Hi, I bought a YAMAHA BT-01 that worked perfectly with two different ipads old generation under IOS 9.3.5, but not working now with my new Ipad Pro IOS 14.4 and 14.4.1 updated.
My Ipad Pro sees the BT-01 but no midi data are sent from OnSong that I’m using for lyrics triggering my keyboard through hexadecimals.
Same problem is occurring with another Ipad 6th generation and Iphone XS under 14.4 and 14.4.1 updated.
I upgraded the BT-01 firmware from 1.04 to 1.07 but nothing changes, it still does not work.
Thanks for help.
