Buchla 100 analog modular music synthesizer

via this auction

"very rare Buchla 100 analog music synthesizer from the 1970 time frame. The analog sound is very rich and organic as a result of Don Buchla's innovative electronic circuit design that is largely based on discrete transistor circuitry. This raw organic sound quality when combined with the unusual control techniques is fundamental to the so called San Francisco West coast sound... This cabinet was part of a larger Buchla 100 system... Control voltages sources include a touch controlled voltage source, a 16 stage 3 output sequencer, a dual attack generator, envelope follower and timing source. External audio processing includes a dual microphone preamplifer, dual spring reverb and a very rare frequency shifter. Internal sound sources include sin, saw and squarewave oscillators and a white noise generator. The system includes several filters including the very rare and desirable 191 sharp cutoff filter.

Top row - 170 dual microphone preamplifier, 130 envelope detector, 185 frequency shifter, 190 dual reverb, 175 equalizer
Second row - 158 dual sine-sawtooth generator, 160 white noise generator, 106 six channel mixer, 191 sharp cutoff filter
Third row - 180 dual attack generator, 110 dual voltage controlled gate, 106 six channel mixer, 194 bandpass filter, 144 square wave generator
Fourth row - 140 timing pulse generator, 146 sequential voltage source
Fifth row - 112 touch controlled voltage source"

NOTE: the auction is for the knobs only, not the module: "(2) Buchla Synth Module Knobs. The knobs you are bidding on are the pointer knob and the small round one pictured in the photo. These knobs are N.O.S. and look like they left the factory yesterday. Please don't email me about the 191, its now living a happy life in a e-music studio in NY, NY. This sale will be final with no return."

"SYNTH WAS PURCHASED ABOUT 5 YEARS AGO, IT WAS PURCHASED USED. IT HAS BEEN MAINTAINED IN MY STUDIO ALL THE TIME, IT HAS SEEN LITTLE USE UNDER MY OWNERSHIP AND I THINK IT’S TIME SOMEBODY ELSE HAVE FUN WITH THIS ONE AND I NEED THE MONEY AS WELL. SYNTH COMES WITH A BUCHLA MANUAL, LOTS OF PATCH CORDS. SYNTH WORKS FINE BUT IT MIGHT NEED CALIBRATING BY NOW.

MACHINE WAS KEPT IN A DUST AND SMOKE FREE ENVIROMENT.

Buchla synthesizers are the classic creations of Don Buchla, a circuit designer who produced synthesizers when they truly were analog beasts. Buchla started making his first synthesizers on America's west coast for the purpose of simplifying the tedious process of creating "Musique Concrete". Musique Concrete can be thought of as the predecessor to Electronic Music. It was a form of music in which recordings of various sounds on tape were cut, spliced, distorted, and manipulated in various ways before being spliced back together into something that should sound like music...almost like super old-school sampling & sequencing! This concept was the driving force behind almost every Buchla synthesizer made - an electronic device that can create some basic sound, manipulate it, tune it freely, and sequence it into organized sound, hopefully something musical! With that in mind, Buchla synthesizers were among the first to use indivudally tuneable keys for limitless micro-tuning possibilities, analog sequencers, and complex waveforms other than basic sine, sawtooth, and square waves.
