Battery usually starts off with cell 1 being C1, cell 2 being C#1 and so on... but u can set them to what u want. Try putting Battery on a spare FX channel and add a Midi Out. Put the Midi Out and Battery on the same port number (the number on the right). You'll need to enable multiple outs in Fruity to get the samples to come out of seperate FX channels, rather than the same.
But as IQ said, why battery? Fruity is approximatley 1,000,000 times more flexible, and when u render a project to a wave on a decent setting pretty much does battery in the nuts anyway.
