I have just started playing with Notion as I needed a chord sheet for my bandmate to follow. What I found so far is I needed to enable the chord map in SOv4 and one midi track to move into Notion. So your ‘keys’ midi instrument track might be good.

Try moving just that midi track to Notion and see if the chords come along. I have not been able to get an audio track over yet as well.

I may be totally off base but I felt your question at least deserved my little input. I will work with it a bit more today.

If you want to import audio in order to get chords and tab notation, you need something like Capo.
Capo is, on the one hand, remarkable, and on the other, pretty hopeless. Everything I've fed it, it gets wrong, whether it's simple or complex. On the other hand, it gives you a starting point.
It's also now a subscription model, which it wasn't before, so I won't be continuing with it. Mac only too. And it doesn't do proper score notation.

You should be able to Detect Chords on an audio track and Extract to Chord Track in Studio One.

When you send this to Notion, you'll get the Chords as text in the score. No need to send audio to Notion.

Hi All!
Many thanks for your guidance!
Although the Notion 6 pop up does suggest that you can "import Audio Files directly from your Browser", I can't find how that is achieved as yet but I'm working on it!
As suggested by you guys above, after creating the Chord Track, I converted an Audio Track into Midi via Melodyne, imported it back into the song on an instrument track, set up Presence, selected the Track and sent it to Notion and it created the Score with the Chords above.
Bit of a workaround which could have been made clearer in the Notio Manual but, it's solved my immediate problem for the moment!
So thanks again every one!
