Adafruit DSP-G1 Voice Chip

Transform a humble LPC810 chip into a versatile mini MIDI synth with the DSP-G1 Voice Chip analog modeling synthesizer by Jan Ostman from DSP Synthesizers. Programmed to interpret and produce music from MIDI streams, this chip reads TTL level serial MIDI data and generates sound through a 44.1KHz Delta-Sigma DAC.

The synth features a robust 15-DCO configuration, arranged in a five-note paraphonic structure with a 24db lowpass filter complete with resonance. It also includes AMP ENV, filter ENV, and LFO with either sine or sample & hold waveforms.

Compatible with Arduino projects, it connects to the ATmega TX port to be controlled with ease via sketches. For enhanced sound capabilities, incorporate multiple chips to achieve a multitimbral setup.

Specifications include: 15 DCO, 24db DCF, 2 ENV, and 1 LFO in a 5 voice paraphonic voice structure, TTL MIDI Input, 44.1KHz 16-bit Delta-Sigma PDM, and 19 parameters manageable through MIDI-CC. It operates on 3.3V power and tolerates 5V inputs.

Control the sound dynamics using MIDI-CC: CUTOFF (CC#74), RESONANCE (CC#71), and many others to fine-tune your musical creation. Delight in the limitless potential of this compact synth chip!
