3D tabplay?
by José Rafael Subía Valdez 14 Jul '16

14 Jul '16

Hello List, I am trying to implement an FFT Spectral Freeze patch based on "A Tutorial on Spectral Sound Processing Using Max/MSP and Jitter", Jean-Francois Charles. In the project, Charles uses the jitter objects to solve this. I am starting to play around with some ideas, but I was wondering if this is implemented somewhere. What is interesting in these patches is that the spectral freeze is dynamic so it sounds more organic. any thoughts? -- José Rafael Subía Valdez www.jrsv.net

MIDI and opensoundcontrol: type m for OSC ?
by Winfried Ritsch 12 Jul '16

12 Jul '16

Hello, 1) Had anyone experience with or used the tag type "m" for transmitting MIDI over OSC ? from http://opensoundcontrol.org/spec-1_0 : " m 4 byte MIDI message. Bytes from MSB to LSB are: port id, status byte, data1, data2" 2) Is there a defined protocol for MIDI over OSC ? 3) How to implement this in Pd ? since there are no 'm' typetags defined for [oscformat] and [packOSC] I ask, because someone want to send MIDI over OSC to my Robot-Pianoplayer driven by Pd and I do not know if this is used by other software this way, if it is "worth" to implement. mfg winfried -- - ao.Univ.Prof. DI Winfried Ritsch - ritsch(a)iem.at - http://iem.at/ritsch - Institut fuer Elektronische Musik und Akustik - University of Music and Dramatic Art Graz - Tel. ++43-316-389-3510 (3170) Fax ++43-316-389-3171 - mobile: 0043 664 2439369 --

Re: [PD] Recent PD/Gem on Windows
by me.grimm 12 Jul '16

12 Jul '16

Yeah the error I got with Pd 0.47.1/ Gem 0.93.3 is: "filmQT: Could not initialize quicktime: error -209" I DID install Quicktime and error went away but again, Quicktime on Windows is now depreciated so in the future....? Also, Pd now resides on the Desktop which is where is will be in the lab, at least for a few weeks. I had to make a relative shortcut to ..\bin\pd.exe with: "%windir%\system32\cmd.exe /c start "" "%CD%\bin\pd.exe"" also to load Gem automatically (i do not know where plist,etc. type file is on Windows to do this automatically) I added: "pd_connect::pdsend "pd startup-dialog 0 + +Gem"" to my custom foo-plugin Now at this point IT guys just have to cp folder to Desktop and students can easy just open folder, click Pd shortcut, Gem loads, etc Am I doing this all right? So far everything seems to work OK. I am getting: "Unable to connect filters -2147220969" when loading [open ../data/homer.avi} which is the win32 example in [pix_film] example..... In spite of this example DOES seem to work fine. Will need more testing though. m On Fri, Jul 8, 2016 at 10:59 AM, Py Fave <pyfave(a)gmail.com> wrote: > 93.3 should work , and is quite stable > but it's old. > > check in autobuilds. there > > http://apt.puredata.info/auto-build/latest/ > > these are auto builds of puredata+ gem + other externals > > > and tell me how it works > > I will have to do the same a bit later, > > so please keep us informed. > > some people had problems on recent gem install because of a missing dll, > that you can find elsewhere (msvcr**.dll iirc) > > > check on this list's archive. > > there are other ways , notably installing an external that lets you > download others. > > -- Deken > > https://github.com/pure-data/deken#download > > Please tell me what worked for you. > > > 2016-07-07 15:20 GMT+02:00 me.grimm <megrimm(a)gmail.com>: > >> Hello, >> >> I have not touched pd on windows in several years so please excuse it >> this has been addressed. >> >> Is there a recent build of Gem for Windows?

use of declare in subdirectory
by Alex 12 Jul '16

12 Jul '16

I have the following directory hierarchy [in the files attached]: ./dir1/dir2/dir2patch.pd ./dir1/dir1patch.pd ./top.pd In top.pd I [declare -path dir1] In ./dir1/dir1patch.pd I [declare -path dir2] and in each of the patches I print out that the patch has loaded. If I open 'top.pd' I get an error " dir2patch ... couldn't create" pd top.pd But if I open 'dir1/dir1patch.pd' pd dir1/dir1patch.pd or cd dir1 && pd dir1patch.pd I have no errors. I thought declare -path was supposed to be relative to the enclosing patch? Am I using it wrong? I'm running 0.47.1 -Alex

