EG
EG: Envelope Generator
The EG controls the cutoff frequency of the filter
and temporal change of other parameters.
Modulation is applied to oscillators 1 and 2, the
VCF and the LFO. The depth of the effect and
other parameters are set using the PITCH EG INT knob (MODULATION), the EG
INT knob (FILTER), the RATE knob (LFO), and the INT knob (LFO).
ATTACK knob
The ATTACK specifies the time required for the EG to reach its maximum level once
a new note is played.
DECAY knob
The DECAY specifies the time required for the EG to fall to the preset Sustain level
once the Attack portion of the EG is complete.
SUSTAIN knob
The SUSTAIN specifies the level that will be maintained while the key is held down
(or a trigger is applied).
RELEASE knob
The RELEASE specifies the time required for the EG to reach its minimum level (zero)
once the key or trigger is released.
