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

Preset management for Pd Vanilla
by Alexandre Torres Porres 13 Nov '23

13 Nov '23

Never really needed fancy preset management other than storing messages in a basic vanilla way. But I've seen people mention how Pd lacks a nice preset system. Not that I know what a fancy one actually needs since I never felt the demand. So I'm here to ask what people use in Pd Vanilla, be it a pure vanilla solution or an external. And also to ask what people miss. This is what I came up with as a pure vanilla abstraction, it's based on [text] and [savestate]. Here's the thing: https://drive.google.com/file/d/1A0ISEJo5F1E578WHM1doo1n2CJAthonU/view?usp=… In short, the preset abstraction takes messages and stores them. You can have many of these on your patch and use them to recall presets for any parameters. It takes any kind of messages. I'm making use of built-in sends and receives in the number boxes to make the patch cleaner. Just think that you can have separate control of each parameter having its own preset or group all of them together globally, or a group here and another there, whatever... Once you save the patch, the presets you saved get stored in the patch. As for my current idea for my ELSE library, I'm using an object similar to grab to take messages from [receive] objects. It's a development over this original vanilla abstraction. My first draft is this, I hope that sharing the screenshot give you a nice idea. [image: Screen Shot 2021-01-21 at 04.47.42.png] You can check what's up in my repository for more details... https://github.com/porres/pd-else/blob/master/Classes/Abstractions/preset.pd cheers

[PD-announce] cyclone 0.8-0 is out
by Alexandre Torres Porres 08 Nov '23

08 Nov '23

Hi, it was supposed to be a minor bugfix release but I went ahead and made some objects deprecated. They're still there for backwards compatibility, patches will run, but annoying errors will show up. Such objects include minimum~, maximum~, pow~, clip~, which have Vanilla versions. Others are number~ and comment, a couple of GUI elements that never really worked well and were mostly used in the documentation (so yeah, I also revised the documentation). That's basically it and all folks. see https://github.com/porres/pd-cyclone/releases/tag/cyclone_v0.8-0 get it also via deken. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

soundtouch~ for Pd Vanilla
by Alexandre Torres Porres 31 Oct '23

31 Oct '23

Hi folks, I'm on a vibe of uploading missing libraries and objects for Pd Vanilla on deken. On the list I have FFTease, Lyonpotpourri, CICM-Tools and more stuff that I'm looking into, just so you know... Now, I see there's an old soundtouch~ external here: http://www.katjaas.nl/pitchshift/soundtouch~.html - it's "version 0.9" by Katja Vetter. It was developed with SoundTouch version 1.6 and Pure Data version 0.42. I tested on Pd 0.51-4 32 bits on mac and it works fine. There are binaries for download on the link above, but not for 64 bits. I wonder if anyone wants to help me build these with pd-lib-builder and all. Now, the ceammc librarym (and Pd-ceammc distribution) has a soundtouch~ external too. It's the same name, but not the same external, this one is marked as "version 0.1". So we do already have "a" soundtouch~ for vanilla, but I wanted to also get katja's external up there. So I just uploaded the download from that page here https://github.com/porres/pd-soundtouch - It's just the download as it is and we need to change to hopefully use pd-lib-builder, which would make things easier. I did try that and it didn't work. So, anyone onboard with this? cheers

Re: [PD] MPE in Pd Vanilla
by Sam Ross 27 Oct '23

Hi there, I have a Linnstrument since earlier this year and am currently using pure data to create a kind of framework to interface with its 'user firmware mode'. (The idea being people can then make their own modules using the framework (sequencers, arps, etc) without having to get into Arduino programming, and that maybe if other Linnstrument users find it useful collaboration will happen.) Since getting my head around how midi (1.0!) works, with the status bytes and running status and all, I have found parsing the vanilla midi-in object quite straightforward. Like you say, the only thing the vanilla objects don't handle is release velocity. As far as I am concerned sending MPE is quite simple: you just send x=pitchbend, y=timbre (normally cc74), z=channel aftertouch (poly is redundant in this context), but *on a note-per-channel basis*. You also tend to assign a channel (i.e. 1) for omni messages, else send them over all redundantly. I've just followed the advice on Roger Linn's site here: https://www.rogerlinndesign.com/support/support-developers-how-to-add-mpe I've also been fiddling around with an 'MPE-izer' that basically uses a cloned instance of vstplugin~ (itself nested inside an abstraction, and set with the plugin I want to clone) to send note-per-channel to each clone, and that works fine. The really fiddly stuff is dealing with the sensor data of the Linnstrument, but sending MPE is as straightforward as normal midi messages, except on a note-per-channel basis. For my part I don't really have anything ready to release yet and reckon you guys are more advanced than me (thanks for Else btw, Mr Porres, it's great!) but if you want a look at my MPE-izer or anything just let me know. I'm a big fan of MPE, mostly because it allows me to feel more connected to what I'm playing - I'm not a great player but that feeling of connection is worth worlds. You can get it just from expert knob twiddling if you're in the zone but still... viva vibrato?

Hey Simon, looking back on old messages here on the list. Do you know any modern controller with release velocity which is not part of MPE? I suspect this is coming back as a thing now for MPE controllers. cheers

tcpsend disconnects
by Csaba Láng 26 Oct '23

26 Oct '23

Hi list, I am struggling with this for many years, and looks like cannot solve the issue of the tcpsend object which disconnects by itself. Would be easy to reconnect if I had an outlet with the info if connected or not like netsend has. Is there any solution to keep it connected stable? Any hints welcome. Best, Popesz
