Mixing Reason & other inputs (realtek) live > stream

[Nickargall]

Hi folks
First, please excuse my english (I'm french) or if I do not post in the right place

I'm new on Reason and can not manage to get what I want :

I 'm looking for a way to loopback my Reason/Asio sound so that I could mix it and make it go out through "classical" PC Sound (realtek audio device) and stream it through Twitch, Discord, anything

I tried many things (VoiceMeeter, virtual audio cable, AsioForObs) but none of these could catch the sound coming live from Reason

The solution I found is based on a ReaStream vst plugin and special configuration in OBS, but i'd love to find something simple that could work with any software

What i'm looking for is simple :

Reason / ASIO > Realtek output (mixed with other sources) > fun

Can anybody help me ?

thanks if you can !

regards
Nick
