I guess what Jamie meant is that during delay-time ramps, the signal in the buffer is being played at a speed!=1 which produces a temporary pitch shift. If what you want is to change the delay time every once in a while, I once implemented it by using 2 delay lines and switching among them: while delay line A is being used, you change the delay time of delay line B and then, once the critical zone is passed away, cross-fade to delay line B and leave delay line A idle.... and then viceversa again and again ..... something like that. I also used feedback. If you need to _continuously_ change the delay time without shifting pitch, I guess you need to apply the same techniques that are used for "non-transposing" time-stretching....

OSX Intel: status of M-Audio / MOTU multichannel in/out, support?
by Collin Oldham 05 Jun '08

05 Jun '08

are you looking for a firewire interface? I have a long sad story about a m-audio firewire 410, which I will otherwise spare you. I'm now using an edirol fa-101, so far happily. Collin

processing images with GEM?
by matteo sisti sette 05 Jun '08

05 Jun '08

Hi, I have to perform some very very simple computer-vision tasks (such as motion detection) on image data captured by a camera, and I was considering/evaluating the possibility of using GEM to do that. It would involve basically computing the difference between two frames, background subtraction, masking an image with another one, computing the avarage value over a rectangular portion of the image, and this kind of things. I'm a bit lost, since I guess there are probably facilities to do such things in GEM, but I don't know where to look for. 1) Are there some pix_ objects to do these kinds of operations in a reasonably efficient way? 2) Is it possible at all to use the openGL wrappers to do such calculations in the GPU rather than CPU? Where may I find examples of that? 3) Are there some objects that already implement the latter approach and offer basic functions at a slightly higher level, such as frame-difference on a texture buffer? If anyone can point me to any documentation/examples/tutorials specific to this kind of things, I'll be very grateful. Or maybe this is not the kind of things GEM is suitable for? Should I forget about it and have a look at other platforms? Thanks, m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

TR909 emulation
by raul diaz 03 Jun '08

03 Jun '08

Hi marius! It only work on windows but could be very easy to port it to mac or linux. Pd patch uses vanilla version with sssad abstractions, mrpeach osc library, and some objects from creb and zexy (ead~, multiplex, demultiplex and lister). So you could use it on mac with pd extended. Processing interface is a windows application (*.exe) but I could export it as a mac application or as web java applet. I attached a rar with mac and linux processing interfaces and pd abstractions. Using pd-extended you only need to open "tr909.pd" and "index.html" on "java applet" folder and it must work. You can look at "application.macosx" folder if you don't want to use graphical interface as web page. I would like to know if you can run it succesfully on mac.

declare who? what?
by Enrique Erne 03 Jun '08

03 Jun '08

hi my original subject was "pd-extended: <~ and matrix" but now i got confused so i renamed it. the newest pd-extended can't create [<~] nor [matrix] on default. [<~] on the 20080523 could create (with an expr~ couldn't create error) now the [<~] can't create anymore. should i file a new bug report for hexloader or is it covered by https://sourceforge.net/tracker/index.php?func=detail&aid=1637460&group_id=… matrix: so far netpd provides a [declare -stdlib iemmatrix] and a [declare -stdpath ../extra/iemmatrix] for pd-extended, but this seems to not work anymore. it is working with pd-ext-20080516 and _not_ working with 20080523. [matrix] creates when i first do a [iemmatrix/matrix] and then load my patches. i also checked the matrix-help bugreport https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1965876&group_… eighthave says: "I added '#X declare -lib iemmatrix' to the help files, so this should work now. Please test tomorrow." i checked it today and the help files is really working. the declare help file says: -lib load a library, relative to the patch maybe i must have missunderstand but the patch in this case would be netpd's _chat.pd wouldn't it? relative to _chat.pd on my system would be something like: ../../../Applications/Pd-extended.app/Contents/Resources/extra or similar. why is -lib iemmatrix working? is the declare-help file wrong? also i am a bit disappointed that one can not write abstractions, that declares what it depends on. but probably that has some technical reason. thanks eni Pd-0.40.3-extended-20080602-macosx105-i386 matrix ... couldn't create load_object: Symbol "0x3c0x7e_setup" not found error: BUG: no pd_objectmaker found <~ ... couldn't create load_object: Symbol "0x3c0x7e_setup" not found error: BUG: no pd_objectmaker found zexy/<~ ... couldn't create

anything (poly~)-similar in pd?
by lukas 02 Jun '08

02 Jun '08

hello everybody, is there a object in pd which is similar to maxmsp's (poly~)? or are there other ways creating a polysynth less workintensive as the one which follows with the newest version of pd? many thanks, lukas lukas(a)zeitgenossen.ch dubcircus.com dfh.ch/radio
