The Out module is the output stage which feeds a standard mono 1/4 inch audio jack.
The Out module receives its audio input from the VCF output. It contains a final amplifier with voltage controlled volume and a classical spring reverb unit to add reverb. The amount of reverb added is also voltage controllable.
Volume is meant to be controlled by the standard MIDI controller number 7. Reverb should be controlled by MIDI controller number 91.