Pduino, firmata and SPI
by ray Y 12 Jul '16

12 Jul '16

is there a firmata vertion with at least basic master to slave SPI support? what is the fastest way to be able to use digipots with Pure Data? both digipots and digital to analog converters need the SPI protocol to operate and it is still not implemented in firmata!!! i tried using RC low pass filters for DAC conversion but the quality is terrible. are there digipots that could operate with PWM instead of the SPI protocol? or a DAC chip that will convert PWM to an analog voltage without the SPI protocol? i found myself trapped with this problem. will firmata ever have SPI support? regards r.y

Re: [PD] Granular Synthesis External
by oscar pablo di liscia 11 Jul '16

Let's leave this duty to the "really" interested users. I don't claim I did the best ever known GS synthesis external, just to put my work at the service of the PD comunity. ;) Attached to this message is an updated help file, the one I sent in this thread was not updated, sorry. May be reading this will save you some time checking if there's something you feel is new on the matter.

a multislider GUI as abstraction
by Raphaël Ilias 11 Jul '16

11 Jul '16

Hello list, I dare to share this abstraction named [ph_msl] because, I find it quite handy even though made of many mouse/dynamic-patching tricks that many pd users may find very inelegant and heavy. However, this - if you manage to make it fully work* - is an attempt to have this multi-slider GUI that I miss so much... So it's a multi-slider GUI which visual & interface properties can be saved with parent patch and modified in a windows when right-clicking > Properties (like other vanilla guis). ...and other features that I wanted : shift-clicking for smaller step, relative/jump mode like [hsl] or [vsl], histogram style bars... I often feel that pd lacks a good GUI that can be modified as an abstraction, whose graphic properties can be changed, but also mouse interaction can be redesigned, etc... I think that while you can easily "abstract" a DSP/audio or data processing (like the "list-abs" set), the process of creating a good GUI is a very "manual" process (like right-click properties every element, etc) and is limited to few GUI objects that are strong but have their limits inside the "not-puredata-code" (in C or tcl/tk) that make them black boxes. So that is an attempt to answer these issues... I love pd, but I miss some GUIs, like a good break-points curve editing (i am aware about [envgen] but it's buggy inside graph-on-parent), for envelopes or dynamic compressor ... Maybe the ability to develop GUIs in "pd language itself" would make them more customizable for the users, without having to learn C (at least, for me, I don't want to learn C). Maybe hackish-abstraction-GUI are too messy and not good in performance... maybe it would still be easier and more efficient to have "compiled" GUI... I don't know but wanted to share my experiments, and see if some have answers or ideas... Besides the debate I wish to have about GUI and pd, I hope you'll enjoy this [ph_msl] or have any remarks about it... It's packed in a zip file, and you should open "ph_msl-help.pd" first. * this abstraction was made at first with pd-Extended, but I tried to make it compatible with the vanilla+deken setup I use now and the standard external call as [library/object]. It needs the following external libraries : cyclone, hcs, iemlib, iemgui, iemguts, list-abs, moonlib, purepd, zexy best regards, Raphaël

Recent PD/Gem on Windows
by me.grimm 07 Jul '16

07 Jul '16

Hello, I have not touched pd on windows in several years so please excuse it this has been addressed. Is there a recent build of Gem for Windows? I can not seem to find one. Presently it seems that Quicktime is necessary on Windows yet I read it is depreciated(1).... I am assuming Gem 0.93.3 is usable with most recent pd 0.47.1 with Quicktime installed? I am mostly interested in any experiences/recommendations for pd/gem combination on Windows 7 as I am about to request and install in a lab environment (20 machines)... What say you? Thanks m (1) https://support.apple.com/kb/DL837?locale=en_US

[cyclone/comment] stopped working on pd 0.47-0 32 bits
by Alexandre Torres Porres 06 Jul '16

06 Jul '16

howdy, [cyclone/comment] from latest available version in deken (0.2 beta-1) works on: Pd Extended 0.42-5 Pd Vanilla 0.46-7 32 bits Pd Vanilla 0.46-7 64 bits Pd Vanilla 0.47-0 64 bits but it does not work on pd 0.47-0 32 bits - simply nothing (no comments) show up Though I'm working on cyclone, I haven't touched this object yet, I was just testing them all in the new version to see if they load (maybe I'll find more issues?). Anyway, this seems to me more of an issue related to the new pd update than the code itself, potentially affecting other codes/objects. So I'm writing this list to see what we can find that changed in the new version that would collaborate to this. code attached
