Hey Anselmo, Here's the Digital Waveguide Synthesizer (string model) I promised you at pdcon16~It's actually a hack of Kim Taylor's original patches posted to the pd-list I-can't-remember-when. Enclosed is the original folder which also has two different pluck excitations and one bow excitation.It's quite CPU intensive - more so than a Karplus-Strong model, but it's really powerful. Kim also included a readme.html page with some theory on how it works, and a reference to the original Julius Orion Smith paper from Stanford.Anyway, have a play. My version has a tendency to produce more inharmonic tones, but a more authentic string synthesis is found in Kim's DEMO1.pd and DEMO2.pd files.

abl_link~ external for windows
by Jean-Yves Gratius 24 Nov '16

24 Nov '16

Hi Peter, hi list, Today I succedeed in compiling abl_link~ for windows. Documentation will come later. I couldn't use makefile, I created a code:blocks project with VC++2015 standalone compiler, with some changes into files. https://sourceforge.net/projects/jygsdownloads/files/abl_link%7E4windows/ Sync tested with puredata metronome patch and ninjaJamm android app, seems to work. cheers, Jean-Yves Gratius

Next PdCon?
by Alexandros Drymonitis 24 Nov '16

24 Nov '16

Hi list, Since we talked about this at the Convention, I asked a friend and colleague who works at the American College of Greece in Athens whether it would be possible to host the next Pd Convention there. He is very positive about this, without this meaning it's certain. What I would like to ask is when do you guys think it would be best to organize this? 2017 or 2018? I guess both years would work fine for us (my colleague and me), but maybe a convention in one year would be a bit of an overkill. FYI, the college can provide the necessary infrastructure (well, maybe there's no room with eight or sixteen speakers, but there's at least a quad PA and a studio, and rooms to host paper presentations and workshops - have to check in more detail as to what is available there) for the most part. Some other stuff (like concerts) can happen in various places in Athens. The thing is that the college is in the northern suburbs of Athens, and anything else will probably happen in the center. I know that PdCon16~ was a bit scattered around NYC, and Athens is much smaller than that, but transportation is not the best. Not really sure if that's a problem though. I mean, if Athens is the only candidate for the next convention, I wouldn't see this as a problem. If there are other candidates, it might be something to consider (I'm pretty sure few places would beat the weather we've got here though!). Any advice on organizing a Pd Convention is very welcome. As I already wrote, it's not certain that it will happen in Athens, but it's quite possible.

Re: [PD] Installing externals on Raspberry Pi 3
by David 24 Nov '16

24 Nov '16

Thanks, I found most of them and was able to install them. I'm still missing two that don't seem to be in the repository, 'creb' and 'flatgui'. Maybe they're no longer supported by anybody. Any idea if they might be in some other repository?

[delwrite~], or "what Pd operations are/should be realtime?"
by Matt Barber 24 Nov '16

24 Nov '16

Hi list; thanks for a wonderful PdCon (to Stevens and NYU people especially). I had a quick chat with Miller after the "future of Pd" discussion. I told him there is one feature I've heard Pd users ask for many times: a "clear" method for [delwrite~]. A [delwrite~] resize method is something I've heard brought up a number of times as well, but I didn't mention it. Each of these has a runtime cost that could disrupt the realtime dsp calculation. Clearing a [delwrite~] is a linear-time operation, and for long delay lines it could cause audio dropouts; resizing is more problematic because it's not clear what to do with samples already in the delay line – probably it would need to be cleared as well, which would take even more time (although there is already an indirect resize function when sample rate is changed). On the other hand, Pd arrays can be resized and cleared (const 0) ad libitum, which is more or less the same operation. We usually tell users 'do this at your own risk when computing audio.' So what is the main difference? I think it's that [delwrite~] is a tilde object that is supposed not to cause dropouts on its own. If clearing it could cause a dropout, there are reasons for thinking of that as a bug rather than simply a risk. Is there a compromise procedure? We could add an option to spread the clearing out over time. For instance "clear 5000" would mean "clear the delay line over the next 5000 ms." A second argument would let the user choose whether to preferentially preserve the most recent samples or the oldest samples. Given only a time argument, default would be to preserve oldest samples (less work has to be done overall since the write pointer would also be filling the line with zeroes). Without a time argument (i.e. "clear" with no arguments), the default would be to clear it immediately with the understanding that there could be a possible dropout. A broader topic for another time would be "what Pd operations are/should be realtime, and which are best at load time?" Thoughts? Matt

Installing externals on Raspberry Pi 3
by David 24 Nov '16

24 Nov '16

> > Hi! I have PD v0.46.2 installed on a RPi3 under Jessie. I'm trying to install some externals by using 'sudo apt-get install pd-<insert name here>', but I'm just getting "Unable to locate package ...". There was a posting on the raspberrypi.org forum saying that this method worked, but the posting was a little old. Is this the best way to install externals on a RPi? Is there a repository I need to add to find them? The latest version of PD available in the Raspian repositories is v0.46.2. Maybe I should install v0.47, but where can I find it for the RPi? Thanks, David.

It's really clever, and I don't think it screws anything up on the outside. This is a technique I'd never thought of, and I can imagine some interesting things coming from this (though I'm not sure it's a canonical technique or incidental). There are some things to think about, like whether the [inlet~] vector is cleared or if it just keeps the last 64 samples for each iteration of the [until] loop. > My patch will not work in environment using blocksize != 64 but it could be fixed by querying current blocksize. it could also be optimized with an increase of the subpatch blocksize during the clear process in order to reduce the until loop. anyway, things can always be more optimized, but I don't thinks they always need to be more optimized. > > > I'm just talking in general about the idea of amortizing the cost of the operation > across multiple blocks, which I assume is what's happening in his abstraction (or > at least what's supposed to happen). my patch is not amortizing the cost of the operation across multiple block, but this could be done easily. > > Hm... > In practice, how do you find Pd-l2ork's "clear" method compares to Cyrille's abstraction? Pd-l2ork "clear" works only on pd-l2ork. my abstraction work on all pd variant. ;-) cheers c > > -Jonathan > > > _______________________________________________ > Pd-list(a)lists.iem.at mailing list > UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list >

by Alexandre Torres Porres 24 Nov '16

24 Nov '16

Howdy, just put up the latest snapshot of our cyclone 0.3 update project at: https://github.com/porres/pd-cyclone/releases/tag/0.3prealpha5 Perhaps someone could do a windows binary for us like the last time? Lucas? By the way, there'll be streaming of the paper sessions tomorrow and we're scheduled to go live around 11am (new york time), here's the streaming: http://www.nyu-waverlylabs.org/pdcon16/ cheers
