ummm, I don't think this will really help guys.

For example in one song, there are at least 5 times where it slows down, then goes back to the original tempo.

I have to get to the actual tempo track and change it properly. It is obviously programmed in a specific way, and it shouldn't be hard to change it, it's just understanding how to get there and modify it.

I could do it on my old keyboard, but it changes other parameters because it doesn't "understand" the way it is programmed in other ways. For example, a text file midi, or "karaoke" file, will work fine before I load and save on my old keyboard. Once transferred back, the text is screwed up and it will not work.

So I'm trying to avoid that problem...
