Announce: opportunity for PD/DSP teaching contract in Bath (UK)
by Martin Dupras 16 Aug '21

16 Aug '21

Hi everyone, I'm trying to find someone to cover the teaching for a PD-based "introduction to DSP" level 5 module at Bath Spa University in the coming semester. (Technically: this is level 5 (year 2) module, 20 credits, entitled "Foundations of Audio Processing." The teaching will most likely be a combination of in-person at Bath Spa and some online delivery, so would ideally suit someone already in the area. If anyone is interested, do please email me privately at m.dupras(a)bathspa.ac.uk. Many thanks. - martin

variable speed tabwrite~?
by Peter P. 16 Aug '21

16 Aug '21

Hi list, hope you are fine! I am trying to build a variable speed looper which can change its reading and writing speed by the same factor. How could this be done? It seems there is no object that allows writing to a table (or delay line) at fractional speed. There is some discussion about [tabrwrite4~] or [ipoke~] in the list archives, but it seems it never led somewhere near an implementation, unless I am missing something. Could it work by placing order-forced [tabwrite~] and [tabread~] into a resampled subpatch perhaps? It would not allow seemlessly variable speed if it worked at all... thanks for all ideas/pointers!

hi, i just installed pd on a UBUNTU notebook and i am getting error messages when opening the help-intro.pd patch. some vanilla objects (sigmund~, bonk~, choice) can't be loaded and give the following error messages: /usr/lib/puredata/extra/sigmund~/sigmund~.pd_linux: /usr/lib/puredata/extra/sigmund~/sigmund~.pd_linux: undefined symbol: __pow_finite /usr/lib/puredata/tcl/../extra/sigmund~/sigmund~.pd_linux: /usr/lib/puredata/tcl/../extra/sigmund~/sigmund~.pd_linux: undefined symbol: __pow_finite sigmund~ ... couldn't create the errors for the other 2 objects are similar with the following differences: [bonk~]: undefined symbol: __exp_finite [choice]: undefined symbol: __logf_finite these are my specs: OS: Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal PD: Pd-0.50.2 ("") compiled for Debian (0.50.2-3) on 2020/02/24 at 22:30:39 UTC can somebody help me ? thanks a lot in advance oliver

liblo server error 9904 in path (null): cannot find free port
by Alexandros 15 Aug '21

15 Aug '21

I'm trying to run a patch I've been using for a long time on a Raspberry Pi after applying some changes to it and I get the error in the subject line. After I applied the changes, before I shut down the Pi, the patch run fine. After rebooting the Pi, I keep on getting this error whenever I try to turn on the DSP. Tried adding -noloadbang but I get the same. After this error I get the "watchdog: signaling pd..." message or a crash. Tried to run this in gdb and this is the output: [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1". [Detaching after fork from child process 1131] [Detaching after fork from child process 1133] [New Thread 0x74788460 (LWP 1137)] [Thread 0x74788460 (LWP 1137) exited] [New Thread 0x73dff460 (LWP 1140)] [Thread 0x73dff460 (LWP 1140) exited] liblo server error 9904 in path (null): cannot find free port Thread 1 "pd" received signal SIGSEGV, Segmentation fault. 0x7546d48c in lo_server_add_method () from /usr/lib/arm-linux-gnueabihf/liblo.so.7 When the crash occurs gdb prints the lines below this (including it): [New Thread 0x73dff460 (LWP 1140)] The patch is quite big and needs specific hardware to run (Teensy micro-controller, and several peripherals), so I don't know if it makes sense to share it, since reproducing this error would probably require all the hardware. I know my question is rather vague, but that's all I can share right now. I'm running Pd-0.50.2 on Raspbian Buster.

