pdmax - error on Mac
by João Pais 15 Jan '22

15 Jan '22

Hi List, I sent a patch to someone on a mac, and they had a problem with the pdmax external: "pd~: could not load due to incorrect architecture". Is there a way to avoid this problem? The system is a MacBook Air M1 Monterey 12.1. (I tried the patch on another mac with an older system, and it worked) Best, Joao

Modulo function in [expr]
by Hrvoje Radnic 14 Jan '22

14 Jan '22

Dear List, It looks like the mod function inside the [expr] object does not work, or I am using wrong syntax. In the help file for [expr], there is a reference cheat sheet which say that the object should support it, but I can't figure out how to do it. Anyone has an idea how to solve that? Thank you! Hrvoje Radnic

Made with FluCoMa: Double launch today!
by Pierre Alexandre Tremblay 14 Jan '22

14 Jan '22

Dear all We are happy to announce two new strands for inspiring thoughts and musics, intertwined with FluCoMa (ab)use today. Most of them highlight the Max and SuperCollider API but it is exactly the same in Pd so these ideas and patches can be translated. Firstly, a preview of the seven pieces premiered last summer, remixed and re-edited by Angela Guyton. A short clip to show an overview of what ties in all the works together. We plan to release a piece every other week, starting next week with the duet of Alice Eldridge and Chris Kiefer. Watch it here: https://youtu.be/6p_R2pVSMVg Secondly, a new series of “Made with FluCoMa" articles where @jacob.hart explains and showcases the relation between the musicking, the underlying thinking, and the creative coding. To start with a bang, we release two today: Oliver Pasquet ( https://learn.flucoma.org/madewithflucoma/pasquet) and Lauren Hayes (https://learn.flucoma.org/madewithflucoma/hayes), and plan to release a new one every other week. I hope you enjoy them. We'll update this thread with new releases as they come. p

Store data in memory more efficiently than in arrays
by Roman Haefeli 14 Jan '22

14 Jan '22

Hi Sometimes I stored byte data (lists of bytes) in arrays. IIRC, I read once in IRC that one value in a Pd-array requires not 4 bytes, but 8 bytes on 64-bit systems. Since storing plain bytes seems not such an uncommon use case for me, I wonder if it can be done more efficiently. Not that I ever hit a memory limit, I'm just curious. With the new (amazing!) [file] object, dealing with byte lists has become even more appealing, so the desire to store them in memory increases. Roman

permute lists?
by Peter P. 14 Jan '22

14 Jan '22

Hi list, i am trying to get random permutations of the elements of a list. The mailinglist archive gives some results using largely externals from about twenty years ago, I wonder if any internal object can do that by now? Thanks for all pointers, P

Arbitrary buffer sizes in pd, libpd
by Max 13 Jan '22

13 Jan '22

Apparently some applications on some OSes allow the user to set any buffer size in their audio settings. Sometimes the buffer size will be a slider to set any value small to large. One user of our VST3 plugin running libpd inside complained about sporadic crackles and discontinuities in the audio. The user was running the plugin in Reaper on the Mac with a buffer size of 1200. It never even occurred to me to even test other buffer sizes than 64, 128, 512, 1024. However apparently Reaper allows these settings and they will lead to discontinuities since Pd and therefore libpd aren't prepared for such arbitrary buffer sizes. We could add more ring buffers in our plugin code, but this would introduce latency for everyone else. Just wanted to share this here, since it is something to consider for libpd implementations. m.

irreversibly high CPU usage with 'use callbacks' (macOS)
by William Chang 12 Jan '22

12 Jan '22

Hi all, If I turn on 'use callbacks' in audio preferences, then turn on DSP, pd's CPU usage goes to > 100% and stays there even if I turn DSP back off. This sometimes locks up the GUI and I have to restart Pd. Without checking 'use callbacks' it seems to be fine. Tried this with default audio devices, MOTU Ultralite mk4, and Blackhole 2ch. Can anyone reproduce? Pd: 0.52-1-really macOS: 12.0.1 MacBook Pro 14" M1 Pro Thanks, Will

[deken] new feature : download a list of externals
by abel.jerome＠free.fr 12 Jan '22

12 Jan '22

Hi, Thanks for Deken development, it is really helpful. I wonder if it would be possible to add a feature to deken, like : "download a list of externals" or show a window with checkboxes per lib. It could be very useful in workshops to use few libraries with students. So download them once. Best, ++ Jérôme http://jeromeabel.net

Re: [PD] More adventures in [file] land - spaces in paths
by Christof Ressi 12 Jan '22

No worries! Actually, your question really shows how the current behavior of symbol atoms can be confusing and why it needs to be fixed.

More adventures in [file] land - spaces in paths
by Pierre Alexandre Tremblay 12 Jan '22

12 Jan '22

Hello Did anyone have problems with spaces in paths? If one uses the help to demonstrate, entering the path (don’t worry this is not my real path :) /User/pa/my\ hard\ disk/my\ files/test.pd One gets at the bottom: /User/pa/my\\\ hard\\\ disk/my\\\ files/text.pd === If I investigate the list length I get the right number of components which mean that [path split] is working great of keeping the space escapement So I reckon it is a ‘bug’ in [file join] ? Or is it an expected behaviour?
