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
ff
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.
