If you have just bought a new Mackie DL mixer, you will have to download the Master Fader 3.0 iPad app, which is not compatible with this version of My Fader. This should be clearly stated here where people download this app, not just over in the Master Fader app details, where it may or may not concern owners of that app. It has been almost 4 months since Master Fader 3 was released and still no news on when this app will be updated for compatibility
