While we’re on the subject of mobile music this week, I’ll just put this out there: does anyone know of attempts to build MIDI output interfaces for newer Linux and Palm devices? Using the original Palms, many people worked with hacked/DIY HotSync cables. I’d love to see that on the new Palm Centro. Or Windows Mobile. Or Symbian. Or anything, really. And what about all these great new Linux handsets starting to emerge? MIDI hardware isn’t hard to do, but what’s the device side like?
