Hi Paul,
Thanks for the tips. Mine has one of those new replacement PCB boards you probably have heard of, which also has a CR2032 battery installed. It also has the midi retrofit installed, sold by the czech company I can't remember the name of. First on my list will be to check out the pitch wheel as you mentioned. Thanks again!

(why couldn't they give the Polysix a proper ventilation casing? Wouldn't that have made sense? Correct me if I'm wrong.)

> Hi, I have a Polysix that plays in tune at start-up, but after 30 or so minutes the "C", for example, is moved up the keyboard and plays where the "E" is. It does this consistently. Is this the problem with the OPTOCOUPLER? Is it really true that the Polysix needs to warm up fully before you can hear it's true tuning? I noticed that the back middle of the synth gets hot after ~30min. Is that normal? I've read some things, but am pretty new to the workings of the Polysix. Thanks for any insight. -Frank
