batch processing and event execution
by Federico Camara Halac 29 Jan '19

29 Jan '19

Hello, I have three part question regarding -batch processing and (non-DSP) event execution. Say I have a [t b b b] with time-consuming events such as [text], [array], [soundfiler] reading, array normalizing, analyzing, etc. Since each stage of the [trigger] depends on the last, is it a fact that every stage would be executed until completion? I have been using Pd for a while now, and I know this should be true (I have no evidence against it), so I guess what I am asking is How can I really be sure that it is indeed a fact? Is there another flag I can use? This question extends to those objects that write to disk using [write( messages like [text], [array], or even [writesf~]... and also when saving stuff with Gem's [pix_write], [pix_buffer]... When you send a write message of this sort, am I correct in assuming that Pd will stop doing anything else but writing-to-disk until the writing-to-disk is done, and then resume its next task once the file is completely written? Finally, when doing batch processing, does Pd create a "list" of all the events that will take place before doing them? Is there anything of that sort? Thanks! Fede

Purr Data 2.8.0 released
by Jonathan Wilkes 28 Jan '19

28 Jan '19

Hi list, Purr Data 2.8.0 has been released and is now available: https://github.com/jonwwilkes/purr-data/releases/tag/2.8.0 Changes: * Constrained dragging. Version 2.8.0 adds the ability to drag iemguis, subpatches, graphs, grid, and Scope~, with a constraint either vertically or horizontally. There are new cursors that show up when the user moves the pointer along the bottom right-hand corners of these objects. Clicking when the "east-west" cursor is displayed will resize the widget in the horizontal direction. Clicking when the "north-south" cursor is displayed will resize in the vertical direction. Iemgui labels and the [cnv] object also allow constrained dragging. Just move the pointer in the corners of the little "drag rectangle" that appears when the relevant iemgui is selected. (The [cnv] object and the red gop rectangle have two such "drag rectangles.") * Fixed bug with scalar events. In some cases opening a subpatch could unbind the event for the scalar. * Improved help patch for [line] object. The new help file does a better job explaining the function of the 3rd inlet and specifies what happens when the grain size doesn't divide evenly into the total ramp duration. * Added a "footgun" GUI preset. A user stated that Max/MSP lets the user selectively hide cords. Well, in Purr Data we let the user hide _all_ cords and xlets with the "footgun" preset. The name is self-documenting but may come in handy for patches with so much spaghetti that the text in the object boxes is unreadable. Please report all bugs on the issue tracker: https://git.purrdata.net/jwilkes/purr-data/issues Best, Jonathan

rtcmix~
by Eugene Robinson 27 Jan '19

27 Jan '19

Hi I’m having a problem embedding the rtcmix~ object in Pd. I’ve tried dropping the folder as a binary, and also compiled from source in the cmd line. Also have tried in both Pd 49.1 and Purr data-crash! i’m using a mac air circa 2014 with the latest OS. using rtcmix~ from j. matthys. I know this has probably come up before, any help is appreciated. thanks- Gene Sent from my iPhone

Installing GEM on mac?
by J. Simon van der Walt 27 Jan '19

27 Jan '19

I've been away from Pd for quite a while, and I see that pd-extended is no longer a thing? I want to use GEM, so: I have Pd-0.49-1 installed and working. I went to 'Find externals', searched for 'gem' and installed: Gem/0.94~pre1 (deken-archive for macOS Intel/64bit) Uploaded by zmoelnig @ 2018-12-23 18:17:43 This seems to have put some stuff into the Pd app bundle. However, when I try to open an example, most objects don't seem to be found, eg 'gemwin… could not create'. What am I doing wrong? Thanks! -- J.

ugly "already connected" errors
by michael strohmann 26 Jan '19

26 Jan '19

hi! i need to send OSC messages to a number of smartphones via UDP. the phones are used as remote controls for the patch, so i send the status of the patch to the phones every second. since the phones are sometimes out of WLAN reach or switched off, i send a [connect( message to [netsend] every second to keep in touch. and i get loads of “already connected” errors. this might have caused to fill up the ram on the raspi on which pd runs, so i sent stderr to devnull. still, do you think it is better to disconnect every time before connecting, or might this cause some other problems? cheers! mkl

what fdn~ does?
by Alexandre Torres Porres 25 Jan '19

25 Jan '19

Hi, I'd like to figure out what the [creb/fdn~] object does and how I can control it. The documentation is too simple and I don't get what the code does. BTW, code says it's a "a feedback delay network (reverb tail) using a householder reflection feedback matrix (In - 2/n 11T)". Has anyone ever used this object and could help me out? cheers

Using netsend to send url / text to turn a device on and off
by RT 25 Jan '19

25 Jan '19

I'm trying to turn on and off a device using Pd by sending a URL. At the moment to turn the device on I just type in a url in the browser and to turn it off I type in another one url . To turn the device on I send http://192.168.1.123/relay/0/?turn=on To turn the device off I send http://192.168.1.123/relay/0/?turn=off I can connect to the device using *connect* and *netsend* but I couldn't find an example / correct syntax / format on how to send the required url out of Pd. This is what I'm using below #N canvas 162 516 623 513 10; #X msg 535 750 \; pd dsp 1; #X obj 536 724 loadbang; #X obj 248 207 netsend; #X msg 272 110 disconnect; #X floatatom 218 272 0 0 0 0 - - -; #X obj 280 275 print; #X msg 403 171 send /relay/0/?turn=off; #X msg 404 136 send /relay/0/?turn=on; #X msg 184 67 connect 192.168.1.123 80; #X connect 1 0 0 0; #X connect 2 0 4 0; #X connect 2 0 5 0; #X connect 2 1 5 0; #X connect 3 0 2 0; #X connect 6 0 2 0; #X connect 7 0 2 0; #X connect 8 0 2 0;

Re: [PD] Text insert and delete in PdDroid
by Chris McCormick 24 Jan '19

24 Jan '19

Hi Arnault, The [text] element does not work because the version of Pd that ships with PdDroidParty is currently out of date. I'm sort of working on a new build but not sure when I will get that working. Patches welcome! Cheers, Chris.
