Hi Robert. One thing I noticed recently is that instrument count doesn't
work as expected until the MusicDevice has been "Initialized." Also, if
you're asking for properties of a Component instead of a ComponentInstance
(returned by OpenAComponent), you will get an error (not sure if it's this
one).

Good luck,
Daniel
