I have heard of people doing this and wanted to play around with it. Usually I just double the track and offset it a few ms. I was reading on here somewhere where people were running the effect out into another track. Basically creating a track of just the delay or reverb and panning that to the opposite side of the original recording. Is this a good idea? How would you do it in Reaper? I have no idea how to use the buses and stuff yet.
