I cover that topic in details in my manual 'GarageBand 11 - How it Works (see link below). It seems that this type of question and confusion comes up a lot on forums. If the system (and GarageBand) recognize the Device then you get an Alert that a MIDI device has been added or removed. There you can see what (audio and MIDI) devices are recognized by the system.Īnother quick check is to plug the USB device in and out while GarageBand is open. Open the 'Audio MIDI Setup' app (inside the Utilities folder inside the Applications folder). If for any reason your operating system doesn't 'see' your device then it's not GB's fault. GarageBand 'asks' the operating system if there is anything available and if yes, then you will see it in GB (check preferences Audio/MIDI). Your operating system has to 'see' your external MIDI device.
Therefore it only works on a Software Instrument Track in GB. Are you sure you understand the difference between MIDI and Audio?Īs isteveus pointed out your keyboard is sending a MIDI signal and not an audio signal.
