Switching Between Multiple Patches for Installation
by Tyler Leavitt 16 Mar '12

16 Mar '12

Hello all, So I have around 8 generative patches/static compositions that I want to present as an installation. Less conceptual, more demonstrative of Pd. So about every 2 minutes I want a fullscreen window of one patch to close and the next patch to open fullscreen so that people can see the inner workings (I plan to do visuals through GEM and a projector). When I say fullscreen I mean fullscreen of the laptop, with the GEM visuals proceeding as usual. I understand how to accomplish the switching of the audio, but to get the patches themselves to take focus I'm afraid I'll need to write a script in Tcl/tkl, which I have no experience in. Does anyone have suggestions, or code from a similar presentation they could share? Thanks, Tyler

nonlocal naming scheme
by Jonathan Wilkes 15 Mar '12

15 Mar '12

Hello, I had another thread where I used my canvas "get" method to hide $0 in s/r pairs in an abstraction and make it possible to more easily specify the scope of a variable using two abstractions named [to] and [from]. Now I'm extending that concept to nonlocal signal objects: s~/r~ and throw~/catch~. After looking through the list I've realized that some of the confusion about these objects occurs because the names are completely arbitrary and don't reflect the one-to-many/many-to-one division between them.* (Side question: are there any many-to-many nonlocal signal externals? If so how does the cpu usage compare to throw~/catch~?) So here are the names for my abstraction wrappers: send~/receive~ = copy~/paste~ Thus with [copy~ foo] you are taking the incoming signal and copying it to whatever is at the receive-symbol $0-foo, which would be a [paste~ foo] object. The one-to-many connection is that one can copy only one thing at a time (or on systems where you have multiple copy buffers they each have a different key combination or icon on the interface, similar to the way we give a different receive-symbol for each s~ in Pd), but you can paste it as many times as you wish. throw~/catch~ = tobus~/frombus~ I think this one is self-explanatory. However, I'm not sure if "bus" really implies many-to-one (as opposed to many-to-many). Maybe there is a better metaphor. Would love to hear if anyone has suggestions on these names. Thanks, Jonathan * actually I think it's worse than that, because if you see that the control objects s/r are many-to-many, you could reasonably assume that s~/r~ would be many-to-many as well.

Re: [PD] Re : store and manipulate multiple lists

try the matrix object from the iemmatrix lib, you can input each list to a row or column and then you can sort a row or column or even the whole matrix acording to a list "vector" On Wed, Mar 14, 2012 at 7:26 PM, Benoît Fortier <benoitfortier(a)yahoo.ca>wrote: > Thanks Andy.

Re: [PD] Is there a way to block/filter Mathieu ?
by Marco Donnarumma 14 Mar '12

14 Mar '12

with all due respect, I feel your approach Mahatma is feeding war flames here. And I'm happy nobody is picking that up. It's not about hierarchy, and if you would have been participating to the list for longer time you would perfectly know it (and if you are indeed on the list since long, then you easily know that.) I can agree Mathieu and others (me included) can be a bit over the line sometimes, but I find more offensive your comment, than the previous ones. Who gives you the right to publicly ask how to solve your personal issue with an individual thoughts? Who gives you the right to call people "wanna-be-gurus", when this is the ppl that allow you and me to play fancy stuff with a stupid computer. Most importantly, which is the constructive aspect of your comment? Even a "hot" comment on the list is always pointed at creating a discussion, where your discussion is going? If you are not happy, you are completely free to do whatever makes you feel more comfortable. Just do it, ask the administrator, and find a solution to your problem, but putting it out here it's surely counterproductive, and possibly a direct provocation. Your last comment now has a clear provocative tone. You already have the option to filter, delete whatever you like, so please do it, for your and our good sake. This list is one of the best places for thoughts we have on-line. Some of us and myself might overreact sometimes, but it's also true that our communitarian self-criticism (as a list, not as individuals) always brings us back to the real world. openness includes a bit of personal sacrifice imho. > > mahatgma(a)gmail.com, this is your second post to the list, and you're > > already complaining about a member who has been here practically from its > > inception? > > > pull your head in, mate. > > wouv, I was not aware of the strong hierarchy within this community.

sending macosx terminal commands from with pure data
by sonia yuditskaya 14 Mar '12

14 Mar '12

Ahoy and Greetings, I would like to do some text to speech in a pd patch. I am running on Macosx so it seems that there is no version of the ratts external that will run on my system. However macosx itself has very excellent text to speech built in, the only twist is how to send the terminal commands from within pd. Of course actually doing text to speech from within the patch would be prime. Does anyone have experience with either of those scenarios? Sofy Yuditskaya s~ <http://yuditskaya.com>

