abstraction helppath
by Peter Plessas 15 Jun '07

15 Jun '07

Hi! i wrote an abstraction and put it into a subfolder (named 'pp') inside my 'abs' folder. Pd's path points to that 'abs' folder. Loading the abstraction with [pp/absname] works great, but pd searches for the helpfile in: abs/pp/pp/absname-help. Even if i explicitly set the helppath to abs/pp, the same search (abs/pp/pp) is done and the helpfile isn't found of course. This is pd version 0.40-2. Is this normal? Am i missing something? regards, Peter

GEM: pix_movie loss of quality with new version (old version was OK but crashed)
by Matteo Sisti Sette 15 Jun '07

15 Jun '07

Hi, I already posted this to the gem-dev list, but maybe some user here knows a solution or workaround... I found the same question in the archives, dating back to a few years ago, which remained unanswered. I'm using GEM with PD Vanilla 0.40.1 on Windows XP. Up to a few days ago I was using gem-0.90.1-W32-i686-bin, believing it was the latest version. With that version, pix_movie sometimes crashes when opening an avi file, if it had previously opened another one (or the same one). It also crashes sometimes when closing/opening a patch, creating/destroying the gemwin, or closing PD. Very unstable. Now I have installed gem-CVS20060412-NT-i686-bin It is stable, but the video is rendered at a lower quality. I'm testing the same patch with the same videos on the same machine. It is NOT displaying only solid colors. Colors are fine. It rather looks like as if the movie was encoded with more compression or with a worse encoder than it indeed is. Or maybe as if it had a lower resolution. It used to look just fine with the older version of GEM. The movie is being mapped on a rectangle which fits the windows with the same size as the movie, i.e. one pixel of the movie to one pixel of the screen: there should be no interpolation involved. Also, the movie are not interlaced. However, the really relevant thing is that the older GEM version rendered the video just fine, at its full quality, while the new version is degrading quality. Any idea why? By the way, I tried version gem-CVS20060914-W32-i686-bin but that doesn't work at all: it renders a white rectangle, and outputs the message "GL: invalid enumeration" at every frame. Is there any version available that renders at full quality AND doesn't crash? I really need to reload video files at times. I have to use a huge lot of video along the performance, but the performance is split into parts, each using 15-20 videos (no more than 3 simultaneously, but randomly switching among all the 15-20 ones at any moment). My only workaround in order to avoid loading new videos in the same pix_movie object, was to have a huge lot of pix_movie objects with their file opened since the beginning, and just activate them when needed. It doesn't work because the memory start trashing when the 40-50-th movie is accessed, and eventually it even crashes PD! The new version solves all this as it allows me to safely reload movies, but the loss of quality is just unacceptable for the performance. I'm not decorating amazing 3D shapes with coloured videos. I'm just reproducing high quality video at its full size. Any help would be really appreciated.

Pduino-0.3: short report
by Roman Haefeli 14 Jun '07

14 Jun '07

hello hcs finally i found time to play around with arduino and pd again. therefore i tried v0.3 of the pduino software. technically, i don't have any issues at all. it just works _very_ smooth. even with analogue inputs enabled. also the pwm-outputs seem to work well. thanks a lot for your work! some little issues i came across: - sometimes abstractions from mapping-library are invoked with a prepended mapping/ (for example: [mapping/resample] in [pd ANALOG-INPUT] in arduino-help.pd) and sometimes not ([bytemask] in the [arduino] abs). for consistency's sake, it would make sense to always use namespaces, wouldn't it? - the numbers in [pd DIGITAL-OUTPUT] in arduino-help.pd are messed up. - [pd INSTALL-NOTES] in arduino-help.pd needs an update: * [speedlim] isn't used anymore. * [bytemask], [debytemask] and [tolist], or the [mapping] library should be mentioned. cheers roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de

Re: [PD] (netpd)U(Pd-extended)

(assuming that this message didn't arrive to the list, sorry if you've received this mail twice, I've also corrected the end of the message) Hi eni, Le samedi 09 juin 2007 à 11:26 +0200, Enrique Erne a écrit : > hi patko > if you miss an abstraction there is something wrong with your setup. No, I seriously think that if I miss an abstraction, there is something wrong with the documentation, or comments, and I am not talking about net-pd. I'd rather rebuild my own set of abstractions than looking for the missing patch if I have to surf internet, ask questions to pd-list for getting answers. An undocumented patch is almost always a waste of time for every pd users. I can tell this for myself too. > i think i can say _every_ netpd-patch that uses abstractions has > a subpatch [pd abslist] with a list of msgs containing all used > abstractions. > > when one netloads a patch, _creator.pd will read the abslist and tells > all > the users that it is going to upload a patch with the specific > abstractions > and version number. Yes, that's a very cool functionning, it could save everyone a lot of time, and it would be even better if _creator.pd was able to update itself, and why not letting it update absolutely all the files (even the ones in the bin directory)? It would certainly require a 'pd repositories'. > i was thinking about removing my name from the patches and make it more > welcome for changes (see kyle's movie about os)... so far we were > cautious in changing others patches. > usually we change the name ultrahardcoresynth-eni.pd and do changes and > suggest it > to the original author... but many authors are not active.. hmm that's > an other topic. Instead of uploading abstraction from a net-pd user's computer, it might be better if the abstraction were uploaded from a net-pd repository. Any one that would like to add abstractions to net-pd would have to submit them to an active authority of the net-pd project, then it would avoid a lot of mistakes, and the autor would still be referenced but rather in a net-pd database than into the patch, were more usefull information could be displayed. > what information would you like to see in the patches ? I simply would like to be able to understand without having to browse all patches and subpatches hundreds of times for having a clue about how the objects are functionning. For example if I want to put an FX-insert into an net-pd instrument I've made, I take a look at how it has been implemented in other intruments and in the mixer, and I give up after two hours because it's a real mess, there is absolutely no explanations anywhere. Just seeing 'information' would be a good start, ;). > - dependencies... Well I hope you've seen that we are talking about two different things through this discussion, net-pd and pd-extended, and net-pd allready resolve this 'dependence' problem with [pd abslist]. Maybe [import] in pd-extended would fix missing externals, with at least giving the name of the missing ones. > what do you mean with "original abstractions" ? Let's say: "an abstraction that isn't into the pd documentation"

