Ha! :) Don't take my "digital perfection" remark the wrong way. Counting the Evolver, I own five *real* analog synths, in addition to the digital gear. That should let you know where I stand on analog! No... unfortunately, the filter tuning and interval calibration on my Evolver is really bad. "Bad" as in "unplayable", not just "it's several cents off". The best I've been able to manage is to get it somewhat tolerable over about a 1-1/2 octave range, and that's with the Filter "Key Amount" set at 73 rather than the 72 quoted in the manual. I have been extremely careful to ensure that nothing (Velocity, Envelopes, LFO, etc.) is modulating Filter Cutoff, or anything else for that matter. I've also made sure that Oscillator Glide is off. (Did you know that the Filter Cutoff follows Osc 1 Glide? Cool!). I tried the 1+5, 4+7, and 4+8 button combinations again, too - one at a time. No improvement. I also isolated each filter, as suggested earlier, but again no luck. I have a very early unit (#9), so maybe this will be a simple matter of an OS update or some other calibration. In any case, I'll ask Dave about it when he gets back from Europe soon. Thanks.
