Jeff Holtzkener released Concentric Rhythm in April 2017. This weekend he released the first update to the app, which honestly could have arrived in May 2017. We'll assume it got lost for a bit, and treat this like the app equivalent of found footage.
What's new in Concentric Rhythm v3.0:What's new?
•Audiobus 3 MIDI
•Export MIDI files
•Autosaving (restart each new session where you left off)
•Clipboard for copying and pasting tracks
•Many bug fixes, big and small
Thanks to everyone for your suggestions, support, and patience!
