Regarding the forthcoming update which adds Ableton Link intergation and more, here's what the Modstep folks told us:

"We have already submitted the first update, Modstep 1.0.1, to the AppStore. Due to the iTunes holidays, this will take until the end of the year/beginning of next year to go live. The update will feature bugfixes and Ableton Link-integration.

"Although we officially don’t support the iPad 1, all MIDI functionality including MIDI-streaming via studiomux currently works on iOS 5.1.1."
