pack_bang: warning?
by João Pais 22 Sep '16

22 Sep '16

Hello list, I got the warning "pack_bang: warning: reentry with pointers unprotected". Does someone know what does this mean? This comes up when having a loop trying to spout out all scalars with the same x value - which doesn't seem to work, as I get 2 times the same pointer, instead of 2 different pointers. Best, jmmmp

mtof~ example patches and use cases for chaos
by Robert Grah 22 Sep '16

22 Sep '16

Hallo, I just discovered mtof~, which I never used before, through this redit thread: https://www.reddit.com/r/musicprogramming/comments/2uis7s/harsh_noise_patch… In the merzdata example mtof~ is used in combination with noise~ to generate a really nice chaotic osc~ behavior over time. I was just wondering if there are other examples and use cases with a similar approach? Best, Robert

how prevent Pd from registering traces
by rolfm＠dds.nl 21 Sep '16

21 Sep '16

hello list, i would like to prevent Pd from leaving 'traces' other then what is done by my patch. i guess that if the preferences are not changed nothing will be written about that. but what about the 'recently opened patches'? suggestions are welcome rolf

Yamaha UD-BT01 Wireless Midi Adapter (Bluetooth MIDI) with Linux
by Ingo 21 Sep '16

21 Sep '16

Hi everybody, I was wondering if anybody has used the Yamaha UD-BT01 Wireless Midi Adapter (Bluetooth v4.0 MIDI) with Linux. I was wondering how you could get the MIDI data to get recognized by Pd. Does anybody have any experience or know how to use it? I would like to use it with either Debian or Raspbian (or both). Ingo

Tcl error for [knob] and [mknob]
by Christof Ressi 21 Sep '16

21 Sep '16

Hi, when I open the properties for [knob] (flatgui) or [mknob] (moonlib) in Pd 0.47.1, Tcl throws an error when building the color section and stops building the rest of the gui. I can still set the other properties and confirm with enter (since 'OK' and 'Apply' buttons are not drawn). However, after saving and reopening the patch, the knobs are a total mess, especially [mknob] can't be used at all. See attached snapshots to get an impression. Some questions: 1) Is this only happening on Windows 7? Would anyone test this on other platforms and tell if they get a similar behaviour? 2) who is the current maintainer of flatgui and moonlib? 3) would anyone have a look at the Tcl code? Unfortunately, I don't know Tcl (yet) 4) are there any other knob objects I could use in the meantime? In a perfect world there would be a knob gui included in Pd vanilla ;-) Christof

configure fails for portaudio (Windows 7)
by Christof Ressi 20 Sep '16

20 Sep '16

Hi list, I've already build several Pd externals with MinGW on Windows 7 using the pd-lib-builder, but never build Pd itself from source for this platform. 'configure' always fails for portaudio. The error message I get is this: === configuring in portaudio (/c/pd_externals/pd/portaudio) configure: running /bin/sh m4/config/configure --disable-option-checking '--prefix=/usr/local' --cache-file=/dev/null --srcdir=. /bin/sh: m4/config/configure: No such file or directory configure: error: m4/config/configure failed for portaudio There is indeed no 'configure' in m4/config. Any idea what could be the problem? I attached the config.log, in case that helps... Christof

u_thread was: [coll] bug
by Dan Wilcox 18 Sep '16

18 Sep '16

The windows thread api is pretty similar to pthread and I still don’t get why many open source projects don’t use a simple wrapper layer to abstract things. (I’m not talking about pthreads32 BTW) Here’s the old ofThread from OpenFrameworks that does exactly that: * ofThread.h <https://github.com/openframeworks/openFrameworks/blob/6e7d325ec6f0046f28149…> * ofThread.cpp <https://github.com/openframeworks/openFrameworks/blob/6e7d325ec6f0046f28149…> As long as you’re doing the threading basics like running, joining, mutex, & semaphores it’s not much code to provide access on both Windows & Unixes. Perhaps this is something we could add to the Pure Data source code itself that externals could then access. Basically just a layer with the usual callback setting mechanism and a per-thread mutex. Maybe something like a “u_thread.c" source file... -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Sep 18, 2016, at 9:51 AM, pd-list-request(a)lists.iem.at wrote: > > From: Alexandre Torres Porres <porres(a)gmail.com <mailto:porres@gmail.com>> > Subject: Re: [PD] [coll] bug > Date: September 18, 2016 at 8:06:16 AM MDT > To: Ivica Bukvic <ico(a)vt.edu <mailto:ico@vt.edu>> > Cc: Pd-list <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > > > 2016-09-18 4:43 GMT-03:00 Ivica Bukvic <ico(a)vt.edu <mailto:ico@vt.edu>>: > Instead of outright removing the feature for all platforms when it works on 2 out of 3 them, you could disable building it on Windows as it is very much useful on other platforms that support POSIX threads. > > In practice it still has it for the other platforms, cause deken still carries the previous packages. I agree though that it'd be better to just disable it for windows in the code, cause then the same package version could be updated for all platforms in deken, keeping them in sync with the same build version - and update the help file to say this was removed for the windows version because of a bug.
