Help Sysex load X3

[Tdtchavi]

Hi,

I have lost the internal battery with all the sounds except GM and I can not restore them from a PC, (the keyboard does not indicate that it is receiving data).

The connection appears to work fine because I send notes from the PC to the keyboard and they sound. Also if I play the keyboard I see the notes on the PC. Sending Sysex from the keyboard to the PC also works. In all cases in the USB cable the LEDs light up so I see that the data is sent from and to the keyboard, however it does not recognize them when sending sysex from the PC (it does not even show on the screen that sysex data is being received) . It must be a problem with the configuration of the keyboard or the PC software.

I am using Midiox on the PC. As for the keyboard, I have followed the instructions in the manual regarding the configuration of the Global mode (filters, memory protection, etc.) but there is no way. I've tried changing the delay and buffer size and it doesn't work either.

Can you please help me?

Thank you!
