Steps to reproduce:

  • Open HALion 6 standalone
  • Load attached preset
  • Load a midi file or record your own. Something that contains chords and sustain pedal
  • Start playback for a few seconds and then press Stop

Script will loop through all the keys and prints the keys which are returned as true by isKeyDown

function printKeysDown()
	for key = 0, 127 do
		if isKeyDown(key) then
			print("Key ", key, " ", isKeyDown(key))
		end
	end
	print("***")
end

function onInit()
	print("Init")
	printKeysDown()
end

function onController(e)
	postEvent(e)
	if e.controller == 120 and e.value == 127 then
		print("Stop Playback")
		printKeysDown()
	end
end
