Thanks for the info Derek - this is very useful. Where do you get sarge DeMuDi? Both agnula.org and demudi.org mention woody & sid, but nothing in between. Basically, I'm trying to get a musician friend off an old Atari ST/Notator setup (which is preferable to Windows). Although problems are to be expected at the moment, it needs to be somewhat usable. I'm hoping this can work, because as a developer and an ex sound engineer it's an area I can really get my teeth into :) Darren On Sun, 2003-04-20 at 10:01, derek holzer wrote: > Darren, > > >I have a few general questions for those people using DeMuDi, > > > >- Which version are you using - woody or sid? > > > Sarge. as i mentioned in a previous email, the "official release" of > this will be in a few weeks. i was lucky enough to do a workshop with > one of the developers a week ago, so i really got a lot of the bugs out!I'm actually wondering if I've got the right apt sources () - you say your building jack, but running > > >- Is anyone using a sid IsDeMuDi over a sarge (or even woody) base Debian? > > > > is there a Sid Demudi? > > anyway, for the record, here's what i did to get it running: > > i installed Woody with the ext3 file system, then updated to Sarge, > built my own custom kernel with the low latency and preemptive patches > [don't forget the devfs and reiserfs support!], compiled my Alsa and > Jack, and got the Demudi apps. so, technically, i am only half-using > Demudi. i skipped using the kernel, although i have gotten the newest > kernel version running nicely on my laptop, there were still some issues > with it keeping its Alsa settings and such. also, some hand-tweaking is > required of the /etc/fstab to add the /dev/shm file system for the Jack. > next step is to ditch the ext3 file system and replace it with reiserfs > for smoother low latency operation, but that is beyond anything that > Demudi would do right now... > > > > >- How much software are you replacing with upstream source balls or CVSI'm actually wondering if I've got the right apt sources () - you say your building jack, but running > >versions? > > > is running > i still get Alsa and Jack from source. especially Jack, as i want to > seriously optimize it right now, so i am trying as many tweaks as i can > find in the compile. i am not sure if the Demudi Jack version is > optimized for realtime operation by users [instead of root, which > crashes the shm file system anyway under Demudi], and if it is, then it > may not be possible to use it with an ext3 file system on a 2.4.20 > kernel without lockup. if Guenter or somebody else has patched the > 2.4.20 Demudi kernel package against this, it is not a problem. but i > don't know if all this is worked out yet. > > other than that, there are almost zero sound apps which i have gotten > from upstream. many of the Demudi Sound Apps packages in the Sarge are > compiled from CVS versions [espc.
