Voltage Controlled Oscillators 

The three analogue VCOs are basically identical. Most of 

the controls are straight forward: Tune, Pulse Width, Level.

Glide is like portamento - to allow note to slowly bend up or 

down to the next new note.

SUBS 

Oscillators 1 and 2 have Sub-Osc outputs. These are 

square wave outputs that are 1,2 and 3 octaves below the 

main Saw and Square outputs.

Typically use Sub-Osc mixed with the VCO outputs to really 

beef up the sound.

Note on pitch scaling: The VCOs have been calibrated with 

MIDI Pitch CV patched to each VCO’s pitch CV input using 

the pin matrix, with 10K resistor pins. If you use 0 Ohm pins 

or other pin values, or use patch cables, this could a

ect 

pitch scaling. So if normal music temperament is needed, 

use 10K pins. If you are making crazy sounds, then don’t 

worry.

Note on glide: Adding resistance between the CV source 

and the pitch CV input can add a little extra portamento.
