Re: Animoog

Not a silly question at all - it's a very good question actually. As ImNotDedYet has already explained, the Sub 37 and the Animoog app are very different animals. But to my ears, Animoog does sound distinctly 'Moogish' and is a lot of fun to experiment with. The Sub 37 is a brilliant and inspiration...

Re: Suggestions for modular stands?

It's a tricky question. Depends how you work and what you're personal preferences are. Personally I work mostly standing rather than sitting so I'd need it to be fairly high to operate comfortably. I'd aim for the centre of the panel to be just below eye level if the panel is vertical in the time-ho...

Re: Dirty sine wave from 901?

I built one of those from scratch - and it works like 'magic'... It's a great design. Simple, economical and yet so effective. Amazing what Bob & co. could manage to achieve with a handful of discrete transistors back in the day. Did you use the transistors as spec'd or just any general-purpose...

Re: Analog board of Old School: same as regular Voyager?

I have no idea, not having a schematic of the board. If it doesn't look like anything has ever been soldered in there and removed I really wouldn't worry about it. From the cap values they sound like bypass capacitors which may not have been needed in the VOS design. Why do you ask incidentally? Are...

Re: Dirty sine wave from 901?

On the 901 the sine is derived from the triangle wave which is in turn derived from the sawtooth wave. The triangle is formed by inverting/mirroring one half of the sawtooth wave cycle. From your scope trace, the triangle is not quite symmetrical - i.e. the circuit that inverts/mirrors the sawtooth ...

Re: Minimoog pitch wheel calibration

Yes it was designed that way, but it was a compromise. Personally I don't have a problem with it, but some players apparently do. On the Voyager Old School you can select a PB of either +/- 2 semitones, +/- 7 semitones, or +/- octave using a jumper on the left panel board. Not exactly convenient but...

Re: Analog board of Old School: same as regular Voyager?

Yes. It's the #11-404P same as all Voyagers.

Check the photo here of a VOS opened up and zoom in. You can clearly see the board number.

Re: Minimoog pitch wheel calibration

I think the normal bend range on the MM is around +/-7 semitones (a fifth). To reduce this you could try adding two trim pots either side of the 25K LIN pitch wheel pot, between and the CW end (3) and +10V, and the CCW end (1) an 0V. Try 5K or 10K trim pots to start with (I'd use for 10-turn ones fo...

Re: Religious

Wow! Glad you find the Mother so inspiring. I'd hold off on selling that guitar though. I'm a poor guitarist but I find that there's nothing quite like it for sitting on the couch and coming up with ideas. Balancing a keyboard on my knees just isn't the same!

Re: Mother 32 x 3 in Eurorack - Power Issues

It's not a show stopper, just an annoyance. The only thing is, I can see the problem getting worse as I fill out the rest of the case. Asked Doepfer support and their solution was to downgrade the PSU3 to the (discontinued) PSU2 which is an all linear design and not so sensitive to the initial inrus...

Re: Minimoog Model D Osc 3 Control switch defies expectation

Megavoice -- replacing ageing electrolytic caps in the power supply can only be a good thing. As others have noted above, replacing caps in the audio signal path can affect the the sound and character of the instrument so that's up to you. Personally, I replace ALL electrolytic caps and I've only ev...

Re: 911 extra capacitor

It's a de-bounce to the input of the transistor bistable pair Q13/Q14 - probably not required but if it's in the original schematic I'd prefer to include it.

Re: The Global Synthesizer Project

The advertising pitch makes it sound like it's 'modular' hardware (sample player) but I seriously doubt the logistics of that. It's most likely a software implementation (probably an App). That would have a greater market reach than hardware would and would make much more sense. It seems very intere...

Mother 32 x 3 in Eurorack - Power Issues

I have 3 Mother 32s in a Eurorack case powered by a Doepfer PSU3 (2A on +/- 12V and 4A on +5V). The Mothers only use the +12V supply and according to spec. consume 3 x 230mA = 690mA. Actually on my meter it shows 605mA but I expect it depends on what's going on in the Mothers at the time (e.g use of...

Your 901 sounds like a a couple of guys talking about 10 feet from a mic. Cool effect :wink:
