Probably really a stupid thing I've done either upgrading to X2 or adding and octa capture! When I go Preferences metronome the First Beat and Other Beats boxes are blank and I dont know how to popoulate them. Checked that HI PING and LOW PING files exist in the C:\cakewalk content\Sonar X2 Producer\metronome folder so I must be doing something wrong

Right-click your SONAR shortcut, and hold Shift while choosing Open to launch it. This will allow you to re-"personalize" SONAR, part of which is setting registry paths for things like Metronome samples. 

Thanks , perfect! done
