ColorTones is an iOS Core Audio sample project that builds on several basic principles of musical instrument design: triggers, envelopes, wave generators.

It includes CTMusicHelper, a class which ports concepts from the Overtone project to Objective C, by making use of OCTotallyLazy - a functional programming extension to Objective C collections.

This project is based upon https://github.com/dreamwieber/sine-wave https://github.com/dreamwieber/noise-trigger https://github.com/dreamwieber/shaped-noise https://github.com/dreamwieber/harmonic-drone
