External ("aftermarket") pitch bend/mod control???

[jake88]

Kind of a general yes or no question that I couldn't find an answer to.

I just got a Radias-R, and i'm putting it in my M3, but if I take it elsewhere without my M3, i've got a smaller Midi Keyboard that can tag along. HOWEVER, my midi keyboard doesn't have pitchbend/mod wheels:/

Is there any like...little external module that's just for pitch bending that I could buy? (midi i'm guessing would be the only way to incorperate that)

anyone know what i'm talking about, or know where to find something like this?
