patching feedback loops in parent patch
by Clemens 16 Nov '23

16 Nov '23

Hello there, I noticed that pd handles delayed feedback loops a little bit odd. Feedback loops seem to be only allowed within the sub patch that contains the delay as well. When I patch the feedback loop in the parent of the patch that contains the delay, pd complains with the usual error message and doesn't give me audio output. The screenshots below illustrate the issue. No problem in this case. Everything fine. I would argue this patch is functionally equivalent to the one above, but it refuses to run. Is this behavior intended?

[PD-announce] ELSE 1.0-0 rc10 and live electronics tutorial released
by Alexandre Torres Porres 15 Nov '23

15 Nov '23

Howdy, a quick update I needed to make in the middle of a course and to settle the ground for a project I'm unveiling this week in a symposium (the first draft of my modular abstractions). One new thing I have is a great gift from Tim Schoen, he just gave me this incredible object named [circuit~] that emulates analog circuitry. I'm blown away and have no idea how it works, it's just pure magic as I see it. As an atheist, I can't explain it... Tim also helped in a compild version of [conv~]. I had this very expensive abstraction and this is now a much more simplified version of the great william brent's [convolve~] object. This was one of the things on my list for a final release, so we're getting closer. By the way, I think I've said it before, I'm planning a final release next year when Tim's Plugdata reaches version 1.0 (phew, finally). I'm still extendind the MC awareness of objects in ELSE. The [sine~] , [imp~] and [adsr~] objects are now MC aware! The [adsr~] and [envgen~] also got a new audio inlet for retriggering with impulses. Including new objects, ELSE now has 70 signal objects that can deal with multichannels. A family of new objects I'm really proud of is [pm6~], [pm4~] and [pm2~]. These are 6, 4 and 2 operators synths with a modulation matrix for phase modulation. So yeah, think of DX7 and stuff. Or Native Instruments' FM8, actually. This is beautifual, and MC aware! Being MC aware makes it polyphonic with [voices~], without the need of [clone]. Did I mention I'm working on modular abstractions? Yup, one based on [pm6~] is done, and looks great with all the GUI there for you to set values in the modulation matrix, plus panning, detuning, ratio. Really damn proud of this one. A new [mono~] object offers monophonic voice management with signal rate portamento output. A [mpe.in] object is my first take on managing MIDI Polyphonic Expression. I guess that's the highlights and it for now. Current object count is: 518 (277 signal objects and 241 control objects)! 299 coded objects (192 signal objects / 107 control objects) 219 abstractions (85 signal objects / 134 control objects) Not much new in the tutorial, just some updates and revisions to add the new objects and breaking changes in ELSE. Total number of examples is now 508! More details in https://github.com/porres/pd-else/releases/tag/v.1.0-rc10 Get it from there or deken (no raspberry pi yet). Expect this one soon in a next PlugData release. cheers _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Preset management for Pd Vanilla
by Alexandre Torres Porres 13 Nov '23

13 Nov '23

Never really needed fancy preset management other than storing messages in a basic vanilla way. But I've seen people mention how Pd lacks a nice preset system. Not that I know what a fancy one actually needs since I never felt the demand. So I'm here to ask what people use in Pd Vanilla, be it a pure vanilla solution or an external. And also to ask what people miss. This is what I came up with as a pure vanilla abstraction, it's based on [text] and [savestate]. Here's the thing: https://drive.google.com/file/d/1A0ISEJo5F1E578WHM1doo1n2CJAthonU/view?usp=… In short, the preset abstraction takes messages and stores them. You can have many of these on your patch and use them to recall presets for any parameters. It takes any kind of messages. I'm making use of built-in sends and receives in the number boxes to make the patch cleaner. Just think that you can have separate control of each parameter having its own preset or group all of them together globally, or a group here and another there, whatever... Once you save the patch, the presets you saved get stored in the patch. As for my current idea for my ELSE library, I'm using an object similar to grab to take messages from [receive] objects. It's a development over this original vanilla abstraction. My first draft is this, I hope that sharing the screenshot give you a nice idea. [image: Screen Shot 2021-01-21 at 04.47.42.png] You can check what's up in my repository for more details... https://github.com/porres/pd-else/blob/master/Classes/Abstractions/preset.pd cheers

