When problems arise in Soundtrack Pro 3, removing the Audio Unit plug-ins may help isolate the problem. Also, some plug-ins may not appear and are therefore not available in Soundtrack Pro 3.

Programs
Soundtrack Pro 3

Solution

Most Audio Units are installed in this location:

/Library/Audio/Plug-Ins/Components

Some Audio Units are installed in:

~/Library/Audio/Plug-Ins/Components

To disable each Audio Unit for malfunction reasons, simply move the file from one of the above locations to another, such as the desktop, before opening Soundtrack Pro 3.

If Soundtrack Pro 3 behaves correctly without the Audio Unit plug-ins, you need to find out what is causing the problematic behavior. To do this, place them back into their original folders one by one, or a few at a time, and close and reopen Soundtrack Pro 3 to see if it works properly. Once the problem reappears, you've identified the problematic plug-in

If an installed third-party Audio Unit plug-in is not listed on the Effects tab or in the Effects menu under the Process menu, you may not be able to verify it. If this is the case, the connection will be unavailable in Soundtrack Pro 3. Check with the plug-in manufacturer for an upgraded version.
