It is my first time using a MIDI keyboard.
When connect to the computer I have no idea if it is working.
I want to use in Musescore but it also do not respond to the keyboard.
I'm using an old "Yamaha PSR-520" and a "CH345 MIDI 1" controller from Alliexpress.

It's not needed to install any program.
Musescore by default was not using ALSA audio on my installation. It was only needed to select ALSA at preferences menu and it just worked!
to see if the MIDI was recognized just type aconnect -i
This last 'CH345' is my MIDI controller and it is shown only when connected.
