Re: [PD] Array in Pd version 0.32 PATCH 6 for WINDOWS NT
by Yuuta Nakayama 11 May '01

If you want creating arrays just for creating someting like buffers or look-up tables, and donot have a frequent need of those graph feature, "table" object is much more easier way to creating arrays.

RME-support in pd-0.33
by Johannes M Zmoelnig 10 May '01

10 May '01

hi miller, hi list something went wrong with the rme support under pd-0.33 the HAVE_RME define was changed to RME_HAMMERFALL therefore you have to change the line (# ??) < CFLAGS += -DHAVE_RME to > CFLAGS += -DRME_HAMMERFALL mgf.dfs.asdf IOhannes

Interapplication MIDI communication in Linux?
by Michal Seta 10 May '01

10 May '01

dear linux-pd gurus Does anyone have experience in sending MIDI from one application to another under linux? Specifically, I would like fiddle with keykit and send MIDI data to pd. Keykit has support for alsa (but since I don't have a MIDI interface for my PC I can't even test if the MIDI is getting anywhere but I get no error messages so I assume all is fine... stupid, huh?...). I was thinking that perhaps MidiShare <www.grame.fr/MidiShare> would do such tricks (it does in MacOS, anyways) but I don't even even know if it can coexist with alsa. Any ideas??? thanks ./MiS

quoting? help
by Alexander Tuchacek 10 May '01

10 May '01

hallo I would like to convert incomming numbers over midi in filnames of audiofiles, my problem is if i want to do this, its impossible to do this without a blank between '/' and the '$' sign. Is there somthing possible like quoting?, that pd ignors the character before the dollar sign? ----- | 1 ( ----- -------------------- | set open ../sound/$1.wav( -------------------- -------- | print | -------- thanks for help, alex

RE: [PD] pix_movie
by Mark Danks 09 May '01

I have looked into glTexSubImage2D, but there is a problem with using it in the gem system. Mainly, the generation of texture coordinates. The GEM geos create their own texture coordinates, and they assume that the texture goes from 0,0 to 1,1 (with the potential to wrap). With sub image, it doesn't really change how other objects would use the texture, so there would be a whole bunch of pixels which are garbage. In theory, I could extend out how objects deal with texture sizes, but it isn't there right now and would require some serious structural changes.

RE: [PD] pix_movie
by Mark Danks 09 May '01

I have sent large movies (512x256) and easily kept 60hz. This is on a machine with AGP and a lot of texture ram (the actual mhz won't make too much of a difference). The Voodoo2 only accepts 256x256 or smaller...if you try to display anything larger, it will just reject the texture and make the polygon white. pix_movie does not try to resize the texture or anything else. Also, pix_movie immediately uploads the texture, so if it isn't a power of two, you will not have any texturing. To the list, What are people's thoughts about how to handle non-power of two sized textures? My primary goal is always speed, which means that I don't like to use automatic conversions, etc. I would rather that the texture upload/whatever fail than do a silent conversion for me. However, I know that this approach confuses other people who don't know about the internals of how the hardware needs the textures....

pd w/alsa & delta44
by Bill Sack 09 May '01

09 May '01

hello list, i now have a midiman delta 44 for sound in/out. summer project to get it working w/ linux audio. built and installed the alsa drivers. i start pd with the following command: [bsack@t0ast pd]$ pd -alsa -nomidi -inchannels 4 -outchannels 4 -verbose Pd version 0.32 patch 4 , compiled 11:17:47 May 4 2001 PD-ALSA: using card M Audio Delta 44 at 0xdce0, irq 10 input channels supported: 12-12 ... etc. the "DIO errors" button is red and stays that way. the audio output is present, but choppy. the audiostatus reports: audio I/O error history: seconds ago error type 0.00 DAC blocked 0.02 DAC blocked 0.04 DAC blocked ... etc. a question for those who have had success with this card: what other command-line switches are needed to make pd, alsa, and the card happy? i have tried various combinations of -frags, -audiobuf, and different sampling rates with no discernable improvement. alsa drivers are version 0.5.10b, pd is 0.32p5. hardware is pII 350mHz. kernel is 2.2.14-5.0 (RedHat 6.2) i had a similar problem with my notebook when i tried alsa in "native mode" - it works fine in oss-emulation mode, so i use that. oss-emu mode doesn't seem to be an option for this 4-channel card, though. thank you for any suggestions, Bill -- _________ Bill Sack wsack(a)acsu.buffalo.edu ----------------------

Annoying Newbie Questions
by Timothy Rolls 08 May '01

08 May '01

Greetings! I have been working with PD for a couple weeks and I think I am starting to come along. I have a couple simple questions that may have been answered before, but I haven't found in going over the archive. 1) can a .pd created in linux work in ME? 2) Does PD work as well in 2000 as in NT? I am considering upgrading. 3) Is there a list of keywords and their explanations? I know the basics (notein, noteout, stripnote, etc.) but I suspect I am missing a great deal of them. Also, if anyone would be willing to send me examples of their work for examination, I would love to see it. I am trying to create a project that will trigger audio by inputing MIDI. I fear it may take a while. Thanks for reading and I hope I haven't re-asked too much!
