This is an ancient telecommunications switching circuit originally used for something called Single Side Band Modulation. Basically a way to put a bunch of lines within limited bandwidth... Harold Bode (and perhaps others) reclaimed this technology for artistic purposes in the early 1960's, and Bob Moog (in collaboration with Bode) incorporated it into his Modular Synthesizer Systems in the 70's. By then they were calling it a "Ring Modulator" and the circuit had been signifigantly changed.
The modDemod features the original circuit, bare as can be, times 2 so that your audio source material may be "MODDED" and then "DEMODDED." This is exactly how the circuit was originally used... a telecommunication would be modulated, at which point it would be fairly unintelligable, and then on the receiveing end it would be demodulated. As you can imagine, some cool distortions happen on account of the inadequacies of this technology.
I hyper-matched over 350 diodes to get the sets needed to complete this LIMITED run of 20 pieces. Nontheless, there is still CARRIER bleed.
The front panel art work is a tribute to the origins of this wonderful circuit, executed with etched copper, gold plating and white ink on a flat black PCB.
This module is 4HP wide and consumes NO current. The price is $126. Now Available."

The original performance was continuous, but I had to edit it down to three sections to get around YouTube's 10-minute limit and some camera recording glitches. It's camera audio only, so not the best quality, but otherwise it's a reasonable document of the performance that night. I hope you enjoy it."

Featuring a brief look at the kit that is ready to use, though many more circuits to feature in the future. Again many thanks to the mysterious Van man for the use (and abuse) of his treasured gear. This is the precursor to more vids that will feature an in-depth look at techno and it's hardware. Korg Moog Roland Yamaha and Crumar synths are shown, enjoy the images, while we enjoy the hardware."

YouTube via spmaspma "Lemur controlling Ableton Live using OSC. A custom VST provides the timing information and handles the communication to/from Live as well as to/from Lemur.
Simultaneously running 2 instances of Lucifer VST, modified builds to be controlled entirely via OSC.
The result = DJ setup with no need for a computer screen, and a lot of things you can't even do with Ableton Live + mouse."
