Ableton Forum

Sorry but i cant write in english, im from Perù and i have a lil problem with my ableton live 9 and my launchpad, all the time when i try to put the USB cable on my PC does not recognize, what can i do? thanks!!!

Did you select the Launchpad in the Live preferences? In the MIDI tab of the preferences you have to choose which controllers Live should use. You have to select the Launchpad there or Live doesn't know what to do when you plug it in.
