finite precision in basic math?
by Peter P. 07 Jan '19

07 Jan '19

Hi, when I send the numer 0.7 to both inlets of a [* ] object (yes, in correct order) the result is printed as 0.49 If I now subtract [- 0.49] the result is -2.98023e-08 While this is no major concern for me right now, I am still wondering which step in this simple calculation is triggering this. If I remember my CS lecture correctly it is the subtraction, right? Thanks for all hints, P

Re: [PD] .49 Hslider shortcut Shift+Control+J <---
by Dan Wilcox 07 Jan '19

07 Jan '19

It's basically another bug in Tk on macOS using the Cocoa backend. Other applications have no problem handling Shift+Command+H, however Tk's keyboard handling simply listens to key events and doesn't catch/override the NSWindow's default key bindings so the Command+H gets caught by the window and hides it. Annoying, but I didn't want to wade into fixing Tk at the time in order to achieve cross-platform consistency. > On Jan 6, 2019, at 11:40 PM, pd-list-request(a)lists.iem.at wrote: > > From: Lucas Cordiviola <lucarda27(a)hotmail.com <mailto:lucarda27@hotmail.com>> > To: Manuel Haible <lacuna_(a)gmx.net <mailto:lacuna_@gmx.net>>, "pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>" > <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] .49 Hslider shortcut Shift+Control+J <--- > Message-ID: > <BN3PR01MB19562AC771BB7085F75A9D27A6880(a)BN3PR01MB1956.prod.exchangelabs.com <mailto:BN3PR01MB19562AC771BB7085F75A9D27A6880@BN3PR01MB1956.prod.exchangelabs.com>> > > Content-Type: text/plain; charset="utf-8" > > It was changed to "J" because macOS reserves "cmd-h" for something else. > > see: https://lists.puredata.info/pipermail/pd-list/2017-07/119768.html <https://lists.puredata.info/pipermail/pd-list/2017-07/119768.html> > > :) > > Mensaje telepatico asistido por maquinas. > > On 1/6/2019 5:44 PM, Manuel Haible wrote: > > Nothing to worry, but little confusing: > in 0.49 (and 0.48) the shortcut for the horizintal slider is Shift Control J and not H, as it has been before. > > > Is this normal ¿ -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Pd 0.49 64b windows processing question (+ pd~)
by João Pais 06 Jan '19

06 Jan '19

Hello list, I just noticed that pd 0.49 comes packed with 64b. I was interested to ask what are currently the biggest advantages. I imagine that lots of added memory capacity; but for example, is it still limited to only one processor? I also notice that pd~ is in windows already for a while, I think I'll test it soon for the next version of my porting of Henke's granulator. I would like to know: is it guaranteed that parallel processes will run in different processors, or a bit of a luck game managed by the operating system? Best, Joao

Re: [PD] Pd vanilla font size
by Dan Wilcox 06 Jan '19

06 Jan '19

The GUI tries to find the font size that fits a set of predefined box sizes. The one computer might have some system settings that make this process work differently then the others and this is probably out of Pd's control. You can check a couple of things: 1. turn on log level 4 and verify the font and font weight that are being used, the print looks like "Using font: DejaVu Sans Mono normal" 2. stop Pd, edit tcl/pd-gui.tcl on two machines and uncomment the font metrics prints, then start Pd and check the log to verify the metrics are similar or vastly different: https://github.com/pure-data/pure-data/blob/master/tcl/pd-gui.tcl#L540 <https://github.com/pure-data/pure-data/blob/master/tcl/pd-gui.tcl#L540> As discussed in work on the font sizing for Pd 0.48, the way the system works there is no real *guarantee* the sizing and positioning can be pixel *perfect* between platforms. I think we're pretty close using the metrics from Pd-extended but systems and system settings change... > On Nov 28, 2018, at 9:47 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Wed, 28 Nov 2018 19:31:46 +0100 > From: João Pais <jmmmpais(a)gmail.com <mailto:jmmmpais@gmail.com>> > To: PD-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] Pd vanilla font size > Message-ID: <op.zs7ce8cr3gx0ss(a)thinkcentre.fritz.box <mailto:op.zs7ce8cr3gx0ss@thinkcentre.fritz.box>> > Content-Type: text/plain; charset=iso-8859-15; format=flowed; > delsp=yes > > Hello list, > > a small question about font size: in one of my computers the font in the > patch is bigger than in the others.

declare not working with audio files
by Maximiliano Estudies 05 Jan '19

05 Jan '19

Hi, I am trying to use [declare -path audio] to declare a subdirectory to store my audio files relative to the patch, but pd seems unable to see the files. Pd sees abstractions and text files in the subdirectory though. In the documentation says "abstractions and/or other supporting files". Are only text files supported? pd 0.49-1 and MacOS -- Maximiliano Estudies +49 176 36784771 maxiestudies.com

playing soundfont files under Vanilla / fluid~
by Robert Grah 03 Jan '19

03 Jan '19

Hey there, I like to play some soundfont files in PD. Does someone know a way to simply install the fluid~ external with deken? Or is there a different way to play soundfont instruments? I don't want to use extended. Cheers, Rob

remove wavecycles from a wavetable
by Simon Iten 01 Jan '19

01 Jan '19

hi there, i have a large amount of evolving wavetables (think ppg wave and the like) 2048 points per cycle between 64 to 256 cycles in total. those wavetables are saved to a standard wav file. i would like to “standardize” those wavetables to all contain only 64 waves, hence only keeping every n-th wavecycle and cutting out the rest. i can easily load the wav-files into an array with soundfiler and calculate the number of waves by dividing the sample number by 2048. what would be the easiest way to cut out all the unwanted waves and resave to a wav file? it is straightforward to create a wavetable-player where i can scan through the wavetable (nice!!, see attached) but i am a bit lost onwards… thanks for any pointers.
