pytronome - a metronome in Python

A simple command-line metronome in Python, using the ossaudiodev Python module. Supports programmed input from file. You also can easily change the beats, if you download the source instead of the single-file program.

Version 1.1 released (01/10/2008) Changes in this version:

support to read program from file.
code cleaned up and easy to read and understand
two choices of installation:

download the pytronome single file, put in your $PATH and you're ready to go
download the source tarball, and do the installation by yourself. the advantage is that you can easily change the beats and get a cleaner code.

Some quick usage information:

$ ./pytronome.py --help
Usage: pytronome.py [options]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -m METER, --meter=METER
                        define meter signature     default: 4/4
  -t TEMPO, --tempo=TEMPO
                        beats per minute           default: 120
  -n NUMBER, --measures=NUMBER
                        play just NUMBER measures then exit
  -p FILE, --program-file=FILE
                        play only the scripted in FILE

Here is the content of the example program file:

# this is an example of a program file for Pytronome.
# comments and blank lines are ignored

# we start with 2 measures with Pytronome default settings...
4/4 120 2

# and then 4 more in a 8/16 with a tempo=240!
8/16 240 4

# and finally, go to infinite in a 3/4 at 80...
3/4  80

Note: According to Python documentation, the module ossaudiodev is available only for Linux and FreeBSD.
