Got VEP up and running on my G5 PPC Quad. Great! Being on an older Mac, we're talking 32-bit mode operation.
A few difficulties... For one, certain AU plugins inserted in an effects slot (either on the Master Bus or directly on an Instrument) block all signal from passing thru. Three examples: Stillwell Audio, Vibe EQ and Verbiage, and the Apple AU Pitch plugin. Once inserted, all sound stops. Clicking "bypass" on these plugs works, however.
On the flip side, there are plenty of other AU plugs on my system appear to work just fine, including XILS3, Korg MS-20FX, most of the other Apple AU stock plugins, Magnus Ambience.
Curious to know if the fault lies with the individual plugins or with VEP.
