AMPLIFIER ENVELOPE
This Envelope controls the overall volume characteristics of the sound over time.
A (Attack Time): It is the time required for the Envelope to rise from zero to maximum level
when a note is pressed. The higher the attack time, the longer it takes for the amplitude to
rise to maximum.
D (Decay Time): It is the time required for the Envelope to fall from its maximum level (end
of Attack) to the Sustain Level. The higher the setting, the longer the Decay.
S (Sustain Level): The sound will stay at this level as long as a note is held.
When the Sustain is set at maximum, the Decay is having no effect.
R (Release Time): It is the time required for the Envelope to fall from the Sustain Level to
zero. This controls how quickly the sound reaches silence from the moment a note is released.
Percussive sounds typically have short Attack and Decay times.
