The SD2 manual does not have a CC2 in the list. Maybe it can do Breath Control, I don't know, as I don't have nor use the EWI, but if the SD2 can be made to respond to Breath Control CC2 data, it may be that you would have to use some circuitous route to do so, maybe Sysex or the like.

But first I'd hook directly to the SD2 input and send the Breath data from the instrument and listen to see if there was any response. Isolation like that could prove or disprove a lot.
