Still trialing X1. My New problem: I have a synth track with Guitar Rig 5 in the fx bin. The effect is turned on, sound is going through, everything is hunky dory. Every now and then, while playing with clips in the track (recording, looping, playback, editing etc), the sound will just stop going through Guitar Rig. It's still there in the fx bin, it's turned on, but there is nothing going through it (i.e. the meters in Guitar Rig are showing nothing, and the sound is dry). Turning it on and off doesn't work. Deleting it and putting it back doesn't work. The only thing that works is restarting Sonar. So frustrating! Does anyone have any idea of what might be going on? It's not CPU overload, this is a very light tune and the Guitar Rig CPU is at 6% or so.
