Brain V2 - midi to Roland V4ex

Looking at the Brain V2 with just 6 x buttons so that we can hopefully get the midi commands in to start a fade from one source to another. 6 Buttons will give us enough options so simply from that point of view but not sure if the commands and addressing the roland unit requires can be entered into the brain v3 software. Any one have any ideas on this ??

thanks in advance.