Current best practice for GPIO pins on Raspberry Pi?
by Yann Seznec 10 Nov '23

10 Nov '23

Hello, I’m wondering what the best option is nowadays for using the GPIO pins on a Raspberry Pi in Pure Data. Wiring Pi seems to be no longer available, as far as I can tell. I’m not sure what other options there are? One option suggested elsewhere for inputs was to use the “retrogame” script to turn GPIO pin activity into keyboard presses and use the [key] object in Pd, but I can’t seem to get that script to work properly yet. Any suggestions would be great, thanks in advance. Yann

[PD-announce] Speculative Sound Synthesis - Call for works
by David Pirrò 09 Nov '23

09 Nov '23

[Apologies for cross posting] Speculative Sound Synthesis - Call for works Speculative Sound Synthesis is inviting submissions of experimental works in the fields of computer music, electronic, music, and sound art. We are seeking artistic works which question, challenge, criticize, deconstruct, re-compose, re-formulate, shift, dis-place, endanger or reject established standards in sound synthesis. Speculative Sound Synthesis is an artistic research project by David Pirrò, Luc Döbereiner, Ji Youn Kang and Leonie Strecker. The project is funded by the Austrian Science Fund FWF and based at the Institute of Electronic Music and Acoustics (IEM) at the University of Music and Performing Arts Graz, Austria. The project challenges established patterns of interaction between technology and artistic practice. While standardized processes in computer music are analyzed, destabilized and reshaped through speculation, the project’s central aim is to create spaces for new aesthetic potentials in the practice of experimental music. https://speculativesoundsynthesis.iem.sh Applicants should send a proposal for an artistic work: i.e. an electroacoustic or acoustic composition, an installation, a piece of software, a live-performance, a text, or any combination thereof. The proposed work should display aspects of artistic research by making the scientific, philosophical, technological or artistic aspects, choices and references explicit in whichever form the artists might deem suitable. In order to share their work with the artistic research community, during their working period artists will be asked to document their working process and its results in an appropriate form. The three selected artists will each receive a commission of €3000 for a new work to be completed during two consecutive months in 2024 (exact dates to be discussed individually). During this time, they will be an active part of the ongoing artistic research project Speculative Sound Synthesis and will discuss and exchange ideas with its team. Furthermore, they are offered the possibility to present their work/research in a public concert or lecture at the IEM. How to apply: Please send us your application via email at specu...(a)iem.at including: - a project proposal (500-1000 words) - 2 to 3 links to examples of your work - curriculum vitae - availability in 2024 and preferred working period Deadline: 31st January 2024 More information about the project can be found on our website: https://speculativesoundsynthesis.iem.sh For any question, please contact us via specu...(a)iem.at We are looking forward to your application! “Speculative Sound Synthesis” is funded by the Austrian Science Fund FWF (PEEK AR 713-G) _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Separation of concerns
by Dafydd Hughes 09 Nov '23

09 Nov '23

Hey all Long time! I hope you’re well. I’ve recently found myself wanting to use a performance patch which consists of a bunch of graph-on-parent abstractions I’ve built on both my laptop and a Raspberry Pi with a small touchscreen, and am of course finding the laptop versions impossible to use on the Pi. I figure the best approach is to write a backend abstraction for each, then multiple UIs that I can swap out depending on the situation. Has anyone here done this? Would you be willing to share your work or some tips? I started the job last night and I’m having some success, but wonder if I’m missing some really obvious patterns that would make the whole thing more elegant/usable/less likely to fall apart in performance. Cheers Dafydd
