here's another.
While running through the voice calibration routine - i was not able to get two of my voices in calibration - however it only affects patches using strong resonance (a 'whistle' type sine wave) - so there are two dead voices when using any such patch... it's been a while since I did the cal so I'm not sure at which point during the procedure I had problems - but from memory it was around half way through. (i know that doesn't really help - but maybe that info isn't really necessary anyway) - is there a troubleshooting routine you might go through to figure out what might be amiss? All other patches sound good... except those using pure resonance (or i guess you might call it 'self oscillation' - if i'm using the term correctly?)
