I wish it was just to scroll and not load but currently it is scrolling and loading. I'm using cc's I think. I'm using the disaster area dpc 5 to do this.
There are pedal functions to scroll and not load and there are pedal functions to scroll and load. You just have to assign the MIDI CC to the correct pedal function. If you click the Pedal settings button in the bottom menubar of H9 Control, select MIDI Settings, and select Assign MIDI CC messages to pedal functions, you'll see the pedal functions "Increment Preset", "Decrement Preset", "Increment and Load Preset", and "Decrement and Load Preset".
