dir access+folder listing->GUI winXP
by tom 24 Nov '03

24 Nov '03

Updated my little abstraction for listing folder contents in WINXP (or linux or OSX, but they already have PLAYLIST)... NOW has a very basic graphical interface based on input by Andrey Savitsky. http://uas.surlaplage.org/folderglider.zip Tom iamonthebeach(a)hotmail.com

looking for max/msp equivalents of some pd simple objects
by julien.breval＠tremplin-utc.net 24 Nov '03

24 Nov '03

hello I was wondering about the Max/MSP equivalents of these Pure Data objects : [tabsend~] (sends continuously a block to an array) [tabreceive~] (receives continuously a block) [block~] (choose the size of the dsp block, and overlap, for the current subpatch) [bang~] (bang after each dsp cycle, the size of a dsp cycle is set by [block~]) what would you use ? it looks like these four objects are very specific to Pure Data I am currently porting my Pd abstractions to Max/MSP, and I often use these objects, especially for spectral applications I know the FFT is implemented completely differently under Max (with [pfft~]) There are some solutions for replacing the above objects under Max (for example [groove~] instead of [tabreceive~]), but most of these solutions are millisecond-based, not sample-based ; [bang~], for example, sends a bang message "after each logical DSP cycle" of the sub-window is there a difference of accuracy between ms and samples ? if you convert an integer number of samples (like 4096) to a time in milliseconds depending on a frequency rate, you always get a floating point number, therefore a very small error ; but that error may be cumulated if the operation is repeated many times any information will be appreciated ! j

more on GOPs

hi list, look the attached picture, the objects are not positioned the same. is this normal ? (left is the GOP patch, and right is the GOP patch loaded in another patch.) also notice the "canvas>units per pixels", is this normal ? and if my another mail don't get here, the "messages" are not rendered in GOP !? pd-0.37-1 / suse8.2 cheers -andre ps. i attached the patches too ("temp.pd" just opens "GOP-video_input.pd") #N canvas 497 230 450 300 10; #X obj 137 70 GOP-video_input; #N canvas 16 231 450 300 10; #X obj 46 231 inlet; #X obj 120 229 inlet; #X obj 45 273 outlet; #X obj 119 273 outlet; #X obj 4 5 cnv 15 198 136 empty empty empty 20 12 0 14 -233017 -66577 0; #X obj 18 30 vradio 15 1 1 3 empty empty in_type 0 -6 1 8 -262144 -1 -1 0; #X text 37 29 tuner; #X text 37 45 composite; #X text 37 60 s-video; #X obj 138 71 nbx 5 14 -1e+37 1e+37 0 0 empty empty empty 0 -6 0 10 -262144 -1 -1 0 256; #X obj 270 71 nbx 5 14 -1e+37 1e+37 0 0 empty empty empty 0 -6 0 10 -262144 -1 -1 0 256; #X obj 401 71 bng 14 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X coords 0 0 1 1 200 140 1;

A few small questions
by mattn-l＠rogers.com 23 Nov '03

23 Nov '03

hello, i have two short questions that hopefully somebody will be able to answer. i'm using pd 0.37 on os x with a motu828mkII audio card. 1. is there a vst~ or plugin~ object for os x? it would be very usefull, but i don't have the programming experience to make/port one myself. 2. (this is a less important question, but something that i've been wondering about) i remember that for a while there was talk about changing pd's default font.. is this a difficult thing to do? i'm not a big fan of courier and would like to change my pd font if it's not too hard. this isn't really that important.. i was just wondering. matt. 1

GUI and such
by Matthew Nish-Lapidus 23 Nov '03

23 Nov '03

Here's my couple thoughts on this popular subject: I think that before we try to put lots of effort into making PD look nicer we should be trying to improve functionality. There are still a couple issues that keep PD from reaching its full potential, and IMO these are way more important than bitmap sliders or fancy fonts. I originally asked about the font changing just as a point of interest so that I could do something fast and simple to improve pd for my use, obviously there are other people thinking about PD's looks too. The way I see it there are a few things that keep PD back (in no particular order): 1. GUI interfering with audio -- I know this is one of the reasons that this discussion started, but I think we've lost track of that a little. 2. Audio dropouts when loading sound files -- In my opinion this is one of the largest issues in terms of using PD as a performance instrument, which I think it is otherwise ideally suited for. 3. Audio latency (i've only tested this on os x) -- can't get anything under 13ms with any hardware. So, I know I'm repeating myself a little here.. but I think that these are the top priorities for developing the audio side of PD... If any of these can be solved by changing the GUI around than that's great, but I feel like the discussion has become more about aesthetics than function. The way PD looks is important, but only after the major functional issues have been resolved. /* Matt Nish-Lapidus www.ekran.org/mn-l matt(a)ekran.org // mattn-l(a)rogers.com "What's this fish doing in my ear?" */

FOLDER ACCESS XIN XP
by tom 23 Nov '03

23 Nov '03

Made a little abstraction for listing folder contents in WINXP... I use it to preload all .wav files from a certain folder. http://uas.surlaplage.org/folderglider.zip Made from tips by Krzystof Czaja Tom iamonthebeach(a)hotmail.com

back to dir access
by tom 23 Nov '03

23 Nov '03

I wanted to work a bit on directory listing with TOT because I use WINXP. I built this patch, but it crashes often and relies on too many externals (tot, zexy, cyclone). Please take a look. >From this link (http://www.colba.net/~frederi/folderx.zip), you can download the patch (try folderx-ex/pd). Here are a few questions : 1) What is the the limit imposed by the pdgui->pd connecetion 2) my folderx.pd patch does not work because it does not handle spaces in file names! What to do? 3) check out the included jpeg... what's all the garbage???? Maybe the solution would be 1) to use TOT to find the number of files in a folder 2) then use TOT to retreive the name of one file at a time with a float message like in PLAYLIST for osX and linux. Tried to do it, but kept on crashing PD because I do not know TOT scripting. Please help! No need for a gui.

Send this to a [tot .] -> [route bang] and read from the right outlet of the route. The trickier problem is, how to deal with large lists of filenames -- there is a limit imposed by the pdgui->pd connection. I think one way would be to metro-out the filenames one-by-one? Or store them in a temporary file to be read into a [textfile]? Seems like it is a hard time without a [folder] clone... Krzysztof

Re: [PD] Pd in white on black and OSC
by tzahm＠punkass.com 23 Nov '03

> > there's a lot going on over on the csound list about OSC and csound. i > think pd is the only thing that can recieve it now. As far as I know, you can also use OSC in Supercollider. My 2 cents on PD's gui: I agree that the present gui is minimalistic, but that should maybe be seen as a plus. I would give priority to pd evolving into a full-featured audio/graphics/video processing environment, rather that striving to look cool. Tcl/tl is very portable and feels responsive enough to me even on my old laptop (Pentium 133) which is not really the best system for realtime audio. I cannot say the same about wxWindows. On the other hand, I would welcome basic preference options for things like background and font colors. On OS X, I tend to work with pd with my display set to black and white and my gamma reversed (this basically gives me a white-on-black look and reduces the eye-strain due to the monitor's light beam). You can get access to that via the Universal Access preference pane or by using the shortcut CTRL-ALT-APPLE-8 and setting your display to 256 colors. ::: sam :::

I need this object, but it seems impossible to use gate in pd with audio signal... In max, that's work !!! I need this to use rand~ with no interpolate result... Do you have idea to make it ??? Thanks ! Thomas
