A sound synthesiser built from scratch. It implements oscillators, filters, an arpeggiator and a looper. It's written in Rust, a systems programming language, due to the performance critical nature of producing sound in real time.

It works by receiving commands such as NoteOn, NoteOffand SetPatch which could originate from user interaction or MIDI protocol instructions, for example, and producing a sound signal that can be sent to an audio output device.

An example of usage and runnable demo can be found in rust-synth-gui.
