VCF IN & MIX IN jacks

These are analog audio inputs to the filter bank.

Patching to VCF IN mutes the internal VCO, replacing it with external audio.
Patching to MIX IN blends external audio with the internal tone generator.

Both can be used simultaneously

VOLUME knob

Sets the audio level at the main output
