Well, by editing midi data I don't mean working with fragments created by a 3d party. I illustrated what I mean in the video I posted earlier. It is when a music keyboard is used to come up with a melody, to try out sounds and to record some phrases, but then all the notes are edited, other notes are drawn with a mouse, some automations are added, drum loops can be also created from scratch. Even vocals in modern music can be tuned and quantized. I'm not saying that it is better, in fact I think it can be a reason why we have so many meaningless songs nowadays; with all this developed processing it's easier to hide the lack of idea in the first place, and software synths and libraries sound so good that it is easier to impress a casual listener. But it's hard to fight progress.

I see that you sort of expand your keyboard with a computer, which helps it to stay relevant. I had an impression that you also got another keyboards, was I wrong? SX900?
