Glitches on Mac with Gem
by Daniel Almeida 15 Nov '08

15 Nov '08

I've made a patch to Vj, with a wav file being played, two image layers and a few pix effects life 3 motion blurs, 1 operation (this can be changed, add, subtraction or multiplication. only one operation work at a given time), pix_colorize, pix_posterize and pix_contrast. the effects can be turned on/off. Ocasionally there are some glitches in the sound. I'm using a Tascam US-122L or the computer sound card. I've tried to change sound delay with no effect. each time there is a glitch, there's a peak in the disk activity. Also, I'm doing some calculations to automaticaly get the frame interval to sync each loop to the beat. this beat is constant. any idea? how can I optimize my patch? Thanks for any help Daniel Almeida

Re: [PD] cant load libraries
by Conor Higgins 15 Nov '08

sorry to keep going on about this but the problem seems to be something to do with Leopard on OSX....has anybody had a similar problem with Leopard not running the correct libraries?... I have spoken to a few people who have Leopard and none of them load the libraries on start up...

scratching my head about zexy
by Roman Haefeli 14 Nov '08

14 Nov '08

hi all, hi IOhannes after having installed pd 0.42.0test5, i assumed to have discovered a behaviour change of [unpack] and [pack], until i noticed: a) zexy comes with its own version of [pack] and [unpack]. why are they called the same? i really don't get that. b) in pd 0.42.0test5 they seem to override the built-in classes. is this a bug? if yes, pd's or zexy's? c) the zexy versions can explicitly be called by using the 'zexy/' prefix. how is that possible, although zexy was compiled as multi class library? is that _the_ solution to have multiclass libs and separate namespaces at the same time? it's definitely not backwards compatibility safe to replace all built-in [pack]/[unpack] by the zexy versions, since the zexy versions reads the 'f' and 's' literally and thus some patches produce lots of errors (due to inlets receiving 'f' instead of '0', for instance). roman ___________________________________________________________ Der frühe Vogel fängt den Wurm.

Re: [PD] first release of libsms + pd externals
by Rich E 14 Nov '08

14 Nov '08

Updated the packages with minor scons fixes. I also added a picture of the main help file, which will tell you a little about what the set of pd externals do: http://mtg.upf.edu/static/libsms/sms-help.jpg I saw that my scons installer is not yet working too well in os x.. I think it is because it cannot find the directories where headers/libraries are installed. So I added the basic ones that I could think of (and what worked on my friend's macbook). Also, there is a "verbose" command that can be given to scons that will print out what directories it is about to look for the libraries.

I think it will compile in the static libary too, if it is found. What is the error you are getting? My guess is scons is not finding libsndfile at all. > i have no idea how other packages handle that.. or you have a look ad the > build scripts in the pd-extended installer... The problem is that it is hard to find examples of scons being used to build pd externals. And I personally do not like make :) > well....its quite early for an OS X Version i guess Hopefully within a few weeks of testing the install problems will be smoothed out. I have it working on my G4 in the office, but I mainly compile things just like I would in linux. I know this is different from most Mac users, which is a large population of the Pd community.

Re: [PD] dynamically set "graph on parent" option?
by Matt Barber 14 Nov '08

14 Nov '08

By the way, it seems that one argument in a "donecanvasdialog" message corresponds to both the "graph on parent" and "hide object name" toggles in the gui dialog -- 0 for both toggles off, 1 for just GOP on -- any other integer for both toggles on.

In this case, it was 30fps and 48000Hz, so it is an even multiple. I guess it seems odd to me to be using ~ objects for the frame clock, but I suppose it could be not so weird.

fftease one more time
by Lao Yu 14 Nov '08

14 Nov '08

Hi, the lib refuses to load under OS X.4 and OS X.5 on a mactel machine. It is for sure the i38 version. I get the error message "mach-o, but wrong architecture" of which I don't have a clue how I can improve the situation. I do not believe that it is me, the lib at the same location runs well on my ancient and very slo G4 book. Remains something that I haven't seen yet. Does anybody use the lib under OS X on an intelmac? Alternatively, how does it run under Linux? I might just install Linux on my mactel book... Best Jurgen

line~ for syncing to video
by Hans-Christoph Steiner 14 Nov '08

14 Nov '08

I am trying to make a version of [line~] that gives me a line based on the frame numbers I give it. Basically, I give it a frame counter in the first inlet, then start frame and stop frame as arguments. The hard part is that I want it to behave like [line] in that the last value stays in effect until something else overrides it. How do I do that with DSP data? If I use [switch~], then the [outlet~] will just retain its last value. .hc ------------------------------------------------------------------------ ---- 'You people have such restrictive dress for women,’ she said, hobbling away in three inch heels and panty hose to finish out another pink-collar temp pool day. - “Hijab Scene #2", by Mohja Kahf

first release of libsms + pd externals
by Rich E 13 Nov '08

13 Nov '08

Hi all, As some may know, I have been working on updating the SMS code Xavier Serra wrote during his PhD to work in modern-day, real-time systems. It is working quite nice now and decently documented, so here is the first announcement of libsms, a C library for Spectral Modeling Synthesis things. This library is meant to be a clean and efficient implementation of analysis, synthesis, and manipulations in the spectral domain based on the many publications and hours of the people that came before me. I began working on this project because I wanted to use SMS techniques in Pure Data, so I have been building a Pd library of externals alongside libsms. These still need a little more work to get rid of a few known bugs, but the synthesis is clean and fun. It by far surpasses the attempts I previously made with just Pd objects and an external oscillator bank (this was Trax.pd). So go here, download it and tell me what you think! http://mtg.upf.edu/static/libsms/ Of course, this works really nice on my ubuntu machine, and I've been working out the compiling issues in OS X. But who knows, the project is still young. So if things don't work, or if there are any other issues that come to mind, please let me know. cheers, Rich
