ChimSyn is a little, fully customizable, midi patch synthesizer. You can use it on it's own, or as a midi input device. The ChimSyn has (30) 2mm sockets, which allows for almost infinite possibilities.
The bC16 miniature patch synthesizer wraps up a fully featured VCO, LFO, 24dB VCF, VCA, envelope generator, noise source, ring modulator and headphone amplifier all in a crisp, white, round, CNC machined acrylic housing the same diameter as compact disc. Powered by six AAA batteries the bC16 can be used on it's own, with the in-built MIDI converter, driven from the SM16 (sequencer) or attached to other bC16's and so on.
