i search and try a lot before I start a thread. here´s my problem.
I´m running reason 4 on imac, my masterkeyboard (CME M-Key USB) is assigned to bus A and working fine.
Now when I put in my slider-/Knobbox (Korg nanokontrol), it´s getting recognized, assigned to bus B and working, but my masterkeyboard gets lost, that is "inactive" and no function anymore.
I tried changing the usb-ports, the busses, what is there more to try?
I installed the korg usb general mac driver, maybe deinstall this one?
WHAT AM I MISSING?

it´s no spam!

thanks anyway

it´s only pictures of the prefences page

please help, it´not my mac, i´m just visiting friends.
I don´t even find the korg driver installed, where is the system32 in here??

is it that I shall not use a masterkeyboard and other controll devices at one time?
