Shruthi-1, a digital/analog hybrid MIDI monosynth.

This project is a redesign of the original Shruti-1, with a spec'ed up CPU, and a focus on easy upgrades/modification of the analog section. The ATMega644p allows new features in the firmware -- a larger selection of oscillator algorithms, a bigger selection of wavetables, and a tiny sequencer.

Original developer: Emilie Gillet (emilie.o.gillet@gmail.com)

The firmware is released under a GPL3.0 license. It includes a reimplementation of the formant synthesis algorithm used in Peter Knight's Cantarino speech synthesizer.
