July 27, 2017, Update: Keynality now includes Audiobus 3 / IAA / virtual MIDI support!
Keynality is a key aware musical instrument designed for composers, performers and producers to assist with making music with unfamiliar or unusual keys. It provides a musical palette which can play internal sounds from the built-in synth and sampler (powered by AudioKit!)
Or, it can drive any midi sound source.
Congratulations on the app!
