MIDI Program change - external instrument

Hello !

When I select a program, from MIDI inspector, the selected program doesn’t appear on the display of my Yamaha PSR S900.

I have installed the patch list, and everything looks good. I can see that all the banks and programs are there.

The program change works fine, I select for example Strings, and the correct voices can be heard.

I’d like to see the name of the program, to be displayed on my keyboard arranger. Why doesn’t it change according to program change from Cubase ?

I’ve watched YouTube videos, where display on external MIDI instrument change patch name, that’s what I’d like to see too.

Any help appreciated,
