Thank's for all your answers ; unfortunately, I've not succeded until now ..... But I've not a lot of time left to spend now...perhaps later...so I fear that i must reconnect my atari falcon with cubase audio : great problem to print correct scores with the actuals printers, but no trouble in use !!! cordialement, PS : I think it would be great to get a cd with all stuffs nneeded, to make a linux midi station work properly ; with my poor rtc net connection, it's too diffcult
