It's hard to tell what's going on. The speaker feeds back guitar as you'd expect. Sensors on the speaker send gesture data which is mapped to the flute-guitar model synthesis instrument. I'm switching between mappings on the laptop (which I'd like not to be doing). It's more fun when I don't know which mapping I get and I can just play.

If you wish to be bothered, you can look at this paper, explaining the rig in more detail.

Unfortunately, Ensemble Modem does not get around as much as we'd like.

ooohoo! cool. Ensemble Modem? Barely a pixel from having to change the
name! Is this a regular gigging group?

So the synthesis is controlled through the mouse/keyboard, playing
through the handheld speaker, mixed with the guitar which feeds back?
Is that right?