nqlbyl
by Jamie Bullock 14 Jun '07

14 Jun '07

Hi, Please find attached a little abstraction that some may find vaguely useful. It is a piece of logic that filters out jumps in the input stream - a bit like CNMAT's Max external [lbyl] but 'not quite' (hence the name). Suggestions for improvements welcome. BTW: I started by trying to a full [lbyl] as an abstraction and gave up, but I'm sure it would be possible if I had a clearer head... Jamie

Re: [PD] {netpd}U{Pd-extended}
by Kyle Klipowicz 14 Jun '07

Hi Eni~ I also am curious about Roman's opinion, but I'm glad that you're on board! Installation was surprisingly simple. I just copied the netpd directory to my normal ~/Pd dir, and edited my .pdrc file for -path and -helppath stuff. After that, it was a snap to grap the stuff from you (luckily you checked the netpd chat before work that morning). I'm completely blown away by the efficiency of the system at handling all this stuff, especially since it's all written with Pd! I showed my friend a bit of it tonight, and he was equally excited and impressed by the sort of anarchic democracy that exists in the netpd performance world. As a side question, has anyone ever tried to write all the netpd events to a [textfile]-based sequencer so that they can easily record and replay good moments of jam sessions? It seems like it would be fairly trivial to do this, since all that info is being routed through the server anyway. This could be the making of a total automation engine for Pd! Anyway, I guess we're all waiting for Roman to be done enjoying his vacation and get back to the screenland to give his thoughts on all of this. I'm totally digging the energy flying around this idea. ~Kyle On 6/13/07, Enrique Erne <pd(a)mild.ch> wrote: > i'm glad you like it. was it hard to install? > > if i'd maintain it into cvs first thing i would do is add plain/basic > netpd. > then i would add some patches to the 2 directories netpd/patches and > netpd/abs. > > btw. if you disconnect the chat from the netpd server everything works > locally. > it opens a bridge from [s netpd-broadcast] to [r netpd-receive] > > i want to know romans opnion about (netpd)U(Pd-extended) > > On Jun 12, 2007, at 6:38 PM, Kyle Klipowicz wrote: > > > After playing around a little bit with netpd over the past few days, I > > think that it would be possible to write a dummy _controller.pd that > > would allow a user to have the netpd experience without an internet > > connection.

GEM FTGL Sadness
by timon 14 Jun '07

14 Jun '07

To whom it may concern, Some time ago I was explained the issues of why FTGL libs was not included GEM for the extended OSX release of PD. The answer did not make me any wiser. The conclusion was "Compile it yourself". Its a shame that such a great tool (as GEM could be) is falling into the shade by elitist attitude. Bugger, time to switch. T.

OSC stuck
by James Hearon 14 Jun '07

14 Jun '07

OSC in Pd ext.version 0.39.2, Fedora Core 6, planetCCRMA error: /usr/lib/pd/extra/oscx/sendOSC.pd_linux: /usr/lib/pd/extra/oscx/sendOSC.pd_linux: cannot restore segment prot after reloc: Permission denied sendOSC ... couldn't create OSC ... couldn't create tried $Pd -lib oscx, also $sudo Pd -lib oscx also tried import oscx as an object also tried setting startup flags nothing seems to fire off the sendOSC obj, but other libs seem working fine, ex. iemlib Also somehow managed to get the File/Startup menu stuck. The window for setting flags won't open now, an d terminal says: open: No such file or directory No such file or directory invalid command name "OSC" I'd appreciate any helpful hints on getting OSC to work. thanks. _________________________________________________________________ Get a preview of Live Earth, the hottest event this summer - only on MSN http://liveearth.msn.com?source=msntaglineliveearthhm

basic composition tutorial
by Andy Farnell 14 Jun '07

14 Jun '07

Hi, Any feedback on a new document would be nice. I've tried to provide an absolutely minimal elementary intro to making music with Pd. This is the first doc, which I did as a guide for a workshop in Bristol next month. http://www.obiwannabe.co.uk/html/music/musictuts/compose1/composition1/comp… I'm using the new tool scripts for working in TeX, so thanks once again to all who helped me make those work. Cheers, Andy -- Use the source
