Hi there, I've recently moved from Pro Tools to try our Reaper as possible alternative but have experienced some problems. I'm using a digi002 interface Mac 1.83 Ghz Intel Core Duo 2 GB Ram OS 10.6.8 Basically I recorded a guitar track yesterday and all seemed fine. However, when I add a new track and start either recording or playing there's no playback or sound. Once this happens I can no longer playback any of the tracks. The problem seems to start when I add a plug in to the second track but it seems unlikely it's cpu related as I only have two plugins on the other track. There's also an error message that sometimes comes up (independently of the above issue) saying I've lost connection with the hardware interface. Any thoughts? Thanks, Dominic
