Zuki, I'm sure that you know that the VP-550 is a stand-alone keyboard VH. I've owned one for some time now (as do many tour groups) and it is one of the most fun and potentially useful tools I've ever owned, particularly if you're a lousy singer like me. The one thing that might be inconvenient for some people, is that is does not have built-in transposition. If this is a real problem for you, you can always midi it to another keyboard that does.

I can't answer you question definitively because I'm not familiar with the G70's harmonizer, but I suspect the answer is no, as it would be diffcult to duplicate all the functionality of the VP550 inside of an arranger. It's just too purpose-built.

Even I can lay down some reasonable background vocal tracks as you can literally "talk" the words or be slightly off pitch, or sing in a monotone. You could really wow a crowd with it, though.
