PC getting filtered even when no filters are on

[matthew]

I am running into an odd issue with the Hapax and the MRCC. I am sending Program Changes via the Hapax, and the MRCC registers them (On the routing page I can see that its getting them on the right channel), however it never makes it to the device its sending it to. If I connect the hapax directly to the device the PC's get through just fine, but as soon as I drop the MRCC in the chain, nothing. It really feels like a filtering issue, but I have no filters set, and I am using the factory settings.

Any pointers?
