The law setting gives a choice of:
V/oct - volts per octave (Moog / Roland type)
Hz/V - Hertz per volt (Korg / Yamaha type)
gate - allows the use of a CV output as a gate output
As the CV outputs are capable of outputting a higher voltage than the gate outputs, the gate
option can be used to drive synths which need a higher level gate voltage than 5 volts.
The Vscale setting is a soft adjustment of the voltage scaling of the CV outputs, for use with
synths with the volts-per-octave law.
It has no effect if the hertz per volt law is used, in which case the Vscale value is replaced
with an Offset value. The offset value is a small DC adjustment applied to the voltage
output. Because of the way linear CV oscillators work, this has the same effect for a linear
oscillator as a change of Vscale for an expo VCO.
Although many synths use “1 volt” per octave in theory, variations in calibration of test
equipment mean that often there are slight differences in scaling between different synths.
The Vscale setting allows you to adjust each CV output individually to get all your synths in
tune, without having to laboriously range and scale each one to suit the internal scaling of
your Cirklon’s digital to analogue convertor.

In the CVIO config view, you can manually adjust the value by turning the encoder, but this
is slow, and not easily done by ear.
If you press the encoder, you will access a sub-page where you can adjust the scaling by
tuning two reference notes against the same notes played on a MIDI-attached synth which
you know to be in tune. Or you could use a digital tuner.
