I had an issue yesterday during a performance where the bass was intermittently dropping out. This was after several hours of use. I closed the app and reopened and it behaved for the next hour. On an IPhone 13 Pro Max running 18.6.2.
I see some one else had a recent bass issue. I know you’re working to whip the digital band into shape. I’m sure I can speak for everyone here and thank you for your work on developing this great app, Luke!
