I've changed the midi interface:
I've been able to downgrade both files to 2.7: still no sound.
I've updated the synth with the two 2.8 sysex: no sound again.
I noticed that 'global parameters A, 1 to 16' work normally, but 'global parameters B' don't work.
If I ask for GP B 1 > some leds are flashing, 1 to 6, etc ... If I press one it lights off, the sens cursor is not active.

I can hear the Chorus, I also can change his rate whith the sens cursor.

What can I do 1 2

thanks
Fred
