I launch qjackctl, then qsynth, then qsampler, then vmpk. vmpk sees fluidsynth in the MIDI connections dialog but it doesn't see linuxsampler.
The workaround is easy: make the MIDI connection in the ALSA tab of qjackctl and it works fine.

Discussion

  • VMPK (using RtMIDI functions) enumerates and filters the existing ALSA sequencer ports in the system having the port type flag SND_SEQ_PORT_TYPE_MIDI_GENERIC, that means "This port understands MIDI
    messages." according to the alsa library documentation:
    [url http://www.alsa-project.org/alsa-doc/alsa-lib/group___seq_port.html#g43e52ce669add7af811a5c59abe25faa\]

    This is the same policy used for instance by aplaymidi, from alsa-utils. If you execute "aplaymidi --list", it doesn't show linuxsampler either. LinuxSampler should add SND_SEQ_PORT_TYPE_MIDI_GENERIC to their sequencer ports.
