data structures: sugestions for future implmentation
by João Pais 14 Sep '09

14 Sep '09

Hi all and specially Mr. Puckette, I've been working more with data structures in a new patch. Although some nice things are possible, there are still some details that might give much more power to their possibilities. Most of these sugestions become only evident when one works with more than one template (struct) in the same patch. To know my context, I'm working now with a template with 5 arrays inside. Probably other templates might come with more or less arrays - or maybe in the end only one (super-)template, with as many activated arrays as necessary. My sugestions are: - be possible to set the parameters dynamically with a "set ..." message, like in many other objects. Because all objects get hard-coded with the first structure given, it's necessary to create many copies of the same code if you want to run the same operation through different templates (or even different arrays on the same template). E.g. if you use [tabread], you can use only the same object to read different tables. But if you use [get], [set], [element], ... you need as many objects as structs. And if something changes in the structure of your template, you need to make X changes to the patch. - automatic pointer output from the struct by clicking in the structure also not in edit mode. This allows a much easier compositional work on the fly. - a "select 0/1" command given to a pointer, that would behave like a mouse selection in edit mode. or "highlight", to show in which atom the pointer is. - a "displace x y" command. of course this can be already coded, but if it would be inside the struct object would be much faster - a "previous" command for a pointer, or even "previous x" and "next x". being at that, maybe even a "first" and "last" as well. - to choose faster between different "notes" (data structure atoms) on my "score", I'm assiging an id parameter to the struct, and these get reassigned each time the score is sorted. since each pointer already has its own identity, would it be possible to make this number/symbol transparent? then it would not be necessary to make more code to do the same function. an extra would be a flag to display/hide this number/symbol. actually I don't really know what's inside a "(gpointer)" - it looks like if instead of having number boxes, one would only get (float) when trying to see the result of an operation. - general [get] that doesn't depend on a struct, solely on common parameters. This can be used, for example, to make a list of all x and y (and w) elements of different templates/arrays - without making a copy for each template. - does the scale function work only for the display of data (with draw-objects)? If yes, I guess it would be advantageous to have this control already at the data level. And if not, how is it possible to use this feature to limit the values of a struct? (and not only of its representation) Can it be that there's a memory bug somewhere? Besides some crashes when templates get changed, also once was noticeable by looking at the properties window that structures kept parameters already deleted. (have no concrete example now to show) Best, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 Studio +49 30 69509190 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

I did found something similar in the libs, so I make this abstraction to scale a signal in a given range, something like 'scale' or 'range' for signal. it may be useful for others. loic signal-range~: ------------------ #N canvas 0 22 450 300 10; #X obj 41 276 outlet~; #X obj 41 248 +~ 0; #X obj 41 215 *~ 0; #X obj 41 193 /~ 0; #X obj 234 116 t b f; #X obj 234 144 - 0; #X obj 129 118 t b f; #X obj 129 146 - 0; #X obj 41 135 -~ 0; #X obj 41 21 inlet~; #X obj 371 22 loadbang; #X obj 129 21 inlet; #X obj 186 21 inlet; #X obj 243 21 inlet; #X obj 300 21 inlet; #X obj 129 77 f -1; #X obj 186 77 f 1; #X obj 243 77 f -1; #X obj 300 77 f 1; #X connect 1 0 0 0; #X connect 2 0 1 0; #X connect 3 0 2 0; #X connect 4 0 5 0; #X connect 4 1 5 1; #X connect 5 0 2 1; #X connect 6 0 7 0; #X connect 6 1 7 1; #X connect 7 0 3 1; #X connect 8 0 3 0; #X connect 9 0 8 0; #X connect 10 0 15 0; #X connect 10 0 16 0; #X connect 10 0 17 0; #X connect 10 0 18 0; #X connect 11 0 15 0; #X connect 12 0 16 0; #X connect 13 0 17 0; #X connect 14 0 18 0; #X connect 15 0 8 1; #X connect 15 0 6 0; #X connect 16 0 7 0; #X connect 17 0 1 1; #X connect 17 0 4 0; #X connect 18 0 5 0; signal-range~-help: ------------------------------ #N canvas 410 414 480 370 10; #X floatatom 188 265 5 0 0 0 - - -; #X floatatom 219 96 5 0 0 0 - - -; #X floatatom 259 96 5 0 0 0 - - -; #X floatatom 298 96 5 0 0 0 - - -; #X floatatom 336 97 5 0 0 0 - - -; #X msg 407 110 bang; #X obj 187 236 snapshot~; #X obj 406 88 metro 20; #X obj 406 65 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 1 1; #X msg 298 73 100; #X msg 336 73 1000; #X obj 109 218 osc~ 100; #X obj 109 248 dac~; #X obj 109 95 osc~ 0.25; #X obj 314 40 loadbang; #X obj 117 171 signal-range~; #X connect 1 0 15 1; #X connect 2 0 15 2; #X connect 3 0 15 3; #X connect 4 0 15 4; #X connect 5 0 6 0; #X connect 6 0 0 0; #X connect 7 0 6 0; #X connect 8 0 7 0; #X connect 9 0 3 0; #X connect 10 0 4 0; #X connect 11 0 12 0; #X connect 11 0 12 1; #X connect 13 0 15 0; #X connect 14 0 9 0; #X connect 14 0 10 0; #X connect 14 0 8 0; #X connect 15 0 11 0; #X connect 15 0 6 0;

