A friend of mine and I want to jam together on our laptops using Live. I've got a Mac, and he's got a PC running Windows 7. Using MIDI to sync the two laptops is very unreliable; even with Live 8, there is noticeable clock drift, and if we want to change the tempo, the laptops go out of sync and everything sounds terrible until the MIDI clock "settles".
On Mac OSX, this is a no-brainer: use the network MIDI interface and airport (or ethernet), and everything works great. But how can I sync a Mac with a PC with the same level of reliability and synchronization?
