How do I change the rate of a single track?

New to Reaper and I feel I may not be asking the right questions or even tackling the issue correctly to begin with.

Say I have a fast paced song and I want to throw in a track that is slower. If I change the playrate it modifies all tracks, but I want it to affect only one so that I can match their bpm.

Before I was doing probably a horrible thing by loading an individual track, changing the rate, saving and then adding it back as a new track.

if i understand your question...

you can modify the playrate of a clip by dragging the side of the clip with the ALT key held down. or you can double click on it and type in a new playback rate. note also the pitch of the clip will be preserved by default; you can turn that off in the same dialog if you like.

does that help?

I'm not quite sure what ALT does, I think it just changes the song position but maintains the measures it is held at.

However double clicking did work! I didn't notice the playback option there before and was scouring through all the FX's. Thanks!

You were ALT dragging on the track. ALT Dragging the edges time stretches the track, so it would have done exactly what you wanted too. Double clicking works too and should have the same effect. Use whatever workflow you like best.

Ahh I understand what I was doing incorrectly now. Also, if it is not too much trouble, how would I find out if the two song's bpm's match after I change the rate?

Inside of Reaper? Would double clicking and viewing the bpm's work? I honestly don't know if it keeps it updated. If it doesn't, you'd just have to do some math. If you slowed the track by 1.5x, your new bpm is OldBPM/1.5.

Doing things like this extensively is definitely more suited to Ableton than Reaper, which is why there aren't as many features geared towards it.
