MPE in Pd Vanilla?
by Alexandre Torres Porres 14 Mar '24

14 Mar '24

I'm finally trying to get a hold of what the deal is with MIDI Polyphonic Expression, which is hard because I have no modern controller that uses it. So one question is does anyone know of a nice free open source software that can format, send and receive MPE so I can test some things? Now, only external I found in the wild was https://github.com/pure-data/pure-data/issues/2117 and I'm trying to check it to see how things work. And now for the real subject. I know Pd can get MPE data from raw midi and even specialized objects like [ctlin], but that doesn't seem to me like the "real deal", even though I'm aware my knowledge is limited. I am thinking about a new external for ELSE, but it really looks like Vanilla should handle this. My point and idea is that Pd should better deal with it natively, whatever that actually means, I cannot put things in details yet... for reference, what I can say is that MAX has mpeparse and mpeformat objects, and I figure that Pd should also have something like that, by the way, I also opened an issue on github, see https://github.com/pure-data/pure-data/issues/2117 what do you peple say? cheers

[PD-announce] New Externals for the SoundScape Renderer + ASDF external
by Matthias Geier 31 Dec '23

31 Dec '23

Hi all. We have recently released version 0.6.1 of the SoundScape Renderer (SSR), which is a tool for real-time spatial audio reproduction providing a variety of rendering algorithms, e.g. Wave Field Synthesis, Higher-Order Ambisonics and binaural techniques. Most of the rendering back-ends of the SSR have been available as Pd externals for many years, the Binaural Room Synthesis (BRS) renderer has been added recently. However, the externals had to be compiled manually, which might have kept some potential users from trying them. But now, the SSR externals are also available with Deken! I don't know if I have to explain it on this list, but just in case: go to "Help" -> "Find externals", search for "ssr" and click "install"! Then, put an object [declare -path ssr] into your patch, and now you can use the externals ssr_binaural~, ssr_brs~, ssr_dca~, ssr_aap~, ssr_wfs~ and ssr_vbap~. You can feed audio signals to the externals and use messages to change their positions (and volume etc.). For more details, see the help patches. Alternatively, you can use the brand-new asdf~ external to load a dynamic audio scene using the Audio Scene Description Format (ASDF, https://audioscenedescriptionformat.readthedocs.io/). This will provide the source signals and the control messages for you. Again, just search for "asdf", click "install" and put an object [declare -path asdf] into your patch. Currently, there are not many example scenes available, but for starters you can have a look here: https://github.com/AudioSceneDescriptionFormat/asdf-example-scenes/ This is our first generation of Pd externals via Deken. If you find any problems or if you have suggestions for improvements, please let us know via the issue trackers at https://github.com/SoundScapeRenderer/ssr or https://github.com/AudioSceneDescriptionFormat/asdf-rust. cheers, Matthias _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Relative Db measurement
by Chris McCormick 19 Dec '23

19 Dec '23

Hi, Hopefully this elementary audio question is not too stupid. If I have some signal source how I can I measure the relative change in Db when some change is made to the signal? E.g. if I have an [osc~ 440] going into a [*~] and I change the multiplier, how can I measure the output from that and determine relative change in Db when I change the multiple? Also does this even make sense on Db scale? Thank you! Cheers, Chris. -- https://mccormick.cx/

Examples of dynamic patching

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

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

[switch~] and block computation.
by Lucas Cordiviola 20 Nov '23

20 Nov '23

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.
