initial decay time from 0 to 163.69 seconds.
• Sus: (Sustain) varies the envelope sustain level from 0 to 100% of
the peak level.
• Rel: (Release) varies the release time from 0 to 163.69 seconds.
