Id' like to kwow if there is a way to select or zoom into a particular spot of the video. Or Maybe is there a solution to fragment the video into several pieces?! Danny Perreault

RRADical WIP collection
by Frank Barknecht 12 Jan '04

12 Jan '04

Hi all, here's a work in progress collection of the state of affairs in RRADical Pd as I propose it. http://footils.org/pkg/rradical-wip-040109.tgz This includes a new and improved version of the pattern sequencer rrad.pattseq and memento and lots of more abstractions for reuseability enhancements in Pd. Impressive Screenshot of a use case is here: http://footils.org/images/rradical-wip.png Extensive documentation is missing. :( I'll regularily announce updates to my wip-collection here: http://footils.org/cms/pydiddy/wiki/RradicalPd Linux-audio-user is CC'd because maybe this is interesting to, well, Linux audio users, too, I guess. == What is RRADical Pd? == One goal of RRADicalPd? is to create a collection of patches, that make Pd easier and faster to use for people who are more comfortable with software like Reason or Reaktor. RRADical ships with patches, that solve real-world problems on a higher level of abstraction than the standard Pd objects do. All these high level abstractions (should) come with (detachable and changable) GUIs built in and use a common way of saving states. They also include a net remote control using OSC. RRAD as an acronym stands for "Reusable and Rapid Application/Audio Development" with Pd. The official home of RRADical Pd is: http://pure-data.org/community/projects/rradical/ Have fun, -- Frank Barknecht _ ______footils.org__

> many bug fixes for audio and MIDI I/O on various platforms. cool, the maudio quattro is working through the oss layer again !!! if /dev/dsp0 is your quattro, create a symlink from /dev/adsp0 to /dev/dsp1 ... then you can start pd with -audiodev 1,2 and you'll be able to access all 4 channels in and out ... better than frank's alsa hack ;-) Tim mailto:TimBlechmann@gmx.de ICQ: 96771783 -- The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn, like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!"

compiling flext and pool on OS X
by Matthew Nish-Lapidus 11 Jan '04

11 Jan '04

Hi, I'm trying to compile flext and pool on OS X 10.3 but I'm running into some errors. After I edit my config-pd-darwin.txt i get this error on compile for flext: build-pd-darwin.sh: line 28: -malign-power: command not found g++ -c -dynamic -O2 -DFLEXT_SYS=2 -DFLEXT_USE_SIMD -malign-power -maltivec -faltivec -I/Applications/pd/pd-0.37-0/src -I./source source/flbase.cpp -o pd-darwin/flbase.o /var/tmp//cc6mY9Y2.s:unknown:FATAL:can't create output file: pd-darwin/flbase.o make: *** [pd-darwin/flbase.o] Error 1 Any idea what i should do to fix this? I'm not even trying to compile pool until I get this sorted out. I want to be able to use and develop RRAD abstractions, so I really need to get this stuff working. Thanks for any help. /* Matt Nish-Lapidus www.ekran.org/mn-l matt(a)ekran.org // mattn-l(a)rogers.com "What's this fish doing in my ear?" */

Performance Drop at 35 simultaneous [tabplay~]
by Dan Wilken 11 Jan '04

11 Jan '04

List, I have a patch, it records an event into an array event(x), when recording is stopped, it crops the array to the recorded sample size and starts a playback [tabplay~ event(x)] -- [bang] [tabplay~] loop. Then we record the second event, until track 200 or so. I was expecting to have to use 2 or three machines, but on my G4 350 I'm starting to have hickups around 35 tracks in. It performs up to 90 tracks, my current beta, but not well. How can I improve things. I've used tabplay~ because it's supposed to be cheaper than tabplay4~, correct? Can (and should) both my recording and playback be down-sampled from default 44.1? Is there any way to change the 32 bit floating point in PD to 16 bit? Would this help? I used renice to bump pd up to level -19 and Wish to level -17, I think that helped a bit. Does tabplay have an invisible trigger? I haven't tried no gui yet, will do so next. Will it help? Any ways to allocate more memory? Where does PD store my arrays? RAM or Hard Drive. The patch currently does not do any writing to or reading from disk, though I imagine it may have to, especially for crash recovery and/or network load sharing. Tips for both Linux and OS X Welcome. Is there a good "optimize system for PD" howto out there? Is Panther working better with 0.37 than Jaguar? I'm running Jaguar, though happy to switch if it's encouraged. A little off topic, but At random points, I get 90 "~error: tabplay~: event0: no such array"s The arrays don't exist, at least not called event0. The arrays are created at setup time to reduce load during performance, but the [tabplay~]s are renamed only when triggered. There is nothing that I can see that's triggering these [tabplay~]s, they're all hidden behind a [route] and by definition only fire off one at a time, and named at that point. Does tabplay have an invisible trigger? This must be costing me CPU time. This happens whenever I close a subpatch, every time I start and stop the tabwrite~. Thanks in advance, Dan

Yes, put (load "/path/cm.scm") in the top of "global.scm" and rebuild k_guile. By the way, perhaps it would be a good idea if global.scm did something like " (load-if-exists "/etc/.k_guile.scm") (load-if-exists "$HOME/.k_guile.scm") " as one of its first operation? --

slightly obvious PiDipd install issues under OSX
by Michael Podolak 11 Jan '04

11 Jan '04

Hello- Considering I am slightly new to OSX, I was trying to install Pidip through Fink Commander during the past few days and ran into a bit of a problem... Using Han's installer package I managed to put my Pd folder in my home directory where I bring the application forth through Terminal with the command line "~/pd/bin/pd" However, it seems like Pidip wants Pd to be in ---------" /usr/local/lib/pd/ ,so that I can put PidipD in /usr/local/lib/pd/pdp_pidip_osx " Where is the /usr/local/lib directory and how do I move Pd to if it is hidden? I was also instructed to perform the following: ---------"Modify your .pdrc file " by adding the lines: -path /usr/local/lib/pd/pdp_pidip_osx/abstractions -path /usr/local/lib/pd/extra:/usr/local/lib/pd/pdp_pidip_osx/abstractions -lib /usr/local/lib/pd/pdp_pidip_osx/pdp Remember .pdrc is a hidden file and should be located in your /home/ folder if it is not there make one yourself. I tried typing in these lines in Terminal and X11 to no avail... Should this be done elsewhere in a different fashion? what exactly does this mean? Thank you for the help, Podolakmichael
