SYNOPSIS

  $ export MIDI_EDITOR=timidity
  $ export SCORE_VIEWER=xpdf
  $ ly-fu --instrument=banjo c des ees c des bes c aes

DESCRIPTION

Plays and possibly displays lilypond snippets entered at the command line. The MIDI_EDITOR environment variable should be set to a program that can play MIDI files, and the SCORE_VIEWER optionally set to a PDF viewer. (Or edit the source code as necessary.)

http://www.lilypond.org/ and in particular the Learning and Notation manuals should be consulted to understand the lilypond syntax.

OPTIONS

This script currently supports the following command line switches:

--absolute

Assume lilypond absolute notation.

--instrument=instrument

Set MIDI instrument (see lilypond docs and ZSH compdef script).

--layout

Save the MIDI and other various files (they are unlinked by default).

--open

Show the score via the SCORE_VIEWER program.

--partial=lilypond fragment

A lilypond fragment played once at the beginning.

--relative=note

Specify what note the input is relative to.

--repeats=count

How many times to repeat the (non-partial) input.

--silent

Do not play the MIDI.

--sleep=seconds

Kluge sleep before unlinking temporary files (if SCORE_VIEWER slow, or so forth).

--tempo=tempo

What the tempo is (in quarter notes, e.g. 120 or the like).

--verbose

Show output from lilypond and the MIDI player.

FILES

A ZSH completion script is available in the zsh-compdef/ directory of the App::MusicTools distribution. Install this to a $fpath directory.
