Create an Arduino Orchestra Controller to control and panel of LEDs

[PaulKinlan]

The hub has a pluggable module system that lets you strip out the OSC/MIDI stuff that is alrady there.

A developer could create an Arduino sketch that reads from the serial port and based on the data toggles output pins that attach to an LED array and will replicate what the user sees on the sequencer board.

For example, even though this is Bluetooth you could build this: http://www.youtube.com/watch?v=4lL3AH8_jH4

Or you could get a couple of these and patch them in to a grid... http://oomlout.co.uk/collections/extra-pieces/products/led-matrix-8x8-bicolour
