readsf~ questions
by Simon Iten 11 Sep '21

11 Sep '21

hi there, I am finding conflicting (unclear) info on readsf~ behaviour. I want to loop a long 8 channel wave file. here are my questions: -once i open the file with a message and after a delay start playback and it has finished (rightmost outlet bangs), can i restart playback without delay ([t b b] to open and 1 for start) or do I have to set a delay again? (will the buffer somehow be ready faster) -if above is not possible, what happens if the open message is sent 15 minutes before the 1 message to start playback, are there any downsides? the fact that I can set a buffer size seems to suggest that that buffer will simply be filled and after that it waits for the playback to start. (I would use two readsf~ in tandem, one will start the other when it has finished) cheers

executing commands from pd via pdreceive
by Peter P. 11 Sep '21

11 Sep '21

Hi list, I am trying to execute shell commands from withing pd using the FUDI protocoll and the command line programs pdsend and pdreceive. I want to trigger the espeak command from within pd. On Debian it already works using pdreceive 8888 udp | espeak and sending words to speak as a message to [netsend -u] in a Pd patch. Now espeak has nice flags, such as the -p 50 flag for pitch. I would like to send this from pd as well and am now sending the command itself to pdreceive as pdreceive 8888 udp | sh and a Pd message containing send espeak -p 20 "blah blah blah" which works as well. Is there a way I can let pd know that the command has finished executing? For example by sending something back like pdreceive 8888 udp | sh - ; echo "done" | pdsend 8889 localhost udp which sadly does not work? I would also like to spawn multiple espeak commands in parallel from one [netsend] using this approach but can't seem to make it work. Again using the command pdreceive 8888 udp | sh and including an ampersand at the end of the Pd message like send espeak -p 20 "blah blah blah" & throws a sh: 1: Syntax error: ";" unexpected error on the shell terminal with pdreceive exiting. Does anyone have an idea what I can try here (except for writing a wrapper script)? Thank you for all ideas! P

New color format in patch source
by Roman Haefeli 10 Sep '21

10 Sep '21

Hey all I'm using current git master and found that the way color information of iemguis is stored in the patch file has changed. The number representing 6-bit-per-channel rgb values got replaced by a hexadecimal encoding like '#dfdfdf'. That is a huge advantage, but how far back are such patches compatible? What is the oldest version of Pd that loads patches using hex color codes correctly? Roman

Editing GOP abstractions
by Roman Haefeli 10 Sep '21

10 Sep '21

Hi When using GOP abstractions with 'Hide object name and arguments' checked, I seem to not be able to change the arguments after creation. When rewriting the whole argument list in a new object is too tedious, I sometimes revert to editing the patch file with a text editor. Is there a way to edit arguments after creation? If not, shouldn't there be a way to support that? Roman

One new object in Pd, one giant leap for Pd programmers! What a great addition. Many thanks! Roman

Re: [PD] playing random media (bit OT)
by Dan Wilcox 09 Sep '21

If I would approach something like this with all the media on disk and only needs to be accessed locally, I would write a simple OSC database server with something like Python. Basically, have a script that crawls through all the folders and fills an SQLlite dB which the server then reads from and have some basic queries via OSC. Pd could then say "I want an image" and the server would respond with an OSC message containing the fullpath as a string and perhaps any additional metadata which might be useful. The type and amount of metadata depends on how much pre-processing and/or manual tagging you want to do. That would be a relatively quick & dirty solution. I'm sure there are more robust and generalized media servers out there, but for some things making a streamlined & focused solution is useful. > On Sep 9, 2021, at 12:00 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Thu, 09 Sep 2021 10:00:24 +0200 > From: rolfm(a)dds.nl <mailto:rolfm@dds.nl> > To: Pd list <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] playing random media (bit OT) > Message-ID: <13343ae5530cdee19236aec18082b54e(a)dds.nl <mailto:13343ae5530cdee19236aec18082b54e@dds.nl>> > Content-Type: text/plain; charset="us-ascii" > > hi, > > in memory of a great friend i lost > > i'm looking for a way to play at random from his huge archive > > of mixed media (movies, pictures, sound). > > preferably with Puredata. > > to build it from scratch is at this moment too big for me. > > it would be very much appreciated when somebody can point me > > to something that goes in the direction of this goal. > > rolf -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

playing random media (bit OT)

hi, in memory of a great friend i lost i'm looking for a way to play at random from his huge archive of mixed media (movies, pictures, sound). preferably with Puredata. to build it from scratch is at this moment too big for me. it would be very much appreciated when somebody can point me to something that goes in the direction of this goal. rolf

Nestable Dictionaries in Pd
by Pierre Alexandre Tremblay 08 Sep '21

08 Sep '21

Dear all I am trying to find the most Pd-vanilla-way to interface with our Dataset object in the FluCoMa project. In Max and SuperCollider we use Dictionaries, which are nestable and queryable in powerful programmatic ways, working essentially like interfaces to JSON-like data structures. I’ve looked at [struct] but the [set] object does not allow to do symbols and (list of) floats, and [appends] seem to have the same limitations. In all cases, I’m not certain it is the best approach in any cases to create such a list in Pd... I wonder how people do it and if I am missing an obvious workflow, especially with nested structures. Any pointer (pun intended) welcome p

Howdy Mitch, Yeah, I've noticed it for some months but haven't looked into it. It's most likely the GUI not getting the patch passed to it for the system, whether this is a fault in Tcl/Tk or not.

Opening Pd document on Mac
by mitchell turner 03 Sep '21

Hi all. First, thanks to all of you who work on Pd development. Though I do not, I want you to know how important this application is to me and my work. However, I do have one issue. After updating to version 0.51-4, I find that when I double click on a pd document (e.g., my_file.pd), the program opens the console but the patcher window itself does not. I need to double click the “my_file.pd” document a second time for it to launch. Anyone know what might be the issue? I’m using: MacBook Pro (13 inch, M1, 2020), MacOS 11.5.1, Pd 0.51-4 I looked through the last few months of the list archive but did not see this issue addressed. Apologies if I missed a thread that covers this issue. Thanks for any help, Mitch
