integrating loaders into Pd-extended
by Hans-Christoph Steiner 26 Dec '07

26 Dec '07

Hey all, Merry whatever you might want to celebrate! :D For the next release of Pd-extended, it would be awesome to have it include all of the various loaders, things like hexloader, tclpd, pdlua, haskell, CLR, etc. I won't have time to do it myself, since I am committed to getting a bunch of other things working for the next release, but I can definitely help. Anyone interested in working on this? .hc ------------------------------------------------------------------------ ---- Looking at things from a more basic level, you can come up with a more direct solution...

oscillator lib
by Hans-Christoph Steiner 22 Dec '07

22 Dec '07

There are a number of standard oscillators used in synthesis, I think it would be very useful to have a standard library of them. I think at this point there are already implementations of all of the oscillators that I can think of, what needs to be done now is to define a standard interface and naming scheme, and collect them into a standard library. One question I have is whether they should all be bandwidth-limited, based on the current sample rate, or whether this library should have both versions. Anyone interested in working on this? I think this would also be a building block for the standard synth lib that Ed is proposing. .hc ------------------------------------------------------------------------ ---- ¡El pueblo unido jamás será vencido!

zexy/[regex] : allow backslashes ?
by Alexandre Quessy 21 Dec '07

21 Dec '07

Hi IOhannes and the list, I am looking (and wrapping) zexy/[regex] and I was wondering if you could add a way to be able to use backslashes. They are very useful in regex, but pretty much forbidden in Pd. Though, I am not sure that they are so useful with POSIX regex, which is what zexy/[regex] uses.(#include <regex.h>) I suggest to use backticks as a backslash replacement, since they are allowed in pd. That is what I have done a little while ago in externals/aalex/pcre.c An here is how I replace backticks by backslashes. (There are dozens of better ways to do this, of course) ------------------- char *mask = _str_replace('`', '\\', pattern); /** clone of the PHP function */ char *_str_replace(const char search, const char replace, const char *subject) { int i, len; char *result = strdup(subject); len = strlen(result); for (i = 0; i <= len; i++) { if(result[i] == search) { result[i] = replace; } } return result; } ---------- ---------------------- Alexandre Quessy http://alexandre.quessy.net http://www.puredata.info/Members/aalex

Shell and long-term instability
by B. Bogart 21 Dec '07

21 Dec '07

Hey all, I realized that [shell] seems to be doing some strange things, once I have removed it from my PD the patch runs much better now. I realized this due to a very high chance that a crash would happen just after a shell command is issued. Has anyone else seen this? I would not cause it a crash per-se, but I can say that oprofile says that no-vmlinux is using 97% CPU, and both PD and X are stalled. I don't have time to investigate further now, but I'm wondering if other people have seen stability issues with shell on linux for long-term installations? Thanks all. FYI I'm back to my 480000 item message... things going ok so far... ;) .b.

Prelude and Introduction
by Mike McGonagle 19 Dec '07

19 Dec '07

Hello all, I just wanted to give a quick introduction of myself. My name is Michael McGonagle, and my childhood nickname is "Mogo", a name that has stuck with me as there are just too many damned Mike's in the world. My mother was a nurse and played the piano, her favorite thing to play was "Clair de Lune" by Debussy. It was from here that I got my love for music. We got a piano when I was about 12 and I would get home every day after school and just play, teaching myself how to both play the piano and composing simple tunes. I think I pissed off my father for not just the amount of time that I played (sometimes as much as 6 hours in the evenings), but also for the fact that I liked to dismantle the piano, removing the covers so that I could get access to the insides of the piano. My first love in music was Beethoven. Next came Bach. It was a long time before I was able to appreciate 20th century composition, but since that time, I have learned what things I like and what I don't... My list of favorite composers range from Stravinski, Subotnick, Stockhausen, Webern, and many others. A professor that I had in school got me interested in electronic/computer music. He had built his own computer that did brain wave analysis (for a doctor friend of his), and he also used it to create some very rudimentary music. I started programming back when the Comodore 64 was in its hey day. Working in assembler was probably my favorite thing (the Assembler program, while I don't remember the name of it, it was one of the best programming packages I have ever used). I started to teach myself C in about 1990, and found an interest in writing other languages in C. I started off with a Forth interpreter, and used it to create a very rudimentary composition package for myself. (That was about 1992). I moved on to learn Java, and I tried to learn C++ (but there was just something about it that seemed perverse in comparison with C, I will admit I LIKE POINTERS!). I think one of the things that attracted me to Pure Data was the fact that it is written in C, instead of C++. As I work in Graphic Arts, I got interested in writing a PostScript interpreter in Java. I would say that I still am working on it, but it has been a couple of years since I have done anything with it. It is a fully functional programming language, it just doesn't have any of the graphics primitives that would make it PostScript. I have been using Pure Data for about 5 years now, on and off. I also have an interest in fractals, and specifically 'strange attractor' types of equations. I had written some object classes to deal with these sorts of functions, and when I found that Ben Bogart had began a library called Chaos in Pure Data, I worked to expand that library to not only include more attractor equations, but also added the ability to search for other parameter sets that would result in a chaotic stream (it wasn't perfect, but it worked for some of the attractors). I don't really compose much anymore for "real" instruments. My goal is to set up some things in Pure Data that deal with granular synthesis using Sine Wave generators (ala Stockhausen's Studie No 2), drive them using various fractal equations, genetic programming techniques, or some other form of stochastic controls. Currently, my most immediate goal in Pure Data is to create an SQL front end that allows the storage of arbitrary data in a database. Once that is "complete", I want to revamp all of my previous projects to take advantage of using an SQL database to store "compositions", etc. I have created a front-end for working with Chaos, but as it doesn't have an easy way to store and recall various parameters, I got frustrated in trying to release the code. This is one thing I want to rework, as I think it will be useful to others who are also interested in fractal generators. Wow, sounds like a lot, and I guess it is for my 45 years on this planet. I will say that it has been wonderful having access to not just Pure Data, but the community that has built up around the program. Michael "Mogo" McGonagle -- Peace may sound simple—one beautiful word— but it requires everything we have, every quality, every strength, every dream, every high ideal. —Yehudi Menuhin (1916–1999), musician
