I am using the code that Sparkfun publish with the device. Also trying code from the MIDI library for arduino. Nothing works. I've tried writing my own code, working with the MIDI library and tweaking the Sparkfun code. Even the code from Sparkfun does not work on its own.
MIDI is a really simple protocol, and yet it's foxed me! I think it might be a hardware issue (e.g. not enough current to the shield, or my homemade boards)
I've tried this:
And this (Example arduino sketch at the bottom of page):
And all examples from the arduino MIDI library.
No MIDI in, nothing works.
