AHDSR ENVELOPE STAGES. If the key is released during the Hold or Decay stages, the Release stage
begins.
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.

The amplitude envelope shape gives
important clues to the ear about what type of
sound is being produced.
