OK, and this is what I was driving at. (After all, in most rock
concerts, there's someone else doing the mix and technical support
during the performance as well.)

By "control data" I mean what you call "performance signal data".

For that, you'll probably have to read *my* long-promised CMJ paper...

OK, but I think the term "filter" is misleading - it suggests that
information is being removed or rarified, rather than used in a
generative manner. But if we stick with "filter": presumably a
composer/musician could be improvising with the filters' processing
algorithms at the same time as the dancer is producing the initial

The signal-to-sense algorithm could also be regarded as dynamic,
generated or controlled by a musical collaborator during the dance
performance. This is the sort of interaction which interests me.
