From the developer:
SynthTest allows you to pick a MIDI source, a MusicDevice AudioUnit and an Effect AudioUnit to play with.
There is no purpose to SynthTest anymore. Use Apple's AU Lab.app that comes with the developer tools instead. It is much more featureful, with support for multiple tracks and audio I/O.
The source code to SynthTest is ancient, and will not compile as is. You're on your own with this source; I can't support it anymore.
You may want to check out more Mac applications, such as V-Synth Librarian, M-Audio Key Rig or VirtualDeckBrowser, which might be similar to SynthTest.
