MOOG MODULAR SYNTHESIZER SERVICE MANUAL

via this auction
"This is a fresh copy of an original service manual from Moog Music that I purchased in 1978,It covers information on modules for:
System I , II, III, 12, 15, 35, 55,

It is 54 pages which contain:
1. Full Schematics for all Modules,
2. Alignment and Tracking Procedures,
3. Interconnection and Cabinet Wiring,
4. Transistor Matching.

With these schematics and some technical knowledge you can build your own $20,000 synthesizer,(I did)" Note the modular this person built pictured below.

"The most popular MOD was made by a qualified Sequential technician on this Pro One. You see it on the last picture. THERE IS NO DIRECT MODIFICATION MADE ON THE PRO ONE. IT is only a small circuit board that was added independently. It is an inverter, that inverts the polarity of the filter envelope. GREAT MOD! IT DOUBLES THE TYPES OF SOUNDS POSSIBLE ON THIS MACHINE" YOU CAN MODULATE ANYTHING (PW, FREQ, CUTOFF) WITH A NEGATIVE ADSR! SO GREAT! Just push the switch back down and you get a regular Pro One"

New England Digital Archive

"This page is devoted to information and projects about one of the most sophisticated synthesizers ever made, the New England Digital Synclavier, and its offspring, such as the rare Synclavier I, and its sucessors, such as the big 9600."

You will find sections on history, documentation, audio and video. Pictured here is the Synclavier I which consisted of the monitor and three cabinets in the background.

"What is your favorite piece of hardware?
Arp Odyssey. It sounds awesome and I've owned one for over 10 years and never gotten tired of it. I have two Odysseys, a Mark III, and a Mark I. The Mark I was a hand me down from my uncle that was broken. I ordered a 2 pole filter replacement from an online tech guy and soldered it in and then I did the Kenton CV/Gate/Filter mod as well. It works, but it still doesn't work perfectly. I'm still researching into how to fix it. The Mark III is the one I've had for 10 years. I haven't done any modifications. It works and sounds great."

"An experiment using the EQ bands on a Behringer UB1202 as four fixed-tone oscillators in a feedback loop, with a Bleep Labs Thingamagoop phototheremin and Tapco 4400 reverb as the input sources."
