Something 'for control voltage output.

[petemoore]

  Any 'librarians' want to help me find reading fodder or offer some suggestions as what:
  Is cool
  Is easier
  Is ultimately possible
  Works out as worthwhile to drag around and use..
  As related to the control voltage outputs on my newly completed Tmax.
  came at 3 yesterday, and made tones at 10:30 tonight [what a relief], exciting when it fired right up and tuned right in...whew..Very fun to play, very hard to play a song on, like a violin sorta but harder to unitize pitch changes...or even hold a steady note.
  So now I have these CV jacks I wired up and waiting, I'm wondering what parameters to assign them to, I'm trying to figure out a practical application to build for it.
  My usual guitar effects being boost distorters, wah, phase and an Echo Park, octave etc., not really sure what I could do with any of these, I'm not even sure where I'd start to make a volume control.

You mean a Theremax? If so:

For volume  - a VCA. You could even use an overdrive/distortion/booster before it to progressively saturate a valve amp by proximity.

Or have two VCA's, send one an inverted CV, and you have a morphing proximity controlled A/B box - as you approach the antenna whatever is fed through the first VCA would get louder, the other quieter. Wild.

For a proximity sensitive wah - a notchpass VCF. Or make it multimode for synth type effects LP/BP/HP/NP.

For phase - I have a Roland modular voltage controlled phase schemo if you want it.

The LM13700 is a great building block for VC circuits:
