DIY Sequencers and a Minimoog Music

YouTube via nathanielscott
"I am trying to figure out a good ways to use my two DIY eight step sequencers and a multi-frequency clock in conjunction with a good synth (like the minimoog used in this video) to make musical real-time music. This session was OK but I would like to develop a system of switching between sequencers to vary the patterns even more than I do in this vid. BTW, if you don't like the music at least fast forward to 7:39 and listen to the fat patch I dial in at the end.

I would like to once again thank the Reuseum in Boise for providing the parts for the sequencers!"

Kurzweil K250 Complete Sound Library

via this auction via gpoltrock in the comments of this post

"complete set of original disks for the famous, groundbreaking Kurzweil K250 keyboard as used by Stevie Wonder, Paul Schaffer, Kenny Rogers and others. There are 12 boxes of 10 disks each. 120 disks that include a great variety of sounds: piano, guitar, choir, drums, bells, harpsichord, ethnic, sound effects and more. Eleven of the boxes include documentation on the sounds and install process.

Of course, you have to have a Kurzweil K250 of RMX to use these and I offer these disks not really expecting much interest as the K250 sold for around $11,000 in the early 80s. 4000 were manufactured and there are probably few around in working order. Not being familiar with the instrument’s operation, I wonder if an old Macintosh computer is needed, too. The documentation states:

'The sound library is a growing collection of Kurzweil sounds on Macintosh disks accessible to you for playing in your K250 or RMX through QLS and the sound modeling program.'

The QLS might be a faster sound loading system for the 250... using the Mac instead of the floppy on the keyboard. It then lists the procedure on how to load a Kurzweil sound library disk using QLS. (Quick Load System)."

"In the first enclosure there are two 4770 Watt Block power modules for 8 and 18 VDC, there is a 4740 Envelope Generator, a 4710 Balanced Modulator, a 2720-12 Inverter Buffer and a 2720-11 Envelope Follower.

In the second enclosure there is a 4771 Regulated Power complex power generator with variable voltages and polarities (rare), a 4730 Voltage Controlled Filter, a 4711 Four Into Two Mixer, a 4761 Wing power block, a 4720 Voltage Controlled Oscillator, two 4710 Balanced Modulators and a 4750 Control Oscillator Noise Generator.

There is included also the May 1973 Radio-Electronics article by John Simington (PAiA founder and recently unfortunately passed) titled Build A Modular Electronic Synthesizer wich provides wonderful background and support infos for the line of PAiA synth modules.

Also included are original copies of the documents for the 2720-1 Voltage Controlled Amplifier, 2720-2A Voltage Controlled Oscillator, 2720-3B Voltage Controlled Filter (Band-Pass), 2720-3L Voltage Controlled Filter (Low-Pass), 2720-4 Function Generator, 2720-5 Control Oscilator / Noise Source, 2720-7 Power Supply, 2720-8 Keyboard/Case ( and the assembly diagrams, the 2720-11 Envelope Follower/Trigger, 2720-12 InverterBuffer, and 2720-14 Sine Converter / Pulse Width Modulator. These manuals provide a great amount of context for the 4700 modules and included schematics are basic to the functions they describe. There is also a wealth of information out on the net as you'd expect detailing the internals and functions of these PAiA modules. Check out http://www.synthdiy.com/files/2008/4700ug.pdf which is a User Guide for the 4700/S synth system.

These hip PAiA pieces have come into their own recently as Doepfer, Moog, etc, modules have skyrocketed in price and the vintage analog synth community recognized in the PAiA modules the value engineering and forward thinking design John Simington employed when he created this line of analog treaures.

There are a number of great articles about this fine (very underrated, known as "Poor Man''s Buchla" in some hip synth circles) series of vintge synth modules. One article is http://www.johnnypumphandle.com/johnny/Paia/paia.htm, but the most comprehensive is the legendary http://www.musicofplexus.com/paia4700/. In this extensive photo journal essay one can see the scope and depth of the capabilities of these modules when properly handled and with only quite modest upgrades made (High quality caps, ten turn pots on teh VCOs, etc)"
