I'm a real noob here, just got my CK88! But in playing around with it, I'm trying to find a voice that can be used as a pad for songs of the classic rock groups. Background vocals as done in the '70s by the Eagles, Pure Prairie League, etc. doing supporting harmonies with doos, or ahhs.

Seems like the eight CK choirs are all large, female churchy samples with no close mics. Is there any way to add voices to the CK or what is the best way to edit an existing choir to achieve this effect?
