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.
- -t 72
The Tempo will be set; to 72 beats per minute in this example. The default is 120.
- -b 3
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.
- -v 80
This option sets the Volume (or Velocity) of the midi output. The default is 100.
This option starts midiclick in Paused state; you can then start it Playing with spacebar. This option is ignored in -Q Quiet mode.
- -o 128:0 or -o TiMidity
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
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.
This option displays the Version number.
