I came from Sonar 8.3.1 also. The only thing I prefer in Sonar is the way they do MIDI drum maps. On the audio side, no comparison. Once you learn the routing capabilities, you'll never want to go back. Every time I go back and work on an older Sonar project, I end up appreciating Reaper more. Take the plunge...I highly doubt you'll be disappointed. Regards, DB