selector~ equivalent for pd ?
by Loic Kessous 14 Sep '09

14 Sep '09

Hi, I didn't found an equivalent to max external "selector~" , I made this ugly abstraction for 3 inputs but I wonder if there is something more standard and that can accept argument to set the number of inputs. is there one? I used 'mixer~' which is ggee to do it, so there maybe some way to do this with some scripting... or just by making a new external by code... let me know, so I may think about making one if necessary. loic selector~ for 3 signal inputs: -------------------------------------------- #N canvas 272 176 717 638 10; #X obj 272 391 osc~ 220; #X obj 272 411 *~ 0.1; #X obj 326 411 *~ 0.1; #X floatatom 326 368 0 0 0 0 - - -; #X floatatom 272 368 0 0 0 0 - - -; #X msg 214 338 1 \$1; #X floatatom 122 266 0 0 0 0 - - -; #X floatatom 79 266 0 0 0 0 - - -; #X msg 170 337 0 \$1; #X obj 326 391 osc~ 330; #X obj 257 529 dac~; #X obj 147 235 expr (1 -$i1); #X obj 390 412 *~ 0.1; #X floatatom 390 369 0 0 0 0 - - -; #X floatatom 164 264 0 0 0 0 - - -; #X msg 256 336 2 \$1; #X obj 262 471 mixer~ 3; #X obj 390 392 osc~ 550; #X obj 109 174 route 0 1 2 3; #X msg 110 139 0; #X msg 140 145 1; #X msg 180 140 2; #X msg 207 144 3; #X floatatom 312 266 0 0 0 0 - - -; #X floatatom 269 266 0 0 0 0 - - -; #X obj 296 232 expr (1 -$i1); #X floatatom 354 264 0 0 0 0 - - -; #X msg 152 204 1; #X msg 297 203 1; #X floatatom 463 267 0 0 0 0 - - -; #X floatatom 420 267 0 0 0 0 - - -; #X obj 447 233 expr (1 -$i1); #X floatatom 505 265 0 0 0 0 - - -; #X msg 448 204 1; #X msg 58 225 0; #X obj 140 120 loadbang; #X obj 58 134 inlet; #X obj 315 529 outlet~; #X connect 0 0 1 0; #X connect 1 0 16 0; #X connect 2 0 16 1; #X connect 3 0 9 0; #X connect 4 0 0 0; #X connect 5 0 16 0; #X connect 6 0 5 0; #X connect 7 0 8 0; #X connect 8 0 16 0; #X connect 9 0 2 0; #X connect 11 0 6 0; #X connect 11 0 14 0; #X connect 12 0 16 2; #X connect 13 0 17 0; #X connect 14 0 15 0; #X connect 15 0 16 0; #X connect 16 0 10 0; #X connect 16 0 10 1; #X connect 17 0 12 0; #X connect 18 0 34 0; #X connect 18 1 27 0; #X connect 18 2 28 0; #X connect 18 3 33 0; #X connect 19 0 18 0; #X connect 20 0 18 0; #X connect 21 0 18 0; #X connect 22 0 18 0; #X connect 23 0 5 0; #X connect 24 0 8 0; #X connect 25 0 26 0; #X connect 25 0 24 0; #X connect 26 0 15 0; #X connect 27 0 11 0; #X connect 27 0 7 0; #X connect 28 0 25 0; #X connect 28 0 23 0; #X connect 29 0 5 0; #X connect 30 0 8 0; #X connect 31 0 30 0; #X connect 31 0 29 0; #X connect 32 0 15 0; #X connect 33 0 31 0; #X connect 33 0 32 0; #X connect 34 0 8 0; #X connect 34 0 5 0; #X connect 34 0 15 0; #X connect 35 0 20 0;

