Actually, tones are quite stable even during the first 20 minutes, but
the synth is not in tune generally. Also, an octave is a quite stable
major 7 interval for the first 20 minutes, until suddenly, the synth
goes into tune and then the octave is correct as well. I'll check
tonight if a single generated tone changes a lot during the first 10
sec.
All six voices are affected. If I play a chord when it suddenly slides
out of pitch, all notes follow. It actually sounds like I'm turning
the pitch wheel. (I disconnected the pitch wheel, btw, just to be sure
it wasn't playing tricks on me).
It is not related to the MG setting and I've played around with all
three - VCA, VCF and VCO. I'm quite sure it's not affected by the
waveform setting either (whether I use a saw or a pulse) but I'll
double check that tonight. The PWM setting does not make any
difference.
Does this give you any clues? Thanks for helping!
