NAME
vmpk - Virtual MIDI Piano Keyboard
SYNOPSIS
vmpk [Standard options...]
DESCRIPTION
This manual page documents briefly the vmpk program.
This program has standard Qt programs options.
Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn´t produce
any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or
software, internal or external). You can use the computer´s keyboard to play MIDI notes,
and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI
notes from another instrument or MIDI file player.
