Subject: [motm] 1v/hz vs. 1v/oct

Hey friends,
 
 I just acquired a metasonix tm-3 oscillator, which takes a CV input 
 of 1v/hz (as opposed to 1v/oct) ... I got the one with MIDI, so I can 
 theoretically drive it alongside my other 1v/oct equipment on two 
 separate midi channels that output the same information, but that's 
 rather inelegant, and what if I want to drive it from a non-MIDI CV 
 source (LFO, envelope, sequencer, etc) or add slew to it, etc etc?
 
 Is there a handy conversion module that goes back and forth between 
 the two anywhere? or a PCB/schematic of one I could build? I don't 
 know a lot about it, but seems like it would be pretty useful and not 
 *too* tough, yeah?
