The CV-5 works with any monphonic analog synthesizers which conform to the 1 Volt per octave or Hertz per Volt scale standards. The unit can be confiigured by sending midi program changes. The CV-6 goes well beyond most simple midi-to-CV converters and offers high quality portamento, fast note response times, filter and auxiliary outputs, dynamic audio processing (volume and pan control), syncable LFO, vibrato, sample and hold, pitch bend, and DIN sync output. With five CV outs, it can actually be used to control two synthesizers."
