From Create Digital Music:
Link is a marvel – even if you never touch Ableton Live. Grab some iOS gadgets, put them on the same wireless network, and you get rock-solid sync that responds dynamically to any tempo change on any device.
But, come on. Love you iPad as you may, you don’t want to play only with apps. Maybe you want a Elektron box or an AIRA TR-8 or an ElecTribe syncing along. A new app, LINK TO MIDI, does just that one thing, easily. You still get dynamic peer-to-peer sync with all your other apps. But by adding LINK TO MIDI, you can also output old-fashioned MIDI clock to your hardware.
