Hello Dpettine16,
if the H90 is responding MIDI Clock tap tempo but not to a preset BPM from your MC6 im guessing the issue might be with the controller. Are you sure the MC6 button is programmed to send “MIDI Clock” on press? Other settings on the MC6 you should make sure are set:
Show Tap menu: No
BPM: Whatever you want
Stop MIDI Clock: No
BPM decimal: 0
