So what does the PCM IN module do?  Many real synths have audio inputs
so you can route a signal through the filters.

I do use jack-rack, but I have loftier goals in mind...

Granted, it may not be easy to convert a pitch to CV, but it should be
possible.  We have tuner software that detects a frequency, right? 
Let's map that frequency value to a CV value and run it into an
oscillator.  If it doesn't exist, I'd be willing to take a crack at
writing one, but not if I can't get ams to actually do anything.

So where are all the people who always chime in with "pd can do this?"
