200e

The Continuum Voltage Converter has adjustable scaling, and one of  
the presets Haken Audio plans to have available out of the box is  
1.2v/octave, so it should work perfectly with Buchla oscillators.  
Output voltage ranges on the CVC are factory customizable within the  
voltage limits of -9.8v to +10.0v.

Otherwise, I think Gary's comments are spot on, especially the  
comment about MIDI performance.
