Yes I have cited both fine scholars during the development of tidal and will continue drawing from these. There is something to be said for thinking outside the standard midi/piano model though, at least with the kind of music I like to make.

Yes 'span' is perhaps the most immediately understandable word.

I don't think I've felt the need to decompose a Tidal pattern, although I don't doubt there are useful applications for doing so.. > Again, I don't think the relationship between between our score-based > languages and classical FRP (events and behaviors) has been fully examined. > This is in part what I hope to continue doing in music-score. I'd be very interested in such an analysis. I'm not even sure whether to claim anything about the novelty of Tidal's representation.
