Hi there,

Any chance someone can add a quick note (pun intended) to the MIDI example + web site page? I think newbies (like me) could be made aware that the example won't work if the Arduino is plugged in via USB because then you can't use the TX digital output. i.e. You need external power if you follow that tutorial.

It would have saved me a few hours this afternoon if I'd known that. On the plus side, I learned a lot while trying to work out what was going wrong. :D
