Is it a known problem that any host supporting VSTs (via vestige or otherwise) will not work with multi-threaded jack? The very-generic message from wine: jack_client_new: deprecated no message buffer overruns jack_client_new: deprecated no message buffer overruns The VST will start (Guitar Rig 3 in this case) but wineasio finds nothing for input or output (no sound in or out as observed from the visual indicators on the VST GUI).
