Euro modded Chimera BC9 Synth (work in progress)


flickr By Chris_Carter_

"I decided to rehouse one of my Chimera Synths into a Eurorack module. The BC9 seemed to most obvious choice as it has CV/trig inputs and the size fits the format well.

The first stage was to see how practical it would be, and as it happens it took only an hour to dismantle the original and mount it onto a copper board. The next stage will be to add holes for the 10 status LEDs and attach a Doepfer power cable (5v). I may also remount the whole thing on an aluminium panel."

KORG Monotribe How To Guide on Installing XRF Wireless MIDI


"What are these XRF modules? they are an amazing little device that enables us to give them serial data and they will transmit it to another module very easily. The plan? to take the serial connection on the Monotribe and plumb it into the module thereby making a wireless serial link with our PC for sending and receiving MIDI data."

ELEKTRONIKA EM-04 SOVIET ANALOG ORGAN | BRASS | STRING MACHINE


via this auction

"Electronika EM - 04. There is a one master oscillator in the instrument. Due to this oscillator a possibility of instrument's detuning in the process of operation is eliminated. This generator shifts a pitch of the instrument on an octave, "slalom-effect" and refines the tuning +/- 1/4. Because of split of the manual into 2 sections, the volume of each part may be adjusted.

Specifications:

— Total audible range - 7 1/12 octaves
— Keyboard's volume - 4 1/12 octaves
— Mains voltage - 220V +/-10%
— Dimensions - 790x490x155 cm
— Dimensions, 890x355x102 mm (31" x 19" x 4")
— Weight, 20 kg (approx. 44 Pounds)
— Also contains 1.126 gramms GOLD, 6.143 SILVER"

"The mods we have installed on this synth consist of 3 main sections, Filter mods, FM mods and Audio mods.

FILTER MODS:

Cutoff & Resonance Knobs: The new resonance knob can take the resonance well into self oscillation and far beyond what is normally programmable from the front panel. This can produce the kind of screaming tweeter eating top end and subsonic bass that gives these machines a whole new range of sonic possibilities. The filter cutoff knob allows you to perform long filter sweeps for those squidgy burbling analogue lines that you could never actually perform on a Poly800 before now. Both parameters are still also controlled by the normal programming methods which can set the range of the knobs control.

12dB / 24dB Filter Response Switch: Somewhat mysteriously the filter chip used in these machines has both 12dB/Oct and 24dB/Oct outputs but only the 24dB one is actually used. This mod adds a switch to select either a 24dB or less drastic 12dB filter response

VCF CV input: This socket round the back of the machine adds an external 0 to 5v control voltage input that controls the filter cutoff. The new filter cutoff control knob is disabled when a jack is plugged into the socket.

FM MOD'S:

These consist of a source selection knob and an FM (frequency modulation) amount knob. Essentially VCF FM allows you to modulate the filter cutoff at audio frequencies to create all kinds of clanging cross modulation and bizarre alien splatters & sweeps. This effect works best with the resonance cranked up into self oscillation which is where the new resonance knob mod comes into its own. The source selection knob allows you to select one of four sources for the FM signal. These are DCO1, DCO2, Noise and audio input. The audio input takes its signal from before the input level knob so you can use the audio to modulate the filter cutoff but remove the actual audio signal from the mix. The source knob also has an off setting.

This Poly800 still produces all the normal sounds possible with this unit when the new controls are not in use. It runs from either 6 x C size batteries or an external 9v power supply.

Listen to the soundcloud demos below to hear the kind of extra sounds that can be produced using the new mods."
