Are you running ARIA stand alone or as a plugin?
If you're running it stand alone, or as a plugin in a tracking DAW (or a Notation package that doesn't support real time instrument changes in ARIA), simply load your Trumpet in one slot, and your Flugel in another. When you are ready to change instruments, change MIDI channels to the appropriate ARIA instrument slot.
Some hosts can send the necessary commands to change an instrument slot in ARIA. We'd need to know which host you're using to give more specific instructions on how to do this.
