Man I'd love to use Sonar again but after they refused for years to fix a very specific MIDI bug (a showstopper for me), I finally had to give up and switch to another DAW. I have used "Cakewalk" from the time it was a simple MIDI-only application all the way up to Sonar X1. That's where I got off the bus. Also the extremely buggy X1 release didn't help.
