You may want to attempt to make a cdr with volume adjustments. . .some burners and software, both pc and audio type, can accomplish this; I have recently gotten an HBH that does a nice job with level changes in both analog and digital domains. . . . I can conceive of you making a cdr that had the balance of both types of tracks just how you want it, and then you could just play that cdr rather than the cd itself.
