How to route signals from different tracks (in softw) to different outputs on UR44C audio interface

I’m performing on stage with musicians: 2 guitarists, a bassist, a drummer, and vocal. Each musician needs to output their instrument to their own speaker or headphones. I’m looking for an app that allows me to output different signals to different outputs. I have an audio interface Steinberg UR44C. Can I do it with this audio interface and how?

The outputs will be there. You just need to add them in audio connections. Then you can create a mono or stereo output/outputs and send which ever tracks you want to them
