NMusic is a music generator for iOS using async methods and iOS midi synthesis.

The key components are:

• Key.cs defines musical Keys, Chords, and Progressions. It also contains a database of common western-music progressions.

• Song.cs defines the root Song class that is made up Sections (like verse, chorus, bridge). Each Section contains a ChordProgression and a tempo (BPM). Melodies, Baselines, etc. are generated for each section.

• Instrument.cs contains the functional interface for controlling (playing notes on) a MIDI instrument. You can create these and control them yourself, or create a Song that will control its own instruments.
