self-modifying abstractions
by pix 25 Sep '01

25 Sep '01

hi there, because there is no real documentation on this 'hack' i thought i'd query the pd-list hive-mind first: regarding the self modifying patches (sending messages to pd-blah.pd etc), is it possible for an abstraction to reference itself somehow? what is the name of the object that you send the messages to? my real query is, can an abstraction 'reconfigure itself' based on a parameter supplied at creation time? pix.

RE: [PD] gem & capture
by Mark Danks 25 Sep '01

25 Sep '01

Currently, you would need to modify the code and recompile. It is fairly straight forward if you have access to a compiler, but it isn't supported at the pd/gem level. Sorry about that.

[devel] why _exit?
by Krzysztof Czaja 25 Sep '01

25 Sep '01

hi, I wonder, what could be the reason of using _exit() call instead of exit() to terminate Pd in s_inter.c/sys_bail(). I do not think it is due to a fear of any malicious exit-hacks planted by developers of externals. Anyway, it would be fine to ensure flushing of streams etc. Krzysztof

Re: [PD] .pdrc (was:Can't get zexy to load)
by Timothy Rolls 25 Sep '01

25 Sep '01

I have the source code, but when I tried to compile it I got the error "could not find g_canvas" or some such thing (I know it was the g_canvas.c that was the problem). Since I was in the middle of a project I couldn't wait and figure it out, so I downloaded the rpm. However, I have some time now and maybe I'll try it later today. One thing, should I compile it as root, or as user? I think I compiled zexy as root and that's why I am having the problem with permissions. Thanks again.

[Framestein] version 0.18
by Juha Vehviläinen 24 Sep '01

24 Sep '01

0.18 - add: sending frames thru network jpeg-compressed, see example-network.pd - add: some plugins, notably xbend, bend, shuffle, tile - add: pixels-class for easy iteration thru pixels in c++, see pixels.h and green.cpp - fix: finally fixed the annoying "asynchronous socket error" when exiting pd before fs

harddisc activity blocks sound playback
by Norbert Math 24 Sep '01

24 Sep '01

hello, sorry, this one is a bit off topic since it concerns rme sound playback in linux in general... i have sucessfully installed guenters oss rmexx driver which (congratulations !!) comes officially with kernel 2.4.9 i can play back a single stereo soundfile, but playback will stutter as long as the harddisc gets busier. eg. i can't play 2 soundfiles simultaneosly under pd i 've been playing around with many combinations of pd flags including realtime and pd suid root with no results. also doctoring around with hdparm didn't help. maybe someone can give me a clue? i also tried to move the card to another slot. i wonder if it is worth to try out alsa now. win98: ok, but sound playback kept looping forever until i forced the card to use irq 5. (yes - i could use pd under win98 as a last ressort, but i am not really in the mood for it ...) again, i would be very thankful for any suggestion. norbert the box is: debian testing 2.4.9 one ide drive /dev/hda e2fs on / reiserfs on /usr and /home rme hammerfall light athlon 1.4 GHz hui:/home/norbert/pd/ac_hh# cat /proc/pci PCI devices found: Bus 0, device 0, function 0: Host bridge: VIA Technologies, Inc.

newbie: no MIDI in...
by Christian Guirreri 24 Sep '01

24 Sep '01

Hi all. I'm running the latest pd on Win98se, with an SBLive and Echo Mia. Loading pd, no switches gives me: "midiInOpen: MMSYSTEM002 A device ID has been used that is out of range for your system." I just need MIDI In, MIDI Out, and Audio Out of the Mia, all of which are #1's on the -listdev listing. After using Max/MSP for the past few years, I'm really looking forward to digging into pd. Since pd has control of multiple outs, has anyone created any surround patches? Thanks, Chris

PD->VST? (was Re: [PD] newbie: no MIDI in...)
by Christian Guirreri 24 Sep '01

24 Sep '01

Nevermind - tried after a fresh boot and everything works now (pd -midiindev 1 -midioutdev 1 -soundoutdev 4). It might be related to loading Cubase and other ASIO software first, and then pd (as one person mentioned having trouble with Reaktor installed). The sound card is an Echo Mia - wonderful card. It has eight "virtual outputs," (only stereo balanaced in and out) a super quiet 24/96 digital mixer, SPDIF in/out, simultaneous ASIO, GSIF, and DX support. Highly recommended under $200 card, though no Linux drivers I guess. Everything runs great now - thanks everyone for your replies! I can't wait to dig in...off to pure-data.org! By the way...did anyone ever get that pd VST plugin to work? I didn't understand how to setup pd to send and receive to Cubase.

GriPD questions
by Michal Seta 24 Sep '01

24 Sep '01

Hello (Joseph) I know I'm spoiled by iemlib but: Can I adjust slider min/max values programmatically (from pd)? Can I adjust FG/BG values of various items programmatically? Also, what does 'direction' field do? and what values does it accept? thanks. ./MiS