Re: [PD] iPhone control
by Koray Tahiroglu 14 Sep '09

hi, I used mrmr earlier (http://poly.share.dj/projects/#mrmr http://poly.share.dj/wiki/index.php/Mrmr they are both down at the moment I don't know why) and did some test runs for the system that I have been developing. It is an open source project that gives you touch screen and accelerometer control data through OSC. It allows you to design your control interface on iPod Touch or iPhone and only allows one way OSC data transfer. You can also receive touch screen and accelerometer control data with a very simple rjdj scene through netsend/receive objects, but there are some problems with touch screen control data, sometimes it is not as accurate as mrmr or others. rjdj doesn't work with 1st generation iPod Touch. I would suggest to check mrmr, later on you will end up developing a custom application based on your project/application needs, thats what I am working on whenever I have time for that :) Koray ------------------------------------- M.Koray Tahiroglu Acoustics Lab / TKK http://mlab.taik.fi/~korayt/ http://www.acoustics.hut.fi/~ktahirog/ tel: +358 45 233 6272 On Sep 12, 2009, at 9:21 PM, pd-list-request(a)iem.at wrote: > Message: 3 > Date: Sat, 12 Sep 2009 09:55:14 -0400 > From: The Space Between the Words <info(a)thespacebetweenthewords.org> > Subject: Re: [PD] iPhone control > To: fred-ordi <ordi(a)fredvoisin.com> > Cc: "pd-list(a)iem.at" <pd-list(a)iem.at> > Message-ID: > <F8120B32-D4AD-433C-BCCD-D29F94B9CD19(a)thespacebetweenthewords.org> > Content-Type: text/plain; charset=us-ascii; format=flowed; delsp=yes > > My initial motivation was the ability to have a touch screen > controller, with pd running on my MacBook. > > Regards, > Jerome > > On Sep 12, 2009, at 9:08 AM, fred-ordi <ordi(a)fredvoisin.com> wrote: > >> I'd like to try, but rjdj doesn't want to install thru itunes (mac) >> on my (old jailbroken) ipodtouch...

Each additional dlopen() takes one filehandle and each filehandle probably takes a lot more RAM than the machine code of the average zexy class. Given dlopen() uses mmap() which loads the *.pd_linux file content on-demand (in 4k blocks), one big *.pd_linux file is more memory-efficient than one-class-per-file, even when using a low number of different classes. On top of that, if your external takes 1k, it's padded to 4k, and if it takes 4.001k, it's padded to 8k, etc. however, if you loaded all of pd-extended as big libs, it would have a greater virtual-memory-size than one-class-per-file, but that doesn't have any advantage in practice. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

GEM help patches not found on Windows XP
by r＠raakvlak.net 13 Sep '09

13 Sep '09

Hi, I'm trying to get Pd to find the GEM help patches for its objects, but am having no luck so far. Default installation of pd-extended (version 0.40.3) keeps giving me 'sorry, couldn't find help patch for ...' messages I've added the path C/Program Files/pd/extra/Gem to paths. Still no love. I have noticed that the folder with GEM helpfiles appear to be in two locations; /extra and /doc/5.reference - is this normal? All other helpfiles seem to work without a problem, just can't get Gem to behave :S BTW, I've seen this identical problem on every windows installation I know (over half a dozen), including 1 under a virtual machine on Mac OS X. The Mac-native version of pd-extended does not have this problem. The problem is compounded by Pd starting a new instance when you double-click a patch under Windows. If it would open in the same intance, I'd just have a window with help patches open... Any help in solving this would be greatly appreciated. Thanks

pd as vst plugin under linux
by Atte Andre Jensen 13 Sep '09

13 Sep '09

Hi Prompted by a recent thread on linux-audio-user I'm looking into getting pd running as a native linux vst plugin. I found these: http://www-crca.ucsd.edu/~jsarlo/pdvst/ http://www.halftheory.com/hetleveiker/pdvst.html They seem to be windows-only solutions, though. Is is possible to run pd as a vst plugin under linux? If not, are there any work being done in this direction? -- Atte http://atte.dk http://modlys.dk http://virb.com/atte
