Hi soundsubs,

When you’re working on the edit tab up top on H90 Control, on the bottom of that window you’ll see four other tabs, the last of which is “Preset Library.” Click on it and you’ll be able to highlight which slot you want to work with at the top, A or B. On the right side of the page you can narrow down the preset list by effect types and/or algorithms types. Simply clicking on a preset name will load it into the slot you have selected. Once you have customized both slots with new presets, you can press save on the top right to save it to the current program number you’re working with.
