Brad, thanks again for the info. I tried using two otg adapters running opposite of each other and that finally did the trick. So yes, it was indeed the cable. Thanks again. Switching usb settings was the final trick.

Brad, thank you for the information. I really appreciate your time in answering. I do not see any usb midi setting on my phone, nor is there any indication the piano is even connected to the phone. Its a brand new keyboard, and a new Galaxy Note 20 ultra so I'm not sure where the fault is. Perhaps I just received a bad keyboard? Thanks again.

I'm using android, I forgot to mention that. Thanks

I bought my son an S300 for the sole purpose of him using an app as a learning aid. The s300 will not connect to anything. I've used multiple cables, multiple devices, multiple apps...but nothing works. I've even ordered more adapters that plug into the back of the keyboard at the micro USB port. Does anyone have any insight that might help before I send this thing back to Amazon? Thanks in advance.
