Pretty much all the up market (More expensive) modules can map anything anywhere; however the SD2 was designed as a cheap little module for adding some great sounds.

So long as your arranger can output standard Midi assignments (Bank/Program Change, volume, pitch, modulation etc.) then you can easily select any sound on the SD2 you wish to use, however its editing capabilities (Which are extensive) require special codes to operate them. (Both vArranger and Live Styler software arrangers have this already built in for the SD2 (It can also be integrated in Wersi instruments from the 90s Mosys )
