"this is a sequencer i programmed in max using the lemur as a control interface. it sends midi info to whatever program you use. i also forgot to mention that each track can have independent timings, so varitions can span longer than just 1 bar of music."

Neuromixer AVdrum

"AVdrum is an audio video step sequencer and drum machine. You have the ability to switch audio or video of a movie clip On/ Off in realtime to compose AV sequences. This truly innovative software takes the concept of step sequencing to the next level.

You may trigger AV clips on AVdrum via computer keyboard or a MIDI controller like a drum machine. Using MIDI clock, it will sync to a master music hardware or software device."

"Altair-231 - is a monophonic 3-osc power synthesizer, mega rare unit, military sound, unique design, best of soviet-era quality synth, filters better than classic Moog synths. Produced by Estradin, millitary radio plant in Zhitomir, USSR in 1985. My machine was all time in not smoking studio. All original parts included, such as: original transport case and external pedal for volume control.
Synth has 4-oct keyboard (F-C) with velocity (sensitivity assign to vibrato effect). For live performance there is a wheel which provides pitch shift.
Synthesizer is based on 3 VCO (any can work as the modulator), 1 VCF (lowpass 24dB/oct) with ADSR, 1 VCA, 3 LFO, noise generator (white/pink), portamento. Consist of 5 main sections - MODULATION, OSC'S, MIXER, FILTER and AMP (called Contour)."

Emu Systems Modular Synth Technical Catalog 1980

images via this auction

"The Emu Systems 1980 Technical catalog. 81/2" x 11", about half an inch thick. Pages aren't numbered, so I don't know how many there are. Extremely detailed descriptions of every module of the Emu Synthesizer System, as well as a section devoted to the $60,000 Audity polyphonic synth (only one was ever made). I have no idea why this book was in my garage for over twenty years, but I found it while cleaning it out. The book has some age from mildew on the right hand edge, but all pages are clean and legible. Fascinating view of an extremely rare and high quality modular synth."

Update via the comments:
"A 1978 version of this is online at: emulatorarchive. Along with a lot of other E-mu documentation."

Alesis Andromeda A6

"Real Analog Powerhouse Andromeda’s fully analog signal path is controlled by a high-speed Motorola Coldfire microprocessor, offering 16-voice polyphony with 16-part multitimbral capability. Andromeda features two analog oscillators per voice, with standard waveforms (available simultaneously), suboscillators, hard and soft sync, and more. It provides two analog filters per voice: these 2-pole (multimode) and 4-pole (lowpass) resonating filters are classically-derived designs, and offer you an astounding range of sonic variability. Andromeda also provides external audio inputs that allow you to route any signal through its filters. Andromeda has three LFOs, each with six waveforms and many powerful features. It also has three 7-stage, 3-level envelopes capable of functions never before found in any analog synthesizer. An extensive mod matrix offers you an enormous freedom in configuring Andromeda’s sonic firepower, adding to its monstrous capabilities. In-Depth Control of Your Sound Andromeda’s 61-note synth-weighted keypad features velocity and aftertouch sensitivity, and its ribbon controlled offers multiple, assignable functions. A distinctive, futuristic front panel features 72 knobs and 114 buttons (the majority are single function), optimally arranged for rapid-fire tweaking and in-depth experimentation. Andromeda’s large, backlit LCD display provides real-world values of parameters (time, frequency, BPM, etc.) and high-resolution graphics. No other synth has ever offered such a sophisticated, informative control panel for creating analog pyrotechnics. Extensive features In addition to its real analog synth engine and hands-on interface, Andromeda provides a wide range of performance features, including multiple keyboard modes, portamento with nine slopes, and legato functions. For added grins, Andromeda provides a built-in arpeggiator and analog-style sequencer with MIDI sync, high quality digital effects Z(reverb, chorus, echo and more), and a nasty little analog distortion circuit. Internal program memory features 256 preset and 128 user-defined programs. Andromeda also offers a PCMCIA-format memory card slot for additional programs and mixes.
