METHODS

new

  $d = MIDI::Drummer::Tiny->new(%arguments);

Return a new MIDI::Drummer::Tiny object.

note

 $d->note( $d->quarter, $d->closed_hh, $d->kick );
 $d->note( 'qn', 'n42', 'n35' ); # Same thing

Add a note to the score.

This method takes the same arguments as "Parameters for n/r/noop" in MIDI::Simple.

accent_note

  $d->accent_note($accent_value, $d->sixteenth, $d->snare);

Play an accented note.

For instance, this can be a "ghosted note", where the accent is a smaller number (< 50). Or a note that is greater than the normal score volume.

rest

 $d->rest( $d->quarter );

Add a rest to the score.

This method takes the same arguments as "Parameters for n/r/noop" in MIDI::Simple.

count_in

 $d->count_in;
 $d->count_in($bars);

Play the closed hihat for the number of beats times the given bars. If no bars are given, the default times the number of beats is used.

metronome34

  $d->metronome34;
  $d->metronome34($bars);

Add a steady 3/4 beat to the score.

metronome44

  $d->metronome44;
  $d->metronome44($bars);
  $d->metronome44($bars, $flag);
  $d->metronome44(16, 1);
  $d->metronome44(0, 1); # Use the ->bars attribute

Add a steady 4/4 beat to the score.

If a flag is provided the beat is modified to include alternating eighth-note kicks.

metronome54

  $d->metronome54;
  $d->metronome54($bars);

Add a 5/4 beat to the score.

metronome58

  $d->metronome58;
  $d->metronome58($bars);

Add a 5/8 beat to the score.

metronome68

  $d->metronome68;
  $d->metronome68($bars);

Add a 6/8 beat to the score.

metronome74

  $d->metronome74;
  $d->metronome74($bars);

Add a 7/4 beat to the score.

metronome78

  $d->metronome78;
  $d->metronome78($bars);

Add a 7/8 beat to the score.

flam

  $d->flam($spec);
  $d->flam( $spec, $patch );

Add a "flam" to the score, where a ghosted 64th gracenote is played before the primary note.

If not provided the snare is used for the patch.

roll

  $d->roll( $length, $spec );
  $d->roll( $length, $spec, $patch );

Add a drum roll to the score, where the patch is played for duration length in spec increments.

If not provided the snare is used for the patch.

crescendo_roll

  $d->crescendo_roll( [$start, $end, $bezier], $length, $spec );
  $d->crescendo_roll( [$start, $end, $bezier], $length, $spec, $patch );

Add a drum roll to the score, where the patch is played for duration length in spec notes, at increasing or decreasing volumes from start to end.

If not provided the snare is used for the patch.

If true, the bezier flag will render the crescendo with a curve, rather than as a straight line.

set_time_sig

  $d->set_time_sig('5/4');

Set the signature, beats, divisions, and the score time_signature values based on the given string.

write

Output the score as a MIDI file with the module "file" setting as the file name.
