add inlets to [ctlin]
by mario buoninfante 31 Mar '18

31 Mar '18

Hi Roman, you're absolutely right, in fact that's the way I'm doing. but I suppose that having the possibility to directly set the object would allow to have better performances. Imagine a situation where you have 10 [ctlin] objects in a patch and then you implement the kind of filter we're talking about (a couple of [spigot] and [==] in my case). in this scenario, every time a CC message is sent to the patch, all these objects are exercised ([ctlin] + 2 [spigot] + 2 [==], all of them * 10). this wouldn't happen if [ctlin] had 2 inlets to set the arguments on the fly. all the processes would happen under the hood, within the 10 [ctlin] objects, without involving other objects. cheers, Mario

add inlets to [ctlin]

Hi all, is there any particular reason why on [ctlin] there are no inlets that allow to change MIDI channel and control number on the fly? do you guys think it would be useful to have it? cheers, Mario

Re: [PD] handling path and filenames with spaces in vanilla 0.48
by Dan Wilcox 30 Mar '18

30 Mar '18

As you say, the space in the path makes text output the path as a list of symbols. Some people would say to not use spaces in file paths, but I've been using them successfully for many years. You basically just need to make sure to join the list into a single symbol before trying to use it. Same with trying to save it. I've used [symbol2list] previously and now use a vanilla equivalent which uses [list tosymbol] / [list fromsymbol] internally. It's called [u_list2symbol] and you can find it in https://github.com/danomatika/rc-patches <https://github.com/danomatika/rc-patches>. There are similar implementations people have shared with the list in the archives as well. I also have a playlist abstraction if that's what you're building [c_playlist] as well as some file path helpers. > On Mar 30, 2018, at 2:42 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Fri, 30 Mar 2018 11:53:55 +0100 > From: Mikael at UL <mikael.fernstrom(a)ul.ie <mailto:mikael.fernstrom@ul.ie>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] handling path and filenames with spaces in vanilla 0.48 > Message-ID: <DB9641BC-EC4B-4882-9586-E981E9FBB4C3(a)ul.ie <mailto:DB9641BC-EC4B-4882-9586-E981E9FBB4C3@ul.ie>> > Content-Type: text/plain; charset="utf-8" > > I’m currently reworking some of my older patches and moving from Extended to Vanilla 0.48.0 > > I have a text object defined: > [text define -k filelist] > that contains 16 file names (i.e. full path and file name). > File names are set by [openpanel] etc. > > The file names are also passed on to [soundfiler] with the message: > > [read -resize -raw 128 2 2 b $1 table1 table2( > > where $1 is the message from [openpanel] (path+filename) > > I store filelist by sending [write myfilelist.txt( to the [text define -k filelist]. > > When I try to read back the list by sending > [read myfilelist.txt( to the [text define -k filelist], the text (path + filename) cannot be passed on via a message as a $1 argument to [soundfiler], as the text now appears to be parsed and breaks at the first space in the path+file name. > > Any suggestions? > > /Mikael -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

handling path and filenames with spaces in vanilla 0.48
by Mikael at UL 30 Mar '18

30 Mar '18

I’m currently reworking some of my older patches and moving from Extended to Vanilla 0.48.0 I have a text object defined: [text define -k filelist] that contains 16 file names (i.e. full path and file name). File names are set by [openpanel] etc. The file names are also passed on to [soundfiler] with the message: [read -resize -raw 128 2 2 b $1 table1 table2( where $1 is the message from [openpanel] (path+filename) I store filelist by sending [write myfilelist.txt( to the [text define -k filelist]. When I try to read back the list by sending [read myfilelist.txt( to the [text define -k filelist], the text (path + filename) cannot be passed on via a message as a $1 argument to [soundfiler], as the text now appears to be parsed and breaks at the first space in the path+file name. Any suggestions? /Mikael --------------------------------------------------- Dr. Mikael Fernström Interaction Design Centre Department of Computer Science and Information Systems University of Limerick Limerick V94 T9PX IRELAND Phone: +353 (0)61 20 26 06 (office) Mobile: +353 (0)86 81 88 079 Email: mikael.fernstrom(a)ul.ie Web: mikaelfernstrom.ie

Hi list, ofelia v1.0.6 is now available. This version includes [pdgui] abstractions which emulate pd's built-in GUI. Please try out "ofelia/examples/gui/pdguiExample.pd". Screenshot: https://github.com/cuinjune/ofxOfelia/blob/master/doc/pdgui_screenshot.png More GUI abstractions will be added in the close future. You can also customize the look/behavior of the GUI if you know the basics of ofelia. Changes: * [ofCreateFbo] auto MSAA scaling is disabled * fixed bug for mesh editor and getter objects * [ofReceive], [ofValue] can change name dynamically * float inlet is removed from [ofGetCanvasName], [ofGetDollarZero], [ofGetDollarArgs], [ofGetPatchDirectory] as it's problematic when used in cloned abstraction * [ofGetPos], [ofGetScale] are renamed to [ofGetWindowPos], [ofGetWindowScale] * [ofGetTranslate], [ofGetRotate], [ofGetScale] are added * [pdgui] abstractions are added to the "examples/gui" directory * [ofMap] has 5th argument which enables/disables clamping * [ofGetElapsedTime], [ofGetLastFrameTime] returns time in seconds * [ofGetElapsedTimeMillis], [ofGetLastFrameTimeMillis] are added Upcoming features: * More GUI abstractions * GLSL shader loader * Video player and grabber More info about ofelia: https://github.com/cuinjune/ofxOfelia Cheers _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Pd does not follow switch of sound output (on Windows 10)
by rolfm＠dds.nl 29 Mar '18

