I'm pretty new to reaper, but I've used similar software before. My problem is that when using reaper's effects, I can only get a dry signal until I've already recorded and I'm listening to the playback. Is there a way to change settings on the effects before recording and still be able to hear it? If it matters, I'm using a Digitech RP155 with the USB output going into my computer.
Monitor through reaper. What are you trying to use?
what you're looking for is fx monitoring. you could create aux tracks and send them as headphone feeds
Click the little speaker icon on the track you're recording to.
