EG (ENVELOPE GENERATOR) (continued)
SUSTAIN
When ON, the Envelope signal will hold at its maximum level for the duration 
a note is held, similar to an organ. When OFF, the Attack stage immediately 
moves to the Decay stage when complete, or when a note is released 
depending on which occurs rst.
NOTE: When the Sustain switch is set to ON, overlapping notes from the 
Keyboard or MIDI notes do not retrigger the EG, allowing legato phrasing. 
When the Sustain switch is set to OFF, each note played on the Keyboard 
or MIDI note retriggers the EG.
 
DECAY
The DECAY control species the time it takes for the Envelope to descend 
from its current or maximum level to zero. Fast decay times are useful for 
creating punchy staccato notes, while longer decay times allow a note to 
ring out or fade away slowly.
Turn the DECAY control to the left for faster decay times, and to the right 
for longer decay times.
VCA (VOLTAGE CONTROLLED AMPLIFIER)
A VCA is used to dynamically control the volume of your Mother-32. It either follows a volume curve 
determined by your EG settings or is set to ON, which causes the VCA to remain xed at its maximum value.
VCA MODE
This switch determines whether the VCA is modulated by the Envelope or is 
simply held at its maximum level.
 
EG
The EG setting is ideal in most applications. This uses the curve of the Envelope 
Generator to add dynamic characteristics to a sound, which can be used for 
everything from slow volume swells to snappy plucked sounds.
 
ON
When set to ON, Mother-32’s audio signal is allowed to pass without the need for a Gate or note ON message 
to occur. This is ideal for drones and continuously evolving modulated sounds, but is also useful for eliciting 
new behavior and sounds from an existing sequence.
VOLUME
Adjusts the main output level for both the patchbay VCA output, and 1/4” 
AUDIO/HEADPHONE output on the back of the Mother-32. Rotating the 
control fully clockwise produces the maximum output. Rotating the control 
fully counterclockwise silences the instrument.
