pro tools rewire host?

Hiya Trying to use the fxpansion vst>rtas wrapper in pro tools le and get no audio, have also tried using numerology in rewire mode but still no audio comes through in pro tools (other instruments do work from numerology in rewire though). Has anyone come up with a solution to this or had other experience - some rewire host that works for aalto in pt or other method of getting it happening? Would love to use it inside pro tools somehow! As an aside I've emailed Randy about the possibility of rtas or getting the wrapper happening, and had the response that yeah definitely he'd like to get that going - but in the meantime wondering if there's a workaround (beside just recording the synth in another daw and then pulling that audio track over to pt).
