Moog Music Forum

Moog has updated their already excellent Model 15 app, and along with substantial updates to the Audiobus capabilities, Midi and the built-in recorder they have included three new collections of presets available as IAPs, including a collection I designed specifically for this app called Mercurial S...

I just got a Sub 37 and am slowly picking my way through the (many) various modulation possibilities. One thing that I haven't been able to accomplish so far is the ability to use the actual oscillator output to mododulate the other oscillator frequency input (cross mod) or use an oscillator output ...

I've owned a bigger 55 system for a long time, but the limitations in regards to oscillators vs LFO's are still pretty much the same. The 921b can be used as an LFO, but all 921b oscillators track the 921a, so you can't make the other 921b track the keyboard without the 921b LFO speeding up and slow...

These were made by CTS. I think I remember seeing them on some tube amplifiers as well being used as 100 ohm hum balance trimmers for the tube filament circuits. I'm not sure what the original model number of this trimmer was. CTS made a 115 series that looked sort of like these...I'm not sure if th...

Those are the venerable CTS 201 series trimmers, I believe.... http://www.ctscorp.com/wp-content/uploads/2015/11/Series-201.pdf They're probably still available if you look hard enough. As an official kinda old guy, I remember these fondly, and used them in many homebrew synth projects. I like them ...

Here's a link to a folder with some various patches from my library.
Be sure to select the descriptions button in the preset page to see info about each patch with occasional construction hints, playing tips, etc.

Cheers!

Tomita was one of my early synth heroes. While I absolutely loved his incredible musicality with the Moog, I appreciated even more his indelible sense of humor when realizing the various pieces of music he tackled over the years. He made the Moog chirp like tiny chicks, made it sing nonsensical and ...

Unhappy, unhappy day.

He was a HUGE influence to me, and so many others.

Safe journey, Keith.

I've just published some musings on the 905 in my blog.
Synchronicity!

The reason I'm asking is because while looking at the current photos on Rezin's site, I noticed that there doesn't seem to be any connection at all to pin 3 (-6V) that I can see in this picture... https://www.flickr.com/photos/cryptorose/24921427145/ If you enlarge the area at the connector, you can...

Hi Rezin! I still have a few questions about the 905 reverb module, which I think got lost on a few previous pages. Your help would be greatly appreciated! 1) At the bottom left quadrant, there's a 10uf blue cap, a 220 ohm resistor, then a resistor that I think is a 33k, but is hidden from view by t...

Thanks for the great pictures, Tom! So, what's your 100k trimmer hooked to? The 100k on the production unit is hooked between the output and ground...adjusting it low enough would eventually lower the output, but wouldn't really affect the noise. Yours might be the Q2/Q3 feedback? Still hoping for a...

Back when Moog started making these, there weren't a lot of choices for springs. I'm assuming that the springs available back then were all about the same as the units being used in most guitar amps. The typical Fender amp springs back then were usually an 8 ohm input impedance, and a 2.5k ohm outpu...

Yeah, me too!
I used the original link to his flicker account, listed in an earlier post, and there they were!

Thanks a million! These newer pictures are a big help, and I really appreciate you taking the time to help us here at the forum! A couple more questions, if I may.... 1) At the bottom left quadrant, there's a 10uf blue cap, a 220 ohm resistor, then a resistor that I think is a 33k, but is hidden fro...
