Fully dynamic music may be a little expensive. I'm not sure. But if you cut a track to a parts of 5-10 seconds that will be played interactively, that will work. And yes, I need everyone who wants to help.
Fully dynamic music is AFAIK only possible with sequences, but these are mostly low-quality and hard to implement. I want to implement interactive music with streamed files and support Vertical Re-Orchestration (different music "layers") and Horizontal Re-Sequencing (different segments). You can find both in TP.
When I could do this for the game that would be great. Maybe I should post that in the project jobs section?
