That's a feeling I long for. I got a taste of it by my DAW that lets me play notes with my computer keyboard, and I had a blast with it (but of course I quickly ran into ghosting and range issues).
i am pleased to announce that if you get a music keyboard, (as long as you don't get one of the toy ones) it will actually sense how loud/soft you hit the notes. so that will be instantly a whole new layer of feels that you have been completely deprived of, because the computer keyboard is not pressure sensitive
