moog~ in pure pd?
by Dan Wilcox 18 Feb '16

18 Feb '16

Forgive me, I'm no low level dsp guru. I'm curious. How would one make the ggee [moog~] external in pure pd? [vcf~] sounds close, but of course, it's a band pass so it's not a real replacement. I messed with rjlib [e_beequad= + [u_lowpassq] which sounds pretty good, but there no signal rate frequency control, which I'd need for those nice filter sweeps. I'm trying to lessen my reliance on externals (where possible) and moog~ is one of those without an obvious replacement. -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

hi List all this talk about convolution made me look for this great apparatus once again, but it wont compile ... ld: partconv~.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC partconv~.o: error adding symbols: Bad value Makefile:21: recipe for target 'partconv~.pd_linux' failed make: *** [partconv~.pd_linux] Error 1 can anyone help me understand what " -fPIC" flag means and how do I recompile it? best regs ~/.jc

Autocorrelation (and similar) functions in PureData? Could they be leveraged from e.g. Scipy?
by Matti Viljamaa 31 Jan '16

31 Jan '16

Hello, I found few confusing posts regarding autocorrelation in PureData, but they didn’t clarity, whether it’s in Pd or whether there’s some reasonable way to get it to Pd. So is it there or is there a reasonable way to get it there? I was thinking of if perhaps some python external would allow using signal processing functions (incl. autocorrelation) from Scipy? Anyone know if that’s feasible? Best regards, Matti Viljamaa

installing iemlib on Mac OS X
by Raphaël Ilias 31 Jan '16

31 Jan '16

Hello dear list, I have to work abroad for a few months with a Macbook Pro, and I am not familiar with OS X. I'm trying (unsucessfully) to install a few libraries with Pd 0.46-7 (which I could install and get to work easily), especially iemlib, zexy and ggee, but following their various compilation instructions (essentially executing a few terminal commands, ./make etc) I could not make any of them work. Does someone have any experience with this ? I am running Mac OS X 10.10.5 Yosemite. Cheers, Raphaël

Re: [PD] fftease 3.0 compatibility with Linux. Was Re: fftease compatibility with Pd-0.46-7
by Samuel Burt 29 Jan '16

Ivica, I'm trying it out now. I had previously tried installing pd-fftease 2.5.2 through deken. I grabbed the lyon/ folder out of Pd-l2ork and dropped it into ~/pd-externals. Pd was using the deken version (2.5.2), instead. So, I removed fftease from /usr/local/lib/pd-externals and copied the lyon/ folder there. I then created [pvoc~], but when I turn on audio with a [pvoc~] object, Pd crashes with a segmentation fault. [granola~] (the granular pitch-shifter) works so I am assuming some of the other fftease objects work, but [pvoc~] gave me a hard crash every time. I'll keep hacking away at it. If anyone else discovers a solution, let me know. I could also reformat the patch to use the 2.5.2 [pvoc~] although then I can't program the patch on my Mac and then transfer it straight. I'd have to heavily modify it every time. Thanks for the recommendation to use pd-l2ork's libraries.

Re: [PD] Pd-list Digest, Vol 130, Issue 88

I messaged Eric Lyon off-list, just in case he wasn't on list. That's when I also discovered he was hosting fftease on git. We should probably update some documentation at puredata.info to point users there. Big thanks to Eric for taking time at the start of the semester to answer my email. I will now summarize the problem I'm having and the steps I've taken to unsuccessfully get fftease working. I'm on Mac OS 10.9.5. I updated Pd vanilla to 0.46.7 32-bit. When I load Pd, you will see that zexy and GEM load correctly, but other libraries appear to not load, although I can call their externals in Pd. Here's my log window: ============== deken-plugin.tcl (Pd externals search) in /Users/sburt/Library/Pd/deken-plugin loaded. Platform detected: Darwin-x86_64-32bit 'deken-plugin.tcl' already loaded, ignoring: '/Users/sburt/Library/Pd/deken-plugin/deken-plugin.tcl' cyclone: can't load library ♡♡♡ ♡ the zexy external 2.2.6svn ♡ (c) 1999-2012 IOhannes m zmölnig ♡ forum::für::umläute ♡ iem @ kug ♡ compiled: May 29 2015 ♡ send me a 'help' message ♡♡♡ warning: class 'abs~' overwritten; old one renamed 'abs~_aliased' matchbox: OSC-pattern matching code (c) Matt Wright, CNMAT warning: class 'wrap' overwritten; old one renamed 'wrap_aliased' GEM: Graphics Environment for Multimedia GEM: ver: 0.93.3 GEM: compiled: Nov 10 2011 GEM: maintained by IOhannes m zmoelnig GEM: Authors : Mark Danks (original version) GEM: Chris Clepper GEM: Cyrille Henry GEM: IOhannes m zmoelnig GEM: with help by Guenter Geiger, Daniel Heckenberg, James Tittle, Hans-Christoph Steiner, et al.

