this auction"Vesta Kaza midi to cv converter that was originally made to accompany a sampler by the same company. It funtions as a standard 1v/oct midi to cv converter, but it only works over 3 octaves. Which would be perfect if you had a compact keyboard controller, or triggering a bass mono synth line, or if you were triggering a freqbox (which only has a 3 octave triggering range, at best. ) Operation is very simple, by setting the desired highest note on your keyboard or sequencer, it will convert all midi notes 3 octaves below set point. limited range, but where are you going to find a converter at this price? I have been using this with a little phatty, and a freqbox, and works just like it should! i put a cooler knob on the tuning pot, but the original purple one will ship with it!"
