    Is there any way to see the patch? I'm trying to do the same thing.

    Hello forum,

    I'm having tremendous difficulties making pix record render a video file or making pd stable for this. I tried to use the h.264 codec but pd crashes and i tried using other codecs but when i finish recording i cant play the video file and quicktime says it is not a valid file.
    "Finally when i load the video files im going to use i get this error message
    [pix_film]: loaded file: C:/Users/ardotadot/Desktop/interviu/Película 55.mov with 1 frames (640x480) at -1.000000 fps
    error: : no such object"

    I've attached the patch here so you can take a look.
    What am i doing wrong?

    Thanks in advance.
    R.A.

    Hello, apparently its pretty cool these days from what ive read. Im wondering if its possible to datamosh in pd if possible in real time, from what ive read its fairly simple (just playing with i frames and p frames) but i dont know how to do this in pd.
    Thanks in advance.

    For all the noobs out there...

    About a little more than a year ago i started this quest to conquer my dream to use Pd for audio and synthesis purposes; since nobody would teach me i decided to open a blog as an "audiovisual diary" of my struggle working with Pd, math, coding, visuals, synthesis concepts, everything that i think i need to master this program. I also wanted to open the blog so that newbies could see how easy or how hard it was to learn all this by yourself and since there is little or no info in spanish and i saw a lot of people like me trying to learn but didnt know english, i started an ongoing series of tutorials focused on synthesis and audio, so here it is...

    http://sonidiario.tumblr.com/

    the info might seem a little scattered but there is an index that will guide you through all the things ive covered since i opened the blog, i would consider this as an autobiography in progress of me working with Pd more than an addendum to all the serious, academic and incredible things that are on the web since i havent reached that level. Hope you like it but mostly i hope it helps...

    (translating in spanish...)
    Para los novatos que andan por ahí...

    Hace un poco más de un año, me embarqué en una aventura para conquistar mi sueño de utilizar Pd con fines de estudiar síntesis y audio digital; como no encontré a nadie que me enseñara, decidí abrir un blog como un "diario audiovisual" de mi lucha trabajando con Pd, matemáticas, programación, visuales, conceptos de síntesis, en fin, todo lo que yo pienso que necesito para manipular el programa al máximo. También pensé en abrir el blog para que los novatos pudieran ver qué tan fácil o difícil es aprender todo esto solo y como casi no hay información en español y cada que avanzaba veía gente como yo tratando de aprender pero que no sabía inglés, comencé con una serie de tutoriales enfocados a la síntesis y audio, así que aquí esta...

    http://sonidiario.tumblr.com/

    La información está un poco desordenada pero hice un índice general que los puede guiar a través de todas las cosas que he estudiado desde que abrí el blog. Yo lo consideraría como una "autobiografía en progreso trabajando en Pd" más que un addendum a todas las cosas serias, académicas e increibles que se encuentran en la red ya que no he logrado llegar a ese nivel. Espero les guste y sobre todo que les sirva de algo...

    im particularly proud of this one :)
    please use headphones or a nice sub system, it contains a lot of low frequencies.

    As i suspected, i wasnt able to reproduce the simple feedback fm algorithm that is in the computer music tutorial book so i came here with hope that someone could help me patch a simple feedback fm algorithm in Pd or tell me what are the workarounds with feedback in Pd so i can build it myself.
    Thanks in advance

    Hello, im trying to send a message to vline~ to read an array that has a Gaussian envelope and id like to change the values in the message dynamically so the patch reads the array faster or slower.
    I read a way to do this somewhere in Andy Farnell´s book and i remember it has something to do with a message box and "set" but i cant seem to make it work...
    I´ve attached a small patch.
    Thanks in advance.

    Hi, i recently started reading Designing Sound by Farnell and im in chapter 17 about additive synthesis. Seems like the abstractions called [spartial] and [partial] are not included in my library. Im running pd extended 0.42.5 in windows 7.

    Are these real abstractions? or are they just there to explain the concept. If these abstractions exist could somebody point me in the right direction to download them? Id really apreciatte it.
    Thanks in advance.

    Hello

    im sure most of you know how to get true random numbers from pure data but i just found out about this site and i thought i came here and share it with the community for anyone who doesnt know how and is interested somehow using this as a creative tool and whatnot.

    even comes with gaussian random number generator, integers, decimals, even a jazz scale generator...
    enjoy!

    i wouldnt know what to call this, it uses fm, am, additive, reads from arrays to do modulate a bunch of things, uses the keyboard ascii code and translates it to binary to function as switches to turn on and off the sounds of 7 different oscillators...
    just turn on the compute audio and listen to it play by itself
    you can also turn off the metro to play it with your keyboard...
    anyways i hope you like it, any comments, modifications will be greatly apreciatted.
    peace!

    hello

    how could i make a simple sine wave sound out of a trig function.
    ive come as far as writing the values in an array but i dont know how to pass those values and convert them into an audio signal.

    ive attached a patch from what i have so far.
    any help will be greatly apreciatted.

    I also tried running it under OSX 10.5.8 but it seems to be more stable on Windows.

    Found the solenoids but now i need to know how can i drive 6 solenoids with just one Arduino UNO, im thinking about using a couple of ULN2803's... any thoughts, experiencies, warnings?

    Hello,

    I was going to open a new thread but since i found this im going to ask here.
    I need to do a project for my university and i decided to build a guitar arpegiator using solenoids, kind of like a robotic guitar teacher for the right hand programming different patterns in Pd...
    I got around using Pduino with my Arduino UNO but now im not sure what are the best solenoids to use for this project...
    Help please?

    I second those lectures on khan academy. some of the videos have exercises on their website khanacademy.org and these days you can ask for a tutor, but i think the videos are more than enough.
    I´ve had the same problem since i started using pd. Id say get your hands on any math book with tons of exercises and try to solve them. Ive used engineering mathematics by Stroud, its pretty concise and might help you get started on algebra and calculus before getting deep into the scary stuff.
    probably "designing sound" by andy farnell and "musimathics" will help you start building the bridge between math, physics and sound too.

    Thank you acreil, that makes complete sense now.

    The main problem i had was understanding what [fexpr~] was doing, since i couldnt understand why would you put a mathematical expression as a filter. But i made a little research and found this paper called "a general filter design language with real-time parameter control in pd, max/msp, and jmax" (anyone can google it and download the pdf) and it explains the family of [expr] objects, and now it all makes complete sense. And as i suspected i do need a little bit more math...

    Thanks again!

    Your way sounds so much better, im not sure what fexpr and table is doing in your patch... Im starting to notice the math might be beyond my comprehension for what i want to do but im still going to take a chance and ask... would you be so kind to break it down for me?

    Well this is interesting...


    its a "bitwise rythm generator"

    OK i added a filter stage before returning the signal and it seems to be doing the trick like you suggested....
