patches/abstractions? [was: Berlin workshop]
by Kevin McCoy 28 Mar '07

28 Mar '07

Hi Derek, I was wondering if you had gotten a chance to share any of those patches you used for this workshop? I hope I'm not pestering you by asking, and certainly no pressure - it just sounded like a really good time! I would love to hear the kind of stuff you guys were working with - I've never seen any patches that dealt with feedback manipulation yet besides my own little half hearted attempts :) thanks Kevin -- ++++ http://pocketkm.blogspot.com

ANN: pdmtl abstractions library 1.0
by Alexandre Quessy 27 Mar '07

27 Mar '07

Hi all, The Pure Data Montréal Abstractions library 1.0 is out ! Try it while it is fresh. ;) See http://wiki.dataflow.ws/PdMtlAbstractions for download and install informations. It is in the process of being added to pd-extended build system. It is currently under abstractions/pdmtl in the Pd CVS. Many thanks to http://goto10.org for the subversion development server which we use. (WARNING : the structure, name and usage of these abstractions are very likely to change in the next versions) The main concept in this library of abstractions is to group the abstractions by their function rather than their author. It is an answer to the disorder in the large amount of abstractions and externals for Pure Data. We propose this organic classification system as a solution for reorganizing the huge mass of code in the Pd externals and abstractions. See http://puredata.info/dev/PdLibraries for a discussion around this topic. The library also proposes methods for unifying the usage of GOP (graph-on-parent), audio samples and much more. It is also intended as a wrapper for very useful externals for Pd that are often named badly or not well know. Pure Data (see http://puredata.info/ ) is designed to offer a wide range of low level objects. That is why we believe that higher level abstractions must be created and standardized for their use by beginners and advanced users as well. This accelerates the learning curve and makes it very fun and fast to use. The algorithms are hidden in the abstractions but are still very easy to read, as an abstraction can be opened and modified. The library contains abstractions of Thomas O. Fredericks (such as the sample_id format), Alexandre Quessy (such as the Muzaq musical abstractions) and Patrick S. Coulombe (the Lem ongoing audio patches). Even if the library uses the name "Montreal", it is open to the participation of people from anywhere and could even aim to become the standard format for Pd externals and abstractions names, avoiding name clashes and users' confusion. See the discussions on http://puredata.info/dev/PdLibraries to understand a bit further how this represents our suggestion as a solution for the organization of the Pure Data extensions. Any comments, patch contributions, threats or congratulations are welcome ! -- Alexandre Quessy http://alexandre.quessy.net

multiple karplus-strong delays causing system to max out
by David McCarthy 27 Mar '07

27 Mar '07

Dear List, I am trying to run 40 karplus-strong delays, 20ms max long each, using vd~ and delwrite~ with the (filter~ bpq $1 $2 1 1) modulating. My system is a 1.2GHz Athlon Win98SE 700MB Ram. Perhaps it cannot deal with 0.99999 as the coefficient within each infinite loop? Maybe I should put the volume before the delay loop, as opposed to after? Maybe I could use the xsample objects? My processor starts off ok, and after about 1 min, it hits 100% and stays there! Help much appreciated! David.

Re: [PD] [PD-dev] Makefile with recursive directories
by Charles Henry 27 Mar '07

27 Mar '07

I think there's an easier way to do directory recursion in makefiles, just using the export command (which sets variables globally, accessible to all shell scripts). So, if you have a top-level makefile, which sets variables according to a makefile.in, you can export those variables. Then, build a makefile in each subdirectory. something like: export VARS; cd pdmtl; make; and then you have another makefile in the pdmtl dir, which does the same thing for each subdirectory below it, with only the lowest level makefiles actually doing the installation. I'm pretty sure that I've seen this used before for makefiles (and I haven't tried it myself). It's not automatic... (which is your actual question--I'm not sure about that) Chuck

[sqosc~]-issues
by Roman Haefeli 26 Mar '07

26 Mar '07

hm.. it seems that the previous mail wasn't sent.... here again: hello martin peach i tested your external a bit more deep on the 'good' soundcard, where i can exclude aliasing introduced by the soundcard. it turned out, that a bit of aliasing is audible in the range above 5000Hz. i think this is not tooo bad, maybe for 'pure'ists. but i had serious troubles, when loading some patches, that contain [sqosc~]. it can happen, that after loading the patch, pd is sending constantly a dc to my soundcard. even when i close pd, the dc stays on these channels, where pd was connected before over jack. to get rid of the dc, i must restart jackd again. because of that, i assume it is related to jackd (is it possible to crash jackd from pd?). i attached a test-patch. when loading that patch, jackd (and pd) get unusable for sure. my system: ubuntu dapper i386 pd-0.40.2 jackd 0.100.0 when i create a patch from scratch with [sqosc~], i have no troubles. i get the dc also, when i open the help-patch of [sqosc~]. roman ___________________________________________________________ Der frühe Vogel fängt den Wurm.

TWAIN - scanner - pd
by Jiri Heitlager | dadata.org 26 Mar '07

26 Mar '07

I am in the process of planning a new project that involves the use of a scanner. Somehow I need to read the data that the scanner is sending over the USB port into PD. Is something like this allready done so I could have an example? So far I only came acrosse the SANE project a JAVA lib. called Morena and ofcourse TWAIN. I assume that nobody is going to hand me a ready made code, so I am thinking how I should aproach this. Here's how I think the basic should be like. 1) make an JAVA app that reads in the scanner data (continously, lamp should always be on!) 2) format the data into OSC and send it via UDP 3) set PD up to listen to a specific port. I would really appreciate some feedback so I can continue in the right direction. Thank you, Jiri
