T.Henry's VCO Deluxe tuning

[scopey at hooked.net]

thanks for the reply, Jim.  The deluxe VCO circuit in question is
courtesy of Thomas Henry (Midwest Analog Products-- check the website). 
It's in his book; I highly recommend it, especially if you have some
spare 3340's.  Heck, I recommend it anyway.  It's really great!

to be more specific: the VCO circuit has a v/octave trimpot and a high
frequency trimpot.  the Paia MIDI-cv card has a DAC trimpot, and that's
it.  Paia's instructions for tuning your VCO with the MIDI converter
involve:

1)play a low note; tune it with a reference by adjusting the trim on the
VCO
2)play a high note(preferably the same note in a higher octave i think);
tune it to the reference by tweaking the DAC trimpot
3)repeat 1 and 2 until the keyboard (MIDI controller) is able to play in
tune over the entire range.

i know somebody out there has gone through this....(?)
