I lost the sound – Band Tools Review

My cello teacher wants me to play a scale while listening to the "drone" of the key note. Your app is perfect for that. However, today the tone had no sound. The metronome did, but not the tone. I tried rebooting my iPad (v7.1) but that didn't work. I deleted the app and reinstalled it. Now it Works fine with a blue background instead of rose pink.
