Anatomy of an Envelope
An envelope creates a variable control signal. It can be used, for instance, to modulate the filter settings
of a sound over a given period of time.
For drum programs, use the AD/AHDS selector to select an AD or AHDS envelope.
Keygroup programs always use AHDS envelopes.
With AHDS envelopes, the following happens when you trigger a sample:
1. Within the period of time you have defined with the Attack (Atk) parameter, the sample volume rises
to its maximum value.
2. The sample’s maximum volume will be maintained during the Hold phase.
3. During the Decay phase, the sample’s volume will gradually drop to the sustain level.
4. The sample’s volume will stay at the sustain level (Sust) until the pad is released.
