Input " is normally connected to a control voltage
governing pitch (for instance from a MIDI-CV interface,
or a master keyboard with a 1V / octave output).
H Socket CV 1 " is designed as a normalled
socket, connected to whatever CV is present
on the internal System Bus. This CV (for
instance from a master keyboard) governs
the VCO’s pitch, unless a plug is inserted in
socket " .
If you put a control voltage (for instance from
an LFO) into socket " , the System Bus is
disconnected, and the VCO’s pitch is control-
led by this voltage.
As a rule, input § is used for FM - for vibrato, auto-
bend, or other pitch-related effects; the level of control
voltage passing to the VCO is adjusted with attenuator
3
.
$ PW CV 1 • % PW CV 2
Sockets $ and % are the Voltage Control Inputs for
the Pulse Width of the square wave that the VCO
produces. These voltages are summed. The level of
CV input % can be controlled with knob 5.
& / ( )
These four sockets are the VCO outputs: Square
wave (&), Sawtooth (/), Triangle (() and Sine wave
()).
Pitch is always the same for each of these outputs.
