"Korg Poly800 Mark 1 Synthesizer

The "FM800" mod : Source switch, FM Modulation depth knob
Audio Input: Level Knob, Path switch, Filter CV socket.
Hawk800 and Atomahawk boards both installed with all these extra features:

full MIDI spec whereas the original Poly800 had none.
Loads of new parameters: 4 LFOs, many LFO shapes, masses of modulation routings possible, free running or not.
Flash memory so no internal battery required.
7 sequencer memories (originally 1).
MIDI velocity sensitivity.
Moog Slayer and FM800 mods also included so they can be MIDI controlled.
Portamento Mono mode.
4 patch banks
and much much more.
All these mods turn the friendly Poly800 into an extremely versatile and deep synthesizer.

The synth itself is in good condition with the usual minor scratches of something this age. Supplied also is a printed Poly800 manual (not original) and Hawk800 manual, plus PSU."

Composition in Electronic Components: Experiment I

Uploaded by DeRaafMedia on Sep 17, 2011

"A musical composition. A composition maybe made from the point of view of a computer or other electronic device.

Do computers like us? Do they like the interaction we have with them.

We don't know. All we know is that we most probably slow them down with our presence, almost grind them to a hold.

There is a huge difference in the computational abilities between us. If we want to compute something, we need to go sit behind the keyboard and mouse, that slows down the computer. It needs to listen. Even if there where fast way's to interact, like speech or even brainwaves, it would slow the computer down.

This little experimental musical piece explores this. We got a little micro controller that happily sends it's serial communication to his companion, a little emulated SID chip. This serial communication consist of random registry entries so the SID can generate some random sounds.

But there is a opportunity for a human to interact with this micro controller, a PIR motion detector. If there is any movement registered this electronic circuit needs to slow it's activity down (by a factor of 10).
