These are sockets used to modulate the pitch of the VCO with an external voltage, or from
another circuit within the synth, e.g. Envelope signal.
Take the CV from the external source, and patch it into the socket. Use the CV Control knob
to set the strength of modulation to the VCO pitch.
Waveform select switch
This switch determines whether Saw or Square is fed to the Voice Gate circuit.
Additional VCO Sockets and switches (vary depending on VCO)
MIDI /Free Run switch (VCOs 2 and 4 only)
When set to MIDI the VCO will respond to MIDI notes.
When set to free run it is unaffected by MIDI notes. This is ideal when using this VCO for
effects or modulation.
SYNC In (VCOs 1 and 3 only)
