I recently reached out to NotePerformer support to ask if there were any plans for integration with Notion and asked the reverse question to Presonus as well.
It became apparent that there might be some technical discrepancies on both sides that would prevent this integration.
Having approached both companies, I feel that there is a need for further investigation into the compatibility of the two products.
I also feel they both need some motivation to work it out.
So, please vote for this post if you want NotePerformer to perform your music in Notion.
