Help with Midi Routing?

So I've just started using Reaktor, and I'm ttrying to figure out how to record my synths in a DAW. I'm using Reaper right now, and i've got my virtual instruments recognized and connected, but Reaktor just doesn't recognize my midi keyboard when it's routed through Reaper. When I launch Reaktor alone, it's fine, and my drum machine (doesn't need midi input) plays through to the DAW perfectly. I'm sure it's a problem with how i'm supposed to be routing the midi to Reaper but I'm not sure what i need to connect.

 

is the midi in indicator 'led' of reaktor blinking on incoming midi?
if yes, its most likely a problem inside of reakor.
if not, something went wrong with the midi routing inside your daw.

 

Yes, it's the midi routing in reaper that's the problem

 

then i can`t help much. have used it only twice to test mpe and never again.
midi in driver settings?
set record active on track?

 

I have similiar problem that ocured recently (also using Reaper).
The problem isthat some of the reaktor instruments are working fine but some of them (Monark , Factory Library ..etc) dont have sound output.
When i change channel from 1 to omni still no sound from them .
Blue led midi is blinking btw.
Also when i open midi editor in reaper and write notes or klick on them with mouse sound is there... just not from midi controler .

 

since you are 2 now, you both should maybe start to talk about software versions and os.
since lots of reaper users are hanging around here and it seems them have no trouble...
maybe its a system specific bug?

 

It was a system bug in my case afterall...
Just changed the usb port on my PC , last windows 10 update seems to mesed my usb ports somehow:.
