Calibration
The module is factory-calibrated using precision
voltage sources. Follow this procedure only if you want
to compensate for inaccuracies in your CV sources, or if
your module has lost its calibration settings following a
fault or the installation of alternative firmware.
To calibrate the unit:
1.
Disconnect all CV inputs.
2.
Connect the note CV output of a well-calibrated
keyboard interface or MIDI-CV converter to the
V/OCT input jack.
3.
Connect a patch cable to the
FREQ CV input. Leave
the other end of the cable unplugged.
4.
Press and hold both the
POLY and MODE buttons for
two seconds. The
POLY LED will blink amber.
5.
Play a C2 note, or send a 1V signal from your CV
source.
6.
Press the
POLY button. The MODE LED will blink
amber.
7.
Play a C4 note, or send a 3V signal from your CV
source.
8.
Press the
POLY button.
If calibration was successful, the module will return to
its normal state. Otherwise, both LEDs will blink red for
a few seconds.
