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 ([email protected]) 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. The PCB layouts and schematics (in /hardware/shruthi/design/pcb) are released under a Creative Commons cc-by-sa 3.0 license - except for some discontinued filter boards which were released under a cc-by-nc-sa 3.0 license. Documentation, analyses, simulations and 3D models are released under a Creative Commons cc-by-sa 3.0 license.
