RE: [PD] gem startup
by Mark Danks 11 Jun '01

The first error GEM: Only using 8 color bits means that GEM was only able to find a display which has 8 bit colors...I used to see this warning on old SGI Indys which didn't have the graphics upgrade. You should still be able to work, but you will see a lot of banding. I am not certain about the other message...in gemwin, the color message only has 3 arguments... Which version of GEM are you using? and which platform?

real-time audio processing
by Christoph GRONEGRESS 11 Jun '01

11 Jun '01

Hi, I'm trying to get a real-time sound analysis (fft, some time-domain stuff, maybe convolution if that works) from one or two microphone inputs working in pd. Since I'm not a sound person, I am having problems with a number of things, and was wondering if someone could help me with that. I'm slightly confused about how pd handles files, because as it seems to me there are several operators to load files, but I don't know which one's the correct one for reading from a channel. Second, whenever I connect more than two functions with each other they don't seem to work anymore, which is mainly because I don't know what input/output they assume (and the help files don't seem to know either), resulting mostly in errors. Finally, I would like to send the results to a C program: is there anything that allows me to do that other than writing things to a file, and opening it from the 'main' program? thanks christoph

Switch~ and computation amount.
by Linium 10 Jun '01

10 Jun '01

Hello, I have a large abstraction which still takes 20% of the cpu when turned off with "switch~". I was expecting that when an abstraction is turned off with switch~ its cpu usage become null. Can this be reached ? The documentation says that switch~ costs in itself a little amount of cpu. My abstraction contains other switchable abstractions, so are the other switch~ objects responsible of the 20% cpu usage, even though they belong to a top-abstraction wich is turned-off ? Should I use throw~/catch~ instead of signal inlet~/outlet~ ? Will it have a significative effect ? Best regards, Linium

connect stream socket: connection refused
by pix 07 Jun '01

07 Jun '01

hey there, i have suddenly started getting an error similar to one that came up on this list last year, but different. after running a patch of mine (which makes use of many externals, including iemlib, ext13 and d_mp3), i close pd (it doesn't seem to matter how i close it, ctrl-c, file->quit or close-box on the main pd window), and then future attempts to open pd (any patch / no patch) get the following error: $ pd rcfile option = -path /usr/local/lib/pd/externs rcfile option = -path /home/pix/sound/pd/lib rcfile option = -path /usr/local/lib/iemlib/abs rcfile option = -lib zexy rcfile option = -lib iemgui rcfile option = -lib iemlib1 rcfile option = -lib ext13 rcfile option = -lib d_mp3 rcfile option = -frags 5 rcfile option = -font 10 successfully opened /dev/dsp write-only error: failed to open MIDI ports; continuing without MIDI. connecting stream socket: Connection refused (111) (ignore the midi error, i dont have midi)... the similar error last year was about not having the loopback interface installed, i have this (i know because pd works the first time). so far, the only way i know to remedy this situation is to reboot. this is pretty inconvenient as you can imagine... and under linux... rebooting just seems wrong :) there don't seem to be any processes lying around, so i'm wondering what it is doing to my system? pix.

Pd 0.33 TEST 6 for linux released
by Miller Puckette 07 Jun '01

07 Jun '01

Hi all, Pd 0.33 TEST 6 for linux is available on http://crca.ucsd.edu/~msp/software.htm (I've reorganized the page somewhat to make this easier to find.) Main difference is bug fixes of various sorts. Between now and the "real release" I hope to make some small improvements in audio I/O and document the changes so far. cheers Miller

framp~ -- a phase vocoder ?
by guenter geiger 06 Jun '01

06 Jun '01

Hi there ! The only information about the framp~ object I found was in the help screen saying framp~ - output a ramp for each block Now I got curious for what this might be needed (I am thinking about how to implement zero padding) .. after looking at the code this seems to rather be FRequencyAMPlitude .. which means a phase vocoder analysis ... right ? Which in turn throws up the question how to do the vocoder synthesis e.g framp -> fft converter. Would be nice for high quality fft filters. Guenter

laptop multichannel solutions under linux ?
by CK 05 Jun '01

05 Jun '01

hi, this might be slightly off topic, but I guess it's a good place to ask such a question ... has any one on this list a multichannel (i.e. several stereo in/outs) working on a laptop ? what interfaces are there ? what drivers ? what's the route to take firewire ? pcmcia ? usb (yuck!) ? regards x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

multiport MIDI problems in 0.33-TEST5
by jfm3 05 Jun '01

05 Jun '01

So I have this laptop hooked up to a MIDI timepiece AV. I'm running ALSA 0.9-beta3. The beta4 card-mtpav.c file is the same as the beta3 one. I run pd-0.33-TEST5 and see the following. # pd -midiindev 2 -midioutdev 2 -nosound Pd: system call timed out Pd: system call timed out couldn't open MIDI output device 2 opened 1 MIDI input device(s) and 0 MIDI output device(s). Any pointers on how to proceed? I'm willing to believe I've loaded the mtpav driver poorly as well... It doesn't work with this # modprobe snd-card-mtpav snd_hwports=0 or this # modprobe snd-card-mtpav The parallel port is set to "bi-directional" in BIOS. I made all the other parallel port drivers loadable as modules, and none of them are loaded when I use the mtpav. (jfm3)

send receive with several $ arguments
by Linium 05 Jun '01

05 Jun '01

Hello, I notice that send and receive $1-$2 (and with more $ arg) don't work inside a patch for which such arguments are given. Only the first argument with $ sign is recognized and the other(s) seem to be translated as null. Am I right and are there any workarounds ? Linium
