On the other hand, for a piano sound, you would want a sustain level of “0”, since a piano sound decays
to silence if you hold the key long enough.
Please note that the sustain parameter represents a level, but all other envelope parameters represent times.
As described above, the envelope stays at the sustain level until the key is released. It then falls back to
zero level. The time it should take for this to happen is set with the Release parameter, which works just
as the decay, only it is not applied until you lift your finger off the key(s).
• If you set sustain to full level, the decay setting is of no importance since the volume of the sound is
never lowered.
