could not connect to the JACK audio server

[topus]

sono del tutto niubbo in questo campo... quando lancio Rosengarden in Ubuntustudio mi dice sempre

Codice: Seleziona tutto

Rosegarden could not connect to the JACK audio server. This probably means the JACK server is not running.

che devo fare? ???

grazie

devi appunto installare jack

ps ti consiglio di avviare il server JACK da interfaccia grafica cioe installando il pacchetto qjackctl
