I just updated my audio interface to the m-audio fast track pro. Since updating when I open any DAW it's not reading my MPK49 keyboard for some reason. When I open Maschine it doesn't see it anymore. I have the mpk49 connected to my macbook pro via m-audio uno sport (which is usb). The operating system I'm running is a mac osx 10.6.3. Does anybody know why maschine isn't seeing my keyboard now?
