64          The following example implements a simple MIDI controller filter.
65          It causes all MIDI volume control change events (MIDI CC#7) to be dropped.

68    on init
69      { MIDI controller number for MIDI "volume change" events }
70      declare const $volumeCC := 7

73    on controller
74      if ($CC_NUM = $volumeCC)
75        { $EVENT_ID is a built-in variable which always reflects
76          the ID of the event which caused the execution of this
77          specific event handler instance, i.e. here it reflects
78          the respective MIDI control change event }
79        ignore_event($EVENT_ID)
