i have a world music jam pack which i would like to trade for a voices jam pack (as in original disc in box for original disc in box). i no longer need the world music collection (since its content is included with the copy of logic studio i recently purchased), but i would like to make use of some of the material in the new voices jam pack (which is not included with logic studio). so -- is there anyone out there who purchased the voices jampack and then for whatever reason decided it was no use to them, who would prefer to own the world music jampack instead? please let me know. look forward to hearing from you, john bertram, toronto
