Problème résolu !
J'avais ce message :
wine lancement.exe
001c:err:module:import_dll Library MSVCR100_CLR0400.dll (which is needed by L"C:\\windows\\Microsoft.NET\\Framework64\\v4.0.30319\\mscorsvw.exe") not found
001c:err:module:import_dll Library mscoree.dll (which is needed by L"C:\\windows\\Microsoft.NET\\Framework64\\v4.0.30319\\mscorsvw.exe") not found
001c:err:module:attach_dlls Importing dlls for L"C:\\windows\\Microsoft.NET\\Framework64\\v4.0.30319\\mscorsvw.exe" failed, status c0000135
000f:err:service:process_send_command service protocol error - failed to write pipe!
0009:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.
J'ai dl la dll en question « mscoree.dll » et l'ai placé sous "C:\windows\Microsoft.NET\Framework64\v4.0.30319\mscorsvw.exe".
Le clavier fonctionne, j'ai uniquement ce message :
wine lancement.exe
0053:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.
0071:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.
Pourtant le son fonctionne parfaitement.
