Scaling problem
by Allister Sinclair 24 Aug '20

24 Aug '20

Hi, So the short version of my question is: PD is tiny on my system, what can I do? I have a Xfce desktop on a small laptop with HD screen (1080). Everything is tiny because not scaled properly, but I can make it okay by changing dpi size. This makes everything okay except puredata... Puredata is still tiny, I'm guessing because of Tcl/Tk. This is a problem because if I just change the font size it messes up all my tidy patches (hundreds of them) plus it doesn't take effect on graphics. The zoom factor is either 1 or 2. 2 is huge. I wish there was some way to do fractional scaling. Do you know a workaround? In gui plugins maybe? (I wouldn't know how to program a plugin to change that), or is this behavior hard-wired to pd? Thanks -- Allister

[PD-announce] Cyclone 0.5-3 released
by Alexandre Torres Porres 22 Aug '20

22 Aug '20

Cyclone 0.5-3 is out, needs Pd 0.51-0 (but 0.51-1 is out and you should get that). It's available via Pd. Most of the work is still in getting cyclone/comment "awesome", like now we draw an outline when in edit mode and added support for foreign alphabets. It still needs a better properties window and hopefully we'll get there soon. There's also other stuff in this release. Find full changelog and binaries here: https://github.com/porres/pd-cyclone/releases/tag/cyclone_0.5-3 (binaries also available via Pd's 'deken'). Cheers. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

[PD-announce] ELSE 1.0 Beta 30 with live electronics tutorial is out (needs Pd 0.51-1)!
by Alexandre Torres Porres 18 Aug '20

18 Aug '20

Hi, this needs Pd 0.51-the highlight is a new abstraction called [batch.rec~] that records your patches into a sound file in batch mode. In this way you can render whatever amount of audio as fast as possible in your computer. This is possible with the new 'fast-forward' message to Pd, available in Pd 0.51-1. The cool thing about this object is that it has multichannel support. The "Live Electronics Tutorial" is part of the package and relies on the ELSE library. Find this folder inside the 'else' folder, check its readme. The tutorial also provides an example on how to use this new 'fast-forward' feature. Check "Vol.1/Introduction-Pd.Quickstart/2.Syntax/4.fast-forward.pd". Find downloads for basically every platform possible now (there are 4 different ones for raspberry pi only) at https://github.com/porres/pd-else/releases/tag/v1.0-beta30 - Check also in this link more CHANGELOG details. A Changelog for the tutorial is here https://github.com/porres/Live-Electronics-Tutorial/releases/tag/v1.0-beta-… You cal also download this directly via "Pd => Find Externals", just search for 'else', it's already online! _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

A related note: PdParty on iOS supports a ".pdz" but it's just a renamed zip file, similar to the original RjDj ".rjz. file. > On Aug 17, 2020, at 1:25 PM, pd-list-request(a)lists.iem.at wrote: > > If you want to pack pd projects in a "pd format", don't forget all other > files that belong to Pd projects - sound, midi, text, images, video, ... > Is it worth it to re-invent a pd-zip format when zip already exists and > is ubiquitous? -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

[PD-announce] Pd 0.51-1 released
by Miller Puckette via Pd-announce 17 Aug '20

17 Aug '20

To Pd-announce: Pd version 0.51-1 is available on http://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data. This contains bug fixes, notably fixing problems running on Macintoshes after dark or on system 11. [OT] another announcement, but nothing to do with Pd: a new book that Kerry Hagan and I edited about electornic music pioneers, "Between the Tracks", comes out Sept. 1 from MIT Press. cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Do you have any GUIs in the chain? I'd remove all GUI objects which are being updated live, ie. a number atom between two objects, etc. Constantly updating the GUI when not really needed can slow you down... > On Aug 16, 2020, at 3:25 AM, pd-list-request(a)lists.iem.at wrote: > > Date: Sat, 15 Aug 2020 22:01:52 +0200 > From: iftah gabbai <ift.gab(a)gmail.com <mailto:ift.gab@gmail.com>> > To: Pd-List <Pd-list(a)lists.iem.at <mailto:Pd-list@lists.iem.at>>, Simon Iten <itensimon(a)gmail.com <mailto:itensimon@gmail.com>> > Subject: Re: [PD] recording 192khz > Message-ID: > <CA+d=bQKuZuCHgwFN3uXAs=5Xo9o=5w+2=j06n9m8zP8YdVt9BA(a)mail.gmail.com <mailto:CA+d=bQKuZuCHgwFN3uXAs=5Xo9o=5w+2=j06n9m8zP8YdVt9BA@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > i think i tried it (if i understand correctly), i started jack with rt prio > and added the -jack tag to pd and it didnt work, just for test sake i tried > a simple python script using pyaudio and recorded 10 min of 2 ch 192khz > 24bit with no prob so im narrowing this down to pd misbehaving somehow? -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Advice on creating an external object for controlling a DAC breakout board
by Alexandros 16 Aug '20

16 Aug '20

I want to create an external object to control a quad DAC board with a Raspberry Pi, namely this <https://learn.adafruit.com/adafruit-mcp4728-i2c-quad-dac> one. As the object should run at signal rate, I'm confused as to how I should control the rate of values sent to the DAC. Since all signal objects in Pd work on DSP ticks, processing as many samples as the block size as fast as possible, how should I go about sending values to the DAC on a one-sample based clock? Is resampling the way to go? If so, how can this be done? I'm checking the source files, specifically d_dac.c and m_pd.h, but can't make much out of it. My C skills are very limited, hence all the questions above...

i think i tried it (if i understand correctly), i started jack with rt prio and added the -jack tag to pd and it didnt work, just for test sake i tried a simple python script using pyaudio and recorded 10 min of 2 ch 192khz 24bit with no prob so im narrowing this down to pd misbehaving somehow?
