Korg MS-20 doing a disco beat

YouTube via zioguido
"My MS-20 is playing a disco beat by itself! This is an endless loop created by retriggering the notes using the MG pulse output.
The connections on the patch panel are as follows:

1) MG sqr out to TRIG IN (the jack I'm inserting and removing to start/stop playback)
2) WHITE NOISE to VCA IN
3) VCA OUT to ESP IN with low-cut and hi-cut filters all the way up
4) ESP band-pass out to EXT SIG. IN
The white noise fed into the ESP and then into the EXT.IN does the hi-hat, while the EG2 with a rapid decay does the bassdrum using the hi-pass filter and the EG1 with the delay time set to 1 does the octave jump on the bass. You can see the other settings in the video.

Watch your speakers! This is gonna be loud!"

Mondo Modular Episode 5

"Back-in-action after a short hiatus (note new studio set-up -- but more about that in an upcoming video), I'm finally making good on some of that Herb Deutsch footage I promised a few episodes back. I figured there was no better time to do this than around the time of what would have been his 74th birthday (May 23rd).

I'll post a couple of fun stories from Gershon Kingsley next time and then return to the familiar format (ie: my dorking around with my various knobs and patch cables).

Special thanks to the Grammy folks who recently gave some money to the Moog Foundation to try and get the various papers and prototypes in Bob's old work shed in some kind of order and will hopefully see to the future preservation of."

Build a Transistorized Theremin by Bob Moog

via this auction
"Increasingly hard to find, this nearly half-century-old issue of Electronics World contains a fascinating how-to on building that special effects staple of scores of classic sci-fi flicks, the theremin, by none other than electronic music pioneer Robert Moog. The feature article contains a complete schematic and parts list, as well as chassis layout and photos of the completed unit. There are even tips on how to play the ethereal instrument. You get the entire original 1961 magazine, not a couple photocopied pages like you find elsewhere on Ebay.

Also in this issue is a homebrew stereo balancer using 6FG6 magic eye tubes and a look at beam power tubes in VHF oscillators, plus an article on early computer logic circuits, both vacuum tube and transistor-based. Apart from some minor cover wear, the magazine is in excellent condition."

"This little beast is far from your average FM synthesizer. Not only is it an eight-Operator variant, as opposed to the six- and four-Operator FM of the DX/TX lines, but it also features a new technology called Formant Shaping Synthesis. Formants are the spectral patterns making up the sounds of human speech. This allows for the creation of vocal like timbres but can also be applied in many different ways to create incredibly unique sounds that you won't find on any other synths."

"Filter - Dynamic Resonant physically modeled 12/18/24dB/oct low/band/hi pass filter (AN1x type)

Effects - 15 (Reverb), 28 (Variation), 40 (Insertion), Equalizer

Memory - 1536 Voices, 512 Performances, 96 Formant Sequences

Plenty of software for Mac & PC"
