A problem has been reported in version 15 of iOS and iPadOS, in which Apps are sometimes unable to detect a Yamaha musical instrument after making a USB connection.
If you encounter this problem, turning off your iPhone/iPad and then turning it on again will allow the instrument to be detected normally. We have confirmed that this problem only occurs with version 15 of each OS.
As of October 27, 2021, we have reported this to Apple and are considering how to address it.
We apologize for any inconvenience this may cause, but would ask for your patience while we resolve this issue.
