ahh.... the next section of the tutorial (about outbound MIDI) includes:...

MidiMsg msg;

...to define the variable. it works fine. inclusion of that line in the above code (of course) makes it work too.

perhaps that should be clarified in the tutorial??

cheers!

...and thanks for a maillist which is so amazing that we get answers without you guys even having to do anything!  ;-)
