The Pulse Width (duty cycle) of the square wave output can be changed. Changing this

changes the tone of the Square Wave. Note, this control is not an attenuator for the PW CV

socket described below.

PW CV Socket

This is a modulation input socket to control pulse width with an external voltage, or from

another circuit within the synth, e.g. Envelope signal.

CV (MODULATION)

There are two input sockets to modulate VCO pitch from a control voltage (CV). CV Input 1

is pre-Portamento (the modulation signal is affected by portamento). CV Input 2 is post-

Portamento (the modulation signal is un-affected by portamento).

Use either to modulate the pitch from another voltage such as EG or LFO.
