So I’ve spent most of the evening trying to import a score from C14 to Notion 6. Notion will not open an xml file made in Cubase, nor will it open either type of MIDI file. Is this a normal mismatch between Cubase and Notion, or is there something unusual going on?
There is no possible mismatch. MIDI files are a standard, and all DAWs can open them. You didn’t say what kind of xml file you used.
This question seems more likely for the Notion forum.
Notion 6 is incomplete, buggy and abandoned.
Maybe not ‘open’ - but what about trying an import (into an existing project).?
