Reading a specific image from [pix_buffer] and saving it using [pix_write]
by Antonio Roberts 16 Jul '12

16 Jul '12

I've been attempting to build on the stop-motion animation patch that guido built some time ago (attached). I want to output each new frame to an image but there's one problem: [pix_write] reads what is currently in the frame buffer, which could be one of the old pictures. Is there any way to make it read from a specific point in the frame buffer?

variable receive objects?
by Jörn Nettingsmeier 24 Jun '12

24 Jun '12

hi *! i'm playing around with a theatre cue player written around readanysf, which i will post on the web as soon as i'm sure it's not going to be too embarrassing - need to pick up some more pd idioms first... so far, i've been able to create a nice gui using graph-on-parent, and all gui events are messages sent to receive objects, internally. for instance, hitting the "play" bang button will send the bang to cfPlayer$0SetPlay. the idea is that everybody can grab this event, not just the readanysf~ object. now i've painted myself into a corner: i want to create a midi controller abstraction which is separate from the player and gui. to that end, i have added an outlet to my player that contains the player's unique id $0. this outlet is connected to the controller object, which can now happily send messages back to the player, using message boxes: |inlet| <-- gets the parent player's $0 ID |set $1( | ( |; cfPlayer$1SetPlay bang( that gives me nice separation. the problem is that i want the controller object to be able to _listen_ to player events as well as generate them, so that the midi controller always reflects the current state, even if it was initiated elsewhere, such as via the gui or by loading a playlist item. is there a way to generate a variable receive object similar to a send via message box, whose source is defined at load time? something like this: |inlet| <-- gets the parent player's $0 ID |set $1( | ( |receive cfPlayer$1GetPlay( which, of course, doesn't work. or maybe i'm totally up the wrong alley, and someone can suggest a more idiomatic way to deal with this issue? what i want is this: player doesn't know or care who's controlling it. controller can (and does) have knowledge of the player event model. this way, i can easily add OSC or playlist controllers later, keeping the main player nice and simple. best, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net

MIDI input problems in PD
by Villa Anna 24 Jun '12

24 Jun '12

Dear list, I have problems with Midi input in PD. I use Windows 7 and make use of a Motu 828MKII soundcard. I receive MIDI via a polytouchin object (make use of FSRs and a coridium armmite to translate pressure on the FSRs to Midi messages). All goes fine in the beginning, but sometimes after a while (f.e. 2 hours) my Midi input starts to be random (FSRs trigger that are not supposed to be triggering). If I restart PD everything is back to normal. Any idea what the cause of this problem might be? It's an installation project so it is difficult to restart everything from time to time. Thanks in advance for your help! Laura

GEM + Boids
by Oussama Mubarak 19 Jun '12

19 Jun '12

Hi, I'm new to PD and trying to use boids (http://puredata.info/community/projects/software/boids) with GEM (http://puredata.info/community/projects/software/gem). The example "boids2d-help.pd" (attached) that comes with boids is almost what I need, but it renders each boids result in a separate pd subpatch; in "pd gem_example" a route object is used to route each result of boids to a separate subpatch "pd boid" which takes care of the gem rendering. Is there a way to send the results of boids to one subpatch that would take care of all the rendering no matter how many boids results there are ? This would allow me to fluctuate the number of boids without having to create and attach new subpatches. Any help is highly appreciated. Best, -- Oussama Mubarak http://semiaddict.com

why havent i seen more usage of tables as patch storage? save contents automatically loads last saved value, easy to load file into. perfect patch memory or any kind of memory for that matter.

gemwin frame rate limit?
by William Brent 31 May '12

31 May '12

Hi list, I'm trying to get the fastest possible frame rate from GEM, and seem to be hitting a limit of 60fps. Is this a known limit? I searched the documentation and pd-list archives, but maybe I'm missing something. The final application I'm working on is video tracking, but here's a test patch with nothing more than a gemwin and a counter incremented by the gemhead. With a frame rate of 90 for the gemwin, it takes exactly 3 seconds to get the counter up to 180, when it should only take 2 seconds. At a frame rate of 60, it takes the expected 2 seconds to get the counter to 120. I'm running this with Pd-0.43-2 and GEM 0.93.3 on Ubuntu 12.04 using the -noaudio flag. I get the same results on Mac OS 10.6.8. -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com