NetPd status
by Quim Llimona 14 Mar '12

14 Mar '12

Hi all, The Barcelona Laptop Orchestra has been working with some network abstractions built specifically per piece (chats, OSC sync and so). I was thinking on making a whole, reusable framework, but then I read about the NetPd system... I'd like to develop stuff from it (some GUI abstractions, log systems, etc), but it says it's under a transition and so. Does anybody know the current status of the project? Is it usable now, or should I use the old system? Cheers, Quim

vline~ precision, or sequentially segmented playback of a buffer
by João Pais 14 Mar '12

14 Mar '12

Hello list, continuing with a topic I started some time ago (but couldn't continue the discussion), I've made a simulated version of my patch to explain the situation. The full patch is too complex, and would need audio files to be sent with it. The context is as follows: An audio file stored in a buffer is played in small segments in a forward-backward sequence. Each segment is played after the previous, with no gaps in time or reading point. First segment goes as 0 - 8638.86, 2nd as 8638.86 - 17277.7, 3rd as 17277.7 - 25916.6 , etc. All segments are triggered at the same pace, in this case 181.818 ms. You can see all the segments in the [textfile]. Ideally, the original audio file would be reproduced with no difference to the original - besides the playback pointer going forward-backward. But when playing back the segments, after the first initial moment with almost no problems (only the clicks when playback changes direction), clicks start to appear at each segment - from around sample 229K onwards. Since I'm using [vline~], I thought that the timing of the reading point related to the audio blocks wouldn't be a problem. But, if you record the output and look at the audio file, you'll see that the clicks come from a out of phase moment, and then the wave continues. My question is: am I doing something wrong with the circuit? If not, is there an efficient way of achieving a similar playback of a stored buffer? I hope everything is clear. The original patch is a monster, but this version sums up what's happening. Btw, in the original patch all the values are calculated in real time. But with the "recorded" version the audio sound just the same. The original audio file is 5m18s long. Will the be any round-up problems while calculating the segment coordinates to tabread4~? Thanks in advance for who has the time to read this, Joao

When the Going Gets Weird, the Weird Turn Pro [was] Anonymity.
by Julian Brooks 13 Mar '12

13 Mar '12

Ouch - Dominic that ain't nice. Patrick you're nitpicking think/suspect are fairly interchangeable and maybe this is a language/culture thing but it didn't seem that humorous to me. Very admirable and straight apology though (I don't do sarcasm/irony if I can help it). Well, there he goes then - 'who was that dark stranger'. Never really understand what the hell went on between Sevy/Matju, something serious I hope for all the years of wrangling. I put it down to them both having spent too much time coding to have worked on people skills tbh. I think they're both very good at what they do. It should be said that there was a fairly nasty putsch with Degoyan last year but it's noticeable that people are still wanting to make use of his software, thus giving him more opportunity to vent some spleen in the process. And wherever he got the code from is in some sense irrelevant - he spotted things that people would want to use and did it early. It was always good to have someone with that (possibly cliched) radicalism in our midst I thought - a group consciousness extension. I also think some of his points may be hitting home-truths, there is a certain decadence to a lot of our conversations recently - perhaps fiddling while Rome burns? You know I've been meaning to rename one of these posts with "when the going gets weird, the weird turn pro" and maybe now's the time. As for myself, the only comment on this list that feels relevant (and he may not have writing about me anyway) was Jonathan's mention of ruining a good point with bad etiquette (Alex McLean's post on 80c in response to my freakout being a corker). Personally I'm off for some Maoist/Marxist/Leninist purging.

mrpeach routeOSC behaves differently then its previous release?
by Marco Donnarumma 13 Mar '12

13 Mar '12

hello folks, apparently [routeOSC] behaves differently between 42.5 and 43.1 releases (I'm aware mrpeach has been updated in between). I have sliders sending out messages as [list /bla/1/blabli 0.437( with Pd-extended 0.42.5 and the related "older" mrpeach lib, I used to route these messages with [routeOSC /bla] I gave it a try with the 0.43.1 and the "new" mrpeach lib, but now I need to do [route list] | [routeOSC /bla] If the [route list] is omitted, [routeOSC] won't output anything, and it does not complain. it's really a minor fix for the patch, but I'm a bit confused: - was I doing something wrong before? - is this a new feature? - should [routeOSC] tell me something if it can't parse the message? thanks in advance, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.
