[random] and seed value
by Thomas Mayer 16 Dec '22

16 Dec '22

Hello, currently [random] uses a fixed value for initialisation. This leads to the same sequence of values all the time. https://github.com/pure-data/pure-data/blob/c0cd34924a50bdd1cc37dfb6b01f9be… My guess is, that most users probably expect at least different seed values every time. Maybe the help file should explicitely state the behaviour or a different way for deriving the initial seed should be used, e.g. taking the local time. Or a better PRNG could be used as well. If we take the solution to initialize [random] with a different seed each time, an explanation on how to revert to the old behaviour of a seed value of 1489853723 should be mentioned in the help. I could tackle that, but would like a discussion about that before coding. Thanks, Thomas -- "Prisons are needed only to provide the illusion that courts and police are effective.

Why sliders width changed?
by José de Abreu 15 Dec '22

15 Dec '22

Hey list, this is more of a curiosity question. Sliders used to have 128 of width, and with a default range of 0 to 127 it allowed the slider only to make "integers" as output. Now, new sliders have 170 of width and the same o to 127 range. Then each step isn't of size 1 anymore... So just for curiosity, why did this change?

To Pd-announce: Pd version 0.53-1 is available from http://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data I have access again to my old Mac so I was slao able to bring the macOS7 64- and 32-bit apps up to date. cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

[PD-announce] pd 0.53-1test1 released
by Miller Puckette via Pd-announce 13 Dec '22

13 Dec '22

To Pd-announce: Pd version 0.53-1test1 available from http://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data . I've already updated the translations since then, so no worries about that (I think). Otherwise, as always, if anything seems broken you can let the pd list know, or write me personally. I'll plan to finalize pd 0.53-1 later this week. cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

is [sigmund~] a "phase vocoder"?
by Alexandre Torres Porres 12 Dec '22

12 Dec '22

Hi, just get things straight and confirmed, for quite a while now I have included [sigmund~] into a "phase vocoder" section of my tutorial. I never check and I'm just guessing it uses what is called "phase vocoder analysis" to find accurate pitches and that can be used in a bank of oscillators and I see that a so called "phase vocoder" is also used for reconstructing signals with an oscillator bank. Who could confirm or deny this? :) Please point me to references if you can. Thanks

[date] and [time] in vanilla, was [random] and seed value
by Dan Wilcox 12 Dec '22

12 Dec '22

Actually, what I meant is that I'd like a date/time object in vanilla in general, not because I need it for a random seed, but because I generate time stamp strings for recordings. > On Dec 12, 2022, at 7:07 AM, pd-list-request(a)lists.iem.at wrote: > > Vanilla could also have something like [date]/[time] one way or another, > but adding it just for the case of managing seeds in [random] seems like a > bad idea to me. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD] [random] and seed value
by Philip Stone 12 Dec '22

12 Dec '22

Hello all, I don’t think anybody is advocating for this, but I just wanted to be sure that whatever changes are made to [random], the ‘seed’ message capability is maintained. My music very much depends on the ability to control the seed value and get a repeatable ‘random’ sequence. Where I need a truly random seed, I loadbang a [timer], and then have an ‘Init’ button that initializes all of my system. At that point, I use the value from the timer to seed [random].

sonogram abstraction idea with data structures.
by Alexandre Torres Porres 12 Dec '22

12 Dec '22

Hi! I wanted to implement a sonogram analysis like max's spectroscope~ does (see picture) with FFT analysis and data structures. Any ideas? I guess I can [fft~] connected to a [tabsend~] and then have a [bang~] reading the table values for generating the graph, that's my first guess. But I am also now inspired by partialtracer.pd from the data structures tutorial, which uses [sigmund~] and it'd be great if it had a new output mode for raw FFT amplitudes, I am assuming that the 'peaks' output doesn't really work for this, or would it? cheers
