I have the latest Studio One 3.3 and the latest Notion 6. When I have an all MIDI track song in Studio one and I assign the MIDI tracks to component/audio unit VI's, then exporting to notion hangs. When I copy/past the MIDI tracks to a blank studio one song with NO VI's assigned to those MIDI tracks, it exports fine. I have a public Vimeo Video showing you this: that is vimeo video 172783107. What's up with failed export? Why does it hang? It's a big problem that notion does not support component VI's. I can't just switch because my old sessions that use the AU VI's won't load any more .that's a problem .
