Here you find the options for tuning the VCF filter voices.

Warning! If one of the VCF tuning options is selected,
M plays a tone for audible orientation. Please turn
down the overall volume before.

Use the display encoder 1 to change the voice, it will stay
at resonance mode to tune. Use encoder 2 to tweak coeffi-
cient (they are reverse-meaning, i.e. to tune higher, you
need to set the oefficient LOWER and vice versa. Save the
tune coefficients with the settings by pressing

will load your settings on start, so no need to retune the
VCFs after fine-tuning anymore.
Please also remember about thermal drift, so at the start
with cold VCFs they will be tuned higher on about 2 semi-
tones. The best results could be achieved, when you will
tune the unit after ca. 15-20 minutes of warming up.
The best way is to make VCF fine-tuned on this screen
against C5 1042.5 Hz @ ~20C, is using software tuner. In
that case, the settings Cutoff 64 / Resonance 127 / Key
track 63 will exactly follow the equal-tempered scale
within 4-5 octaves (from C2 to C7 roughly). Lower C2 will
be under tune, higher C6 possibly C7 - over tune.

Of course, environment temperature plays a role. If
your studio room is on the top floor and it´s sum-
mer, we recommend to better tune the M in the
night.
