I lately experienced some tuning drift with my MS10. I used it for drones the other day, patching the wheel to trigger input. The tuning didn't last two minutes. I had to frequently hit the key so it doens't have the time to drift.
I read this on korganalog.net, different method same results.
It looks like a known issue.For steady drones you can patch Kbd Trig Out or ESP Trig Out to Initial Gain (but watch out for oscillator drift, about minus 1 semitone after 20 minutes, i learnt the hard way after recording 7 25 minute drones, and then very unsucessfully trying to put them together in AudioMulch!!!) If you dont want any pitch drift, then use the old sellotape/pen knife on a key trick!
Is it something that be fixed?
Anyone have stable drones? How?
