chipophone The Chipophone: An 8 bit synthesizer

Linus Ã…kesson’s Chipophone is a 8-bit synth built into an old electric organ.

All the original tone-generating parts have been disconnected, and the keys, pedals, knobs and switches rerouted to a microcontroller which transforms them into MIDI signals. Those are then parsed by a second microcontroller, which acts as a synthesizer.



The synthesizer is implemented on an ATmega88, an 8-bit microcontroller with 1 kB of RAM and 8.5 kB of ROM. It receives MIDI data at a jumper-configurable baud rate and produces a 12-bit mono line out signal.
