I have activated Rewire. My sample rates in Studio One and Notion are the same. I get Notion listed as an instrument in Studio One, but can't get any further. Dragging Notion from the browser in Studio One creates an instrument track, but I see no way to select a Notion London Symphony instrument to use in recording. Midi data is going to the track created, but no instrument sound and I can't see any way to choose an instrument from Notion to use.
