Hi Hector, Have you downloaded any drivers required for the Alesis USB to MIDI cable? Also, you may need to set it up in the Audio MIDI Setup in Applications/Utilities Make sure that connections from the MIDI Keyboard to your Mac are properly connected and try restarting your Mac, plugging in all hardware and then launch Logic... :) Rounik
