digital perfection??? BLAH!!!

The perfection of analogue *is* the non-linearities!

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.
