Created attachment 407820 [details, diff] Adapted patch for gentoo timidity can't use jack devices (using the -Oj flag): $ timidity -Oj -iA jack_client_new: deprecated TiMidity starting in ALSA server mode Opening sequencer port: 129:0 129:1 129:2 129:3 Couldn't start JACK device (`j') (the last line of output happens when any MIDI device is connected to timidity, e.g. via qjackctl or rosegarden, no sound is produced even though it would with -Os [ALSA output]) Also I had the same result with both jack and jack2. (Same problem in arch linux, so description taken from: https://bugs.archlinux.org/task/40906 ) Patch: https://projects.archlinux.org/svntogit/packages.git/tree/trunk/timidity-jack.patch?h=packages/timidity%2b%2b
Same issue with 2,15 and the patch solve it.
