Reaktor 5.5. bug in Reaper?

Works fine for me here. Reaktor by default only receives on MIDI channel 1. So I can very easily get it to NOT work if I click on the Record Routing button and then MIDI Input/Map input to channel: and set this to anything other than Source or 1 (my keyboard transmits on channel 1). I still get MIDI activity on both the TCP channel and in Reaktor itself, but since its not on channel 1, no sound is coming out. Also try it in a brand new project to eliminate the possibility of other routing issues. I'm relatively new to Reaper and am still getting used to the fact that if any other channel is Solo'd, Reaper doesn't automatically show all others as Muted, even though they essentially are. I'm assuming this isn't your problem, but I just wanted to mention it. I'm guessing its the first issue, as it only pertains to MIDI controllers but not MIDI items in the editor. Comfort
