[sdiy] paia midi to cv

[Jim Bob]

I built the paia midi to cv a few years ago, and it wasn't  precise.  I haven't measured it in years, but I believe for every  2 or 3 octaves it was off about .2 volts.  The paia instructions  even tell you NOT to use a multimeter when tuning it, and to tune it  hooked up to a VCO and do it by ear.  Maybe its because they know  the results wont be precise?  I tuned the paia VCO's to be in tune  w/ this range, and it was fine.  now Im building new VCO's and  other modules, and am wondering what to do about the midi to cv.  
  Is it usual that they are a little off like that?  Is it something  I should worry about?  I haven't worked w/ other midi/cv devices,  so dont know how exact it should be.
  
  thanks
