Ah, AFAIK, if you want to get MIDI driven sound out of Rosegarden4, you have to use a softsynth via Jackd. Use Qjackctl to start Jackd, then start up the softsynth you want to use and then Rosegarden. It won't take months to figure, I know it can seem daunting at first, but you really are going to want it working from the sounds of things. > However, when I quit rosegarden, I hear a single note play!!

If you're using ALSA, only one application can have access to any device. It's just in use - the port still works & is still recognisable I think you'll find :-) > Other mysteries... > > MYSTERY: Port 64 is 'Intel 82801DB-ICH4 MIDI - Rawmidi 0' [type=kernel] > How do I load sounds into this external midi?

You need to use something like fluidsynth. > MYSTERY: Some midifiles, when loaded into rosegarden have "Imported MIDI" > in channel 1, but nothing there, and things like 'Rhythm' assigned to MIDI > external device #10[D]" (there's that 10[D] again). n In this example, the > file that have this information do not play with aplaymidi This is normal no? - channel 1 contains the original MIDI info or something like that. It's normal to assign the Rhythm track to #10, It's a handy convention, why it should be an external device, I don't know, I can't see from here :-) HTH a bit tim hall