29 Mar '18

on Windows 10, Pd 48.1. when i switch (on forehand) the sound output to the headphone connection or a USB-soundcard, Pd stays with the on-board speakers. only after changing in Pd the audiosetting to ASIO and back, Pd starts using the headphone or USB-card. rolf

Notes about cross-platform installation
by abel.jerome＠free.fr 28 Mar '18

# X-PLATFORM INSTALLATION NOTES Hi, For the new version of [malinette](http://framagit.org/malinette), I would like to find the easiest way to install pd with 21 external libraries and our project. Here, "Installation" has not the same meaning than "INSTALL.txt" file, which is about compilation. We should have a "one-click" installation : download, unzip and launch. ## GENERAL NOTES - In "INSTALL.txt", I don't understand this command :"./configure --enable-universal". Is it possible to compile Pure Data for Windows, Mac and Linux from a Linux computer ? - When add "-lib" ? Here's the answer : https://lists.puredata.info/pipermail/pd-list/2017-12/121024.html - Big enhancement of Deken for us : [Download a list of packages](https://github.com/pure-data/deken/issues/94) - May be an up-to-date text on puredata.info would be nice. ## WINDOWS 7,8,10 - Download Pd as zip archive from [Miller Puckette website](http://msp.ucsd.edu/software.html) : Microsoft Windows 32 bit version (XP or later) (zip archive) - For Gem, copy "msvcr71.dll" to the "pd/bin" folder of the zip archive or to "C:\Windows\System Folder". [Source](https://lists.puredata.info/pipermail/pd-list/2017-04/118639.html) - Force [cyclone/gate] instead of [iemlib1/gate] : https://lists.puredata.info/pipermail/pd-list/2017-12/121017.html **Some issues** : - using [coll] with Cyclonev0.3.beta2 stopped Pd : "PD.exe RunTime Error" - using [pduino] on Windows 10 with a Arduino Leonardo+Firmata firmware was Windows 10 : Leonardo/Firmata + pduino/arduino > solution : Uno or Midi - using [pix_video] on integrated camera / Windows 10. May be this version of Gem on : https://github.com/avilleret/Gem/releases ## MAC OS X - With Gem, you should download the 32 bits version from [Miller Puckette website](http://msp.ucsd.edu/software.html) : 32-bit ("i386") Macintosh version for OSX 10.6 or later. Some infos on the [pd-list](https://lists.puredata.info/pipermail/pd-list/2017-09/120361.html) **Issue** : - using [Gem/pix_video] on integrated camera. May be this [fork of Gem](https://github.com/avilleret/Gem/releases) would solve the issue and webcam usb logitech **Questions** : - I don't remember if we need XQUARTZ now ? - When I download the app from Miller Puckette on my Linux laptop and I compress it to share the project, the app don't launch on Mac OS X. I use a Mac to compress it... Is it something I miss ? ## LINUX - "apt-get install puredata" don't show the must up-to-date version and I would like to share my puredata to other Linux. I don't find any binaries, so I need to compile it from the github sources on my computer and compress necessary files. Do you think it is the best way ? - I see .deb files here for debian distributions : http://cdn-fastly.deb.debian.org/debian/pool/main/p/puredata/puredata_0.48.…. - I would like to share Gem too. For Gem, I don't understand if the "apt-get install" is better than "deken" way. The advantage of deken is that I've just to copy files from the "Gem" folder and share it inside my project - For Gem, do I need to have libftgl2 (apt-get install libftgl2) ? This error appears sometimes : Gem.pd_linux: libftgl.so.2: cannot open shared object file: No such file or directory. Solved by "apt-get install", but if I prefer the deken way. Thanks for any improvements, suggestions. Best. Jérôme http://jeromeabel.net

Best practices for pitch shifting a sample?
by afleck＠inventati.org 26 Mar '18

26 Mar '18

Hello, I started thinking about this problem because I was doing some frequency modulation, but when I tried to change the carrier frequency directly with notein and mtof~ there were sometimes unpredictable results (which can sometimes, but not always, be remedied by maintaining a fixed ratio between the carrier and modulation frequencies). DAWs like Ableton allow you to select a sample (such as a kick drum) and then play it at a bunch of different pitches (i.e. with a midi keyboard). How do they accomplish this? Is it with variable delay? I've been looking at the section on pitch shifting in Puckette's book (http://msp.ucsd.edu/techniques/latest/book-html/node115.html#sect7.pitchshi…), but I thought I would ask if there's an easier way before I take the plunge. I've tried granular synthesis but it doesn't preserve the timbre very well. To be clear, I don't just want suggestions of externals, I actually want to program it myself (in pd-vanilla) Best, Andrea
