Hi everyone, I am using the Xkey Midi keyboard along with Garage Band and the Yamaha Mobile Music sequencer. To pre pare music for live performances, I need to access You Tube videos and play along with the music to familiarize myself with the song. This I do in Split View, but unfortunately I am having difficulty in adjusting the 2 separate audio tracks. I'm not even sure if this is possible with the iPad Air 2, but I need to increase the volume of the Midi keyboard or lower the volume of the You Tube video. Ideas anyone?
