Re: [PD-dev] patch for mrpeach/tcpserver.c
by Ivica Ico Bukvic 08 Jun '10

08 Jun '10

Speaking of tcpserver.c isn't the tcpserver_notify() function making an unsafe outlet_float() call when it is being triggered by an external event (disconnection) which can happen out-of-order and thus potentially causing crashes? Shouldn't this be wrapped also in a clock_delay()? Best wishes, Ico

external weirdness only on windows
by Lorenzo 15 May '10

15 May '10

Ok so, whilst keeping in mind IOhannes advice about getting into C externals, I had a go at writing my simple 'maths' external in C. Everything seems to work fine and I created a test patch... but *only on windows* if I re-open the saved test patch (which has 3 numberboxes connected to 3 inlets, and a numberbox connected to the outlet) the object box (I mean the gray "thing") is disappeared and only a text like a comment is there (I can even drag it around). If I recreate the object and attach the numberboxes again everything is fine. If the object is without anything attached everything is fine. In linux everything is fine... Could it have something to do with the DLL I'm linking or is this some hidden mistake in the external code? Clues appreciated. Lorenzo. PS: I'm using 0.42-5-extended.

iPd
by Christopher Niven 15 May '10

15 May '10

Hi Everyone! First time poster here – I would like to introduce you all to my project, iPd. http://www.music.mcgill.ca/~chris/ipd/ http://code.google.com/p/ipd/ Youtube channel: http://www.youtube.com/iPdProject iPd is an open source port of Pd for the iPhone OS specifically designed for iPhone developers to utilize within their projects. The goal is to be able to utilize the flexibility of Pd within iPhone applications as a useful and interesting audio/control flow engine. This project is part of my undergraduate degree requirements for Music Technology at McGill University, and my supervisor suggested that now would be the time to introduce it to you all. The project is still in its very early stages (there is a lot missing!), but here's what I've been able to do so far: - loading and running Pd patches - sending messages from the iPhone application to interact with Pd - receiving output from Pd to trigger events in the iPhone application Again, there are a lot of features that are missing or don't work (there's no audio – yet), and my code is extremely messy at best. However, if you're interested, feel free to download the example project in the google code page and try it out for yourself! Thanks for your time, Chris Niven

[ pure-data-Bugs-1821847 ] writesf~ makes junk soundfiles if started with DSP off

Category: puredata >Group: v0.43 Status: Open Resolution: None Priority: 9 Private: No Submitted By: Hans-Christoph Steiner (eighthave) Assigned to: Miller Puckette (millerpuckette) >Summary: writesf~ makes junk soundfiles if started with DSP off Initial Comment: I have been wrestling with tracking down why my Swirler program won't record audio. Most of the time, when I try to use [writesf~] to record, it does not work at all. It creates the file when I send the open message, and I get a file of 44 bytes, then when I click start, and then stop, the file does not change. Occasionally, it will record about 1-2 seconds of material, no matter when I hit stop. Very occasionally, it will work fine on its own. I tried also with the writesf~ help patch, as well as others. It seems that my program Swirler stops writesf~ from working anywhere. writesf~ works fine until I run Swirler and click the "start" button, which turns on the DSP and starts the audio processing part. This is currently happening on Mac Book Pro/Intel running 10.4.10 with Pd-0.40-2, Pd-0.39.3-extended, and Pd-0.40.3-extended-20071026. This happened previously with Pd-0.39.3-extended-rc? on a PowerMac G5/PowerPC running Mac OS X 10.4.8(ish). I compiled Pd with DEBUG_SOUNDFILE on to see if I could see what's happening. You can plainly see it's not writing data to the file. I found a strange workaround sequence that makes it record, but then the write cycle is strange, it goes in bursts every few seconds rather than a chunk every second. I attached the swirler program and some transcripts from teh DEBUG_SOUNDFILE stuff. ---------------------------------------------------------------------- >Comment By: Hans-Christoph Steiner (eighthave) Date: 2010-03-30 17:24 Message: it seems to me that the issue is triggered by sending [open( and [start( to [writesf~] while DSP is off. ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2010-03-29 20:35 Message: here's another patch from Joshua Clayton that also triggers this bug ---------------------------------------------------------------------- Comment By: ClaudiusMaximus (claudiusmaximus) Date: 2008-04-07 06:36 Message: Logged In: YES user_id=769033 Originator: NO Here's a patch that creates rubbish wav files here in pd-0.40-3 vanilla: #N canvas 0 0 450 300 10; #X obj 146 203 writesf~; #X obj 66 40 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X msg 146 176 open bug.wav \, start; #X obj 66 67 t b b; #X msg 184 125 \; pd dsp 0; #X obj 66 115 delay 1000; #X obj 66 141 t b b; #X msg 66 187 \; pd dsp 1; #X msg 181 78 stop; #X connect 1 0 3 0; #X connect 2 0 0 0; #X connect 3 0 5 0; #X connect 3 1 4 0; #X connect 5 0 6 0; #X connect 6 0 7 0; #X connect 6 1 2 0; #X connect 8 0 0 0; Before stop is hit, the bug.wav is 44 bytes, when stop is hit the size increases to a small number (up to a few 100kB). ---------------------------------------------------------------------- Comment By: IOhannes m zmlnig (zmoelnig) Date: 2008-04-07 06:12 Message: Logged In: YES user_id=564396 Originator: NO could you provide a patch that triggers the problem without external dependencies? ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-10-28 19:41 Message: Logged In: YES user_id=27104 Originator: YES File Added: writesf~-bug.pd ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-10-28 19:40 Message: Logged In: YES user_id=27104 Originator: YES File Added: writesf~-bug_after_swirlrer-1.txt ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-10-28 19:39 Message: Logged In: YES user_id=27104 Originator: YES File Added: swirler-2007-10-28.tar.bz2 ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-10-28 19:37 Message: Logged In: YES user_id=27104 Originator: YES I forgot to include the strange workaround sequence: 1) turn on DSP 2) turn on record switch (start recording) 3) turn off record switch (stop recording) 4) turn on record switch (start recording again) 5) turn on START switch in swirler 6) make recording 7) turn off record switch (stop recording) 8) turn off START switch in swirler The turn off order seems important too. ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-10-28 19:13 Message: Logged In: YES user_id=27104 Originator: YES File Added: writesf~-bug_working.txt ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1821847&group_…
