Global and Local scope for DSP~
by glerm soares 06 Nov '06

06 Nov '06

hello How could I "turn on and off DSP" of a graph, local patch or object? I know [ ; pd dsp 1 ] message work for the whole pd process... but what if I want for exemple turn on/off a bonk~ object inside a graph on a child process just when I need it? Can't I save memory with this? thanx glerm -- _________________gLeRM SoAreS.......: baixem o album do matema 17mp3 num pacote--> http://www.organismo.art.br/matema

Using csoundapi~
by Mike McGonagle 06 Nov '06

06 Nov '06

Hi all, I was checking out the csoundapi~ external, and was wondering if there was any updates to the help files. Basically, I got a copy of the external from the Csound5 distribution (there was no help file with it, contrary to what is in the manual), and the help file that I did find was from the 4.2xxx version. There seems to be a difference from what that version expects. The 'csd' file linked in the pd-instance doesn't seem to recognize that it is a stereo patch, and only creates a single audio channel. I did notice that when I changed it to [csoundapi~ 2 test.csd] that it created a stereo object. Anyway, I have not had a chance to test weather or not the other messages work with the csoundapi~ object, as I can't get the orchestra file to load. Anyone got any ideas?

Per sampleblock manipulation question
by thewade 06 Nov '06

06 Nov '06

Hello, Is there a way to do sub-block manipulation on each sample-block in real-time in PD? For example, if I have a 64 sample block and all the samples in that block are zeros except for sample 30 which is a one, and I wanted to shift all samples up 30 bins (with wrapping) so that now all samples in this block are zeros except bin 60 which is a one, how would I do that (without writing my own external)? If I understand the basic objects correctly, a simple [+~ 30] would turn the sample block above from all zeros except bin 30 which is a one into a sample block of all 30's except bin 30 which would now be a 31, right? Essential, my question is are there bitwise operators such as [>>] and [<<] exept working on samples instead of bits. Interestingly, convolution is basically an audio rate 'and' [&&~], right? Thanks for the help! -thewade

Loading externals in Linux
by Chuckk Hubbard 06 Nov '06

06 Nov '06

Hello. I'm once again trying to control my school's Moog with Pd, this time going with the serial port on my new laptop. I downloaded and compiled the [comport] external. I moved the file comport.pd_linux to /usr/local/lib/pd/extra. If I open the comport-help file, which I moved to the same folder, it opens fine. However, if I start a new patch and add a [comport] object, it is unable to load. Why does [comport] not load, while [expr] and its cousins do? Does Pd not check /usr/local/lib/pd/extra? Thanks.

measuring time with sample accuracy
by Alain de Cheveigne' 06 Nov '06

06 Nov '06

I would like to measure the time of occurrence of waveform events (for example from adc~) with sample resolution. In other words, I would like to record at what sample index an event such as a threshold crossing occurred. The aim is to time events on various inputs relative to each other with sample accuracy. I may be wrong, but I don't think things like vline~, timer or realtime can give me this accuracy. What I have in mind is something like threshold~, but that outputs the index at which a threshold-crossing event occurred. Does such a thing exist? Alain

plugin for ie/mozilla
by Andrei Thomaz 06 Nov '06

06 Nov '06

hello list, i would like to ask you if you know something about the status of projects like http://www.iua.upf.edu/~malonso/pdplugin/. It seems to me that is a great project, something that can give to some of us a great tool to make new works, but I am a bit worried if this kind of thing is having support by the pd users, or if few people are using that. In another words, do you think this kind of thing is going to be available for next years, and to have support by the community? []'s andrei

arguments of [envgen]
by ugur guney 06 Nov '06

06 Nov '06

# Hi everybody, # Today, I wanted to start to make a GUI object to create envelopes easily. I gave it the name "envgen" and immediately saw that there is already an [envgen] in pd-extended, which does exactly what I mean! So, who says finding an external is harder than writing the external itself :-) # in the help file it says that its arguments are: "xsize ysize xmax ymax send_symbol receive symbol" # but as I used it, this information is incorrect. Yes, 1. and 2. arguments determines the size on the screen but the difference of 3. - 4. arguments determines the ymax and I couldn't figure out how to set the xmax value. Do someone know about it? # And I want to thank to who have written this external. Its very fundamental and impossible to implement with standart pd, because there isn't a native object to get the mouse coordinate and button status, in order to create a new point when clicked with mouse on a canvas. (But I remember that I saw one implementation of envelope generating GUI using data structures and GOP, which needs a bang to put a new point on the line graph. But I forgot its name. I have [s-varseq] abstraction of the same author.) -ugur guney-

problems with the mac os x and Pd-0.39.2-extended-test5.dmg
by Thomas Kronlachner 05 Nov '06

05 Nov '06

Hi All, I have downloaded the package: Pd-0.39.2-extended-test5.dmg from hans page (http://at.or.at/hans/pd/installers.html). I have copiied the org.data.pd.pdlist into my preferences. I have also draged the pd apps into my application folder. When I now try to run a gem patch, I do receive a couple of errors, which indicates to me, that pd cannot find the gem application (or at least I assume this...) The errors look like the following: gemwin .... couldn't create gemhead .... couldn't create pix_convolve 3 3 .... couldn't create square 4 .... couldn't create pix_film .... couldn't create pix_texture .... couldn't create error: inlet: expected '' but got 'reset' .... you might be able to track this down from the Find menu. error: inlet: expected '' but got 'list' (just an example..) Could anybody help me please? I used to run it on my win pc, and I am very keen to get back on pd....
