METHODS
All filter methods must accept the object, a MIDI device name, a delta-time, and a MIDI event ARRAY reference, like:
sub drums ($self, $device, $delta, $event) {
my ($event_type, $chan, $note, $value) = $event->@*;
...
return $boolean;
}A filter also must return a boolean value. This tells MIDI::RtController to continue processing other known filters or not.
drums
