The classic SID Commodore game synthesizer chip is combined with the 70's AY-3-8912 arcade game sound chip and placed inside an old Teletalk office intercom box.
An Arduino Micro provides programmable access to all the synth parameters of both chips along with a full complement of controllers to twiddle those paramenters.
The controllers include MIDI I/O, 6 sliders, 6 light sensors, 4 switches, a soft pot, and volume controls for the voice outputs.
