The Instrument
The interface is designed to reduce the time between having an idea and hearing the result. The chorded keyboard allows one hand to write code while the other adjusts values with the knobs, for example.
The Synthesizer
Designed to play, mix, and modify audio samples on the fly.
The Language
Construct a graph of nodes that modify sound as it flows through them. Inspired by existing environments i've had experience with, such as Max/MSP and Sunvox. The language itself is an extremely minimal variant of Forth designed to efficiently operate on queues. Steep learning curve, but very fast to write once understood.
