The Receptor has notheing to do with it. As it stands right now, the Receptor is a little under powered for BFD2. If one can get it installed, it is tough to use because of increased graphics and DSP requirements. I thiink that they are working on it, but for now maybe this will help.
All you need to do is set up the Zendrum to change notes to your requirements.
In BFD2, you assign those notes to the instrument articulatios that you want. Save your MIDI map.
You can use the velocity settings in BFD2 to fine tune the performance!
Follow this link to some tutorial videos about MIDI mapping in BFD2. http://fxpansion.com/index.php?page=10&tab=84
There is also a live video of a performance at a clinic in London. All of the music in that video is being triggered from BFD2 with no other software being used.
