Specifies how decay time is calculated.
When 1, indicates decay time is the time it would take to get from 0dBs to -oo, NOT the time to reach current sustain (as when 0). Default is 1. 1 and 0 must be used at least in Sforzando 1.952, true/false or on/off don’t appear to be supported.
In other words, under default behavior, the decay slope is fixed, and the higher the sustain level of the envelope, the less time the decay stage will actually take. Changing ampeg_sustain will change the actual duration of the decay stage as well, up to a maximum of the full ampeg_decay value at ampeg_sustain equal to 0.
Setting this to false will make the decay always happen during the entire
time period specified by
ampeg_decay, regardless of the current
