Specifies how decay time is calculated.
When set to 1, the decay slope is fixed, and the higher the sustain level of the envelope, the less time the decay stage will actually take. Changing fileg_sustain will change the actual duration of the decay stage as well, up to a maximum of the full fileg_decay value at fileg_sustain equal to 0.
Setting this to 0 will make the decay always happen during the entire
time period specified by
fileg_decay, regardless of the current
