I am struggling to map my V-Drum hi hat to Superior drummer. I can set it to either open or closed, but not combinations of sounds. I am also unable to access the keymap (midi layout) for some reason. The only one that appears is for EZDrummer’s Pop/Rock kit. The Roland hi hat (VH 11 I think)produces many variations of sounds from closed to sloshy and even includes a super tight sound. Is there any way to make the two work together?
