);
sub filter_notes {
my ($note) = @_;
return $note, $note + 7, $note + 12;
}
sub filter_tone {
my ($event) = @_;
my ($ev, $channel, $note, $vel) = $event->@*;
my @notes = filter_notes($note);
$rtc->send_it([ $ev, $channel, $_, $vel ]) for @notes;
return 0;
}
$rtc->add_filter('filter_tone', $_ => \&filter_tone)
for qw(note_on note_off);
# add other stuff to the $rtc->loop...
