I’m using a new iPad (the one with the headphone jack). Been using StageTraxx for backing tracks up until now. Now, I wanted to use sounds from, say Ravenscroft piano, or SampleTank, via midi keyboard, while playing the track.
I find that if I have any other sound app running, then the backing track won’t play in ST. I hit the “play” button, and nothing happens. If I enable “combine USB and Headphone jack”, then the track will play, and I do get audio from the other app as well. The trouble is that this combined audio is very quiet. The backing track volume, and the other app audio is about a quarter of the volume it is without the “Combine USB and headphone jack” setting enabled.
Is there something I’m doing wrong?
