Moog Minimoog with Kenton MIDI

images via this auction
"serial number #11233, made in 1979. This Minimoog has been bought new in 1979 by Derek Holt from historical Climax Blue Band, who always kept it until few weeks ago... The Kenton MIDI interface installed was, in the 90s, one of the most complete and expensive midi conversion kit for the Minimoog. I checked it connecting
the synth to my Logic Pro 8 software and it responds precisely, so that I am sure that the interface is in perfect state!

Anyone know what the holes on the back are for?

"You can use one MPG-80 to program several modules as long as they are in the same MIDI chain - just change the MIDI channel on the MPG for the unit you wish to program."

Synthesizer Basics by Keyboard Magazine

via this auction
"COPYRIGHT 1984
In this easy to read reference, Brent Hurtig takes you through the basic concepts and parts of the basic monophonic analogue synths of the 60's and 70's. This book is a wonderful introductory guide into the world of eletronic music and its origins. Just after reading the first few chapters out of a copy I got from the local library, I can now tell what makes an analogue synth tick. It also gives you a look at MIDI basic principles and the invention of digital synthesis.This book has sparked my imagination about electronic music and made me want to get out there and make some noise. My only negative comment is that it's a little out of date, but if your looking for information on modular synthesis, Moogs or analogue basics, this is the place."

Mankato Filter

via this auction
"The Mankato Filter is a four-pole lowpass filter with positive and negative outputs at every pole, giving you slopes of 6 dB/oct, 12 dB/oct, 18 dB/oct, and 24 dB/oct simultaneously. the negative slope outputs allow you to use the Mankato as a quadrature sine oscillator with 8 available phases. the Mankato will self-resonate from subaudio to superaudio, and responds to one volt per octave through its unattenuated control inputs. the signal inputs are DC coupled, which allows you to use the Mankato as a voltage-controlled slew limiter.

An audio demonstration of the filter can be found here. it is a 5-track composition using the Mankato for something on every track, and it is the only filter used in the piece.

it is powered from Synthesizers.com power supplies and fits into Synthesizers.com rack frames and cabinets. it also physically fits into Moog modular cabinets but a Synthesizers.com power supply will be needed."

THE JOHN BOWEN CHRONICLES

on SONIC CORE
"Starting later this month, we will run the John Bowen Chronicles on our Website, with new installments every few weeks, leading up to the release of the SOLARIS synthesizer. We hope you find it a fun and fascinating look into the synthesizer design process, and perhaps inspire some of you to take your own adventure exploring and creating with the SCOPE design software."

The History of Uncertainty

via Reed:
"A panoply of not-quite-randomness from 1970 to the present. On the left is the Model 265 with its mesmerizing lamps and undisputibly the best sounding noise generator of the series. At center is the pinnacle of late-1970's Buchla, the model 266, a 6-in-one box of wholesome goodness with some extra not-so-uncertain features as a duophonic sample & hold and a voltage-controlled integrator (glide). On the right is the 266e from 2004. Although it looks a lot like its predecessor, the e-series uncertainty module is really its own animal. It does equal divisions of the voltage sweep in the "quantized" section. The original 266 does some sort of wacky binary equation that yields irregular but western-friendly relationships. For example, if you set an oscillator's mod range to an octave, setting the range to 4 steps will give you a major second, perfect fifth, dominant 7th and octave. If you do the same setting from the 266e "quantized" section, you'll get a diminished arpeggio (4 equal divisions). And then there are the stored random voltages....the original 266 has a "time correlation" control, which is kind of a hat-tip to the last-note "correlation" control on the 265. The 266e gives you vc skew, which sort of lets you approximate a s&h sometimes if you've had enough scotch. And by that time it's a good idea just to call it a night."
