What midi I/O usb interface for my own DIY controller??

I’ve seen that MIDIbox’s software is made for a specific hardware configuration, that shares anything with teensyduino…

So i’ve searched for MIDI controller on Arduino, i’ve found only the MIDI libraries
http://www.arduino.cc/playground/Main/MIDILibrary

and this
"MIDI Controller
Website: noisybox.net
It is primarily geared at being a sample trigger – you can turn the encoder knob to select a controller number, and press one of the 12 keys to trigger a sample in that “bank”.
