Re: [PD] Zero delay feedback, with settable send?
by Kim Taylor 12 May '07

Actually, sorry- I thought I understood this but I've got a problem with this method Considering the patch posted by Georg Holzmann (the same principle as http://crca.ucsd.edu/~msp/techniques/latest/book-html/node121.html)- Surely if the block size is default 64 samples, the delwrite atom will take at least 64 samples to write to the delay line... So the delread (next in sequence) cannot read out the contents of the delay line until AFTER this has happened? I don't understand how a minimum delay of 1 sample can be achieved (although I admit I have made it work in practice!!!) Kim

Hi, I really like this song! Looked for the song on myspace, v. nice. I can't decide whether I like the mellotron or string backings better- Strings are v sweet, but the tron is cute Going to check out more Feist tracks now :) Kim

converting (hebrew) text to numerical values?
by Cyrill 12 May '07

12 May '07

Hi list I am willing to set up a patch that could convert letters to numerical values, so i could use converted text to send data to other patches (and then produce sound). My problem is that i want to work with hebrew, and i want pd to be able to differenciate between consonants and vowels, and maybe even to be able to recognize roots within the word. As I am quite a novice concerning pd, I have no clue about the most efficient way to convert letters into values, and i dont even know if it is possible within pd? Any advice will be greatly appreciated.

Thanks for this, its cleared things up. Is there any purpose in the $0-delline2 delay line though? K

pix_record inverting image
by Tim Boykett 11 May '07

11 May '07

Hi all, I am using pix_snap and pix_record to get a series of images with decoration into a video file. This is (surprisingly enough!) working already, but with one interesting feature: the recorded videos are vertically inverted! top-bottom exchange... Hmm, any ideas what that might mean? I am using yesterday's build for OSX PPC from .hc. The problem seems to lie with pix_snap: if I connect the input pix_video straight to pix_record, then it goes through right, gets recorded right, all is well. I build a capture with pix_snap. If I look at the texture coming out of pix_snap by pix_texture-ing it onto a rectangle, then it looks right. It just gets turned upside down when it gets recorded..... Any ideas would be great. No huge loss, I am sure it a simple post-processing thing to make it look right, but I would like to know what is going wrong.... tim

Thanks for sharing! Congrats Dafydd! Feisty! I didn't know you played with Feist - great stuff and would seem to me a very suitable outlet for you to do more audio experimentation while still in a "pop" format.

Zero delay feedback, with settable send?
by Kim Taylor 11 May '07

11 May '07

Hi everyone Here's my problem: The project I'm working on requires the use of feedback loops, something I am currently implementing by using delread~/write~ in Pd with a 0 length delay. This also adds a fixed minimum delay of the block size, but this can be reduced by using block~. The problem with this- is I cannot set the destination of a delwrite~ dynamically. This is something integral to my project. -I cannot use a message box with 'set x' with a delwrite, it's not supported. I've been using this patch to do tests http://www.zen26398.zen.co.uk/temp/conn4.pd I have had success using throw~ and catch~, as the destination bus can be changed by setting throw~, BUT- throw and catch use a minimum block size of 64 and the resulting delay is too long for my purposes. I'm really stuck. Anyone got any suggestions? I thought about using arrays, they can be dynamically set. It also appears the block size can be set too, but not for tabsend~ (which is the most ideal as it continually writes). I thought that in theory I could write continuously to an array using tabwrite~ and continuously read from it using tabreceive~ or tabplay~, but I can't make it work in practice. Anyone else tried doing something similar? Regards K

(in older pd's i would have used zexy's [tabset] instead of manually unrolling the list and writing the data with [tabwrite]; you canalso do this with plain pd) as for iemmatrix, isn't it part of pd-extended? i will put a binary online today.... fmga.dsr IOhannes

That code uses Mac OS X Frameworks, so it's only for Mac OS X. There is a separate wii object for GNU/Linux based on an entirely different library. .hc On May 10, 2007, at 3:42 PM, jhonet b wrote: > JUST LINUX?? not os x? > > I already ported that code to Pd.
