Hi Florian. I am adjusting the trim pots of the VCO, but altough I am still trying to get an exact tonal scale, it's getting closer to that.

Is there a trim adjust on the D/A converter from the A190-2 midi interface module

For example, if I press a C3 then a C4 on the keyboard I hear another interval instead of an octave. I kept the system turned on for more than 20 minutes as I read it needs some time to make it get in tune.
