"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 we did in our example photo), it can be connected to the ATmega TX port and controlled through a sketch. More chips makes it multitimbral
