PD ALSA native MMAP Interface, first implementation...
by Winfried Ritsch 10 Aug '04

10 Aug '04

Hello, PD's ALSA Interface is not working with Hammerfall RME96xx, HDSP96xx and HDSP-MADI cards, since we need this I have implemented a seperate ALSAMM Interface. I can get good latency responses (6.9ms stable) and also added multicard support. For a first try you can get it here: http://puredata.org/Members/ritsch/pd_alsa_mmap I dont know if I should or someone else will insert this in cvs (since I have no access to pd-cvs at the moment) and make maybe a alsamm branch for first implementations until several poeple have reported it stable (or noone reported it broken in one month ;-))) before do a merge. Any suggest ? Please report sucessfull usage and the configuration used. mfg Winfried Ritsch -- -- - ao.Univ.Prof. DI Winfried Ritsch - ritsch(a)iem.at - http://iem.at/ritsch - Institut fuer Elektronische Musik und Akustik - University of Music and Dramatic Art Graz - Tel. ++43-316-389-3510 (3170) Fax ++43-316-389-3171 - PGP-ID 69617A69 (see keyserver http://wwwkeys.at.gpg.net/) --

Hi Saul, as this is a flext-only related-post not referring to PD, i ask myself (and all of you): should there be a separate flext mailing list? > In regards to Max/MSP. I've set the source tree has is explained in the > read me file. > The only difference is I've set the 'Cycling74 OSX' to 'Max/MSP-SDK/4.5 > headers/c74support', is this correct?

What would these be? Do you use the flext.cw project? The settings therein should be ok. If you are using the latest flext from cvs you will need to enable "C++ exceptions" for the "language settings/C/C++-language" also, this is taken into account in tomorrow's cvs flext. I don't get that many errors when compiling flext with the newest SDK but there are a few issues with it: Some parts of the Max/MSP SDK are not compliant to the C standard. You'll get some errors for lines like #endif _MOTO_ You should changes all of these to #endif /* _MOTO_ */ The other thing is that a few things have changed non-portably from the 4.3 headers to the 4.5 headers and i have to introduce a workaround into flext for that. I already posted a message on the Max mailing list and hope to find a portable solution. I hope this all gets much easier (namely with a makefile) once i managed to try out the new Mach-O support. best greetings, Thomas

I've set the source tree has is explained in the read me file. The only difference is I've set the 'Cycling74 OSX' to 'Max/MSP-SDK/4.5 headers/c74support', is this correct? I not sure what xmax is? At the minute it won't compile and I get 1445 errors, many of which are questioning the code. I'm assuming, due to the amount of errors that there are, other setting are not configured in Code Worrier. What would these be? On another note when you say to define "FLEXT_SYS=1" is this when you are using the flext library to build externals? or is this another definition to set to compile flext itself. Thanks again All the best, Saul > >

hi list here is a bugfix of Vradio and Hradio: the source is from miller's pd-0.37-2 I exchanged only the sequence of pd_float and DRAW_UPDATE I also changed the properties-window, there was an old feature which we don't need today (new&old). the changes of vdial.c and hdial.c are attached, any changed line is labeled with /*tm*/ cheers, Thomas Musil.

Re: [PD-dev] Making Wish launch Pd rather than pd launch wish
by 0001＠ooo000ooo.org 07 Aug '04

07 Aug '04

Hi. I made a simple test some time ago using impd037A2. I added a flag to pd startup so that it started the gui communication part but not the Wish application. This seemed quite easy and harmless. Then the work appeared to be in the tcl side. Starting pd from there is also straightforward. It didin't seem that difficult to make it work, but I think it depends a lot on impd, and that version is quite old. So the question is if the newer version is near to be finished or it is actually hibernating. And of course there are all those new things in deve .... .. gerard > > On Tue, 13 Jul 2004, Miller Puckette wrote: > > > 1. pd now writes "printout" to standard error; this would have to be > > sent to the TK layer and displayed there. > > This feature is part of IMPD 0.37.A, which is rather bug-free -- it's the > version i "released" (tagged) just before beginning to go berserk. > > > I don't know how to do this in the most efficient possible way; maybe > > it's OK just to display a "text" widget and keep stuffing text into > > it. > > IMPD 0.37.A requires the console to be enabled using the -console option, > to which a scrollback length (number of lines) must be given.

memory allocation
by Tim Blechmann 07 Aug '04

07 Aug '04

hi miller, hi list, i'm currently thinking about working on the memory allocation functions of pd to make them realtime safe ... miller: are you planing to work on that in the near future? if so, it wouldn't be useful to reinvent the wheel twice ... if not, i'd start to work on that ... i thought about some kind of allocation function that allocates memory in the background and assignes pieces of this memory using getbytes() ... a helper thread could allocate memory from the os and always have a few mb as memory ... probably i would have to add a garbage collector and stuff like that, too, but it seems to be an approach that _could_ work and make memory allocation a lot faster ... and i'd like to know, what other people think of this idea, maybe i'm on the wrong way ... cheers... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 After one look at this planet any visitor from outer space would say "I want to see the manager."

RE: Flext

HI all, Has anyone managed to compile flext on a Mac (os x panther), for PD or Max/MSP. If so, what version of flext did you use and can you use Xcode or do you have to use Code Worrier. I'm getting lots of errors from the code itself (for max/msp). Are there any other help files any where. Any help much appreciated. Thanks Saul

Hi all, my radio buttons in devel_0.37 from today don't erase the last active selection when I select a new position by clicking. After some time all boxes are full. :( Does anyone know a fix for this?? Ciao -- Frank Barknecht _ ______footils.org__
