I have been trying, unsuccessfully to use a Duemilanove (I've tried loading each of the MIDI codes out there) to a Midisport 2x2 to Live.
I've followed all the ITP examples, read Tom's MIDI post, and everything else I can find but to no avail.
I think my problem is in the interface between my breadboard and the Midisport. Using the code from this tutorial http://itp.nyu.edu/physcomp/Tutorials/MusicalArduino I can get the button to send data out to PIN 1 (an the Tx led lights up) but on the Midisport I dont see the MIDI IN led light up. I can connect another MIDI controller to the Midisport and its works so I know the problem isn't there. Really I can only imagine its the way that I've got the midi jack wired or the jack itself. It's not a jack like the ones on the tutorial, it's a 5 DIN jack that has two legs on the front as well, similar to this: http://hsp.manufacturer.globalsources.com/si/6008800535125/pdtl/DIN-connector/1031379374/DIN-Socket-Connector.htm Could that be a factor?
Any direction appreciated.
