Thread support
by Jorge Cardoso 26 Nov '03

26 Nov '03

Hi, I'm a newbie to this PD thing so excuse me if I'm asking a dumb question: Does PD have any kind of thread support? I'm thinking of using it as a server that accepts requests over the network, does some processing stuff and sends the result back to the client. Now I want to be able to do this for many concurrent requests... I guess that something like this would be hard to do without threads. Any comments? Thanks, jc Jorge C.S.

pdp & libquicktime-0.9.2
by Tom Schouten 25 Nov '03

25 Nov '03

hi all, for anyone having problems with libquicktime and pdp i've made a (temporary) patch to libquicktime 0.9.2 that removes the thread support in the mjpa/jpeg codec. the decoder/encoder thread seems to go into a loop when pd is running with rt scheduling. (the lqtplay utility included with libquicktime has the same problem). http://zwizwa.fartit.com/pd/pdp/libquicktime-0.9.2-mjpeg-0.1.patch.gz cd libquicktime-0.9.2 zcat libquicktime-0.9.2-mjpeg-0.1.patch.gz | patch -p1 btw, there seems to be avi support in this lqt release. i didn't try yet myself.. tom

symbol object
by B. Bogart 25 Nov '03

25 Nov '03

Hey all, With all this OSC stuff I've started using symbol boxes to type in OSC names. I have found it lacking a few nicities. The ability to click and edit the text without typing the whole thing in again would be very nice. (with cursor keys like in a message box, only in run-mode) Past that a symbol scroolback buffer would be amazing, so one could scrool up and down (via cursor) keys through the different symbols that have been entered. The next step after that could be a dropdown box. I think this is doable using toxy but a pd internal/external would be nice. Thanks! Ben

I also think that segmented patch cords and a way to know what each inlet/outlet stands for should have a higher priority than moving to another gui toolkit. Adding the option to group-assign color to message/object/number boxes should not be too difficult and probably would help readability. ::: sam ::: > Date: Sat, 22 Nov 2003 23:52:36 -0500 > From: Michal Seta <mis(a)creazone.32k.org> > Subject: Re: [PD] about pd's gui > To: pd-list(a)iem.at > > On Sat, 2003-11-22 at 19:46, Jerome Etienne wrote: > >> pd is a graphical language, so a nice gui isn't a luxury. > > Isn't adding 'niceties' to existing, working products a luxury? > >> it provide good readability, which improve the developpement >> time and even more the maintenance time. > > I don't think that 'nice' will accomplish the above.

conditional flow in a patch?
by qweqwe wqwewq 25 Nov '03

25 Nov '03

Geetings. I'm new to this forum and PD. I have to do a work in my University and i'm using PD and 3 MIDI pressure sensors. Based in the output of that sensors, i need to launch 7 different patches in PD. So, i need to have a little abstraction where i analyse the 3 sensors: - sensor 1 will output 0 if its below 30 and 1 if its below 30 and below 127 - sensor 2 will output 0 if its below 50 and 1 if its below 50 and below 127 - sensor 3 will output 0 if its below 70 and 1 if its below 70 and below 127 So, i have 2X3 (8) options and i'll only use 7. For example, if sensor 1 out is 0 and sensor 2 and 3 outs are 1, i will launch patch 3; if sensor 1 out is 1 and the others are 0, it will launch patch 5, and so on, based in the 0's and 1's combination of the 3 sensors. Another problem is this. I want to read the inputs with 1 min interval, so a patch will stay for one minute minimum, after that i'll read the values, and if they are diferent, it'll launch another patch. If they are the same, it'll stay the same patch and will not retrigger the same one. And finally, another problem... I'll give priority above all other sensors to sensor 1. This is: when i read the values, if the reading in the sensor 1 is greater than 70 from the previous reading (say, last reading was 27 and next min i have 120), it will launch a certain patch of the total 7 that i have (patch 7 for example) and in this case the outs of sensor 2 and 3 wont matter. Being a newby i'm finding this a little confusing to do (read i don't know how to do this...). So, any help would be apreciated of what i should look at, or any draft abstraction/patch that someone might have that could help me out...

problem using comport and basic stamp
by Hugo Dini 25 Nov '03

25 Nov '03

Hi! Sorry if the following problem Im having is a bit sketchy, but I need to figure it out before wednesday Im having a little problem interfacing the comport serial object with a basic stamp (seems easy?) I send a variable named mojo (word 16bit) from the basic stamp (com1, 9600 baud, parity none, data bits 8 and no flow control) with the command: SEROUT 16, $4054,[ mojo ] (I also tried: SEROUT 16, 9600,[ mojo ] Open pd.. open testcomport.pd open com1 Then I get lots of unwanted numbers that repeat in a pattern. Only one of these numbers seems to be the variable I want, yet it is now reduced in 8bit (0-255) so I tried changing my variable to 8-bit then I tried changing some serial settings I could try to filter out those numbers, but I hope theres a more elegant way Thanks if you read this far Hugo Hugo hugodini(a)warpmail.net -- http://www.fastmail.fm - A no graphics, no pop-ups email service

Aw: [PD] Frage zu GEM/PD
by huolong＠arcor.de 25 Nov '03

25 Nov '03

hi Michael, ich bin nicht die beste wahl (im diesem mailing-list) um Pd/GEM auf deutsch zu beschreiben, aber hier ist mein 2 cents: Pd ist ein "objekt orientiertes programmier sprache" (meist für multimedia sachen), und in diesen fall ist "objekt" wirklich bildlich gemeint ;). du generierst objekte (kästchen) und verbindest die mit einander durch kleine linien... GEM ist ein "external" (plug-in) für Pd. also ein zusatzmodul für Pd um 3D objekte zu generieren, manipulieren und animieren... viel glück -andre ps. bei weiterem fragen kannst du mich auch direkt mailen, ich helfe gerne ! ----- Original Nachricht ---- Von: Michael Gschiel <gschiel(a)kfs.oeaw.ac.at> An: PD-list(a)iem.at Datum: 25.11.2003 10:01 Betreff: [PD] Frage zu GEM/PD > Hat jemand eine Kurbeschreibung entweder zu GEM oder zu PD oder beide, die > auf Deutsch ist? > > Vielen Dank im voraus! > > Mit freundlichen Grüßen > > Michael >
