I will try those modulation possibilities with my brand new M15.

But making precise PW settings feels quite difficult compared to my 
Cwejman oscillator, which has conventional design.

Also, I find dialing small amounts of frequency modulation quite 
tricky; for example setting exactly the right amount of vibrato. In 
my opionion one of "Freq VC" controls should be less sensitive near 
zero modulation - perhaps sacrificing bipolar control.

Generally (and IMHO of course), I think Plan B modules knob response 
curves are sometimes impractical... I have M12, M13, M14, M15 and 
soon M10 and M23.
