hello ernst,
i am not sure, but one of my a111's had a similar
problem with the PW function (PW knob or pwm knob
+input) and the sine, triangle waveforms, and it
turned out to be a broken cem3340 chip.
but, i had again a similar problem with another of my
a111's (i have 8...) and all i had to do is first
insert and then unplug a patchcord in the hard sync
input of the a111. try this, maybe this will fix the
problem. dieter had once told me the reason for
thishard sync issue.. but i cannot remember it now...
just try this patchcord trick with the hard sync( and
softsync) jacks of your a111.
regards,
bakis.
