Make your own mini MIDI synth with DSP-G1 Voice Chip analog modeling synthesizer by Jan Ostman at DSP Synthesizers. It's a tiny LPC810 chip programmed to read in MIDI streams and make music!

The chip reads TTL level serial MIDI data and outputs sound through a 44.1KHz Delta-Sigma DAC. The synth is a 15-DCO structured as 5-note paraphonic with a 24db lowpass filter with resonance. It also has: AMP ENV, filter ENV and LFO with sine or sample & hold waveform.

If you want to use it with for example Arduino (as Adafruit did in Adafruit's example photo), it can be connected to the ATmega TX port and controlled through a sketch. More chips makes it multitimbral
