If your sound hardware does not support MIDI, you need to run a software sequencer, e.g. timidity++. For JACK output, use this: timidity -iADq -Oj --sequencer-ports=1 This one will use PulseAudio (through libao) for output instead: timidity -iADq -OO --sequencer-ports=1 Kevin Kofler -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
