octave transpose / potentiometer durability question

Post by midilifestyle » Wed Dec 10, 2014 2:49 am

So I'm away from my voyager for nine months while I'm in Mexico, and I got a cheap synth (mininova) to satisfy my daily synth therapy needs.

I got it after being blown away by Dorian Concept's youtube videos from years ago, and his technique of flipping through the octave transpose buttons with his left hand (while also modulating pitch and mod wheels with his left hand), and playing with his right. I'm getting really good at jumping around with octave buttons, and I want to translate this technique to the Voyager when I get home.

The problem is, the octave transpose buttons are in the most awkward spot if you want to make them a full-time set of real time controls.

For solutions, I was wondering if I could use the octave knob on oscillator one to do a similar thing (assuming I limit myself to one oscillator for the transposition). My question is: would wrenching on the octave knob constantly while playing damage the pot? I know the filter knob is built to withstand constant fiddling, but the osc octave knob isn't a continuous pot like that.

Will I wreck the potentiometer on my voyager?

Alternatively: if anyone could provide a workaround to assign octave transposition to some other control on the Voyager's faceplate, or can think of any other custom solutions, I'd be endebted to you.

The octave selector in the oscillators section is actually a rotary mechanical switch, not a potentiometer. It is of high quality and durability (industrial grade) and should endure thousands of flipping through octaves.

They're plenty rugged. Zero problems on my Voyager since 2003.

One of the issues you will find by using the Transpose knob to change octaves, is that you're only changing one oscillator at a time. Also, the filter may be set to track the keyboard is not being transposed at the same time, so the overall effect is different than playing in a different octave.

Hello!

Global octave transposition is done simply by pressing the edit button twice and using the up and down cursor
keys to jump octaves. If you must use the rotary octave switch to jump octaves for more than one oscillator, you could pot map the octave switch from oscillator 1 to octave function for oscillator 2, and it should control both, but I'm not sure if this works with the switch, so you'll have to verify this yourself.

Regards,

I know, as I said above: "The problem is, the octave transpose buttons are in the most awkward spot if you want to make them a full-time set of real time controls. "

I was thinking about the possibility of getting my voyager modified to install hard wired octave buttons near the pitch and the mod wheel. Does anyone know how hard this would be to have done? Bonus points if you know a synth tech in the Chicago area that could do the surgery.
