Hi Jorpe
I have read these posts several times. I just do not get it. On top of that, the manuals add more confusion. I hope you can help. I have connected a cable between an Android tablet and the FR-4X. I have verified proper communication as I can see midi commands sent by the accordion when midi is set to output.
Since you have been successful, you may have adjusted the process since last posting. What items do I have to change in the FR-4X? I think I know, but need confirmation. Also what command(s) need to be sent to change the set, register or user program. I use the default "basic" channel, 0DH. I've tried the midi command CC and PC. I do not see how to format the data.
I am using Mobile Sheets. While the program shows "English commands" such as Program Change, it does not show the actual bytes to be sent.
Thanks
