When you manually enter notes, does it play correctly the first time also ?

If the keyboard is "fresh" -- meaning it has not played a midi from the 
Mac/Casio driver since being turned on, it will play correctly once.  (This is 
the same for midis from the web.)

And is it doing this with any other software ? I also assume that the 
transposition isn't visible on the score in Aria Maestosa.

Since there are no transposition functions in the driver, I'm afraid I cannot 
help there ... I know that some keyboards have transposition settings, but they 
wouldn't appear magically after the first play.

What might happen is that, for some reason, Aria Maestosa sends unexpected 
control codes that modify the transposition settings on your keyboard. Did you 
check with Aria ?

I haven't been able to test with other software but the midi's play
correctly on the PC (e.g., quicktime).

My keyboard will transpose if explicitly set to do so.  I've checked the
setting and the midi does not appear to do that.

I haven't checked with Aria M yet but will.
