 * puredata aka pd when run with `pd -rt` as well;

 * supercollider's "sclang" can do so

 * qsynth/fluidsynth (depending on config and backends:

    midi.realtime-prio' and 'audio.realtime-prio')
I don't know about rosegarden, qtractor, hydrogen, seq24, ams, csound,

chuck, aeolus, bristol, ecasound, snd-rt, a2jmidid, lmms,  midish,

qmidinet, gstreamer, CLAM, etc, etc. I suppose all ALSA-midi/sequencer

instruments that can be played, recorded or used live should set up RT

scheduling; not all of them do that [yet]. Same goes for non-JACK ALSA

or OSS audio apps.
Many authors/maintainers of audio software are subscribed to LAD.

If it really boils down to collecting a white-list: call there. Some

closed source apps: eg skype or baudline may try to setup RT

scheduling?! and there's A/V apps and video-players, too.

`ps -Leo rtprio,ni,pri,comm` will tell.
I need to say that I'm not a friend of black/white listing. What are the

alternatives?
ciao,

robin
