I’ve tried setting the H910 and used the expression to manipulate the delay/feedback but I don’t get the right results – it almost sounds like something the UltraTap is doing but he’s using the Pitchfactor to get the results. Any help with how this is done is much appreciated! Thanks! 

Have you used H9 Control? You didn’t tell me you have a PitchFactor or H9 but it’s OK. You can use H9 Control app to control your H9 or PitchFactor (for PitchFactor you would need a USB cable). In H9 Control there are much more presets. Please check out the F8 PHOTON BEAM preset of the H910/H949 algorithm in the app.

If you don’t want to use the app, here I’ve attached a screenshot, from which you may see those parameters.

Thank you! Yes, sorry – I have an H9 Harmonizer pedal. It seems like it is the Photon Beam preset that might be tweaked a little bit. THANK YOU!
