OSX 10.4 (Tiger) is not supported for Audio Units.
Not all Audio Units hosts are suitable for Source Elements software as many hosts are 'editors' and not 'mixing' hosts. If you can record, for example, your microphone input with a live reverb, then your host should be suitable.
Source Elements officially provides support for the below hosts. Tutorials for some of these hosts are available.

Apple's Soundtrack Pro is not fully supported at this time, as Soundtrack Pro does not pass all characters from the keyboard to AudioUnits plugins. For example, if your username is 'user' you will only be able to enter 'use'. We recommend you use Source-Connect Pro 3.5 and route your audio signal into SoundTrack Pro.
