via this auction"The unit is about the size of a CD but still has a wealth of features to be connected via the included patch cables. Functionality includes: oscillator, LFO, ADSR envelope generator, VCA, VCF, noise source, ring modulation and MIDI interface.
The bC16 functions are controlled by sixteen color-coded potentiometers. Synthesizer sections are connected via the 10 included 2mm mini-banana pin connectors.
The unit is very well made. All the knobs and jacks are firm and operate smoothly. The bC16 is powered by 6 AA batteries (included) or an external 9 to 12 V source. It has an standard mini jack for earphones.
The bC16 was made by a one man company that went belly up and ceased to exist. There is quite a bit of information on the web, however. Check out the videos of the bC16 on youtube. There were only a few made and they are quite rare. I could only find one case of one being sold on the Internet.
This bC16 is in very, very good shape. It has no scratches and is fully function. It comes with 10 patch cables and a "patchable signal inverter" that allows a signal to be inverted before patching it into another section. I will provide the documentation on a CD. The manual is not fully completed. I have no other packaging for the unit. The auction includes the items in the first photo.
This is a really nice, fun synthesizer for a collection or a musician...
The manufacturer says:
The bC16 miniature patch synthesizer packs a fully featured VCO, LFO, envelope generator, analog VCA, analog VCF, noise sources & ring modulator all in a CD sized case CNC machined from 10mm high-grade acrylic plastic.
Fifteen color coded potentiometers control key functions, connections between synthesizer sections are done using twenty-five 2mm mini-banana sockets.
Powered by either six AAA batteries or by an external (not supplied) 9 to 12v source, the bC16 can be used free standing (internal headphone amplifier), linked to an external keyboard/sequencer or MIDI-CV converters, combined with other bC16's, etc...
VCO: The complex VCO (actually two linked VCO's) waveshape can be adjusted through sine/triangle/sawtooth and square wave (with adjustable dutycycle). The VCO can be CV modulated (log response), FM modulated (linear response) or can be driven by MIDI NOTE values. The two linked VCO's can be offset using a control knob, CV or MIDI for rich complex tones.
LFO: Like the VCO the LFO is actually two linked low frequency oscillators with a host of modulation possibilties and waveshapes. Like the VCO the LFO can also be controlled via MIDI.
VCF: An all analog 24dB discrete ladder filter with variable cuttoff (knob and CV), adjustable resonance, specially designed to work from the low voltage busses in the bC16.
EG: The bC16 envelope generator is very easy to use, four knobs (or via MIDI) control the Attack, Decay, Sustain and Release parameters of the envelope. Set sustain to zero and the EG enters repeat mode for long VCS3 style modulation possibilites.
VCA & HEADPHONE AMP: An analog voltage controlled amplifier is provided along with an built-in headphone amplifier (volume control via grey knob)."
