Kingfrog,
Yep, that works for receive...but what about when you want to, lets say select a STS or a registation and you want the Tyros to select sounds on a MIDI sound module, Sonar or any softsynth?

That's not so good, because you can not set your own MIDI bank and PGM change into any user voice in T2/T3. They did not design the Tyros to control anything MIDI even though the note MIDI messages are fine.
