I recently got REAPER POWER! from Amazon and I’ve been extremely impressed with it so far. It’s helping me to see how much of REAPER’s capabilities I’ve been missing (you can try out REAPER for free by the way, and a personal use license is only $60.)
I keep finding out about new things I can do with this software and new ways I can streamline my work flow so that I can work in a more efficient way. When you’re trying to do something creative you want to be able to do all of the technical things as easily as possible.
If you’re a REAPER user (and I don’t think I’m ever going to go back to using any other DAW) then I definitely recommend getting this guide. It’s great.
