If you’re looking for a simple setup, Example 1 is probably the most straightforward. You can use the H90’s routing flexibility to create a dual stereo setup for live (wet/dry), and a summed mono output for practice.
Set the H90 to dual routing mode, assign Out 3 as a mono mix of Out 1 and 2. Then route that into your amp/cab sim pedal for headphone use or DAW input.
If your amp/cab sim pedal needs stereo in, you could go with Example 2, but that would require more complex routing and more inputs on the sim.
Since you have a MIDI controller, you could set up presets or toggles to switch between live and practice modes quickly.
