Audio Triggering + Mouse Event latency

[Scott Rossi]

One thought:

I imagine that a "virtual instrument" is significantly more effective when
relying on the keyboard (multiple sound triggers possible) compared to the
mouse (one click at a time), so unless your project has some other
requirements that were not shared, it seems that relying on the keyDown
message could improve the usability of your app.

You may also want to review the keysDown() function in your tests.

Glad to hear you're close to a solution.
