plot target window problem
by gerard van dongen 11 Apr '01

11 Apr '01

Just starting to play with the templates and data structures. How do the plot/draw objects know where to put their output? In a patch I am trying they suddenly appear to plot in their own template window, and not to the data window. Maybe this is because I forgot to make a pd data object first. Is there a way to change this behaviour. regards Gerard

halo list. a little piece done with pd/gem in one real time: www.testphase.at/viz select: sproose rtx q: in the downloaded patch gwin.pd there is an object called 'nop' my pd 'couldn't create'. when i connect 'create,1' directly to 'gemwin' and click the new-message my screen becomes blue with white letters on it. is this correct? pix_video q: should this work in the current release? pd says: pix_video: connected at x:.. but when i start rendering pd crashes. (i am working under w2k) just, joreg. [wannabe]

protecting objects

hi all ! recently i found it quite inconvenient to allow any user to open a sub-patch/abstraction from within a running patch (by simply clicking on it). since the new release introduced the "properties"-option, maybe it would make sense, to add a flag for abstraction which makes them non-openable from within their parent-patch. thus you could open it via file/open (or changing it to "enable open on double click" via the properties.) by the way : would it make sense to create a "pd-play", that lacks of the editing-possibility ? i just think that it might be more secure in several cases (to keep users from incidently damaging patches). mfg.gtr.ztr IOhannes

PD help needed
by Dave Phillips 01 Feb '01

01 Feb '01

Greetings: I've been trying to get PD + GEM working under Linux, but I'm having poor luck at it. I got a great headache trying to compile it (either MP's or GG's version) until I realized that it didn't like my Tcl\Tk 8.0 installation, so I upgraded to 8.3 and PD now compiles without complaint. So then I installed it, according to the instructions in the makefile, to the /usr/local hierarchy. But when I try running it I get this: [dlphilp@localhost src]$ pd -rt successfully opened /dev/dsp write-only successfully reopened /dev/dsp read/write priority 96 scheduling enabled. memory locking enabled. priority 98 scheduling enabled. memory locking enabled. sh: ./bin/pd-watchdog: No such file or directory sh: ./bin/pd-gui: No such file or directory Pd: signal 2 I assumed the install would place everything where needed. My bad. So where does everything need to be in order for PD to find it ? Or what other info do you need to help me debug this situation ? I've successfully compiled Gem 0.84 but since I haven't yet got PD working I don't know if this version will work with PD. If anyone else is using PD + GEM under Linux, please let me know if there are any tips on getting this show working. I'm anxious to see the combination in action... :) Best regards, == Dave Phillips The Book Of Linux Music & Sound at http://www.nostarch.com/lms.htm The Linux Soundapps Site at http://sound.condorow.net Currently listening to: Aphex Twin, "Mold"

Precompile GGEE
by HENRY Damien 31 Jan '01

31 Jan '01

Hi list. Thanks for the tips (using $0 or $1 and the table object) for multiple array. This solve my problem completly. I'm currently using an old version of ggext that don't fit with PD 0.32 Is there a place where I can find compiled (dll for windows) versions of GGEE ? dh

openpanel and soundfiler
by Nakayama Yuta 31 Jan '01

31 Jan '01

Hi, I have trouble in reading soundfiles with openpanel and soundfiler, for example bang -> openpanel -> "read -resize $1 array1" -> soundfiler. While the openpanel appears, PD stops generating its sound. This makes it difficult to change soundfiles during performances. This problem appears even on faster(PIII-900)and much(750M) memory machines. Increasing the "-audiobuf" amount cannot remove this problem. Are there any ways to avoid this interval, except for writing all filenames of soundfiles in Message-box? I'm using PD version0.31 on NT. Thanks, U-ta

[GEM] pix_rtx
by joreg＠gmx.at 30 Jan '01

finally. was able to run the rtx-patch under win98. for about 1 minute before it crashed when i tried to open 'gwin 50 50'. jedenfalls, hut ab iohannes! but. and this is a big but! what i saw was no tx-transformation in its original meaning (see: http://www.tx-transform.com/frame_e.htm -> Technique). as far as i understand this, tx-transform cannot be achieved in realtime since the flipping of space- and time-axis needs two finite values. in a movie the space is limited to its dimensions. but one cannot flip this finite value with the endless time of a live-video. one could only do it in portions consisting of n frames, where n is the width of the video in pixels. you would first have to capture n frames and then, while transforming and outputting the result, capturing the next n frames. the output would then always be delayed n frames. rite? (hope my english says what i mean). what rtx does, seems to me like a delayed horizontal flipping of the video. may be that is what you meant with "...being *completely* different...". anyway. great! pd/w2k at least shows me one picture of the cam now (after some driver-reinstallations), before it dies. u> does your capture card work correctly ? can you capture videoIN with the u> standard hauppauge-applications ? yes. i can capture under w2k. u> win98se + asus v6600deluxe have u tried w2k? pd/gem runs much^3 faster on w2k than on w98 on my hardware. u> what do you exactly mean by "when i leave pd" ? u> actively leaving pd or being left by pd ? u> on my system, pd crashes too when leaving it (pe: via file/quit). i do u> not know the exact error-message, since it doesn't bother me (crashing u> on leaving) yes. i mean that one. just wanted to mention it. only, joreg [wannabe]

writing externals: A_GIMME
by Thomas Grill 29 Jan '01

29 Jan '01

Hi list! sorry, but somehow most of last posting vanished ... i give it a new try ------------------------------- I'm about to dive into the undocumented depths of writing externals for PD... Only one question for the moment: What is an A_GIMME argument for? thanks, Thomas PS. sending a - as i understand it - reserved "dsp" message to a stream object crashes PD.
