Also, our friend Joe Gore details how the whole system works with iPad, including plug-in manipulation and automatic mapping of parameters for plug-in functions. I agree; it’s nicely done.
iPad + Logic + TouchOSC = HOLY CRAP! [sonicgore.com]
Readers do touch upon standardization or interoperability between apps. It’s a good point, and the short answer is, right now, today, OSC doesn’t provide any way to do that. Many of the necessary facilities are there, but there isn’t a way for developers like Apple to support something standardized. It is a real need. It might look nothing like MIDI or later ideas like Mackie Control, both de facto standards (and the latter controlled by just one vendor). But you’d need a way to describe messages that wasn’t recreated by hand each time you use a new app.
