"This is a fully working unit. The knobs are original factory, though later knob style changed. Later units had colored knobs...

Manufacturer Description:
The bC8 is probably the smallest production synthesizer in the world and certainly the cutest.

Packed into the bC8's tiny round body is a hand-assembled gold plated circuit board, eight high-quality potentiometers, a stereo jack socket, push-button, no less than four LED's, battery holder (3xAAA cells) with a robust stainless steel base.

Sophisticated digitally based oscillators are housed on the DSP as well as an innovative recording system and internal control voltage patching. Choose between single-shot and repetitive envelope generator modes; use the separate ATTACK and RELEASE knobs to create long and soulful drones; select the recording system to record and playback complex patterns of control knob movement, speed up or slow down the pattern playback to add extra glide detail or confusion, override any of the controls during playback to adapt, complicate or simplify your composition.

The bC8's VCO goes from the subsonic to the upper end of human hearing, introduce subtle amounts of modulation from the LFO or envelope generator to create gentle vibratos or progressively wind in more than 700% modulation for almost impossible-to-predict and perhaps never-heard-before sounds. VCO is capable of 'thru-zero' modulation (frequencies run backwards).

To sum up: Eight LFO and four VCO morphing waveshapes, 128 different patchings, deep modulation options, wide ranging ATTACK/DECAY envelope generator and recording sequencer in a hand-built-by-one-man-in-a-tiny-factory-in-England - pocket sized - self powered - round package carefully machined from high-quality plastic.

The bC8 recorder records each knob position when the button is pressed and released, as well as the duration of the button press and the time between presses, when playing back each of the recorded positions is replayed with a smooth glide between values.
