Using Battery with MPCXL

Sup. I got the MPC as a controller and sequencer with Battery. Only thing that confuses me is that when I go to Program Parameter I can't freak the sound.

I wanted to use Voice Overlaps and change the Tune from the MPC. Is this possible?

Thanks

Nope. No way of tweaking sounds that are located outside your MPC. Not even possible to make them trigger mono or poly. Only things you can tweak are the sequence parameters. Go tweak them inside your battery. You should be possible to change things dramatically from there. Why need you MPC to do that?
