The Nova changes from Performance to Program modes when a Program is assigned to Part 1 of the Multitimbral Performance template.

This is caused by a conflict between the global MIDI channel and the
Part 1 MIDI channel. See the help pdf "a guide to using the Supernova

within this document should be read as 6 parts for the Nova laptop.
