It will solve any conflicts (e.g., "merge" duplicate controllers and handle nested notes) on the other hand, it will drop unknown events (e.g., lyrics, markers, smpte...) and move sysex messages into banks played at the beginning. -- Alexandre _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
