I recently got an old second-hand Yamaha PSR-350 synthesizer keyboard. I don't have any trouble playing, but I would like to make use of the MIDI function. There are 2 MIDI ports, midi-in and midi-out.
I bought a midi-usb interface and tried to connect it to my laptop but I can't seem to find how it works. What I would like to do is for example to write sheet music in MuseScore with my keyboard.
Here is a screenshot of QJackCtl: image
How can I make it work?
