So i tried to setup my keyboard to my computer and some weird things happen. The first thing i did was testing it with midi-ox. Everything seemed to work until i started playing chords or just 2 notes at once. It seems like it only can register one note off at a time, but the weird thing is that it sends 1 note off and the rest note on when i release multiple notes at once, so it does register something. But if i remove one finger at a time works fine as you can see on the second image. I really don't know what to do, could it be the interface? It was a cheap one from china.
Your USB/MIDI interface is this model:
which does not work: not only does it garble any messages using running status, but it also corrupts SysEx messages.
Buy any other USB/MIDI adapter.
