Notes & Comments

This demo shows how to use the Musical Instruments package that's part of QuickTime using a NoteAllocator component.

The user is prompted to pick an instrument - the result of that pick is then printed out - its ToneDescription.

The program then makes a new NoteChannel to play a note using the Nylon String Guitar sound

General Comments

- QTSession.open and close:

A QTSession.open will perform a gestalt check to ensure that QuickTime is present and is initialized. This is a required call before any QuickTime Java classes can be used.

When the user closes the window the program will quit, first calling QTSession.close to terminate QuickTime. It is necessary for programs to call QTSession.close if they have previously called QTSession.open in order to shut down QuickTime properly.
