That’s the beauty of it: you can mix & match anything together, tweak that to your liking, then save it as a customized creation.
It would be difficult to absorb all that the H90 can do on day one. It’s important to run through all the onboard controls and gestures at the start.
The online / linked H90 manual is comprehensive. As for H90 Control instructions, it takes a few sessions to get to your comfort zone. It will read exactly what’s on the pedal itself. Makes for a great macro view of the overall picture.
My personal approach has most all of the loading, Preset creation & adjustments on the pedal itself. H90 Control for some fine tuning, Program management, and such. I rarely leave the Parameters page.
