11. Synthesis basics: Envelopes
Page 91
After the envelope has reached full level, it starts to fall back again. How long this should take, is set with
the Decay parameter.
the Decay parameter.
The level of the envelope does not necessarily have to fall all the way back to zero level at the end of the
Decay. Instead, the ADSR-envelope has a Sustain setting used to determine the level the envelope should
rest at, after the Decay. If you for example want to create a flute sound, you would have a fairly high Sus-
tain setting on your Volume envelope, since a flute tone basically stays at a steady level for as long as you
play it. 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.
