Great! Congratulations!

Yes, I see. Depending on the situation you could also keep track of
the state of the leds in ChucK and only send a single message at a
single change. In the past I got around flooding a DIY interface to
some leds in that way. Using both techniques in suitable situations
might cut down the bandwith even further.

Anyway, you already cut down the bandwith needed to almost a 10th,
quite a nice optimisation!