Linking with mingw on linux for msw
by Orm Finnendahl 11 Aug '21

11 Aug '21

Hi, I'm getting errors when linking a custom external in mingw in a cross compile environment on linux. I'm getting a bunch of undefined reference to `__imp__post' and similar, all referencing pd's builtin functions. Adding "pd.lib" and "pd.dll" (extracted from the windows installation zip from Miller's site) to the ld command doesn't work (they don't seem to contain the required code). In this YouTube video of 2016 (https://www.youtube.com/watch?v=7hByIk-xXXw) a file called pd.a is mentioned which I can't find in the zip file. Does anyone know what to do or where I can find it? -- Orm

baton: UDP (OSC) <-> websocket
by Dan Wilcox 07 Aug '21

07 Aug '21

Howdy all, Just a quick note about a utility project which may be useful for some: baton Relay messages between UDP and a websocket with Python. Faster together. > https://github.com/zkmkarlsruhe/baton <https://github.com/zkmkarlsruhe/baton> It's basically a simple relay server which passes UDP messages to/from a websocket and is a quick way to get Pd to communicate with web browser clients using OSC via built-in objects. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

[PD-announce] Cyclone 0.5-6 is out
by Alexandre Torres Porres 06 Aug '21

06 Aug '21

Cyclone 0.5-6 needs at least Pd 0.51-3. This release we're still dealing and fixing issues with capital letter aliases. We brought this back on cyclone 0.5-0 but we're still struggling with it and it's kinda embarrassing. We seem to have finally got it right. Please test it so we can put this behind. This is for backwards compatibility as since cyclone 0.3 the idea is to just use the objects with lower case characters. The objects we're talking about are cyclone/append (*); bucket; cyclone/clip (*); decode; histo; mousestate; peak; cyclone/table (*); togedge; trough; uzi; cyclone/clip~ (*); cyclone/line~ (*); scope~; cyclone/snapshot~ (*) (*) these classes need the 'cyclone/' prefix to avoid name clashes with vanilla internals Another highlight is that [grab] now has been expanded to also grab from receive names in GUIs! Thanks to the amazing work by Matt Barber. There are other fixes and improvements, check this link for a detailed changelog => https://github.com/porres/pd-cyclone/releases/tag/cyclone_0.5-6 Get it also from deken. Cheers! _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Ableton Push 1
by Simon Iten 05 Aug '21

05 Aug '21

sorry, this is off-topic… i am looking for the full midi implementation chart of the ableton push 1 controller, since i want to inteface it with a teensy. (via usb-host function) all i can find are the specs and details for the newer push 2 controller. does somebody have the details for the older version? in particular the midi messages needed to drive the display, but all the rest would be great as well. cheers

Pd files on Linux: MIME type and (document) icons
by Max 04 Aug '21

04 Aug '21

Hi list, Linux doesn't let you define that a file extension .pd shall be opened with pd-gui. Since .pd files are of the texfile MIME type, if you set them to be opened by pd-gui, also every double click on a text document will launch pd-gui. Instead, when you want .pd files to be opened with the pd-gui executable, you first need to register a new MIME type. This is done by installing an XML file of the freedesktop standard "shared-mime-info". Albert Graef has made one for pd-l2ork/Purr Data, which you can find here: https://github.com/pd-l2ork/pd/blob/master/debuild/debian/sharedmimeinfo I've adapted that to Pure Data: https://github.com/chairaudio/pd-icon/blob/mime-install/x-puredata.xml Dan Wilcox made this repository with icons for Pure Data: https://github.com/pure-data/pd-icon I have forked that and added a method to install the mime type https://github.com/chairaudio/pd-icon/tree/mime-install The command "make mime-register" will add the MIME type. It's adapted from what I found here: https://stackoverflow.com/questions/30931/register-file-extensions-mime-typ… There are some comments on my pull request by IOhannes: https://github.com/pure-data/pd-icon/pull/6 Anyway, maybe someone more knowledgable can take over here, the goal is to include this to the Pd installation so that Pd documents on Linux have the Pd file icon and are opened by pd-gui by default. m.
