DESCRIPTION: Kits and enclosures are available at http://groovesizer.com A first look at the Charlie firmware for the Groovesizer. The firmware is proof-of-concept only at this point - it just aims to show that the firmware works with the Groovesizer hardware. The firmware is based on the Illutron 4-voice synth for the Arduino. http://www.instructables.com/id/Turn-your-Arduino-into-a-4-voice-wavetable-synth-w/
