Re: Need help with transistor match

Some thoughts: If I understand the circuit correctly, Q9 and Q11 just form a current source for the kbd resistor string. The result should be 8.33 mA. If I am right, you just have to ensure to provide 8.33 mA. This can be done by any current > 8.33 mA and an addtional trim. So I am not sure that mat...

Re: Individual Modules

I understand that. I was fascinated by Moog modulars since I was a child. The music of my heroes, the technical fascination of the "wall of knobs" I saw on LP covers and CD booklets made me swear that some day I will be owner of modular systems. But as I always wanted to look behind the cu...

Re: Individual Modules

Hello *, really, this is ridiculous. If Moog doesn't want to sell / deliver modules, others can do. What do people collect? Musical instruments or brands? Logos? "Passed" sticker or stamps of Moog? Really, I've seen an ebay auction where a 995 attenuator was offered for a starting price of...

Cool sound! A nice track, and I like the idea how you made the video.

Re: Building a synth ?.

I did. I built two modular systems over the years, a Formant and a Moog System 55 clone: current20080501.jpg current_20201222.jpg There are tons of schematics and forums available on the web, YouTube tutorials etc. Examples: https://sdiy.info/wiki/Online_resources http://www.muffwiggler.com/ https:/...

Moog 925 VC Reverb

Hello everybody,

does anybody know details about this custom module? Schematics anybody? Or at least which technology was used for this, e. g. BBD (PT2399, MN3207, TDA1022 or similar) or was it a controller for a spring reverb?

Re: Building a preset box

Cool reverb :)

May I ask another question? Did Bob keep the CA3019 based expo solution of the 901A when he transferred this to the 901B oscillator or did he change this to something like the heated transistor array solution like in the Mini then?

Re: Building a preset box

If I could I would post photos of my progress but as I noted earlier, this forum doesn't allow it. I know. If you mail me some photos with some comments I can put it on my web site and post the link. Unfortunately I can't share and schematics as I was given them in confidence. :!: Ok, but are they ...

Re: Building a preset box

How does it work? A selectable group of CVs connected to modules, especially like sequential switches etc.?

Re: Moog Model 10 and S-Trig

Hm, the question is, what does "negative polarity" mean. If the SQ 1 provides a constant voltage, let's say +5V dc, and the event lowers it to 0V / GND, it should work wth S-Trig devices. If the constant voltage is 0V and the negative polarity event lowers it to let's say -5V dc, it won't ...

Re: Moog Model 10 and S-Trig

Well, S-Trig just means that a constant voltage is shortened to ground to raise an event. Most sequencers provide V-Trigs (Voltage) where a voltage is set to raise an event. So the SQ-1 must be configured to provide S-Trigs, or a conversion has to be done. There are adapters which do so.
