Roland CMU-800R

via this auction
"The following is from a Roland data sheet from 1983: **** The CMU-800R is a new dimension computer peripheral which allows free composing and arranging, as well as automatic performance. This unit features a host of functions, real musical instrument sound from its build-in sound source, and a wide variety of musical nuances such as slur, staccato, accent, and legato, plus an added function to control eight external synthesisers. Its is not an extention of a simple hobby computer as represented by conventional games. The CMU-800R is the very first unit to proclaim the arrival of a real computer age in the musical genre. Each computer is provided with a software package for easier programming and advanced editing functions. Now, music fans with no particular knowledge of computers or computer operators who cannot play a musical instrument can both compose and arrange at their option as well as enjoy automatic playback. **** The CMU-800R delivers its maximum performance with its separately available software package. With this software package, anybody will be able to handle the CMU-800R efficiently. The software package includes the CMU-800R

control function and edit function for music data preparation. The edit function allows you to do difficult types of screen editing on the CRT monitor connected to the computer. So, sequence editing and modification can be done in amazingly short time. **** Complete built-in sound source for a real music sound **** In addition to melody, bass and chord (4 notes), the CMU-800R has seven percussion instruments sounds, i.e. bass drum, snare drum, low tam, high tam, cymbal and open/closed hi-hats for rhythm patterns. All other sounds have decay and sustain (melody only) effects. In addition, each part can be level-mixed with a slider volume control, and playback tempo can be varied as you desire. The CMU-800R is a product of Roland DG, an electronic musical instrument manufacturer, and built to give a new dimension in sound creation. **** Expandibility, a more sophisticated music system **** The CMU-800R needs an amp and speaker to produce sound. In combination with an effect unit, mixer, tape deck or the like, a more complete sound is created. The CMU-800R is able to operate up to eight external synthesiers simultaneously with its CV & gate outputs. Clock In/Out permit synchronous performance with external rhythm machines and percusion synthesisers. The more-you-play-the more-fun-you-have CMU-800R is superbly expandible into a more sophisticated computer music systems."

Waldorf MiniWorks 4Pole Filter

via this auction

"Without doubt, no other synthesizer component has such a decisive effect on sound quality as does the filter. All of us at Waldorf, and of course the owners of Pulse's and Pulse Plus', know all about the exceptional qualities of our analog filters. We would obviously like all musicians to have the chance to access this quality component, so we simply implemented it as a separate module. The 4-pole is our four pole cascade filter, combined with incredibly fast envelopes and a stereophonic amplifier stage. You are free to apply this filter to any audio signal that you manage to patch into the device via a 1/4" jack. So if your favourite sampler or sample player lacks that special quality, you can give it a sonic boost via the 4-pole. You can even overdrive the audio input to get distorted signals, if you like. Cutoff Frequency, Resonance, Volume and Pan may be modulated by numerous modulation sources, eg. LFO, envelopes, MIDI or the built-in envelope follower.

Technical Features:
Waldorf 24 dB lowpass filter with variable resonance up to self-oscillation
40 programs, divided into 20 ROM presets and 20 user programs
24dB analogue low pass filter with resonance up to self-oscillation
Filter input can be overdriven
stereophonic VCA with real-time panning modulation
VCF ADSR envelope
VCA ADSR envelope
LFO (5 different waveforms; tri, sin, saw, pulse, sample&hold)
15 modulation sources
Envelope follower
4 edit knobs
1 gain knob
1 trigger level knob
5 buttons
Large 3 x 7 segment LED display
monophonic audio input

MOOG System 12 Manual from 1973

images via this auction. via Bill.
"Another obscure item from the Garage Archives. The Moog company was gracious enough to send me this manual in 1973 for me to learn more about modular synthesis. It's sixteen pages, 8 1/2" x 11", and gives a good general overview of patching the modules, and the basics of subtractive synthesis. It's interesting as a historical

piece, but would also be useful to anyone using the excellent Arturia Moog Modular V virtual synth."

the squarewave parade updates

Some updates from the squarewave parade: "its been a while, there has been a lot of new work in and out of the store in the past month or two. i have a few new things in there now and more on the way soon.

CONSTANT - analog VCO parasite

PARADE - 6 voice squarewave parasite

the CONTUSION - bent keyboard with a shiver parasite installed.

the PARADE - 6 voice squarewave oscillator - prototype

the SLOSH PARADE - 6 voice squarewave oscillator and low pass filter - prototype

Blast Fed Disaster Joystick - digital synth / noise generator
- samples and detailed explanations of everything can be found on their pages

over the next few weeks i'm going to try to release batches of the new SLOSH BOX - ST which is a stereo variable resonate low pass filter. a batch of the new MING-MING a dual ( stereo ) version of mingrod passive analog ring modulator / octave up. as well as some more PARASITES - the CONSTANT, PARADE, and possibly some others, and as soon as i can swing it a couple more brand new regular boxes with fantastic names.
sorry for holding off on releasing the new DOWNGRADE i want to be 100% happy with it before it leaves my hands. i hope to have the first batch available in a few weeks as well. also i saved over my page on accident and lost my write up. if by some odd chance you saved it could you please send over the text. it would save me a lot of time.

GETLOFI did a little interview with me regarding the parasites. it might answer some of your questions.

there now PARASITE wiring diagrams, manuals, and a couple walk through available -

i just signed up to be one of the sponsors of the Circuit Bending Challenge hosted by GETLOFI and Create Digital Music - the winner gets a PARADE ( 6 voice osc ) parasite and a hand full of stickers and buttons from me. Rodney from Tiger Claw Records is throwing in some CDs, a shirt and stickers. FutureKomp is putting in a stack of CDs and i’m sure there will be more great gifts from the others as well. so read the directions and clear your sunday schedule.

i posted some more schematics on the scheme page. there is the BFD, TLLYWCKR, MIMEO, and a basic res filter diagram

i started a little mailing list for people to post their latest experiment electronics escapades called TRY http://la-ac.com/mailman/listinfo/try_la-ac.com its quiet right now but as soon as you subscribe and start telling people what you are up to i'm sure it will get interesting.
- more soon"
