hidin problem
by David Kirkpatrick 05 Apr '10

05 Apr '10

Hi, Does anyone know if there is a problem with [hidin] when using Windows 7? It seems to work initially, but then intermittently crashes the gem window after pushing buttons for a while. Using the same patch with a mouse doesn't crash. It's not a problem with the USB device I'm using as I've tested a game pad, joystick and steering wheel and pd intermittently crashes with all of them.

I wonder if it would make sense to do the same with 2 pd instances doing audio, and exchange audio between them. Maybe I could try that with Jack. But I think the latency will be doubled, because the buffers of both pd's would add up...? gr, Tim > > tim > > -- > tim(a)klingt.org > http://tim.klingt.org > > Linux is like a wigwam: no windows, no gates, apache inside, stable. >

compiling Pd-extended on Ubuntu Netbook Remix 9.10
by Ichabod 05 Apr '10

05 Apr '10

I couldn't find any Pd-extended builds for Ubuntu Netbook Remix 9.10 (is there one anywhere?), and the autobuild for Ubuntu Karmic i386 didn't work, so I tried compiling from source. I extracted the source and then cd'ed to the ~/Pd-0.41.4-extended/pd/src folder and ran autoconf and then ./configure. At that point, it gives me a bunch of "checking for..." messages and then ends with "no tcl library found." I have tcllib installed. What am I doing wrong? --Stefán

pd~ and DIO errors
by tim vets 04 Apr '10

04 Apr '10

Hi all, I have a rather heavy patch which causes DIO errors when I switch~ on several subpatches. I'm running pd + Jack on a rt kernel (ubuntu-studio Hardy),... Jack shows little or no Xruns. Now I wanted to try and optimize the patch by using [pd~]. The way I understood it is that [pd~] will start a subprocess and it will (automatically ?) divide the audio computation load over multiple processors. However, I get the impression that by using [pd~] I get the same (or even worse) results as with my regular "abstraction / [switch~]" approach; DIO error crackles. Any advice very welcome! Thanks, Tim

strange colors with pix_record

Johannes a écrit : > you can file a bug report even if it only happens on a single operating > system. I think Max implied that he wanted to submit a report as complete as possible up front. > the recording code is highly platform specific (that is: the recording > backends are platform specific), so it might well be that there is a bug > on one system not showing up on others. Yes, therefore it would also be a good idea to have a screenshot, especially one containing a correct picture and the equivalent broken picture side to side. That way, for example, someone who doesn't have the OS required to run the bug, can still fix the bug by just looking at the screenshot. But this requires an example with enough different colours... just grey is not enough. For example, this picture : http://webilus.com/wp-content/uploads/2007/11/216couleurs_du_web.jpg has more colours than one would ever need, to identify the problem, so, it's perfect for that. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

Midi device test patch?
by Pierre Massat 04 Apr '10

04 Apr '10

Hi everyone, I m going to buy a usb midi keyboard sometime soon, but i'd like to test it on my laptop first because the salesman cannot garantee that it will work in Fedora 12. The problem is that i've never used any of the midi objects in Pd. Does any of you know of a simple patch for testing midi devices? Even just a few directions to build one myself would be very helpful. Cheers! Pierre

Re: [PD] Detect silence inArray and resize
by Matteo Sisti Sette 04 Apr '10

04 Apr '10

> anyone have any idea how to do this? The first approach that comes to my mind and that I would try is: - use [env~] (or anything similar) to measure the amplitude of the signal - start a [timer] when you start recording - set TWO thresholds: one high threshold to detect when the "note" has begun (attack) and a low threshold to detect that it has finished. - Only after the signal amplitude has become greater than the HIGH threshold _and_ when it becomes again lower than the LOW threshold, then you fire the right inlet of the [timer] to measure the time passed since the beginning: you multiply by the sampling rate and you obtain the size. That is, you have to emulate the behaviour of a [threshold~] object and use its "rest" bang (see threshold help patch). Since you're probably gonna use [env~] you cannot actually use [threshold~] but it's very easy to emulate its behaviour (at least simplified as described here which is enough for this purpose). - Be sure your patch produces the size only once within the recording time (which is predetermined if i understood correctly). If you want to allow two or more fff staccato notes to be recorded in one "sample", then take the _last_ occurrence of the abovedescribed condition (one transition up the high threshold + one transition below the lower threshold); if you want to allow only one fff staccato note to be played (and suppose so), then take the _first_ occurrence. This is certainly a very simple and probably a bit naif approach, but I would give it at least a try before diving into something more complicated. Hope it helped bye m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Parallel Circuit
by Matt Barber 04 Apr '10

04 Apr '10

Hello list, I wanted to share a recent piece with you: http://ecmc.rochester.edu/mbarb/web/music.php?filter=chrono#parallel_circuit It's for saxophone quartet and Pd -- all sounds in the piece come from the sax quartet directly, from processing the saxophone sounds, or from synthesis. The piece is in four broad movements, each in four distinct sub-sections (16 total). I use four different equal temperaments in the piece as well: 12 per 2:1 19 per 3:1 24 per 2:1 14 per 3:2 (one of each per broad movement). If you listen, I hope you enjoy. Matt
