The other day I just got a HD pro unit for my studio. Works great as expected out of the box. I have the HD 500 as well. Now that the HD pro is rack mounted I want to be able to dial in tones with the pro and then, when I need to take the 500 to a gig, transfer the tones to the 500. Is there a converter that will change between the HD pro and HD 500 and vise versa?
