Here you go, this shows how to display the MIDI data in a panel. I think there is also an example in the HISE docs under MIDI somewhere. My version tries to scale the MIDI data to fill the whole panel, so it should resize the notes depending on how far they are from each other (in pitch, not time) in the MIDI sequence. But this will give you full customization over how the notes are displayed using the paint routine.
