Re: [PD] shmem and bigger buffer size

I don't know why it fail on mac. You can try to split in smaller table, like you suggested. But you should also test it on linux first since it's your main target. c Le 30/01/2020 à 19:55, iftah gabbai a écrit : > im building on mac os 10.12 and intending to run on linux(arm), i haven’t tested on linux, the problems im having are on mac, > > thanks! > > On Thu 30.

svn or git on github or sourceforge?
by Peter P. 10 Feb '20

10 Feb '20

Hi list, I am wondering if Pd and externals development happens via subversion or git? The page https://github.com/pure-data/pure-data says it is a "tracking puredata SourceForge git repository ". So am I correct to assume that development happens via git on sourceforge servers? Thanks! P

Seeking feedback on batch mode manager
by Charles Z Henry 09 Feb '20

09 Feb '20

Hi list, I've reached a stopping point on a batch mode manager with communication. https://github.com/czhenry/czbs Using ggee/shell, I start "-batch" processes or for editing "-noaudio". Those processes can read from shmemID's that the toplevel process may have set values. They can also write back values to shmemID's that the toplevel process polls. My objective is to be able to run a realtime thread and offload some processing periodically to another thread. I had experimented with using "-batch" as flag with pd~, but my conversations with Christof showed me I didn't understand it at all. I was aware of shell, but I'm leery of having much disk access. A good solution should cause as little risk to the realtime process as possible. I was looking for a way to keep things around in memory and sending easy to read instructions to a batch process. I added signal handler objects that are put in the batch process. The 2 important ones: [sigcont] - outputs a bang when pd receives SIGCONT, resumes process [raisestop] - suspends the current process They're about the shortest externals you've ever seen--It's remarkable I get something for so little effort. So, on load, I have my patch read from an shmemID to decide whether to continue running, or do handshake with the parent process to negotiate unique shmemID's for communication. After the handshake, the process sleeps and when it receives CONT, checks for message length in an shmem of length 1, and then reads the full data from a second shmemID. Since it's a stream of numbers, I can make use of FUDI. I'm pleased that it works, but haven't settled on what the interface ought to include or what other design issues there are. The abstractions that do the communication are: batchmgmt-top.pd and batchmgmt-sub.pd The included test patches are just loopback test patches that shows two batch processes sending and receiving lists. I'll work my way up to audio in a few weeks I have also included [sigtstp] a SIGTSTP handler that would allow you to patch commands to run before [raisestop] suspends the process, but it's not clear if anything's working. I made use of a wrapper script from a previous pd list thread and added a wait on the process. The syntax is a mystery to me. It was formed from some amount of stack overflow mimicry and error. The batch process stdout is being displayed in the parent process instead of being routed to [shell]'s output. Not a big deal, but it's another potential source of communication that's already provided through [shell] It seems I'm just using shell and the wrapper script to monitor the process. Is there something I don't know about pd watchdog and whether/how to sidestep it? Best, Chuck

Re: [PD] PdDroidParty: playing sound files?
by Dan Wilcox 07 Feb '20

07 Feb '20

I understand that feeling, however file playback is pretty fundamental. As for PdParty, I have put quite a lot of work into making PdParty run patches as closely as possible to desktop Pd, requiring only a couple specific steps regarding GUIs for the same projects to run on both desktop and iOS. For more advanced GUIs, it's often useful to write the guts of a project in a patch which his then opened with platform-specific wrapper patches containing the GUI. PdDroidParty cannot make as much of a promise for this regarding GUIs, but it does seem to handle most of the common use cases. > On Feb 7, 2020, at 12:20 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Fri, 7 Feb 2020 12:15:18 +0100 > From: enrike <altern2(a)gmail.com <mailto:altern2@gmail.com>> > Cc: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] PdDroidParty: playing sound files? > Message-ID: <1bacc4f2-ac0b-45d1-dc09-9b0a0c5cab60(a)gmail.com <mailto:1bacc4f2-ac0b-45d1-dc09-9b0a0c5cab60@gmail.com>> > Content-Type: text/plain; charset=windows-1252; format=flowed > > ok, thanks.

env~ argument confusion
by Peter P. 07 Feb '20

07 Feb '20

Hi, I can't seem to understand what the second argument of [env~] is for. The first argument is the window lenght for RMS analysis, but the second argument is supposed to set "period in samples per analysis (window/2 default)". It seems I am getting two analysis values per window size with the defaults of [env~ 1024 512] How would that be different from [env~ 512 512] ? Thanks for any help here! P

Re: [PD] PdDroidParty: playing sound files?
by Dan Wilcox 07 Feb '20

07 Feb '20

I have not used Android or PdDroidParty personally, but readsf~ is used by a couple of the existing droid party sample projects, ie. MultiBeat. Usage is the same as it would be with desktop Pd. You may need to add the local path with a declare if it cannot find a file: [declare -path .] Except for how the GUI objects communicate and audio is rendered, most things work the same in PdDroidParty and PdParty as they do on desktop Pd. > On Feb 7, 2020, at 9:31 AM, pd-list-request(a)lists.iem.at wrote: > > Message: 3 > Date: Fri, 7 Feb 2020 09:03:28 +0100 > From: enrike <altern2(a)gmail.com <mailto:altern2@gmail.com>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] PdDroidParty: playing sound files? > Message-ID: <483f0f48-739b-40ec-4fef-a9d9184c7c65(a)gmail.com <mailto:483f0f48-739b-40ec-4fef-a9d9184c7c65@gmail.com>> > Content-Type: text/plain; charset=windows-1252; format=flowed > > hi > > is is possible to play a local soundfile in an Android phone using > PdDroidParty?

[PD-announce] ELSE 1.0 beta 27 and Live Electronics Tutorial 1.0 beta 17
by Alexandre Torres Porres 06 Feb '20

06 Feb '20

ELSE 1.0 Beta 27 is out! Numerous bug fixes in this one, so it seems I'm now concentrating on fixing things rather than creating a bunch of new objects. This means I might be getting quite close on moving to a phase of "release candidate". By the way, I was waiting for Pd 0.51 to come out so I could use some of the new stuff (namely the new powers of inlet~), but it'll have to wait as development has been paused since xmas (hope it picks up again soon)! A heads up is that this will promote many breaking changes in several objects. The highlight of this release is the many new features and redesign I made to [else/pic], which I'm very proud now. A main fix is getting [keyboard] to work again and another nice thing to mention is that I've implemented zoom features for some of the GUI objects. See Changelog in the release notes for more details => < https://github.com/porres/pd-else/releases/tag/v1.0-beta27>. Wait a little until all binaries are available and up in Deken! I'm still waiting for a friend to send me raspberry pi binaries. The Live Electronics Tutorial has also been updated, see release notes for more info: https://github.com/porres/Live-Electronic-Music-Tutorial/releases/tag/v1.0-… Cheers _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

object opposite of change
by Csaba Láng 06 Feb '20

06 Feb '20

Dearest list, is there any object which only gives me a value from a constantly changing random numbers when it stops for a while, let's say for one second or so? I am looking for the parameters of tracking hands from Kinect like motion detector when the hands stops on an object for a while. Best, Popesz
