it has a simple design, USB Powered, Midi IN/OUT on the back, and GB Cable coming out of the left side.
the mode switch reminds of an arcade button, he wanted red/green led colours.
it features an arduino nano v3.0 and runs with arduinoboy 1.2.3 (newest version).

so i decided to make a quick video showing him that master and slave modes are working fine in lsdj.
