acid
by Chris McCormick 14 Aug '14

14 Aug '14

Hi, Another question in a very general vein. I asked this on the Csound list a while back (when i was using csound) with good results. I'm trying to produce an acidy type sound (eg 303) and having trouble as my current saw-tooth-through-a-vcf just sounds pretty wimpy. Any ideas on how to fatten it up a bit? I'm not looking for a perfect reproduction of the 303 sound, just a nice acid sound. Hints? Tips? Is there some place where people post interesting Pd patches they've created for others to download at try out? Should there be?

GEM trigonometry clock
by Alexandre Quessy 01 Jul '06

01 Jul '06

Hi pd-list, Just in case it might interested some of you guys, or even for the GEM official examples, I just wrote a PD clock using GEM and Zexy. It is currently available online at http://www.sourcelibre.com/puredata/clock.pd for your pleasure. It uses simple trigonometry calculations with [sin] and [cos]. Thanks !

midifile
by Martin Peach 05 Jun '06

05 Jun '06

I have posted my external for reading midi files here: http://puredata.info/Members/martinrp There is code and a compiled dll for windoze as well as a shell script to compile it for lignux, and a help patch. Should work on OSX too with slight changes (define _BIG_ENDIAN for ppc). Midifile reads type 0 and 1 SMF (.mid) files and may work on type 2; it should ignore any non-standard meta codes. Please let me know how you got it to crash ;) Write functionality may be forthcoming in a few weeks... Martin

display waveform in GEM
by derek holzer 27 Feb '06

27 Feb '06

Following an idea from Gerhard Daurer, I'd like to look into displaying the waveform of an audiofile in a Gemwin. Gerhard sent me a prototype of a very cool patch combining my Particle Chamber with PMPD and GEM, which uses physical modelling to visually control the granulation of a soundfile. (And I hope he posts this same prototype here soon!) In his version, he has only a set number of audiofiles to choose from, so he simply loads a JPG of the waveform into the Gemwin. However, I'd like to be able to load any wav file into this and get some visual feedback (i.e. be able to see the peaks). This would be a one-time operation, and not something that would be changing in realtime (except maybe a zoom in and out), however I would like that displaying the peaks doesn't interrupt audio processing (as drawing a table would). I'd like to use GEM for this so that the various grains could be graphically represented on top of the waveform. I'm open for PDP implementations, but I don't really consider PDP cross-platform so I'd rather stick with GEM. Any Gemheads out there have an idea of how to go about this? best, d. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 82: "Honor thy error as a hidden intention"

i installed readanysf~0.13.1, but when i try to create a readanysf~ object, gives this error: <http://aug.ment.org/software/readanysf%7E0.13.1.tar.gz> /usr/lib/pd/extra/readanysf~.pd_linux: /usr/lib/pd/extra/readanysf~.pd_linux: undefined symbol: _ZN16flext_dsp_sharedC2Ev someone could help me? I use pd-0.38-4 because 0.39-0 has some midi problems. do I need upgrade? :o and flext 0.5.0

Playing with the new data structure features
by Frank Barknecht 17 Dec '05

17 Dec '05

Hallo, hm, I really like the additional features of data structures. The scaling, although a bit awkward to use or to get into, gives some nice new possibilities. Some are illustrated in attached patch. I think, one major advantage now is, that ranges can be restricted, something that came up here as a feature wish a couple of times. It could be nice to also include this for [drawnumber], which currently doesn't work. Also thanks to the scaling it now is possible to have "inverted" ranges, which as in attached slider example often is more natural to use. Switchable visibility can be used for nice effects, too, and might be useful in conjunction with the new selection feature as well. Visibility switching however doesn't work correctly with [drawnumber] yet, which can be demonstrated by adding a "-v vis" to the [drawnumber ...] instruction in the slider template: Numbers don't get deleted correctly, when their visibility is switched off. I didn't yet play a lot with the selection feature yet, apart from looking through the help and example patches. It also looks immensly useful, because it provides a kind of callback on editing operations through the pointer sent by the [struct]. However the current mechanism doesn't allow one thing, that could be useful as well: If I change the value of some graph, while I'm not in edit mode, there still is no direct feedback. OTOH when I'm in edit mode, I can select an object and get this feedback, but I cannot change its data fields unless I leave edit mode again. With all this, I see that I can make a lot of cool enhancements to my msd-editor, which unfortunatly have to wait another week. ;) Ciao -- Frank Barknecht _ ______footils.org__ _ __latest track: "plak" @ http://footils.org/cms/show/44

feature extraction
by Jacob Last 28 Nov '05

28 Nov '05

Hi all-- I'm currently working on a project for controlling my granular synth patch using a control stream derived from various feature extractions from an input signal (soundfile or live). Currently what I'm working with is the spectral centroid, which I've implemented as a PD patch. I'm wonding if people have other ideas for perceptual features that can be reliably extracted from an audio stream using the FFT or otherwise. The input is not necessarily pitched (might eventually want to analyze its own granular output as well, in addition to noisy and unpitched sounds) so I'm not that interested in pitch tracking, etc. rather more high level sonic features. For example, how might I detect a period of sharp attacks on a wind instrument? Maybe by using some sort of peak threshold with the spectral centroid? "Smoothness" of a sound? Continuum of pitched to unpitched? Etc. Also if there are any PD implementations (abstractions or externals) of this sort of stuff please inform me; I haven't found anything as of yet. I'd very much appreciate any input! Best, Jacob
