Re: [PD] pd latency on puredyne 9.10 with Nvidia HDA
Well with the stock install of Ubuntu studio 10.10 except for the graphics accelerator upgrade the audio was still glitching the same as with 9.10 puredyne. So I done all the upgrades possible and that seemed to get the patch running without gem with a 50ms buffer. There is no glitching while messing with the guis in pure data like there is in 9.10 so I'm guessing it's either a window drawing routine or something to do with alsa or the audio codecs that got upgraded. Now maybe I can figure out how to tinker with the alsa drivers to lower the latency.

This is without GEM I will try this same thing with the same patch in Uuntu Studio 10.10. Earlier I noticed from puredyne that whenever the audio glitches the cpu% jumps to 1% instead of 0 for soundcard IRQ process. I tried setting the priority of pd and pdgui to -10 and this seemed to help a bit. Maybe I need to adjust the buffers for ALSA to match the buffers of ASIO for ALL. which is set at 512bytes with a buffer offset of 4ms.

Re: [PD] help browser resize + guiplugins organization
Hi Hans, Hans-Christoph Steiner wrote: Well, the horizontal resizing behaves weirdly too, adding a bunch of padding that is totally unnecessary, for example. Yes, I fixed it already (with a separate pack for the listbox and the scrollbar). However on my computer, if I manually resize the window horizontally, the window does not automaticaly fit to the number of listboxes anymore. That makes sense, since tk can't decide whever the width is for the window or for the number of columns currently displayed. Forcing the horizontal size back to the initial one could be frustrating too. Adding an horizontal scrollbar sucks (sounds like OSX Finder). I think I can come up with an in-between solution, such as when horizontally resizing, decide each new panel will have the width of (window hsize / displayed listboxes). I'm also working on this: # TODO enter and up/down/left/right arrow key bindings for nav In the meantime, I submitted a very short patch that just unlocks the size. -- Charlot ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] pd latency on puredyne 9.10 with Nvidia HDA
Sounds like you have an interesting problem with your nvidia sound device. Is the audio device a part of a graphic card by any chance? Sounds like the graphics is interferring with the audio device, though on puredyne the rtirq-init script together with the realtime kernel should give higher priority to the audio device even when sharing irq with other devices, if this is the source of your problem. Perhaps Alsa would be interested to know of this problem? You could subscribe to their mail list and let them know.

Congrats, you have a fast computer (and perhaps a cache of configure-results too). in my experience, the thing that takes most of the time when building Gem is running autoreconf. since i cannot imagine what you would do to re-trigger a full run of autoreconf, any subsequent builds should be much faster. I don't know... if I installed a library that I found out was missing, what else can I do, apart from ./configure again ? if you re-run configure and change some options, only a few files will be rebuilt. (all those that include config.h, which are about 29 .cpp files of 597) Well, most of the time, what I need to change in the conf, is what a configure-script did not detect, and needs to be detecting now. Can I skip autoreconf in that case ? but doing make seems to be redoing much of the work that ./configure does anyway. and [pix_artoolkit] has it's own configure script anyhow, so you would only need to configure and build a single file. But did you read at all what the problem was ? I didn't get any [pix_video] support, so I wasn't able to test whether the [pix_artoolkit] really worked. btw, in a way this reminds me, why i couldn't use GF for ages: after 5 minutes of compiling, it would freeze my computer. after changing my motherboard, i was finally able to build it.

[PD] List delete carnage - 2 questions
Hey all, I'm stuck. I have a sensor which is spitting out numbers between 1-180. Each number triggers an event that I only want to happen once but the sensor repeats numbers every so often. What I require is to have my numbers in 'something', so that if that number has already been used I want Pd to say - 'hey' and then allow me to change that number until we find one that hasn't been used? I have spent the last couple of hours working with my numbers in a message box and using [list-delete]. I think it must be my usage because it's behaving very erratically (patch attached). If someone could tell me what I'm doing wrong with this and then maybe I/we can get onto the main problem - which is; what should/can I use that will tell me if a number has already been used and spit it back at me so I can do some maths stuff to change to a different number that hasn't been used already.

Re: [PD] pd latency on puredyne 9.10 with Nvidia HDA
If the device is not sharing irq with another device, then there should be no problems in that regard. Haven't ever heard of your symptoms. On Linux, if you use jack, PD's ms setting won't make any difference on audio, only midi. I wouldn't use any lower setting on PD than the lowest you would use with jack. To avoid glitches with jack, try using a high frames/period. Also, make sure you are realtime capable, which should already be prepared on Puredyne. Could be someone already had you're problem and discussed it on another mail list. Alsa would be my strongest bet.

You can use a table of 180 elements, each of which is initialized with zeros. When a sensor number occurs, check against the table. If it's 0, turn it to 1 and go on. If it's 1, do nothing and wait for a fresh number from the sensor. Or, if you don't want to wait, scan the table for the first zero. What appends when there's no zeros left is up to you.

In custom of the previous conventions we invite you to submit your papers related to the Pure Data programming environment in the fields of computer science, artistic creation and scientific research. The papers will be rated according to academic standards such as novelty and relevance in a peer review process. The Pd community is a heterogeneous group of users, developers, authors, artists, musicians, programmers; often in more than one role at a time. Papers from widely divergent perspectives are encouraged. Some possible topics could include: • Libraries and externals extending Pd • Tools built in or for Pd • Education • Spatialisation • Pd on mobile devices • Pd embedded in games and applications • Pd as a framework for audiovisual works Please check the website for the of terms of submission. Templates for the Papers (LaTeX, Open/LibreOffice) will be provided soon on the conventions home page: http://www.uni-weimar.de/medien/wiki/Pure_Data_convention_2011 The conference is held in English, thereby the papers have to be in English. The length of a paper should be 4-8 pages, including an abstract (50-100 words) and up to 5 keywords. Proposals for workshops of all levels, from beginner to special interest, may be directed my email to max.neupert at the domain uni-weimar.de A separate call for music, performances and artworks will follow soon.
