Amplifier Envelope Selector buttons: The AGateR, ADSR, and GateR buttons define which
of the ADSR envelope generator controls have an effect on the amplifier envelope (see
Using the Envelope to Control the ES1 Amplifier).
Using the ES1 Envelope Parameters
The ES1 features an attack, decay, sustain, and release (ADSR) envelope that can shape
the filter cutoff and the level of the sound over time.
Attack slider: Determines the amount of time that it takes for the envelope to reach
the initial, desired level.
Decay slider: Determines how long it takes for the envelope to fall to the sustain level,
following the initial attack time.
Sustain slider: Sets the sustain level, which is held until the keyboard key is released.
Release slider: Determines the length of time that it takes the envelope to fall from the
sustain level to a level of zero.
Using the Envelope to Control ES1 Cutoff Frequency
The envelope generator modulates the filter cutoff frequency over the duration of a note.
The intensity of this modulation—and how it responds to velocity information—is set
by the ADSR via Vel slider arrows (in the Filter Parameters section).
