Indeed, the KBD TRACK is pointed at zero, and everything else is set to "standard".
Except WAVE-FORM at PW and PW/PWM to 10.
And offcourse the CUTOFF and RES to the settings needeed for adjustment.

In this case the VR8 were way off indeed.
(Ik know that for calibrating them, RES has to be set at 10 )

For some reason I don't get, for me, expected results.
What should the waveform look like?
I can get with turning the pots to something looking like triangels pointing to the right.
(Starting long side left and getting shorter to the right, until zero)

Or, when turning VR8 completely turned to the left, some kind of triangle waveform.
Many shapes between, are not trigerable.
