Also i dont understand how to make it work this:
I seem not getting filter fm effect i would expect to (for ex Massive, Diva)Filter-FM
Turn MOD OSC B up to maximum and route it to WHEEL. In the TO
column, select WH as modulation input for FILTER (the bottom switch).
In the FILTER section, turn CUTOFF down to about 50. Push your
modulation wheel and experiment with all the controls in oscillator B.
