Hey all,

I've had a little idea that I think might be worth "implementing". This is it:

Controllers, (in the musical sense like a MIDI controller knob), have always had a certain
"update" period, ie MIDI cable 31250 baud, or from a MIDI file PPQ's etc.. you the the idea.

What if we were to make a "callback-update" system, where the controller (read Arduino with a sensor attached)
runs an OSC server, which whenever gets a /<arduinoName>/poll command, returns the value of the sensor?

there is already a paper that describes a system to do precisely this, and liblo implements its half of the deal.
