ok thisis a little OT, but what DATA RATE are folks using for smooth playing movies? I recall from the installation i was running a G5, with like 4- 8GB movies playing very smoothly on my laptop of course is a bit stuttery. i have been dumping out of final cut as DV-NTSC Sorenson3 lets me tweal Data Rate but at picture cost. any tips or hints?

beginner's MIDI routing questions
by Ryan Supak 04 Oct '04

04 Oct '04

Hi, I'm trying to use PD as a MIDI routing tool -- I was using MIDIOX but I want to go a little more in-depth. Right now I'm still trying to learn the basics. I'm currently playing with the ~notein and ~ctlin objects, and apparently the ~notein is aware of note number, velocity, and midi input number -- and the ~ctlin is aware of ctrl number, ctrl value, and midi input number. 1) what's the best way to determine the midi channel of incoming data (and ultimately to output the data stream as a certain midi channel)? 2) I used pd -midiindev x,y to tell pd which midi inputs I wanted. MIDI input 1 is showing up as "1", according to ~notein and ~ctlin, but MIDI input 2 is showing up as "17" or "20" (depending on the parameter used). 3) Is it possible to send Program Change messages with PD? Any input would be appreciated on either count!! rs

zexy compile error AMD 64
by thewade 04 Oct '04

04 Oct '04

I reported earlier about problems compiling zexy on my AMD 64 laptop. I solved my own problem. I added -fPIC to the CFLAGS in src/makefile I also added to the all: ld portion and the final linking in .c.pd.linux but I dont think thoes were necessary. Just in case anyone else has had this problem. -thewade

> midi is I think independent from jack. if you use alsa be sure you have > snd-rawmidi and the oss compatibility layer loaded as driver my .config kernel config file has: CONFIG_SND_RAWMIDI=y CONFIG_SND_OSSEMUL=y It has to be a driver (module) and not compiled into the kernel? Could this have something to do with hdspmixer not working (e.g. does hdspmixer make the midi interface available)? > can you use MIDI with other software ? I dont know, is there some way from the command line to send midi signals out /dev/midi(x)? Is that even the interface for the hammerfall? At this point all I have is PD (and gem). I may install audacity later, but I do all my final mixdown (for recordings) on my windows box. I think your right, with regard to midi and jack being seperate. My old laptop was able to use both jack and hdsp midi with pd... weird. Thanks for the help! -thewade

hi miller, I'm not sure if this has been reported before but I found the following in pd-0.38 and earlier versions: If you try to change the font size of patches with subpatches and not all successive ones in the hierarchy are visible pd crashes. example patch is attached. take care, x p.s.: I also changed the spigot help file according to the diff I sent it's here -> http://test.pilot.fm/pd/misc/ -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

International Linux Audio Conference 2005 (LAC05): Call for Papers and more
by Frank Barknecht 04 Oct '04

