I only recently got a fast enough computer to test the Falcon, so I'm
not familiar with which programs to use for testing Falcon sound.
That is why I wanted others to test my patch. Please tell me which
programs to use when testing the Falcon. I believe that improving the
Falcon sound is as simple as getting down to work.
