"This device is amazing. The sonic potential is so vast that I doubt you could fully explore it in a lifetime. The circuitry may seem trite and simple but it is used in a unique and nonstandard way- this is a truly experimental synthesizer; and experimenting with it yeilds some fantastic results (see sound and video demos below). It can create anything from mellow analogue hums or harsh phasing drones, from sample and hold style biddly-beeps to white noise walls of chaos.

This synth was originally Cacophonos 1, however, when that synth didn't sell, I gutted it and in a last ditch attempt to make some money I made a fancier case and added lots of extra features like CV inputs and blinky lights. It's partly made from some recycled wood, metal and electronic components. All the circuitry is analogue and created entirely by myself, making this a rare and unique, one of a kind analogue synth.

Features
3 x VCOs, square and triangle waveforms, VCO3 has a switch to change between square/triangle or pulse/saw.
1 x VCF
1 x Envelope generator (AHR - Attack Hold Release, activated by big red button)
CV inputs: for VCO3, VCF
Gate input: for envelope
Meter: displays envelope level. Note- meter is larger than standard meter size!
Red glowing tube: displays VCF CV level
Small orange LED: indicates VCO3 CV level

Technical description of operation
The VCOs can be operated at sub-audio levels, acting as LFOs. The envelope is AHR (Attack Hold Release) with Attack and Release time controls and a button to activate it. The VCOs are connected in the cacophonic configuration (diagram below) which, by itself, has vast potential; each VCO affects the next in the loop creating mutating infinate loops of analogue chaos! But there's more; Each VCO can be re-routed into either the signal input or CV input of the VCF, simultaneously, so you could play a 3 note chord or use one VCO to control the cutoff of the filter and the other two as audio inputs or any combination you want!
The filter can also be pushed into some slight soft distortion by sending all the VCOs into the signal input with the level controls turned up to maximum volume.

Maximum voltage range for all inputs: 0V to 10V
CV inputs: 0V to 10V
Gate input: low/inactive range is between 0V to 2V, high/active is between 2V to 10V.
Some protection against over-voltage is included but should be avoided."