04 Oct '04

Hi Pd'ers after the highly successfull pdconv in Graz I'd like to invite everyone of you working or intending to work with Linux to consider joining the Linux Audio Conference III in Karlsruhe next year, April 21st-24th. It's a great place to be and would be a wonderful chance to meet again and do the usual coding, patching, dancing and drinking stuff. -- Frank Barknecht ----- Forwarded message from Frank NEUMANN <frank.neumann(a)st.com> ----- Date: Sat, 2 Oct 2004 14:25:32 +0200 From: Frank NEUMANN <frank.neumann(a)st.com> To: linux-audio-dev(a)music.columbia.edu Cc: lac2005(a)zkm.de Subject: [linux-audio-dev] International Linux Audio Conference 2005 (LAC05): Call for Papers and more Hi list, as had been announced here earlier, the 3rd International Linux Audio Conference (or "LAC05" for short) will take place on April 21st-24th, 2005, again at the ZKM (Zentrum fuer Kunst und Medientechnologie, Center for Arts and Media Technology) in Karlsruhe, Germany. The organizers are now happy to send out the Call for Papers, Call for Music and more. We have prepared a web site containing all the details, including the text of the Calls, submission instructions, mailing list/contact addresses and more here: http://www.zkm.de/lac The website is not fully equipped yet (e.g., the templates for Papers have not been finished, and registration is not yet possible), but this will be added in the next weeks. Please watch the "News" page for up to date information. Compared to the last 2 years, we have changed several points. With the conference growing both in numbers of talks and visitors, certain things need to be planned more precisely in advance. That is why we now have a review process for papers and mandatory registration (as well as some other smaller changes, see the web page for details). We hope that you will agree that this is only for the better. We hope for a lot of interesting and entertaining papers and talks, and look forward to meet you (again :-) in April 2005. One detail we can reveal already now is that we could "hire" Fernando Lopez-Lezcano to hold the keynote. If you know of other interested parties - local user groups, composers, other mailing lists or individuals - please forward this mail wherever appropriate. If you have any kind of questions about the conference or this call, please don't hesitate to contact us at: lac2005 _at_ zkm _dot_ de. Thanks for reading, The LAC05 organization team: Goetz Dipper (ZKM) Matthias Nagorni Frank Neumann -------------------------------------------------------------------------- LAC 2005 Calls ============== Call for Papers --------------- We invite submissions of papers addressing all areas of audio processing based on Linux and open source software. Papers can focus on technical, artistic or scientific issues and can target developers or users. This includes (but is not limited to) the following categories: * Computer Music * Music Production * Instruments * Drivers and Sound Architecture * Audio Distributions * Generic (Usage, Documentation etc.) The conference is held in English. In contrast to the last conferences we are asking you to submit elaborated papers rather than abstracts only, for the following reasons: * We are planning to publish conference proceedings (in print and online) and a conference CD. * Also, the conference has grown to such an extent that we have to limit the number of talks. All papers will be reviewed by a board of experts. Based on their recommendations the organization team will decide which talks will be accepted. If you want to present some work in progress rather than a complete paper, please consider the sections "Call for Project Notes" and "Call for Posters". Length of a paper is 4-8 pages. Papers should include an abstract (50-100 words). The abstract will be published separately on the conference website once the paper has been accepted. Also, papers should include up to 5 keywords. We are going to use these keywords to create an index of the proceedings. In general talks should take 20-30 minutes followed by 5 minutes discussion. If you think you need more time, please tell us. Please also notify us if you need a special technical setup. The technical standard setup will be: * microphone (head set) * projector with XVGA input (resolution 1024x768) * stereo speaker setup with mini jack input If you are not able to bring your laptop along with you, please notify us in advance. How to submit * File format is PDF. If you cannot produce PDF, contact us. Make use of the templates for paper formatting available at the web page. If this is not possible, please contact us. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your paper and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * You will be notified by 18 Feb 2005 whether your paper has been accepted. The reviewers may ask you to modify your paper in order to be accepted. The deadline for the final version is March 11, 2005. Important Dates 10 Jan 2005: Paper submission deadline 18 Feb 2005: Notification of acceptance 11 Mar 2005: Final version deadline 21 - 24 Apr 2005: Conference Call for Project Notes ---------------------- A project note is very similar to a paper, but does not need to be as elaborated and complete. Length of a project note is 2-4 pages. Project notes should include an abstract (50-100 words) and up to 5 keywords. In all other respects, the same criteria apply as for papers (see section "Call for Papers"). How to submit * File format is PDF. If you cannot produce PDF, contact us. Make use of the templates for paper formatting available at the web page. If this is not possible, please contact us. