I'm pretty new to the entire bussing/routing concept. I used to always just load plugins on respective tracks without any routing whatsoever. Reaper has the function of sending a track to both the Master channel and an effects bus (well, in Reaper, a "track" can also function as a bus). So I create a track with the desired effects loaded, then route the desired tracks to the effects track. For example, 2 rhythm guitar tracks routed to a track with Mulitband compression. The Mutiband track feeds the Master channel. In what type of situtation would I want the rhythm guitars going simultaneously to the effects track and the Master channel?
