Thought I'd pass along two programs I've written which could be turned
into dedicated modules using the CVS board. I actually something
similiar to this some time back.

I have a Kurzweil Expressonmate ribbon and I wrote a program to parse
the MIDI and provide a CV out. Sometime later I found just the
Kurzweil Ribbon mechanism, model PC2, at Sweetwater for $50. I wrote
another program that sets one of the OUTs for 5.7 volts to the ribbon
and I use three of the INs to read the individual sections. I
incorporated a diode drop in the ribbon so that I could tell the
difference between no touch, and the low end contact. I use three
other OUTs for CV, trigger, and gate. I use one more IN as a center
adjustment so that you can tweak the center position of the ribbon
to 5.0 volts. An application like this only takes about half of the
parts on the board.

This mechanism is actually three separate ribbons so I had to piece
the sections into a continuous ribbon in the program. You could just
as easily output three separate ribbons. You don't have enough OUTs
for trigger and gates, but you could easily use the LED outputs for
the additonal triggers and have three complete ribbons. START could
be used to toggle between a single or triple configuration. You could
also expand the capabilities with different modes similar to the
Expressionmate like return to center, absolute, relative, etc.

Hopefully someday information on these types of dedicated applications
will be posted. Food for thought.
