NORM/INVERT
Specifies the polarity of the envelope that is controlled by the CONTOUR knob. If this is set to “INVERT,”
the polarity is inverted. This is a very handy way of immediately transforming a sound just by effectively “flipping”
the envelope.
Experiment:Create a slow attack sound that you like. Now invert the envelope with the switch. Listen to
what happens to the sound. Pretty cool, right?
ENVELOPES
An envelope is a central method of shaping the sound of a synthesizer. Attack, decay, sustain and release are
the 4 main attributes of an envelope. Envelopes can control volume, filter, and other aspects of audio, and
voltage.
Triggered by a gate pulse/key/note on the envelope is then fired and will move through its stages until it is
either done, or re triggered by another gate or key.
Attack is the time the envelope takes to rise from silence to full volume.
Decay is the time the envelope takes to fall from full volume to the sustain level.
Sustain is the time the envelope takes to drop from the sustain level to the release
level. Release is the time the envelope takes to fall from the release level to silence.
FILTER ENVELOPE
ATTACK
Specifies the time (attack time) from when the key is pressed until the cutoff frequency reaches the maximum level.
DECAY
Specifies the time (decay time) from when the cutoff frequency reaches the maximum level until it decreases to
the sustain level.
SUSTAIN
Specifies the level (sustain level) that is held after the attack time and decay time have elapsed until the
key is released.
