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.

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

MIDI specifications for Multidimensional Polyphonic Expression (MPE) in Pd
by Alexandre Torres Porres 26 Oct '23

26 Oct '23

some new objects for MPE Midi is on Max's new update, just googled it to see what it was http://expressiveness.org/2015/04/24/midi-specifications-for-multidimension… wonder if you guys know anything about this and if anyone would be into bringing this to Pd. cheers

[PD-announce] ELSE 1, 0 beta 43 with Live Electronics Tutorial is out
by Alexandre Torres Porres 31 Aug '21

31 Aug '21

Hey, it's been 2.5 months without an update, so we have some cool stuff here that I've been teasing about! We have a new gaussian oscillator and gaussian envelopes; Some filter tools that people really liked (conversion from biquad coefficients to poles and zeros, a z-plane plot GUI); and my favorite: [pimpmul~], a phase multiplier/divider that also sends impulses (game changer for me). Of course there's more. My Live Electronics Tutorial had also some important revisions and new additions to reflect the new objects and there's also a pretty cool example that shows how moving average filters work. Details and downloads are here: https://github.com/porres/pd-else/releases/tag/v1.0-beta43 But get it also directly from Pd itself. Total number of objects is now 431, total number of examples in the tutorial is now 440! I need to thank my buddy Matt Barber again with his great help teaching me about the math behind the gaussian function <3 Cheers _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Mobmuplat Menu selection from PD Patch.
by Simon Iten 22 Aug '21

22 Aug '21

As the title says: Can I select a menu item from PD instead of the Mobu GUI? Cannot find it in the docs. Would be nice for presets, so I could save the index instead of the menu item. Cheers

Gaussian Waveshaper
by Matt Barber 18 Aug '21

18 Aug '21

Hi list, I've been looking at the gaussian waveshaper in the [savestate] help file. It's pretty straightforward but I had two questions about it: 1. The bandwidth parameter determines how many standard deviations from zero the "wavetable" contains in order to set the width of the impulse, and vary the number of audible partials. The question is how literally to take the number – is it merely proportional (bw of 1000Hz gives you roughly twice as many partials as bw of 500Hz), or is it more exact (bw of 1000Hz gives you partials roughly up to about 1000Hz)? 2. Is there a reason for waveshaping a sinusoid as opposed to a phasor? It's clear that at transition points between periods you'll be guaranteed a smooth waveform if you use a sinusoid (i.e. the slope won't change abruptly). Is there anything more subtle than that going on? Thanks, Matt

MobMuPlat multitouch and preset saving
by Simon Iten 17 Aug '21

17 Aug '21

For MobMuPlat devs or users… what is the preferred way to receive data from a multitouch GUI object? i.e. send out a bunch of MIDI CC messages according to 3 or 4 fingers x/y position. (two CC messages per finger) i looked at the documentation and i can see the values, but i am stuck at extracting x and y independently for each finger “voice”. i don’t get the magic with [list prepend set] into [list trim], or how i can get a numeric stream (one value per outlet) from it. thanks, and sorry if this question is obvious also, is there a mechanism to save states like in pdparty? saving to a .sav file and recalling later?
