Thanks guys, I've got the MIDI editor somewhat figured out now. My next question is, how do you set the proper BPM so that the gridlines match up with the song (as they do on the charts in RB)?
I tried doing it by "trial & error", changing the BPM and playing the song with a click track over it to see if the clicks are in time with the song. While it may start out that way, it gradually gets off-time as the song goes on. I know that some songs intentionally change tempo mid-song, but that's not the case here.
So basically, how do you figure out the exact BPM of a song? Is there an automated way to do that in Reaper?
(Note: I'm just experimenting using an MP3 I have on my computer. I don't have master tracks or anything. I realize that may be part of the problem as I'm assuming it's easier when you have an isolated drum track.)
