I read through the messages below and some of the errors encountered are relayed from jack (the lines starting with JACK ERROR:). Possibly jack isn't being truthful about it's RT settings. A little over a year ago there was a lot of talk of bugs in certain versions of glibc that caused similar errors. If you run: 'getconf GNU_LIBPTHREAD_VERSION' what does it print? my system prints NPTL 2.3.5. What distro are you on and how uptodate is it? You have probably already told me this and I have forgotten...apologies. Also, I recall having problems with RTness while using qjackctl a long time ago. .. I think I stopped using it because of that particular issue... not that think that this has anything to do with qjackctl. <....> > JACK ERROR: cannot lock down memory for RT thread (Cannot allocate memory) > set realtime scheduler: Operation not permitted > midi thread 8662 _NOT_ running SCHED_FIFO > JACK ERROR: cannot use real-time scheduling (FIFO at priority 9) [for > thread -1290273872, from thread -1290273872] (1: Operation not > permitted) > JACK thread not running SCHED_FIFO, try to set... <....> > Also, the sound is full of clicks and pops and breaks constantly and > is overall horrible. :( I get a lot of fifo underruns, whatever that is, > concerning the wave tracks: > > FIFO 0x10c2e768 underrun... > WaveTrack::getData(DX7 IV) fifo underrun > FIFO 0x10c0a9e8 underrun...

Yes, this is intentional, I think all similar audio tools keep their audio files, you never know what the user wants. We should have a gui for purging unused files though. In the MusE package there is a file 'utils/checkwavs.py'. You can try running it from a song-dir. It compares the set of available wave files against the ones that are used by the med-files in the same dir and prints which wave files are not used by any songs. The script is short, crude and working. > > My first project in Muse is failing miserably, to sum it up: the sound > is terrible, choppy and > clickety, I cannot get RTC to work, Muse takes forever to load the project > and crashes often. when it crashes the jackd process crashes as well. > > I feel that Muse has taken a life of it's own and I lost control over it > and it is producing sound the way it wants because I am a buffoon > that can't harness it's possibilities. I'm sorry to hear that (though I like the way you tell it ;) Do I understand you correctly that it works better if you start MusE as root? If that's the case there is atleast hope. -- http://spamatica.se/musicsite/ |
