I am not using anything fancy. alsa 0.9b10. I am not using a hammerfall card, but a RME 8 channel card, which is very different hardware. I used to have endless problems getting it to work, but that turned out to be IRQ conflicts. It seems that alsa has become a little more sensitive to those with version 0.9. Looking at the code, I would say that any card you can get to work with aplay should work with pd, but apperently this is not the case. Have you tried the -noadc and -nodac options ? I once got rid of similar stuck audio when I only used the output. cheers Gerard

symbolic reference and pd
by Orm Finnendahl 19 Feb '02

19 Feb '02

Hi all, is there a straightforward way to assign values to symbols and dereferencing them in pd? I think of something like a hash table or some other sort of lookuptable for key/value pairs (the key part being a symbol, the value part being an arbitrary pd datatype) in a way that you could dereference them in a similar fashion as in a tabread object (specifying that symbol table as argument and retrieving the current value of the symbol in the outlet by sending the symbol name to the inlet). I know it's possible to mimick that with send receive pairs and routes, but I would like a more elegent way to solve this. Yours, Orm

Re: [PD] linux basics and rme drivers (fwd)
by Johannes Taelman 19 Feb '02

About hammerfall DSP in linux: Try booting windows and rebooting to linux, to keep the firmware uploaded. Make sure the host-error led does not flag. At that point it may have a very similar interface as the original hammerfall. It may also not be the case. I didn't try it. I don't get very good latencies with the rme hdsp in win2k. 30 ms at 96kHz is barely usable with almost no cpu load. ASIO drivers may solve this under win2k, and that can't be far away since ASIO is available in portaudio and pd uses portaudio already. Johannes Taelman

linux basics and rme drivers
by marius schebella 18 Feb '02

18 Feb '02

hi list please i need some encouraging words... after all i decided to try a laptop-solution for pd. months (or should i say years?) of waiting until rme delivered the hammerfall multiface with a PCMCIA card-interface. it took me more than two days to configure a (fucking) new laptop with linux (it came with WinXP, oh god, i tell you... BIOS hidden, no word in the whole documentation) after loads of homepages visiting and tons of updating-files the x-server is running... but the next problem seems to be the rme-drivers. there is an oss-driver on RME's driver-CD, but only for 7 seven-days trial and no sources and precompiled for only one kernel version 2.2.99. (...). I compiled guenters drivers but i dont know how to handle the module (i think the pcmcia-card does not work properly) /lib/modules/2.4.4/rme96xx/rme96xx.o: unresolved symbol unregister_sound_dsp /lib/modules/2.4.4/rme96xx/rme96xx.o: unresolved symbol register_sound_dsp /lib/modules/2.4.4/rme96xx/rme96xx.o: unresolved symbol register_sound_mixer /lib/modules/2.4.4/rme96xx/rme96xx.o: unresolved symbol unregister_sound_mixer i also studied the correspondence on the alsa drivers for the hammerfall but as i understand, they are not downloadable yet (?). is there a place to download? any help is welcome. marius.

Gem Error creating const context
by Ben Bogart - FMPM/F1999 18 Feb '02

18 Feb '02

Hello all, I've been happily running GEM on this redhat 7.2 machine for a while now and all of a sudden I can't get GEM to create a window. Nothing has changed in the setup, it just stopped working. I tried restarting the X server, recompiling the Nvidia drivers, and still nothing. Here is the output: error: GEM: Could not open display XR error: GEM: Error creating const context error: GEM: A serious error occured creating const Context error: GEM: Do not continue! :( any ideas as to whats going on? I was planning on reinstalling this machine with debian but I was hoping to not have to do it so soon. Any pointers would be appriciated. Thanks Ben B. Bogart ---------

multithreaded externals?
by Olaf Matthes 18 Feb '02

18 Feb '02

Hi list, I'm searching for a way to make an external multithreaded. I'm currently working on oggamp~, an ogg/vorbis streaming client. The problem is that I have to receive data from the server in 4k packets and the time needed to do this is too long to place the function call inside the dsp perform routine. Is there any way provided by pd to have the receive function executed in a different thread? Or the other way round, could someone point me to code where I can see how to realise multithreading in an pd external? I tried '_beginthread' under NT but get a lot of memory related errors... Btw., a new external can be found at http://www.akustische-kunst.de/puredata/ : oggread~ reads and decodes ogg vorbis encoded files from disk. Olaf

xeq documentation?
by Larry Troxler 18 Feb '02

18 Feb '02

The documentation on the web site seems excellent, but it appears not to be in the "all-in-one" tarball. Is there a chance that you could consider putting the doc into the download as well? Larry Troxler

hi, my original advice was not to use DocBook but rather this one: don't bother with decorations, the core of information is enough. i would even add, what's really missing most of the time is a _GOOD_ help patch, although latest releases on this list proved a real concern for that, and i'd like to encourage people doing it in that way :-). another #ifndef MY_OPINION, i know.... bye, Yves/

[announce] pianoroll
by Yves Degoyon 18 Feb '02

18 Feb '02

hi, you might say i want to imitate other [ commercials] sequencers, but i needed a pianoroll object to control a sequencer. hope there ain't no patent on that. so, here it is, available for pd->linux, the port to win should be easy. cheers, Yves/ http://ydegoyon.free.fr PS : i'm glad to be free of releasing externs anytime, not waiting for a package update.
