[linux-audio-user] Help tracking down xruns

by thewade

Hello list! I am using my AMD64 with hammerfall, FC3T1, and 2.6.10-lsm and it works relitively fine (PD at approx. 10.97 ms latency) but I still get the occasional xrun. How can I track down the cause? Please help as I am somewhat at a loss how to get this machine performance stable. Thank you for your help! -thewade

[linux-audio-user] Concerning libfst, vstserver, and dssi-vst

by Dave Phillips

Greetings: Users are constantly wrestling with issues surrounding the software mentioned in the subject line, and I would like to find out what directions are planned for those projects. Here's what I see now: 1. The vstserver project is functionally dead. It cannot work with newer versions of WINE, and it appears that Kjetil does not plan to keep it updated to accommodate the new versions. Alas, this also means that his nice vsti, ladspavst, and k_vst~ projects are also unusable. :( 2. The libfst project is essentially unmaintained. Again, WINE versions wreak havoc with users who want to keep both fst and WINE up-to-date. Paul and/or Torben: Is the libfst project going to see any more activity from your end, or should it be considered an open project and up for grabs ? 3. The dssi-vst bridge is still unknown to me because of issues with RH9, and I've not had time to test it on FC3. But is there any general feeling that dssi-vst is a better route to take, at least for the normal user ? Btw, I like the DSSI API, but it seems slow in catching on with developers. Is that perception correct ? Please understand that I'm in no way criticising the work done on these projects so far. In point of fact, I'm extremely happy they exist, but I'm also in considerable doubt whether they can continue to be useful without further maintenance. Users are writing to other users to figure out how to fix small problems (usually with libfst), but these repairs are not making their way back into the codebase, which seems rather non-optimal to me. I'm also aware that the greater problems exist because of WINE's inherent instability (WRT its development, not necessarily its usability) and that Linux audio developers can't be responsible for WINE fixes too. Perhaps more crosstalk between the WINE developers and the LAD folk (similar to the recent discussion re: the kernel list and LAD) would help smooth the way for a more consistent and more manageable VST/VSTi bridge for Linux ? So, any comments or useful suggestions ? Best, dp

[linux-audio-user] stupid hydrogen question

by Paul Coccoli

I'm trying to write a drum part in hydrogen, but it needs to be in 3/4 time. I see no way to do that in version 0.9.1. The forums at www.hydrogen-music.org recommend changin the "pattern length" to achieve deifferent time signatures, but doing so doesn't have any affect. Even if that did work, I would have to triple my tempo, right? The tempo control, besides disallowing manual entry and requiring you to use the spin button (yuck), only goes up to 300. Since the song is in 112, I would need it to go up to 336, right? Or do I misunderstand what patttern length means? Any hydrogen experts out there?

[linux-audio-user] ALSA from CVS

by Mark Constable

I'm attempting to resurrect the aabuild "alsa from cvs" script but running into an issue with building alsa itself, and also unsure of "the right" method to blend in alsa from cvs with a kernel source tree. Any comments about how to improve these two functions would be appreciated and any clue as to the error when compiling alsa-lib would also go down well. setup_alsa() { cd $CVSDIR/alsa if [ ! -d ./CVS ]; then echo "Just hit the enter key at the login prompt" cvs -d ':pserver:anonymous@cvs.alsa-project.org:/cvsroot/alsa' login cvs -z3 -d ':pserver:anonymous@cvs.alsa-project.org:/cvsroot/alsa' co -P . else [ "x$(find -type d -name CVS -cmin -720)" = "x" ] && cvs up -P -d fi cd $SRCDIR rm -rf alsa/* cp -a $CVSDIR/alsa/* alsa find alsa/alsa-kernel -type d -name CVS | xargs rm -rf rm -rf alsa/alsa-kernel/oss cp -a alsa/alsa-kernel/* linux/sound cp -a alsa/alsa-kernel/include/* linux/include/sound cp -a alsa/alsa-kernel/Documentation/* linux/Documentation/sound } Are the above steps copying the the alsa-kernel parts into the linux source tree correct these days ? build_alsa() { cd $SRCDIR/alsa for i in alsa-lib alsa-utils alsa-tools alsa-firmware alsa-plugins alsa-oss do cd $SRCDIR/alsa/$i ./cvscompile done } I'm getting this error below in the first alsa-lib stage above... ...

