hi. after readiing about this subject about using two seperate usb keyboards in windows xp i think i finally found one software solution to using both, i.e one for windows tssks and the other mapped to ableton. http://www.hidmacros.eu/
this is the video that convinced me that this is what we windows users neededhttp://www.youtube.com/watch?v=XKq7vjKgcJY
so far i have managed to configure some keys of just one of the keyboards as SHIFT + (letter numbers (macros) then assign them to ableton without any probs so far. the good thing about this soft is that it only stores the macros for individual keyboard hardware id's, i.e a keyboard no.1 or keyboard number 2 and soforth. so if you unglugg it it will not confuse it with a different keyboard, allowing you to have different keyboard setups for different purposases
i can just imagine using six NUMPAD keyboards
Another great thing is that it detects usb mice !!!! and you can set command to that too! just imagine the posibilities (Possibly mapping to X/Y controlls in ableton? yet to test that part out, purchasing some old cheap trackballs..
thanks to this forum for inspiring me to create "keyboard" midi controllers
