You might want to take a look at some previous implementations of
similar ideas (using console keyboard for MIDI). They use the ALSA

Some of that code will be useful, but both of these run in user space and
use the Xorg keyboard inputs. This means that if I have a synth connected
to virtual kb, as soon as I try to change the synth patch, I loose my
virtual keyboard access because keyboard follows focus to the synth
application (which is what we want almost always). That is why I have to
run as a system user.
