On Windows, you could find many freeware virtual piano software. But on Linux, you have no such easy setup or such choice. There are two major pieces virtual piano software – they are Virtual Keyboard<\/a> and Virtual MIDI Piano Keyboard<\/a>.<\/p>\n

You should be sure you have your sound card proper set before you start this – i.e. make sure you can play a file in Totem or something.<\/p>\n

To install Virtual Keyboard:<\/p>\n

sudo apt-get install vkeybd<\/pre>\n
To install Virtual MIDI Piano Keyboard (download vmpk.deb<\/a> to \/tmp first):<\/p>\n
sudo dpkg --install \/tmp\/vmpk.deb<\/pre>\n
After you have chosen one (or both) of the above, install the remaining dependencies:<\/p>\n
sudo apt-get install qjackctl zynaddsubfx<\/pre>\n
After you have installed everything, run the following and restart your computer:<\/p>\n
sudo su -c 'echo @audio - rtprio 99 >> \/etc\/security\/limits.conf'\r\nsudo su -c 'echo @audio - memlock 250000 >> \/etc\/security\/limits.conf'\r\nsudo su -c 'echo @audio - nice -10 >> \/etc\/security\/limits.conf'<\/pre>\n
After restarting, open the JACK control center (Applications >> Sound & Video >> JACK Control), and start the JACK server. Once it is started, click the Connect button at the lower left corner. Start ZynAddSubFx and Virtual Keyboard\/Virtual MIDI Piano Keyboard and go back to the JACK control center, select Connect, then the ALSA tab. Connect the Virtual Keyboard\/VMPK on the left to your sound card and the ZynAddSubFx. Connect your sound card on the left to the right. The result should look something like this:<\/p>\n
