Rewriting a unified phasor / metro object for reading tables
by Ed Kelly 07 Mar '14

07 Mar '14

Hi Lists(s), I'm rewriting phasor~ and unifying it with metro so that a pulse is generated from the boundaries of each ramp - so that bars of music can be read using tabread~ objects with a sample-accurate metro. I'm sure someone will say this can already be done, but it has to be dropped into the Ninja Jamm patch, so there isn't really time to rewrite the rest of the patch. I don't fully understand the way phasor~ wraps, but I have the object firing out bar numbers correctly. I'm putting clocks in for 16ths and 24ths of the beat, initiated on each wrap. I need to minimise CPU, so what I want to know is this: Does phasor~ always start from 0 and go to 1, i.e. is there always a signal value of 0 at the start of the ramp and a signal value of 1 at the end? As I write this, my common sense tells me it should be "yes" but I want to make sure. I suppose I should just try it really...

libpd iOS 64 bit crash with variadic function pointers
by Dan Wilcox 20 Feb '14

20 Feb '14

Howdy all, We've found a fun crash on 64 bit iOS related to function pointers with variadic arguments, namely @define mess macro in m_pd.h. See https://github.com/libpd/libpd/issues/56#issuecomment-33320533 I haven't delved into the pd source yet enough to propose a fix, but a quick hack which calls the function pointers directly without using the mess macro seems to work: https://github.com/libpd/libpd/issues/49#issuecomment-29535755 This is something that only crashes on the actual hardware and not in the simulator, so I hadn't seen it before since I don't have a fancy new iPhone. Any PD guru thoughts would be welcome as I (we) would like to find a way to test a change and push a patch upstream. -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

Question about multi-arch Mac OS X - is 32-Bit still around?
by Thomas Mayer 17 Feb '14

17 Feb '14

Hi, I am using the library template for PuREST JSON. This library needs libcurl for compilation, and libcurl throws errors while cross-compiling for architectures with different word sizes, e.g. compiling 32-Bit on 64-Bit. (http://ubuntuforums.org/showthread.php?t=1680426) To counter this, me.grimm has removed 32-Bit support for Mac OS X, and I have merged that with my branch. (https://github.com/megrimm/PuRestJson/commit/c9981507dfc9fb1da763c83d15a86c…) So: Is 32-Bit on Mac OS X still around? Also: The version of json-c in fink seems to be 0.10 still, while 0.11 is out for a while. Can someone please update the package? (https://s3.amazonaws.com/json-c_releases/releases/index.html) Thanks, Thomas -- "When one's home has a really excellent computer capable of reaching other computers anywhere in the Galaxy, one scarcely needs to budge."

[pure-data:bugs] #1130 SEGFAULT by changing number of JACK channels more that at start

--- ** [bugs:#1130] SEGFAULT by changing number of JACK channels more that at start** **Status:** open **Labels:** jack **Created:** Tue Jan 28, 2014 10:55 PM UTC by Anonymous **Last Updated:** Tue Jan 28, 2014 10:55 PM UTC **Owner:** nobody If I started PD with 1 channel like this: ./pd -jack -channels 1 And try to change number of JACK channels more that 1 — I'll have crash by segfault. Or can start pd with 2 channels (by default) and change to 3 channels in media and have segfault again. But if change to less than at start it works fine, without any crashes. It looks like in PD allocated jack port array at start and when we changing number of channels it doesn't reallocate memory for array. --- Sent from sourceforge.net because pd-dev(a)lists.iem.at is subscribed to http://sourceforge.net/p/pure-data/bugs/ To unsubscribe from further messages, a project admin can change settings at http://sourceforge.net/p/pure-data/admin/bugs/options.

More sophisticated clarinet model
by Dr Nicholas J Bailey 09 Jan '14

09 Jan '14

I'm working on building a microtonal instrument in Pd using a breath controller. I've got one working, using the Stanford University STK clarinet model due to Cook and Scavone, but the results, while they have been used in a performance context at conferences and so on, don't really do the performer justice. Does anybody know of something a bit more state-of-the-art that could be used to make clarinet sounding a little more convincing and being a bit more controllable? I don't mind putting a bit of effort into building a Pd wrapper for C code etc, but I really don't want to get my hands too dirty with any DSP programming right now. It would have to be something I could distribute, preferably FOSS. There's a video explaining what I'm trying to do here: https://vimeo.com/77621987 (the patch has been improved a little since then, but it still sounds pretty much the same). Alex South explains the limitations of the system we've got so far at about 6'15 and again at about 9'15. Nick/.
