Pd EPI clarification
by Krzysztof Czaja 21 Nov '01

21 Nov '01

hi, in Pd proper, there are many globals seen by linux externals, but which are hidden from `nt' dlls, because of the lack of explicit exporting directive. I would like to use the routines: binbuf_match(), canvas_obj() (and probably also the outmidi_ set), and the variables: subcanvas_class, and newest, while retaining the possibility of a future `nt' port. Are they part of PureData EPI (externals programming interface) or their omission has been intended? Krzysztof

pd + scalars:: bug (fix)
by IOhannes m zmoelnig 21 Nov '01

21 Nov '01

hi miller, hi list ! using pd with the ("experimental") scalar object is painful, especially if you (like me) are trying to use it in abstractions that are used more than one time. the problems are: 1) all scalar-objects (like "set" or "get") add the leading "pd-" per default. thus you cannot use "namecanvas my_template" within the sub, since the "set"(...) routines will fail. the "scalar"-object itself does *not* add the leading "pd-". so you have to create objects: "scalar pd-my_template float X" and "get my_template X" to address the same template. i do not think that this is consistent. it is not possible to use multiple namespaces within a subpatch (with "namecanvas"), which is ok, but does not help to work around the inconsistency. 2) when creating a subpatch like "pd my_template" a namespace "pd-my_template" will be created. however, this does not work with $args, so "pd $0_template" will create a namespace like "pd-$0_template" instead of (for instance) "pd-1001_template" i considered these as bugs and tried to fix them:: so now the behaviour is as follows: 1) the "scalar"-object does prepend a "pd-" to it's first argument like the other traversal objects 2) the $args are correctly expanded for the namespace of a subpatch i fixed the help-files (5.reference/scalar.pd and 7.stuff/data-structures/8.panel.pd) accordingly. the patch does not fix the instability of the traversal/scalar-objects !! (so it will keep crashing when used ;-) since i am going to use this heavily now, i hope that i could make it into the next release (or something similar, that let's me use multiple abstractions with templates and drawings on the parent-patch) mfg.csd.asdf IOhannes the patch is attached and (or alternatively the source-code) can be found on ftp://iem.kug.ac.at/pd/misc/ mfg.cds.sdaf IOhannes

Compiling Gem under Linux RedHat 7.1
by Martin Dupras 21 Nov '01

21 Nov '01

Hi, I'm slowly migrating to Linux after using Irix for a few years. I've got PD working (sort of) and I'm trying to get Gem to work with it. [Sorry if this is a Gem rather than a PD question.] I downloaded gem 0.84; I added the libraries it says it needs, and follow the build instructions. However, when I run the ./configure script I get the following error: "configure: error: library gltt not available - run ./makeauxlibs script" which is strange considering that I have just installed gltt from an rpm distribution. Also, on an only slightly related subject, does anyone have any experience running a dual-processor machine with Pd and Gem? I would like to know if anyone knows the best strategy to adopt for kinda guaranteeing good real-time performance by explicitly attaching processes to processors. Many thanks, - martin

and usb audio
by Olaf Matthes 20 Nov '01

20 Nov '01

Hi list, I remember a post a few month ago concerning problems running pd with a tascam usb-audio interface. I'm thinking about buying a usb audio interface (emagic emi 26) because I need 4 channel audio out with a laptop. Are there any known problems with this or other usb interfaces in general (when used with pd under Win98SE)? Any suggestions what to buy (instead)? - The laptop has no firewire, that's why I have to take usb... ;-( thanks Olaf

PD & hardware
by Daniel Hug 20 Nov '01

20 Nov '01

Hello list, I worked w/MAX already and now I'm evaluating PD for a interactive installation. The system will play multiple soundfiles over 8 outputs simultaneously. The sample playback is modified real-time by the properties of sound that is recorded over microphones on 8 other channels (possibly fft?). The mapping of in and out is partially dynamic. My questions are: does PD work with other HW than hammerfall (win or linux)? Can I use DSP cards with PD? And witch OS is generally recommended (not to hack PD, but to have a easy-to-handle and efficient system for a short time project)? How's the overall performance with multiple simultaneous in and outs/sound analysis/realtime sample playback, especially compared to MAX on an apple? Many thanks for your help! I really hope to be able to use PD as a opensource sound solution. daniel

in \pd\doc\2.control.examples\15.array.pd it references a file 13.file.txt which seems to have been renamed to 15.file.txt cheers, Joschi ________________________________________________________________ Josh .. Yoshi .. Joschi .. xiphoidprocess.com .. eds.org/~joschi

hardware question ASIO
by Kenric McDowell 20 Nov '01

20 Nov '01

Hi, Has anyone used Echo products with Pd? Just curious if this is possible without Pd ASIO. Sorry if this is redundant, I couldn't find anything in the archive. Thanks, Kenric McDowell