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your project note and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * You will be notified by 18 Feb 2005 whether your project note has been accepted. The reviewers may ask you to modify your project note in order to be accepted. The deadline for the final version is 11 Mar 2005. Important Dates * See dates for "Call for Papers" Call for Posters ---------------- With respect to their content poster presentations do not differ from regular talks: Posters can focus on technical, artistic or scientific issues and can target developers or users. See section "Call for Papers" for more info on this. Since we never had poster sessions up to now, here is a short description of what we are planning: Authors will bring a printed poster to be attached to a wall. There will be enough space to have about 10 posters presented simultaneously. Authors are expected to present their posters by short presentations (max 10 min), which they repeat several times during the whole poster session. A whole poster session will take 2 hours. People can walk around and freely choose which poster presentation to attend and can visit several presentations during the whole poster session. Two reasons why we decided to include poster sessions into the conference: * We can have more presentations in the same time * It allows for more "interactivity" with the audience Note: It is not planned that you use your laptop while presenting the poster. The poster will not be part of the conference proceedings. However you may additionally provide a paper or project note on your topic which will be included in the proceedings. See the section "Call for Papers" for more info (especially about the paper templates). The poster itself will be included on the conference CD and on the conference website. How to submit * File format is PDF. If you cannot produce PDF, contact us. There is no template for posters. * Add a separate abstract (ca 50-100 words). The abstract will be published on the conference website once the poster has been accepted. * Add a separate list of up to 5 keywords describing your poster. We are going to use these keywords to create an index for the conference CD and online. * See our check list to ensure that you do not forget to enclose all necessary information. * Send your poster and all necessary information until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * All submissions will be reviewed by a board of experts. See section "Call for Papers" for more info on this. Important Dates * See dates for "Call for Papers" Call for Workshops/Tutorials ---------------------------- With respect to their content workshops do not differ from talks: Workshops can have technical focus as well as artistic or scientific focus. Workshops can be targeted to developers as well as users. See section "Call for Papers" for more info on this. Workshops will take place in seminar rooms. Attendance is limited to ca. 10 people. A workshop can take significantly longer than a talk (2-3 hours). We have already had workshops during the last conferences, but most of them were rather spontaneously initiated. We will still retain the possibility of spontaneous workshops, but additionally we would like to encourage people to submit carefully prepared workshops. You might submit a paper along with your workshop proposal. If accepted, the paper will be included in the conference proceedings. Make use of the paper templates (see section "Call for Papers"). How to submit * See our check list to ensure that you do not forget to enclose all necessary information. * Send an abstract (ca. 50-100 words), all necessary information and your (optional) paper until 10 Jan 2005 via email to this address: lac2005 at zkm dot de * The abstract will be published on the conference website once the workshop has been accepted. * All submissions will be reviewed by a board of experts. See section "Call for Papers") for more info on this. Important Dates * See dates for "Call for Papers" Call for BOFS ------------- "Birds Of a Feather Sessions" - among all the events during the conference, the BOFS will be the most spontaneous. So there is no deadline for BOFS submissions. A BOFS is a chance for like-minded users and/or developers to exchange experience and knowledge about a specific topic. This can happen in a public place like the ZKM cafe or in a seminar room (if available). If you like to suggest a topic for a BOFS, do not hesitate. Send an email to lac2005 at zkm dot de, include an abstract (50-100 words), a title for the BOFS, and possibly additional remarks. Call for Music -------------- There will be again some concerts during the conference. We are looking for music that has been produced completely or mostly under Linux and/or with open source software: * Interesting demos of sound synthesis, sound processing, etc. This should include a short talk/introduction to the technique used. * "Serious" compositions, to be played in a concert-like context * Electronica, Chill-Out, Ambient etc. If you want to participate, send your composition(s) to this address: Linux Sound Night ZKM | Institut fuer Musik und Akustik Lorenzstr. 19 D-76135 Karlsruhe Germany Make use of one of the following media formats: * Media: Audio-CD, DVD or CD-ROM * File formats: aiff or wav * Channels: mono, stereo or multi-channel * Samplerate: 44.1 or 48 kHz * Resolution: 16 or 24 bit Include the following items with your submission (in English): * Requirements (speaker setup, instruments etc.) * A filled-in and signed printout of the form available on the web. For the printed programme and to be published online and on the conference CD, in continuous text (no table or list please): * A short commentary on the compositions (ca. 150 words) * A short Curriculum Vitae (ca. 100 words) Deadline for submissions is 10 Jan 2005. A jury will select the compositions that will be performed/played. Furthermore, the jury will give out 3 prices to participants to contribute to their travel expenses. Besides artistic criteria and technical reasons, these criteria apply for the selection: * Tape pieces or pieces which are performed by the composer herself will generally have more chances to get included. * If we get more pieces than we can include in the programme, composers who are attending the conference are preferred. Terms and conditions for participation can be found in the form mentioned above. This form includes among other things: * I will receive no fees whether my composition is played or not. * GEMA fees (in case of performance) will be paid by ZKM. * The material I send to ZKM will not be returned. Additionally to this Call for Music, there will be an open stage called "Plug & Chill - The Linux Jam Night" at Saturday night (23 Apr 2005), where attendents of the conference are invited to perform their pieces in a less "official" context. There is no deadline for this, so people can decide during the conference if they want to participate. However if you already know that you want to participate, do not hesitate to inform us. Send us an email to lac2005 at zkm dot de and include a description of your equipment and a short characterisation of your music (keywords only). During the conference it is possible to register at the info desk. Note that there is a time limit for "Plug & Chill". If we have received too many registrations already you might not get a slot. Contributions to "Plug & Chill" should not exceed 10 min. There will be a room at ZKM where people can meet during the conference and rehearse for "Plug & Chill". ----- End forwarded message -----
