"Reprogramming the 1st preset-piano on the Ensoniq ESQ-1 into something more appropriate. The ESQ-1 is certainly on of the easiest synths to program despite its' lack of dedicated knobs."

Predictive Music Synthesizer - Plays all possible digital sounds without a computer

YouTube via VironCybernet
"Unlike the "Pandora's Box" Synthesizer, which is more melodious but exponentially redundant, this axiomatically rather than theoretically generates all binary strings at a break-even point. Starting at zero and counting until it reaches a state that would fill all of a computer's memory with bits that are all ones, it is guaranteed to generate all possible binary strings in order, including programs and data, but here applied only to the digital sound of all of those strings. It sequentially outputs each digit of Champernowne's Constant using logic. Discovered in 1927 by David Champernowne and Alan Turing, the CC is known to contain all possible digital data and is obviously prior art to all possible digital sounds. Which means, no new digital sound was ever invented nor recorded nor ever will be. Although this demo doesn't sound very good, math is known which has actually been used to find music by calculating and playing a specific series of digits of this number. The number's intrinsic sound has musical characteristics that are not easy to hear in this video, with rhythm more prominent than melody. A small knob is turned to adjust the very high sampling rate, the prominent buzzing sound is actually the rate at which this circuit is playing unique sounds (as each string of digits, which is each a unique whole number counted in order) in fast-forward. I think most people would agree that this demonstration does not play any good music in this video, but nonetheless it is a matter of fact that the process in progress does generate all possible digital music by definition. Inspired by the millenium music copyright controversy, this method of generating sound seems turn the idea of digital copyrights into complete nonsense, since it needs no memory nor copies to extract all possible data from a number already known to contain the entire infinite set of it."

Computer Motherboard Fractal with Sound

YouTube via VironCybernet. see Viron Cybernet's YouTube channel for more.
"Hundreds of fractals have been discovered and tested for musical qualities. This one resembles an infinite plane of circuit board and in the process of displaying it, each pixel plotted is also output to the speaker at the same time. This one was discovered and labeled XAX(23,13). Another, XAA(23,13) differs by only one logical function operator and looks like an alien hieroglyphic font. These were discovered, ot designed. Any resemblance of the fractal to an electronic circuit board is entirely unexpected."

Gingerbread Man Fractal with Sound

"Experiment. The gingerbread man fractal is demonstrated both visually and with audio output. The sound of this fractal obviously lacks any pleasant musical qualities. Hundreds of fractals have been discovered and tested for musical characteristics like this."

akai ewi with circuit bent speak and math cv midi synth

YouTube via spunkytoofers

"the akai ewi 3000 uses control voltages and has an all analog signal path with it's dedicated module. in this example the ewi 3000m module sends midi to the speak and math as well as control voltages brought to the surface of the 3000m on banana jacks. the banana jacks are sent to a cv control box which is essentially a foot switch box with various logic functions and and open ended patchable interface. ewi controls overall pitch of the speak and math based on pitch fingering cv output in conjunction with octave key cv output. the midi is a retrofit kit available by highly liquid and accesses the speak and math's rom by triggering key commands. this modification gives the user a wealth of circuit bent sounds accessed by midi note triggering. the speak and math's output is sent back to the 3000m's analog amplifiers and filters via breath control on the ewi. there are various note sustain loops and a photo theremin available on the surface of the speak and math via stomp switches. the stomp switches activate leds to indicate on/off. also a big knob with a rubber boot that can be played with the feet.. this is my first run through of my speak and math cv midi synth"

polycontrol-robot44 Analog Synth Pop

YouTube via MASCHINENMUSIKREC
"POLYCONTROL released their debut CD " Symphony in C/V " in 2006. With their charming 80ties Synth Pop influenced style they immediately got a very good response from their auditors.
Using a lot of old analogue synthesizers from the 70ties and 80ties, combined with modern software equipment, POLYCONTROL create a sound that is warm and harmonic, retro and modern at the same time.
This particular song was created with Korg MS 20 and Sequential Prophet One, sequenced with the ORION software by Synapse Audio."
