MIDI Equipment

Here are some sources for MIDI equipment in case I decide to stick with the Arduino and communicate via MIDI:

Female MIDI socket component with breadboard compatible pins - SparkFun Electronics

Various breadboard components from CuriousInventor.com. MIDI IN/OUT modules towards the bottom. Also available is a breadboard minijack socket which might be useful. *Both currently out of stock*

MIDI IN/OUT to USB converter from Amazon. Also see Maplins