There's not a lot of information on this subject there. While I can access externals from these libraries, cyclone, iemlib, hcs, etc., I cannot get the fftease objects to instantiate. I next deleted my Pd preference files from my user Library and recreated my search paths and Libraries-on-load. Still no change. Log window: ============== dentist~ 2048 8 ... couldn't create dentist~ 2048 8 ... couldn't create fftease/dentist~ 2048 8 ... couldn't create ============== Eric suggested downloading and compiling fftease. So I downloaded the source and followed the instructions to "make" and then perl script that moves all the .pd_darwin files into a folder. I put the external folder and help folder in ~/Library/Pd/, but they still didn't work. The "make" command seemed to work correctly although it did throw "sed: fftease-meta.pd: No such file or directory" a few times when it started and it threw "bthresher~.c:139:48: warning: unused parameter 'msg' [-Wunused-parameter]" for every object. Now, that I've recompiled and reinstalled the externals, [pvoc~] won't load as I was describing before. I'm glad fftease is alive and well. The externals are amazing! I just wish I could figure out what is going wrong on my end.

About PdDroidParty and OSC...
by Mario Mey 29 Jan '16

29 Jan '16

Hi, there. Some days ago, I started to migrate from TouchOSC to MobMuPlat. But, finally, I discovered that MMP does not receive well OSC messages in my tablet (Android 4.0.3)... and it works OK in another devices. So... it's difficult to fix a Android version bug... I reported it, and I will wait for Daniel response. For the moment... I wanted to give a try to PdDroidParty. I installed it and, before learning how to make my Patch, I made a research. And I found this: http://comments.gmane.org/gmane.comp.multimedia.puredata.general/83185 It is from 2012... I wanted to know if actual PdDroidParty version can receive and show OSC messages... I just want to send OSC to the computer (buttons, toggles, sliders, touch-XY, etc) and receive OSC in tablet (strings, toggle and color settings, etc). No sound processing in the tablet. And sorry about choosing MMP before PDP...! It gave me the impression of being more robust... (isn't it?) Thanks in advance!

MobMuPlat receiving OSC messages.
by Mario Mey 29 Jan '16

29 Jan '16

I'm working with MobMuPlat and I'm having problems with receiving messages through OSC... but the problem is not in MobMuPlat, but in my tablet Android version (4.0.3). If I send with Pd-Extended 0.44 or Pd-Vanilla 0.46, the messages arrives in a weird mode. Sometimes, they arrive good... sometimes, the first element in the list is lost, sometimes it concatenates the first word of the last message with the actual message... it converts 0 or 1 to a float (e.g. "2.7908e+29")... etc. My question: while I still have this tablet (and don't buy another one) and this problem can't be resolved (because it is not a MobMuPlat bug)... Is there any way to send a message previously packed and to be unpacked in MMP patch? I don't know... to put everything in a single packed message... (a blob?) and then, the tablet MMP patch converts to the real message. Maybe this could be a workaround... Thanks!

Re: [PD] libpd crashes with vlines~ in (libpd) clock_unset (?)

Hi Miller and Pascal, I’m getting the same crash using the latest libpd and pd 0.46-7 (the printout for clock_unset() is exactly as it should be). Pascal, have you managed to find out what causes the crash?
