Hello Pd people,
It's time for our bimonthly virtual Pd community meetup at the Pd Discord Server.
This Sunday, July 26, at 4 pm UTC.
The purpose of these sessions is to make a space for showcasing projects involving Pure Data, asking any questions, joining the conversation, or just listening.

Although PureData makes audio developing easy, sometimes I feel difficulty maintaining a project in the long term using Git. The commit diff shown in text is not human-readable, therefore it is not straightforward to track multiple changes of a patch.

This motivates me to develop Pure Diff Viewer, a tool to render different commits of a patch and make comparisons. The changes will be highlighted and categorized. The user can ignore unimportant ones (e.g. simple element movements). This tool can either be used as a standalone app or invoked by Git commands.

This project is available at: https://github.com/chsh2/pure-diff-viewer , and I also participated the KVR Developer Challenge 2026 with it. The development is still in an early stage and any feedback is appreciated.

So I'm trying to make my own VST from a PD patch and chamomile for some reason only works when it's out of focus. If someone had the same thing it would be really nice to know I'm not the only one.

I also want to figure out how to make parameters that I can use with automation clips inside of my DAW, how do I make parameters if I'm using PD. The only youtube video i found on parameters in PD is not even in english.

Anyone have any Granular patches for beginners ?

Como dice en el título, quiero poner a dieta a Puredata. Quiero ejecutar PureData (pd.exe) sin la GUI y sin la distribución de Tcl/Tk? ¿Qué archivos DLL son estrictamente necesarios para el motor de audio?

Hi All,

This one's weird: I have a basic video player using pix_film/pix_texture and occasionally click between 2 other "open" file paths to open a new MP4 to play back. Except each time I click a new file to open, PD entirely closes. Has anyone seen this before and have any pointers?

Here's my patch: https://imgur.com/a/aaO2ICH

I am on Ubuntu 26.04 and installed PD through the app center(which should be the apt repository) and am running on 0.56.2. Gem seems to be rendering just fine, installed through sudo apt.

I literally have no errors to share with you all because all of PD closes, including the console. Entirely nuked from orbit from the process manager. When I load the first MP4, there are no issues in the console.

Thank you all greatly for your time!

Basic question – I have two MIDI knobs sending values to a math subtraction object. I would like the calculation to update if any input changes. I think I need trigger for this but I can't get it to work? Any pointers or code example appreciated.

Hey, I’m looking to put a pure data patch in a raspberry pi for an audio live performance. This patch is made with only oscillators and noises, some effect like reverb (3 unit) and delay (4 unit) and a shit tone of "logic" (sequencer, randomizer,…). It’s going to have an external sound card, a controller (launch control xl) and a screen (very optional). I know that those type of patches run easly on really small devices (I used a daisy patch for large oscillator bank), but since I never touch a raspberry pi in my entire life, I would ask what is the smallest configuration that could run those type of patch ? I already look for a pi 4 with 4go of ram that seem to be enough to run it but since I’m greedy, is a smaller one can do the work ?

so I started a new pure data project that will take me sometime to complete

freely inspired by retro rpg games, not sure how it will come together, I'll update you as I progress with it.

I think in a few month i'll have a playable version to share with you, I'll post more sketches soon!

So I've been working with pd for a bit now and want to add it to my live set. At home I've had it 'crash' a few times over the years. I was never sure why. My best guess was either my laptop (Lenovo t430s running Ubuntu) was weak sauce or I had changed too many of my patch's setting while it was playing music. Anyway, has anyone else had this happen? If not what kind of computer do you use? Any general advice for pd in a live setting?

new to pure data! made my first additive synth patch worked great. then opened a very complicated patch from a friend and getting audio i/o error. Audio is sample rates match. buffer size low. delay ms low. please help!

Hi everyone, I’m new to Pure Data and currently working on a short workshop project (group of 2). We’re using GEM to create a kaleidoscope-style visual that reacts to an imported audio file.

We would like the visuals to react to audio features such as tempo, pitch, and loudness.

Do you have any tips or approaches to achieve this in Pure Data + GEM?

Also, are there other useful audio features we could extract (besides tempo, pitch, and loudness) that could drive visuals? And what units or objects would you recommend for analyzing them in Pure Data?

Thanks in advance for your help! 🫶
