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

From: ach_gott@...

I'm actually really curious about this from the opposite perspective. I'd like to be able to do pseudo-additive synthesis using a small collection of oscillators and all of mine are callibrated for 1v/Oct. I'd like to be able to have a separate amplitude envelope for, say, partials that are multiples of the fourth harmonic. But at this point, I can't take the log of 4x, where x is the fundamental to get the right calculation (I think I have that right, I'm talking off the top of my head walking home). Psim would be the key, I suppose, but that won't ever happen. The only way I can think of is multiple midi channels off the same gate with each such harmonic scored. Not sure how to handle this for live performance, which is what I want.

Cheers,

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?
