[bv74]

Hi,

I just upgrade from LMDE5 to LMDE6 (debian 11 to 12) and GO is mute !

1. when I click on one key on PC's screen of GO I heard notes. The link between GO and loudspeaker is OK.
2. When I click on organ keys it's mute !
3. check on MIDI event seems OK. The link between organ et GO seems to be OK :
   
4. When I click on organ key I've no "grey" key on GO keyboard.

Do you an idea to solve this issue ?

Best regards.
LMDE6 (debian12)
GO 3.13.2-1 (appImage)
10 Go RAM allocated to GO, 16 Go RAM in total

I answer to myself :
With the install as described #1113 it's running well after setting each MIDI objects.
Same action with appImage don't succeed.
