Advice on Arduino and MIDI shield

I am designing and manufacturing a device for a university project that will allow a band member, in this case the singer, to alter the volume of the overall monitor mix they hear. They can only increase or decrease the final mix. The Front Of House engineer should have overall control of what they are doing so some kind of automation can be set up at the main desk so the engineer knows what the output levels are at.

I have since been advised to find out more on MIDI Shields.

I realise this may seem like a totally random post but any input would be greatly appreciated.

go to http://www.arduino.cc and search for MIDI

some sample results: http://www.arduino.cc/playground/Main/MIDILibrary http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1197235191 http://www.arduino.cc/playground/Learning/MidiFoot

I guess MIDI and Arduino is quite easy, many examples exist. If you have never worked with an Arduino please start here: http://www.arduino.cc/en/Tutorial/HomePage
