Examples of dynamic patching
by Martin Dupras 04 Dec '23

04 Dec '23

I'm still new to dynamic patching, which I've only just started experimenting with. I was wondering if anyone has any neat examples, or tutorials, or videos? Thanks! - martin

alsa crashing on recent Pi OS
by Yann Seznec 04 Dec '23

04 Dec '23

Hi again, I’m wondering if anyone else is having the same issue as me. I’m trying to run Pd patches on Raspberry Pi, and I (perhaps naively) thought that I would use the latest Pi OS. I seem to be having far more issues than I had in the past, namely with alsa crashing. It seems like virtually any patch I run will sooner or later crash and print hundreds of lines of this error: restart alsa output alsa xrun recovery apparently failed Someone on the Pd Forums <https://forum.pdpatchrepo.info/topic/14536/alsa-crashing-on-pi/7> suggested that this could be an issue with the latest Pi OS switching to PipeWire, which seems to make some sense. But before I attempt any fixes, I wanted to see if anyone else was running into this problem or might have some suggestions. Alternatively, can anyone suggest to me a version of the raspberry pi operating system that works well for Pd? Perhaps it will be easiest for me to track down an old OS image and just stick to that. Here are a few more details of what I’m trying, which is ending up with this issue: - Using both a Raspberry Pi 3 and 4 - Installing the latest Pi OS using the official Pi imager. I believe this was slightly different versions for the Pi 3 and Pi 4, but the end result was the same anyway. - I am using the “lite” version so it’s all command line. - installing Pd from the repo (apt-get install puredata). I am not certain what version this is…I think 0.50? - Trying to run a small granular patch like this <https://github.com/yannseznec/humanCall> or a sampler/looper patch like this <https://github.com/yannseznec/soundDestroyer> - I have tried running with a higher block size (up to 1024) thinking that maybe the patches were too intense. This didn’t seem to help. - This is perhaps unrelated, but I did notice that I needed to specify the audio output in the command I’m using to launch the patch. I’m pretty certain this wasn’t necessary in patches I have run on a Pi before. I always get the errors described above. I recognise that this is somewhat anecdotal, but I am really certain that I was able to run much more complicated patches on a Pi several years ago without issue, so this all feels very new to me. Many thanks, Yann

Hello Joseph and everyone, Thanks for the very helpful feedback. I have copied your setup as closely as possible, and the situation seems much improved. I did two things: - install the 32 bit RPi OS 11 Bullseye Full Version on my Raspberry Pi 4. I believe I may have been installing the 64 bit version previously. - compiled Pure Data from source in order to get v 0.54.1 as you described. So far in my first tests I have been able to run a granular patch without any crashes. I also no longer need to specify the audio device in the startup command. Pd will still occasionally print the same error "restart alsa output alsa xrun recovery apparently failed”, but it doesn’t seem to matter. Most of the time it seems to only print it once on launch. Changing the OS and the Pd build at the same time was not a good way to determine exactly what the problem was, of course! So I have not yet found an explanation but this is a promising way forward. It feels likely that the 64 bit OS was the problem. If I figure out any more details I will post them here. As a side note, perhaps someone more knowledgeable than me could update the version of Pd that is currently accessible from apt-get? I didn't mind compiling from source but it is pretty handy to be able to just do apt-get when setting up a new Pi.

Getting position of abstraction in patch
by Thomas Mayer 27 Nov '23

27 Nov '23

Hello, I am trying to find a way to get the position of the abstraction in the including patch from the abstraction itself. Basically when I have stuff like #X obj 13 49 my_abstraction #X obj 58 89 my_abstraction I want to be able to access 13 49 in the first instance of my_abstraction.pd, and 58 89 in the second instance. Is there a way to accomplish it? Thanks, Thomas -- "When one's home has a really excellent computer capable of reaching other computers anywhere in the Galaxy, one scarcely needs to budge."

"espd" play soundfile
by Yogi data 25 Nov '23

25 Nov '23

Hello, after watching a video of a talk given by Mille Puckette at "laboratoire STMS" about "espd" ,which is an adaptation of pd for esp32, I decided to give it a try. I already have a set of 10 esp32 playing sounds from sdcard, using the "arduino-audio-tools library", I monitor esp32's states and trigger samples from my computer using pure data, via wifi. But I would prefer to be able to prototype using pd. The "espd" project compiled nicely, I can upload patches through wifi to my esp32 and all works just fine. But, I couldn't find a way of playing samples, like Miller used it to make did in an art installation so I guess it is possible. My question is : has anyone who has used espd a clue or an example patch showing the usage ? ( I only tried using readsf~ ) Cheers Yog

win11 deken sha256-problem
by IOhannes m zmölnig 21 Nov '23

21 Nov '23

hi, at university we had a roll-out of new Win11 machines, and it seems installing deken packages no longer works as smoothless as expected. downloading works great, but it then fails when trying to validate the sha256 checksum of the package. before i dig deeper: has anybody else experienced this problem? (i don't recall any bugreports) i think a temporary solution is to just disable the SHA256 verification ("Try to verify the libraries' checksum before (re)installing them"), but of course it's better to do a checksum verification. and in any case, i haven't been able to verify yet. fnmds IOhannes

Hi list, There had been some talks on Pd issue "https://github.com/pure-data/pure-data/issues/2134" about "block computation". We are moving it here if there's need to do further talking and clarifications. You are all invited to read it and give any insights. :) -- Mensaje telepatico asistido por maquinas.

MIDI loop
by Chris McCormick 18 Nov '23

18 Nov '23

Hi, Does anybody know of an object (maybe an abstraction over cyclone/seq) with the following properties: * Takes an external MIDI clock tick (like seq). * Stores MIDI events as they happen (like seq). * Can play back recording when ticks start from 0 (like seq). * Can take a message like "loop 64" and it will then loop the last 64 beats worth of messages it has stored from the moment it is pressed. Hm, actually this sounds like a very small abstraction over seq maybe I should just build it? I have an audio rate version of this which just records a constant loop to a table but I want a MIDI version. Thanks for any input! Chris. -- https://mccormick.cx/

Eh, I pulled the git history from iem to GitHub but then was *strongly* asked not to develop it further / that it was broken / etc etc. I left it but should probably remove the repo... it would be better to use/make a different solution. > On Nov 17, 2023, at 12:00 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Fri, 17 Nov 2023 08:12:21 +0100 > From: "Peter P." <peterparker(a)fastmail.com <mailto:peterparker@fastmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: Re: [PD] MIDI loop > Message-ID: <20231117071221.ly7sqlrl56w5nfeg(a)fastmail.com <mailto:20231117071221.ly7sqlrl56w5nfeg@fastmail.com>> > Content-Type: text/plain; charset=us-ascii > > * Chris McCormick <chris(a)mccormick.cx <mailto:chris@mccormick.cx>> [2023-11-17 04:29]: >> Hi, >> >> Does anybody know of an object (maybe an abstraction over cyclone/seq) with >> the following properties: >> >> * Takes an external MIDI clock tick (like seq). >> * Stores MIDI events as they happen (like seq). >> * Can play back recording when ticks start from 0 (like seq). >> * Can take a message like "loop 64" and it will then loop the last 64 beats >> worth of messages it has stored from the moment it is pressed. > > Witout checking its specs myself you might want to look at Kristof > Czaja's [xeq] which no longer lives at > http://suita.chopin.edu.pl/~czaja/miXed/externs/xeq.html > but was forked to > https://github.com/pd-externals/xeq > > cheersz, P -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
