Opens a virtual <MIDI> piano <GUI>. It just works on <Ubuntu> 20.04: https://askubuntu.com/questions/34391/virtual-midi-piano-keyboard-setup/1298026\#1298026
VMPK is a virtual device that replicates what you would get by connecting a physical MIDI keyboard to your computer. It is not a <software synthesizer> on its own. But it does connect to a working synthesizer by default (Sonivox EAS) which makes it produce sounds out-of-the box.
TODO: then I messed with my sound settings, and then it stopped working by default on the default "MIDI Connection" > "MIDI Out Driver" > "Network". But it still works on "SonivoxEAS".
A <hello world> of actually connecting it to a specific software synthesizer manually on <Advanced Linux Sound Architecture> with `aconnect` can be found at: https://askubuntu.com/questions/34391/virtual-midi-piano-keyboard-setup/1298026\#1298026

Reasonable default key mappings to keyboard covering 2 octaves.
3 multiple simultaneous keys did not work (tested "ZQI"). This might just be a limitation of <ciro santilli s hardware/Lenovo ThinkPad P51 (2017)>[my keyboard] however.
TODO how to save to a `.mid` file? https://askubuntu.com/questions/709673/save-as-midi-when-playing-from-vmpk-qsynth
