Reply to converting HID to Midi?

what software can you use for a mac? (HID to Midi) Can you convert regular typing keyboards into separate midi controllers? Such as plugging two extra type kybords into my comp making three total keyboards.
(1 for typing, 2 for trigg etc.)

I use ableton and reason so i know that ableton can map to my keyboard but if i plug another one i dont believe it will work.

any thoughts?
