Hi folks, Got chatting to Mathias on the LAD mailing list. Want to help bring Muse along if I can. Sure is looking good! So I use Mandrake 10.0 w/ 2.6.7-sds.mdk12 from Thac's. Kernel has lsm and I use Realcap Allcaps=1 any=1 gid=29. My user accountis added to group 29. This gives RT priveliges to audio apps. (Most anyway. Some need LD_ASSUME_KERNEL-2.4.22) Running Jack 0.98.5 from Qjackctl 2.9. All on Asus mobe w/ Ath. XP 2500, 512MB DDR2400 & Delta 1010LT. So I run Muse up. The rpm I used is also from Thac's. Would not run out of the box. So I bring up a terminal and run it from there in user. I see options and that VST is compiled in. I NEVER have been able to get vst, wine, fst to work right so I eliminate that (-V) still won't fly. App starts but Jack shuts down the connection. Muse complains about "-performance issues, etc". I see a "realtime variable option (def = 50) so I set that to like 80. Now Muse runs. I'm happy....until I try to load a soundfont into the softsynth. ( I don;t have any hardware synth modules so I really NEED softsynth support) The soundfont loads and Jack shuts Muse down again. Yes, yes, "try it all as root" I know! :) So I try it all running su tonight and still getting much the same thing. I get a little further along, like the sound font loaded and all the midi channels configured. But when I import a standard midi file, it dies again. Mathias, you said there were some issues with FLuidsynth if set gid? Or something like that...Where do I go from here? Cheers, R~ |

Are you able to run any other lowlatency programs correctly ? Basically I think your machine is not tuned good enough. Pretty much all these problems are due to jack kicking MusE out due to loss of realtime. Everytime I have had similar problems it has been due to tuning issues. 2.6 kernels are just not as good as 2.4, yet. I suggest that you downgrade to the kernel in contrib 2.4.22 lowlatency(whatnot). I use it to great success. You could also check your interrupt priorities and stuff (there is info about this in the installation document on the MusE wiki I think) > > Mathias, you said there were some issues with FLuidsynth if set gid?

You get errors saying something like "failed pinning sample data to ram". I don't think this has been cleared out (I'd guess this is a tricky one, especially if fluidsynth itself is involved, but what do I know).

I don't record on it. The updated Alsa drivers in this kernel, along with some other features that make headless operation a little more efficient, I'm reluctant to return to 2.4.22. I have it there to boot if needed...but I have not needed it. And at some point, more folks are going to have to get on board for the 2.6 Kernel eh? Perhaps I'll keep poking around for solutions on 2.6 and they may be of use to others... > > > > > Mathias, you said there were some issues with FLuidsynth if set gid?

Alsa Modular synth, several > others. Okay, I wonder if it could be found out what they set the thread priority to. Since you mentioned that it helps to increase it that might be a clue... Also, are you using the LD_ASSUME_KERNEL "trick" with any of them? The "engine" in MusE was extensively rewritten in MusE for the 0.7 release. For me it has worked very well. Though MusE is by nature rather resource hungry... Another question is what your Jack settings are, how smull buffers are you using? I seldom use lower than 2x512 though I think 2x256 works okay too. > > > Basically I think your machine is not tuned good enough.

Indeed, I have briefly tried it a few times, but my usb hub seems extremely badly supported (or whatever the problem really is) so I had to give up of practical reasons. I'm on the jackit-devel mailinglist and there is _alot_ of talk about the reasons for the bad behaviour of 2.6. You might want to check it out the archives or read the list. > Perhaps I'll keep poking around for solutions on 2.6 and > they may be of use to others... Yep, indeed.

For the Delta 1010LT, which I did manage to get on it's own IRQ (IRQ 10) with nothing else on the buss before it, I typically run 2x512 @ 48000 khz also.

Between that and slot ordering / interrupt allocation, I've had good luck. I've also noticed that if the machine has a load on it (like when I'm compiling) less xruns happen.
