One feature I've become acustomed to with the SD1 is the second mic input. This allows me to adjust volume and effects for each mic for each song that is saved in registration - very useful, since I usually work with female vocalist. I'm now considering a few keyboards (SD5 and G70) which do not have that 2nd mic input.

Is there any work-around that would allow me do this with only 1 mic input? Such as, a saved registration sending a midi message to a digital mixer? Would that work? Thanks for any suggestions.
