Bizzare problem with freeverb~
by Juan I. Rivero 12 Aug '09

> Freeverb~ is not really "passed", it's just that pd relies on the gui startup latency before connecting to any soundcards, etc. In -nogui mode, there's no gui setup and it tries to grab the soundcard too quickly and failes, at least that's my understanding of the problem. I noticed this using -nogui mode and -rt, -alsa in Linux. > > There is a bug report for this, add your info there as there is no mention of this happening in OSX ... > > To solve, I added a delay before starting the dsp as mentioned by IOhannes and the bug report (I use 100ms): > > [loadbang] > | > [; pd dsp 1< > > in my main patch becomes > > [loadbang] > | > [del 100] > | > [; pd dsp 1< > > I rely on -nogui, so this was a major problem for me about 2 months ago when I switched form using pd through Jack to direct alsa.

Did not work for me. I've tried different delay times and same thing happens: freeverb~ does not apply any effect on the audio when I run pd -nogui. This looks like a bigger problem to me, maybe related to running Pd from the command line on Mac OS X (see http://www.mail-archive.com/pd-list@iem.at/msg27281.html). I believe this since I also tried running the patch from the command line WITHOUT the -nogui flag, and the delayed loadbang doesn't start the dsp at all!!! So maybe it's a bug to be fixed. Any ideas?

Hi William, I would say that the meaning is clear for those of us who have patching habits in Pd. However, my main point is that the relevance is not clear, especially for people reading about Pd for the first time. I've heard and read at least five comments in the past year from people who have taken a cursory glance at Pd and found it necessary to mention they dislike the idea that "execution order is determined by the order in which connections are made." I know these people are aware of the [trigger] object, so my only explanation is that they think the order in which connections are made is useful as a common patching practice. Additionally, in section 2.3.3 it is stated that the second patch example (which has two connections coming from the number atom) is incorrect because the author made the leftmost connection first. Equally important, and unstated, is that such an idiom is _never_ relied upon in Pd. If you're reading the manual for the first time, how would you know which of the following is true: a) [trigger] is used to disambiguate execution order for the beginner, and for situations in which execution order gets complex. But for simple idioms, one can use connection order as a shortcut. b) The patch example is not idiomatic Pd, but the one that uses [trigger] is. [trigger] should _always_ be used for visual clarity whenever execution order matters. Here's my first attempt to clarify the relevance of the sentence I quoted in the first email (Section 2.3.2): Whether "B" or "C" is done first depends on the order in which you made the connections. This means you cannot determine the execution order simply by looking at the two connections coming from "A." In practice, Pd patches never rely upon the order in which connections were made to specify execution order. In situations where execution order must be specified, the [trigger] object is used (see section 2.3.3 below). And in section 2.3.3: Change: Here, I connected the left inlet before connecting the right hand one (although this is not evident in the appearance of the patch.) To: If I had connected the left inlet before connecting the right hand one, the "+" would add the new input (at left) to the previous input (at right). If I had connected the right inlet first, the patch would produce the correct output, but the problem remains the same: the execution order is not evident in the appearance of the patch. -Jonathan

how to deploy PD in a server?
by Adityo Pratomo 12 Aug '09

12 Aug '09

Hi there folks, Does anybody now whether can PD be deployed in a server and then anybody can login into that server and run PD without have to install PD on the client side? What are the requirements for this? I understand that there's NetPD, i haven't read much about it, buat isi this sufficient? Because i am thinking about making music using PD and then run the abstraction and patches on a server, so anyone who want to hear it can just login to the server. Is it possible? Thank you very much -- mataharipertama.wordpress.com myspace.com/downstairsbohemian

how to find [r $-0_anyname]
by Ingo Scherzinger 12 Aug '09

12 Aug '09

I am looking for a search function to find [send] and [receive] objects within abstractions that use "$0" at the beginning of the name. Ctr+f doesn't find anything even if I replace $0 with the number (for example 1003) that it actually represents. Any ideas? Ingo

Bizzare problem with freeverb~
by David F. Place 12 Aug '09

12 Aug '09

Hi: I would like to do some batch processing into ".wav" files. This should be easily accomplished by running pd with -noaudio and -nogui. It almost works. I run my signal through [freeverb~] just before output. If I run the patch with -nogui, freeverb~ is bypassed and the sound is dry. In every other way, it works properly. Why this difference in output just because of -nogui? I attach a demo patch. To reproduce: To hear the output with reverb: 1. pd -noloadbang freeBug.pd 2. click on the bang labeled "Click!" 3. wait about 15 secs, pd will quit 4. aplay /tmp/foo.wav With reverb mysteriously bypassed: 1. pd -nogui freeBug.pd 2. wait about 15 secs, pd will quit 3. play /tmp/foo.wav uname -a Linux Congo 2.6.25.14-108.fc9.x86_64 #1 SMP Mon Aug 4 13:46:35 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux pd -version Pd version 0.41-4 compiled 18:31:52 Aug 14 2008 freeverb~ 1.2

Puredata for Nintendo DS

It would be awesome don't you think ?!! Since Pd already is, imagine a little one you can carry on your pocket. I have lots of sound-music applications on it (elektroplankton, korg ds-10, nitrotracker, lots of home brew).. they are great, but we all know they can't do what pd can. Imagine a little vanilla, you just mess with the objects on the touchscreen, man .. who is interested?

Now that works, fun stuff! A little rough around the edges, but works nicely. One suggestion: 'toolkit' is a very general name, it would be nice to have a more descriptive, unique name. editk? fricklrtk? fritk? .hc On Aug 11, 2009, at 5:20 PM, Georg Werner wrote: > now the oops is on me ;) > i updated it again - i hope now everything is there ... > g. > > Hans-Christoph Steiner schrieb: >> oops, just saw this.
