Comb Synth
Envelope
+/- 100. The ADSR envelope can be used to control the filter cutoff frequency,
adding to or subtracting from the setting on the Cutoff knob. With positive
envelope amounts, the envelope will increase the cutoff frequency above the setting
on the Cutoff knob. With negative amounts, the envelope will act as if it is inverted,
decreasing the cutoff frequency below the setting on the Cutoff knob.
At 0, the envelope will have no affect. At +100, the envelope will increase the cutoff
to the maximum frequency, even if the Cutoff knob is set to 0. At -100, the envelope
will decrease the cutoff to the minimum frequency, even if the Cutoff knob is set to
100.

Amplifier
These parameters control an ADSR envelope dedicated to the output volume. For a
graphic explaining ADSR envelopes, see the figure "ADSR Envelope," above.
Attack
0-100. This sets the attack time of the amplitude envelope, which controls how long
it takes from the moment that the key is pressed until the envelope reaches its peak.
Decay
0-100. This sets the decay time of the amplitude envelope, which controls how long
it takes the envelope to fall to the sustain level after the attack is complete.
