@humanpyramids This is great! Congratulations!

line squared shape oscilloscope that triggers sound in gem ?

jameslo — Mon, 12 Oct 2026 18:16:48 GMT

@mosef123 It doesn't (to me), but if you are asking how to generate a stereo sound that draws a square on a GEM oscilloscope when L and R drive X and Y, then here's a way:

cheers
Miller"

Release notes
0.57-0
The "zoom" feature is entirely reworked, thanks to Antoine Rousseau.
[receive] can (at last!) be set to receive from a variable symbol - thanks to Christof and Alexandre
Many new features added to [pointer], [struct], [drawnumber], etc., objects.
After many requests: logical binops such as [==~] and [||~] now included.
IEMGUI number boxes can highlight their image when activated
[clone] object can dynamically allocate copies at run time.
New [siginfo~] object to get sample rate, number of channels, etc.
New [list foreach], [list join] and [list unjoin] objects.
Button to rescan MIDI device list - thanks Ben.
New [snake~ sum], [snake~ pick] and [snake~ split] objects.
Cut/Copy/Paste for patch fragments now work across apps.
Configurable keyboard shortcuts - thanks Iohannes.
[oscparse] object allows non-standard but widely used "double" type.
The [float] object now can parse integers out of symbols such as "preset45.txt".
MacOs "App ID" and "preferences" storage now under info.puredata to agree with website URL.
Incremental improvements to experimental GTK3 front end.
Classes now have a user slot, "c_data" for storing per-class data.
Updates to "find externals" feature - thanks Iohannes.
Much work by Iohannes on the translation infrastructure, and as always, documentation by Alexandre.
And... at long last, '{' and '}' characters are no longer dropped.

Installing pd and confirming the correct directory path resource application

mykeonthemove — Mon, 05 Oct 2026 13:49:23 GMT

@whale-av Thanks David. I would make sense that the apk gets installed on the internal storage and the prefered loaction for the patch files / diirectories would be the sd card. I'll try it and see what happens. Thanks in advance for your reply.

Best Regards
Michael

How would I go about making objects bounce off the window's edges or another object? (Pure Data GEM))

Balwyn — Mon, 05 Oct 2026 09:10:09 GMT

@fussicks this sounds like something I attempted about nine years ago, It may help, but it wasn't very accurate with the collisions

WUESTE MLP — modular groovebox built with Pure Data

johannem — Mon, 05 Oct 2026 07:48:28 GMT

And finally, here’s a video of the patch in action.

But! This is not the elegant way to perform with MLP. The real idea is to enjoy it on its dedicated hardware, with physical controls.

I'm using purrdata for the first time, my question is for add externals do they still go into search path same as pure data ?

@porres I see, I was even trying to open up Live Electronics Tutorial in Pd-L2Ork but didn't work.

"Things I wish I had known when I started Pd"

porres — Wed, 23 Sep 2026 21:17:16 GMT

well, Pd 0.57 is coming out and [receive] now has an inlet, and there's a [list foreach] for iteration

Issue with [netsend/receive]?

jameslo — Tue, 22 Sep 2026 15:03:14 GMT

I figured it out! My last post with a screenshot and instanceIDService3.zip can be made to work with plugdata by replacing [tcpclient] with [netsend -b]. In my previous tests I overlooked that [tcpserver] requires binary mode.

@jamcultur Oh! I didn't know one could change an application's priority, thanks.

Thank you !

How to use shift with arrow keys

jamcultur — Fri, 18 Sep 2026 14:29:10 GMT

Someone on reddit asked how to take different actions when an arrow key is pressed, depending on whether the shift key is up or down. Since I can't post a patch there, I'm posting a sample patch here.

data types in pure data with pd-lib-builder

Ulrike — Thu, 17 Sep 2026 03:47:33 GMT

Hey,
I've been writing small externals in C using pd-lib-builder (as in this tutorial) for a while, all the time not really understanding what on earth is being done with all this object-oriented business I'm writing. All the stuff that comes to and from the pure data environment is in some sort of wrapper data-type shenanigan, i.e. a float that is passed into an inlet of a pd object might be a (t_atom) with symbol "float" or it might be a (t_float) sometimes ?? And in order to interact with any of this I use a getter method, or just treat it as what it should be and cross my fingers (maybe with some forced typing now and then too). I don't like not understanding my data types, and I don't really know what documentation I can look at beyond that git repo I linked above.

anyway I'm just trying to write an object with a construction argument of one (1) float that won't crash Pd when given garbage/nothing on construction.
I'm looking for some kind of check for that it is a ) populated and b ) actually a float.

//constructor called when a new instance is made
void *rms_tilde_new(t_floatarg f) {
    t_rms_tilde *x = (t_rms_tilde *) pd_new(rms_tilde_class);

    //creating a signal outlet
    x->signalout = outlet_new(&x->x_obj, &s_signal);

    //passing creation arguments to internal variables
    x->windowsize = 64;
    if(f >= 1) {
        x->windowsize = f;
    }
    
    return (void *)x;
}

jameslo — Tue, 08 Sep 2026 21:19:37 GMT

@Glop-Glop I'd be lying if I said I understood your question or your patch, but if I were an LLM I'd answer you this way:
Untitled-1.pd
because your original post contained "[random 6]" and "lists" and the patch you posted contained an array with 16 elements, [16( -> [until], and [t b b b]. And because for layout I was trained on @oid's patches.

Mini-album with Pd synth

hansr — Mon, 07 Sep 2026 17:36:24 GMT

@formuls Thanks! The Pd patches for Toetsingen are on https://www.hansroels.be/toetsingen.html

To clarify: I maintain the Mimba synth on github https://github.com/Haroes/mimba It has a stable and 'most recent' version. Additionally, for compositions and performances (like Toetsingen) I have made specific versions of Mimba. So, if you are looking for a documented and more or less 'tidy' version of Mimba, I guess the github stable version is the best choice.
