I just recently purchased a JTV59 and HD500 combination after having a Variax 500 and POD XTlive. Wondering if anyone else has had this problem?

I am getting an audible glitch / dropout when changing patches via the VDI cable. It is especially noticeable when changing tunings. It's a real problem. I used to be able to switch from Drop D to normal tuning on the fly for different parts of a song and it was smooth as silk using a copied patch that just changed tunings. Not anymore. The glitch is audible on all patch changes while playing as well.  

I kept my original VDI cable but found it unreliable with the new rig. (worked great before) Now, a new Bestronics cable and things are stable but the glitch is still present. The overall rig seem to have worse latency than before too but that's a different discussion.

If this is "normal" then I will have to return the whole rig.

Thoughts?