[linux-audio-user] NoteEdit from terminal

by lachata

Hello list. I've been looking for some documentation about how to execute NoteEdit from terminal, but I don't find anything. In "man noteedit" there are some options to execute some characteristics from terminal, but it's not enough. My idea is to import a midi file and show the score. I know NoteEdit does it bye Tse3, but I woudl like to know how to do it from terminal. Does anyone have any information about commands with NoteEdit? Thank you very much.

[linux-audio-user] City Background Noise

by Spencer Russell

Hey Hey there, turns out I'm doing Sound design for a play that's going up very soon(2 run-throughs tomorrow, then we open thursday evening), and I'd love to have some ambient city noise going on throughout most of the play(it takes place in an apartment in New York City), but I'm having trouble finding what I'm looking for. Does anyone have any city sound effects? I've found lots of car horns, which is mostly what drifts up, but it's still not convincing. There's some field recordings on freesound of barcelona, but I'm still waiting for a membership confirmation email before i can download them. I'm using Ardour to record and edit the other sound effects for the show, as well as some custom circuitry to do things like make a phone ring onstage. any other linuxy sound designers out there? -spencer

Re: [linux-audio-user] Concerning libfst, vstserver, and dssi-vst

by Timo

Hi, due to the lower latency of the 2.6 kernel I have decided to upgrade to FC3. I have setup a test HDD to verify I get all my oddities working before I actually upgrade my very stable FC1 that is currently using jack_fst for VST. Here is what I've learned so far: Ndiswrapper: My SMC2802W Wifi card and Ndiswrapper work with the 8 kb stack coming by default in the Planet CCRMA 2.6.11 kernel. However, to make it work one needs the kernel sources and one needs to _compile_ the kernel, even if the binary is not used, for Ndiswrapper to compile. DSSI Works on the planet FC3 with the 2.6.11 as a synaptic update. wine-20040505 This release is the musicians friend, or at least mine. After install from rpm a link to lind d: to /media/cdrecorder is needed to make it use the CD rom. Also some configuration editing was needed in .wine/config e.g. the temp directory has to be deleted or defined. dssi-vst Does not compile with wine-200503031, 20041201 nor 20040505. No luck here. fst-1.5 Compiles, but copies libfst.so to /usr/local/lib. jack_fst expects libfst.so to be in /usr/lib, so some handy work is needed here to make it work. fst-1.6 Compiles, but install is missing a utility called mkinstalldirs which makes the installation halt. One needs either to copy the mkinstalldirs utility from fst-1.5 or then creage the requested directories by hand for this to install. The install also installs libfst.so to /usr/local/lib while jack_fst expects them to be in /usr/lib. More handywork needed. jack_fst-1.2 Requires wine-20040505 to compile. The Readme file seems to be an implementation note rather than a user document. Jack-fst needs a lot of guessing to make work. One needs the Steinberg SDK files and then one needs to edit one of the jack_fst source files by hand to make it compile. It can be done, but this is really, really ugly. I would have given up unless I would have known I was able to make it work in FC1. Native Instruments B4 organ. This VST instrument is the reason for all this trouble. I have had it working in FC1 for quite a while and I got it working last night with jack_fst and the dependencies also in FC3, which concluded my testing. Conclusions: Making VST work in Linux was very difficult. I never managed make dssi-vst vwork. None of the needed software installed without tweaking and a lot of trial and error. This took a couple of long nights for me, and I have been a Linux user for over 10 years and I have installed jack_fst once earlier. My judgement is that it is quite impossible for the average musician to make VST work under Linux. We need to fix this and lower the threshold for VST under linux. The tools are there, it is the polishing that is missing. When I have the time to update my FC1 I will document every step in notes on how to make VST work with jack_fst and publish them here for public scrutiny. br, Timo

[linux-audio-user] SC3 gtk2 terminal front-end

by Ryan Gallagher

I'm resuming my exploration of SC3 ( http://supercollider.sourceforge.net/ ) and my strong aversion to emacs has led me to search for a useful gtk2 frontend for sclang. ggap ( http://ggap.sourceforge.net/ ) seems to be 99% ready for use. http://ruinaudio.com/files/ggap_sc3.png The author is very nice and has generously considered adding some SC3 specific features. I'm absolutely NOT the person to come up with a list of features, but since I got the ball rolling I put together a intro to SC3, and a list of SC3 features that are commensurate with the goals of ggap. http://ruinaudio.com/files/ggap_ideas.txt If any experienced SC3 users are interested in sharing thoughts about what features might be useful please visit the ggap page, or email me, or drop by #ggap on freenode. thanks, -ry -- Ryan Gallagher <ruinaudio(a)comcast.net>
