semi-newbie says hello
by Alex Gottschalk 22 Apr '02

22 Apr '02

Hi all, I'm new to PD, but I used Max (pre-MSP) pretty extensively through college in the early 90s. I'm having a ton of fun right now using PD as a controller for Propellerheads' Reason using the Midi Yoke loopback device, and I'm looking forward to playing around with GEM at some point. One major question I've got; is there a simple list of all PD's objects with brief descriptions of each? I've picked up a lot already, but sometimes I've just been hitting walls because I can't brainstorm the right object name. For example, I've been trying to find a simple a/b switch (triggered by a ban) so that I can route data to either of a pair of structures, and I've had no luck. "select" and "route" don't really do that. Anyway, I'm looking forward to getting back into audio/MIDI programming for a long time to come! --Alex ---------------\_/------------------\_/------------------------------- Alex Gottschalk | algae(a)netspace.org | http://www.netspace.org/~algae/ RFC 882 put the dot in .com

comments and newlines .
by joge . 22 Apr '02

22 Apr '02

is there something special i need to do inorder to have a newline in a comment . my patches seem to forget the new line in a single comment object when i reopen my files . for instance . here is a commment and it has a newline so that the words line up nicely . then if i save the file and reopen it i get this in the comment box . here is a commment and it has a newline so that the words line up nicely . [though it might look different on your email clients but i think it conveys the idea] i am using pd for windows incase this is a windows only issue . thanks . joge .

Evaluate this please!
by Marcus Flanagan 22 Apr '02

22 Apr '02

Hello, If any of you have the time could you please take a few minutes to download and mess about with the system(attached) I've produced using Pure Data. It is the software for my final year project at University, now I have to write the 70 odd pages of the report. The report has Chapter 5 - "Evaluation and Testing" Details of what interested people think of the project. Interviews or questionnaires. HCI style thinking aloud method of evaluation. ...so any feedback from anyone would be welcome. Basically the project takes in MIDI input from a keyboard and provides a backing or melody sequence to match. Thanks, Marcus. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

I cannot boast that I could help Larry with the C involved in a new interpreter (though he said a bigger user-base than 1 would prompt him to do it), but I could help to code XML bits in Scheme.

Seriously, I see what Larry Troxler started as a very huge step towards a unified plugin(or whatever)-able architecture for PD, and watching the recent (and juicy!) thread on libraries, etc., I feel that if only we had a few more people interested in at least trying with something as flexible as Scheme <=> XML, we could really go a long way towards most everybody's desires/pleas...

[announce] forward-0.01
by Bryan Jurish 21 Apr '02

21 Apr '02

greetings all, after banging my head over possibilities for a dynamic "send", i wrote this workaround. from the README: 'forward' objects do dynamic message forwarding. Given a list as input, a 'forward' object interprets the initial list element as the name of a 'receive' object, and [send]s the rest of the list to that object. available at: http://www.ling.uni-potsdam.de/~moocow/projects/pd/forward-0.01.tgz marmosets, Bryan

GEM and g++-3.0
by Frank Barknecht 21 Apr '02

21 Apr '02

Hi, I tried building the GEM 0.87 with g++-3.0 and it complained about Pixes/pix_puzzle.cpp, that memcpy wasn't defined. I added #include "string.h" at the top of the file, but is this the correct header? Anyways, I couldn't load Gem then, it complained about a missing symbol like "xx-Gravity-xx" in it. I have my PD build with the same g++-3.0 compiler. Then I built GEM again, now with g++ 2.95.4, and that worked fine now. ciao, -- Frank Barknecht _ _______footils__
