Rush videos use a midi that they edit. They usually also use a template. But, if you are asking how to add a keyslam, I think you are doing it very wrong.
Thank you,well at first it looks hard but its easy (in my opinion) you make your own melody first (don't forget the text notes) then add the bass (key slam and more) and finally the arts (the triads and more) and that's all. Don't forget to put every melody,bass and arts in different tracks. Edit: I recommend using domino midi editor
