[sdiy] paia midi to cv

[Grant Richter]

Also bear in mind your $450 PAIA 9700 outperforms a $3000 Synthi or  
Putney in nearly every technical respect.
The oscillators are certainly more stable. Unmodified Synthis or  
Putneys have NO temperature compensation at all.
Just the nature of the beast, as Don Buchla said "You don't have  
retune any more often than a violin".
