The inability to have multiple processors and being limited to 6 routable IR ports on each one is the biggest reason we havent sold much prodigy. The last RTI job I sold used an XP8 and i think 6 PCM-8 modules.

The prodigy is great and very flexible with even system builder, but I still find it to be a little lacking in expandability and find anything more than the basic programming to be much more time consuming and difficult than RTI.

Oh and their IR library is useless. They don't even have samsung TV discretes. I find myself learning in discretes from the RTI library on every job Ive sold...
