Doepfer

The only possible difficulty, as I see it, is that the Hz/V 
sequencer will be sending a pitch CV to the A100 that increases 
exponentially as you adjust the pitch control upwards. (Do I have that 
right, and am I thinking about it backwards?) The A100 is expecting a 
linear voltage, so in the upper registers, the granularity of the 
pitch control will become progressively coarser - you might not have 
enough fine control to obtain the correct note without 
overshooting.

Like I said, though, I've never done this, and I probably don't know 
what I'm talking about :-)

It's also possible that my A121 exponential VCA suggestion might be 
exactly backwards - it might be how you convert from volt/octave to 
Hz/volt, rather than vice versa. It's too much thinking for me to do 
on a weekend.
