Any way to get mFreak to transmit midi note numbers 0-11 (= C-1>B-1)?

It seems the lowest midi note number I can get the mFreak to transmit is c0 (= midi note # 12.) I’d like to be able to send notes in the c-1 to b-1 range MIDI note numbers 0 > 11). Any way to do that? Using the octave shift buttons I can only get to C0. I know some keyboards allow you to define middle C as C3 or C4, but I didn’t see anything in the settings that would accomplish that.
