[LAU] - an on the fly midi re-mapper?

Hi all, I may not be naming what I want to do correctly so here is the long version. I have a Behringer BRC2000 midi controller, connected to pc through usb. It has 108 rotary knobs and buttons that, by default, send midi signals in midi channel #0. One can alter the channel of each controller by entering EDIT mode and selecting the new midi channel. This is not fast for real time operation though. What I would like to do is read the value of one of the buttons that the surface offers and depending on the value of that button, (on or off) I would like to modify the midi channel of all the controllers of the surface. To give an example, say the button is OFF , then all the controllers send midi data on channel #0 . Then I press the button and then all the controllers send midi data in channel #1. If I use the 4 buttons at the bottom right corner of the BRC2000, I can effectively access all 16 midi channels and thus have a whooping ( 108 cc - 4 addressing buttons ) * 16 midi channels = 1664 different controllers at my disposal. Is there an application out there which I can program to do that? Surely I can develop a C++ application based on jakc API to do that, but I wonder if there is something ready out there. If something like that does not exist, would anyone be interesteed in developing it? Thank you for your help.
