I have an amp with stereo loop as i stated. I can put a pedal into input 1 of my loop and another pedal into input 2 and there will be two different sounds from two outputs. But H9 sounds similar in both channels no matter what time of delay i set in delays A and B. I set A B delay mix on 12 and differen delay times but the sound both in two outputs. I also set routing to NORMAL in pedal settings. Maybe I should set something else in pedal settings? Or maybe i choose wrong algorithms?
For some delay algorithms, it might hard to tell but all delay algorithms are real stereo. It seems that your settings are alright. You may try some pitch algorithms. They are easier to tell the difference between two channels. H910, Quadrovox, Harmodulator, and Diatonic are good options. Set the MIX to 100 and pitch mix to A10+B10. Let me know if this works.
