Re: [PD] Am I alone?

That's a pretty pompous writeup. Why don't you just post a link to your work instead of making broad generalizations about other un-specified material? Ben Baker-Smith -- http://bitsynthesis.com

beat onset detector (in style von recycle)?
by João Pais 24 Mar '11

24 Mar '11

Hi, I wanted to ask if someone works/worked with beat detection in style of recycle. That is, a patch that can analyse assymetric audio files (I mean, files with "improvised" content), and suggest mark points to where attacks can happen. Afaik, there is no external that does this automatically, right?

I've also tried with "auto 1", with and without the bangs, and nothing changes.

Successfully building Pd-extended-0.42.5 on Debian Wheezy amd64
by Lorenzo Sutton 24 Mar '11

This might be of interest to someone. I tried to summarise the steps here: http://puredata.hurleur.com/viewtopic.php?pid=23199#p23199 Lorenzo. PS. As said pretty much untested but everything seems to work.

Re: [PD] overriding objects
by Jonathan Wilkes 24 Mar '11

24 Mar '11

Sorry, I wasn't being specific-- I'm talking about what happens with [import ekext] or [import pddp]. Aren't these are both examples of "loading a library?" While it's true [import ekext/polymap] or [declare -lib ekext/polymap] display the console message for [polymap] (the former upon creation and the latter when the patch is opened), that message is only printed once; same for your example below. Iohannes seemed to be implying that a gf.print console message would be a nuisance because the message would get printed for every object used in the patch (minus one, apparently): "so if you load a patch with 87 [print]'s in there, what information do you get if Pd prints 86 times 'dear user\, you are using matju's special [print]\, which has problems with parens.'" I don't see how such repeated messages would ever happen-- do you? My main point is that I think it's a good idea that if an object takes over a vanilla object, the user has some way to know-- for example, to report bugs more effectively. There are plenty of externals that print informative console messages so I don't see why there would be an issue in this case. -Jonathan From: Frank Barknecht <fbar(a)footils.org> To: pd-list(a)iem.at Sent: Wed, June 16, 2010 2:24:13 AM Subject: Re: [PD] overriding objects On Tue, Jun 15, 2010 at 11:46:53AM -0700, Jonathan Wilkes wrote: > Oh, I see, I didn't check about expr.

In pd-extended lingo, the term "loading a library" has been misused to also mean setting a couple of "-path"s. The traditional use of the term describes what happens when you use the "-lib" flag or [declare -lib ...]. polymap prints its message, when it's loaded like that: $ pd -lib polymap ... |. . . . . . . . .polymap. . . . . . . . .| |_- polyphonic chain reaction regulator -_| | . . . . . .Edward Kelly 2006. . . . . . | Ciao -- Frank _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

The almighty Hardoff had done some work about this. Something can be found here http://puredata.hurleur.com/sujet-1953-sample-slicer-user-selectable-slices but I recall a quite cool patch for beatsplicing he posted to the list some time ago... like last year? Maybe the archive can tell you something more...

math + music examples
by Joe 24 Mar '11

24 Mar '11

hello i am trying to come up with some examples to use in a short workshop with 11 year old kids using maths to make sound and music (music in very loose terms that is). i would love to use pd for this. it can be literally anything, as long as they can easily see a relation between some basic math concepts (number sequences, patterns, etc.) and the sounds they hear while interacting with the patches. the goal is not to have the kids write the patches, but to make them *play* with them. does anyone have any ideas for this? useful, easy to understand math concepts that could be turned into little musical devices? any feedback will be greatly appreciated! cheerio

[part_source]
by Richie Cyngler 24 Mar '11

24 Mar '11

Hi All, [part_source]'s third inlet should take a domain according to help. I can't get any of the listed domains to work, that is, render a geo as a particle. Is this a bug? Ending the part_... chain with a [part_render] then a geo object, e.g [cube], does work, but doing it this way not all the options listed as domains, in [part_source] help, are possible because they are not all objects. Just hoping for some feedback or a solution if I'm missing something. thanks in advance -- Richie

Problems going fullscreen on external projector
by Antonio Roberts 23 Mar '11

23 Mar '11

I've made a simple video mixer in Gridflow (9.13) and I want to send the output to an external projector. I've set up my computer so that I can drag windows to the second screen, but when I attempt to go full screen using [#out sdl] and then pressing Esc it goes fullscreen on both screens. If I use an [#out window] object, which I believe is an x11 window, there's no way (that I can find) to go full screen, so I'm stuck at with an 800x600 window on a 1366x768 screen. I did attempt to use a [#scale_to (768 1366)] object to emulate being full screen but the scaling causes a massive drop in framerate. Can anyone suggest how to go fullscreen on only one screen, how to go fullscreen using an x11 window or some other way to do this? I'm using Gridflow 9.13 with Pd-extended 0.42.5 on a Dell Studio 1555 using the ATI Radeon 4555 proprietary driver running Ubuntu 10.10. Thanks, Antonio

64 channel MADI HDSP
by mercer b. (bm7v07) 23 Mar '11

23 Mar '11

Hi there, I am trying to get pure data outputting 40 channels using 64 channel RME HDSP-MADI. With little success so far... I can only get two channels working at a time whilst using ASIO and only 8 whilst using the standard driver. So far I've been working in windows xp, but I am going to try linux tomorrow. From a bit of digging it seems a few people on this list use MADI with pure data. I would really appreciate some advice on how to get started using pd with MADI. Many thanks Ben Mercer Undergraduate in Acoustical Engineering Institute of Sound and Vibration Research (ISVR) University of Southampton
