SYNOPSIS

  # Compare:
  > perl -MMIDI::Simple -MData::Dumper -e'print Dumper \%MIDI::Simple::Length'
  > perl -MMusic::Duration -MData::Dumper -e'print Dumper \%MIDI::Simple::Length'

  # In a program:
  use MIDI::Simple;
  use Music::Duration;
  Music::Duration::fractional('z', 5);
  new_score();
  patch_change(1, 33);          # Jazz kit
  n('zsn', 'n38') for 1 .. 5;   # Snare sixteenth quintuplet
  n('qn', 'n38');

DESCRIPTION

This module adds thirtysecond and sixtyfourth note divisions to MIDI::Simple. These are 32nd: y, dy, ddy, ty and 64th: x, dx, ddx, tx.

NAME

Music::Duration - Add useful note lengths to MIDI-Perl

FUNCTIONS

fractional()

  $z = Music::Duration::fractional('z', 5)

Add a fractional duration-division for each note, to the MIDI::Simple Length hash.

In the example above, we add z-notes, or 5th quarter note divisions

TO DO

Decouple from MIDI and provide a subroutine of lengths.

Allow addition of any literal or coderef entry to the Length hash.

Only require MIDI::Simple and set the Length hash if present.
