How to change direct monitoring on UR-RT2?

Hello,

I want to use Steinberg UR-RT2 to connect my guitar and Tonex guitar software. However, even if I set everything in Tonex as I have, only the clean guitar signal (input signal) comes out of the RT2 output. So only direct monitoring of the input and not the output from Tonex. How do I set RT2 to not only do direct monitoring?

Thank you.
