"These synths have to be one of the best looking synths ever, and they sound good also, with a lot of hands on control. I think the main complaint people had/have with the OB-12 was that it didn't sound like an original, analog Oberheim. I don't have experience with an original analog Oberheim but I think the OB-12 sounds great and is a lot of fun to play with. History seems to be treating this synthesizer kindly and the prices for them have been creeping up for years."

"If you are looking at this, you probably already know all about the MG-1. You will also notice that with the wood panels it is probably also one of the sexiest that you have ever seen!

This unit is in 100% working condition. Every key, knob, and switch is working. The black foam has been removed, and the sliding pots have been cleaned out as well.

This synth was recommend to me by Chris Walla from Death Cab for Cutie when I asked him how he got those nice vintage synth sounds on the Kintsugi album (specifically on the song Black Sun). This synth is amazing! If you like thick 3D Moog sounds, you will love this synth. The filters are definitely all Moog!"

Moog 904-A Eurorack clone by controlvoltage.org DEMO

Published on Aug 2, 2016 Roberto Raineri-Seith

"A 'quick and dirty' demo of the controlvoltage.org Moog 904-A clone for Eurorack that can be ordered as DIY-project on my website controlvoltage.org (production files only).

The filter is fed with a single square waveform from a Mos-Lab 921-B VCO.

Various settings, initially without, later with frequency control from the same envelope used on the VCA. No attenuators used. Delay and reverb added.

Final note: the module was only roughly calibrated and not all transistors were matched, so for purist there is some improvement margin left ;-)"

See this post from 2012 on the controlvoltage.org 904.A, and this post for another video.

..about modular classics (1) - HerrSchneider from HerrSchneider on Vimeo.

"Nowadays some of the younger potential customers are expecting something like a demo button on their new modulars not willing to learn basic technical scills from adsr down to sample&hold. Making a patch on a classical modular system (like this one from Analogue Systems) could lead you to classical synth sounds with spherical athmos quite easy, but.. I tried to not follow this, what looks easy with so many modules in front of me. To let you understand what i did, you can find some explanations of the patch at the end of the video, I hope it is not too boring.

Please listen to the sounds with a headphone or speakers, you will hear the quality of the filters, the bass is indeed very simple. The RS-370 is able to do lots more, but this will need an extra video .. hopefully soon."
