midiclick - generates a metronome click-track on MIDI channel 9

The MIDI::ALSA module is used to create an ALSA client.
The keyboard interface, allows real-time adjustment of the delay parameters. If you don't want the interface (e.g. in a Makefile), the -Q option sets Quiet-mode.
This is midiclick version 1.2
The tempo will be set; to 72 beats per minute in this example. The default is 120.
The bar-length will be set; the bell will sound every 3 beats in this example. The default is 0, which means every beat clicks and there are no bells.
This option sets the volume (or velocity) of the MIDI output. The default is 100.
This option starts midiclick in the paused state; you can then start it Playing with spacebar. This option is ignored in -Q Quiet mode.
This option sets the ouput-port to which the midi output will be sent. You can check out the available ports with the command aplaymidi -l or aconnect -ol. The default ouput-port is the environment variable $ALSA_OUTPUT_PORTS
Since Version 1.3, you may supply a comma-separated list of ports, e.g. -o 20,128:1
This option runs midiclick in Quiet mode; there is no user-interface, and the metronome just runs with its Tempo and BarLength as given on the command-line, until it is interrupted. It can be useful in scripts.
