[LAU] Rakarrack source code and MIDI signals

Hi everybody. I'm approaching to the Behringer FBC 1010 midi foot controller and I would like to use it with both Rakarrack and Sooperlooper simultaneously. The problem is that Rakarrack is supposed to automatically assign a preset to every MIDI signal received, so everytime I send a message that I would like to address to SL only, RK reads it too, changing preset when I would like it did not. I'm scanning the source code and trying to use FLUID to edit it, looking for a section where I can see and delete the MIDI signals that I'd rather use with Sooperlooper only. Unfortunately I'm not a programmer and nothing looks familiar to me with FLUID. Does anybody have any useful information about MIDI and FLTK or C++? Is it possible to delete sigle MIDI values in the source code? Thanks in advance. Andrea
