Re: How do you know if your Voyager has the slew rate mod?

That's a good question. I don't think you could verify unless you opened it up & checked the IC's & circuit. Moog did revisions over the years that covered some of the same things, but not all, as the slew rate mod. The factory & authorized repair centers did the mod AFAIK. Usually a sel...

Re: Model 10 Calibration

Or maybe a gut shot would reveal which IC's they used?

Re: RA Minimoog

I think "synthpro" on youtube has a video with them all lined up & he talks about them. I just looked but couldn't find it: he restores synths & has a lot of interesting videos, worth checking out.

Re: Model 10 Calibration

Good info, thx!

Do we know what Moog did to improve tuning on the rev2 RI model 10?

Re: Model 10 Calibration

Good info: is that what the Voyager uses?

Maybe I'll build a modular cab that doubles as a beer fridge :lol:

Re: Multi-expression controller one moogerfooger

I haven't tried MF's CV OUT yet in the manual says it's independent ("The amplitude of the ENV OUT control signal is independent of the setting of the AMOUNT control or pedal."). If I manage to work out a good setting I will post or if anyone else has any idea how best to use it let me kn...

Re: Analog Delay VS Digital Delay

What would you consider an affordable analog delay that’s in stereo? I don't think "affordable" and "analog stereo delay" belong in the same sentence :D You could buy 2 mono analog delays though, and use them together. Behringer VD400's are cheap. I have two I plan to string tog...

Re: Model 10 Calibration

I wonder if there is a way to build a temperature box around that part of the circuit? Seal it off & add some kind of temp sensor that would keep it stable

Re: 1976 Minimoog Unstable Oscillator 1

Depending on how audible the problem is, you could try spraying cold compressed air on various parts to identify the troublemaker?

If it is related to temperature

Re: Voyager wave shape modulation

At some point I want to add CV ins for each osc wave shape. Too many other repair projects on the go though, and trying to write music too. No time..

Re: Voyager wave shape modulation

Wow Till, that's great information, thanks for posting! Too bad the LFO is not usable as a pot mapping source: I think I ran into this before: thinking the concept of "pot mapping" was "source mapping" but it's not. if you have a VX351 breakout box you can get the LFO CV & pa...
