Re: [PD] a simple example to get me started/newbie

One other thing.... If you have two PD windows open at the same time and you hit "compute audio", it will only compute audio for one of the windows (and that never seems to be the one you want!). It seems a little annoying at first because you'd think it should only compute audio for the active window. But, this becomes useful later when you start passing messages between windows. So, if you copy part of a "help" example to your project, its a good idea to close that help window before hitting "compute audio". You can make PD messages that turn on audio, rather than relying on the pull-down menu too. There are lots of different ways of doing this, but I usually do it this way: I make two "message" boxes, one for "on" and one for "off". The On button has this written in it: ; pd dsp 1 --note the semicolon The Off button is written like this: ; pd dsp 0 When you are in "Run Mode", just click on the On button to begin computing audio. You can switch between Run and Edit mode by hitting Ctrl-E (Command/Apple-E on Mac). --Josh >From: "Josh Kinberg" <jbkinb(a)hotmail.com> >To: MchZanes2(a)aol.com >CC: pd-list(a)iem.kug.ac.at >Subject: Re: [PD] a simple example to get me started/newbie >Date: Sat, 01 Mar 2003 18:33:17 -0500 > >There is a pretty good beginner's tutorial here (you can view it online or >download a PDF version): > >http://pd.iem.at/pdwiki/index.php?PdTutorial > >I'm new to PD as well, so I'm still playing around with the examples quite >a lot.

Questions + Re: [PD] Silly riddle #1
by Jordan J 02 Mar '03

02 Mar '03

Interesting little patch there. It would be nice if things like this were documented (or is it and I didn't know?) so we would know. While I'm writing a mail to the pd-list, I'll ask a few questions. Where can I find information on how fiddle~, paf~ and bilge work? Also, where can I find a copy of bilge? It didn't seem to come with whatever package I downloaded.

There is a pretty good beginner's tutorial here (you can view it online or download a PDF version): http://pd.iem.at/pdwiki/index.php?PdTutorial I'm new to PD as well, so I'm still playing around with the examples quite a lot. That would be my suggestion for trying to familiarize yourself with PD (or any programming language). Go over examples as much as you can, tweak them around and see what does what. Try combining examples together and see what happens. There are tons of examples in the Docs folder that come with PD, and you can always copy-paste them into your projects. Also, a great trick is to right-click (control-click on Mac) on any PD object and select "help". This will bring up another PD window with some instructions on how to use that object. If you right-click on an empty area on the PD canvas and select "help", it will bring up a new window with a glossary of PD objects. Hope that helps some. --Josh >From: smoerk <smoerk(a)gmx.de> >To: MchZanes2(a)aol.com >CC: pd-list(a)iem.kug.ac.at >Subject: Re: [PD] a simple example to get me started/newbie >Date: Sun, 02 Mar 2003 00:08:36 +0100 > >did you check the "compute audio" checkbox? > >MchZanes2(a)aol.com wrote: >> Hello.

pix_film+separator=pd_crash!?
by 01ek 02 Mar '03

02 Mar '03

Hello Last september, dmotd had a crashing issue with the pix_film or pix_movie when used in combination with the separator object. I'm new to PD, and also consistently crash pd when I turn on a rendering chain that has both objects. I can't find a message on the PD list archive that ever finds the problem with his patch. Did anyone figure out the problem, has it been fixed, was it just a patching issue? I get the exact same message he got: The instruction at "0X015cf58b" referenced memory at "0x0be06e8b". The memory could not be "read". Any help would be much appreciated. Alexander PS: Is there any other way to split a video image to different objects and retain each object's autonomous coordinates and values?

a simple example to get me started/newbie
by MchZanes2＠aol.com 02 Mar '03

02 Mar '03

Hello. I have no backround in programming, so trying to get past the audio test has been frustrating. I heard the test tones and the white noise in that test; I'm able to get the command prompt up (run C:pd/bin/pd.exe) as well as open up a new file from the main window. My ISP recognizes TCP/IP as a possible internet connection, so THAT appears to be turned on, though I'm "dial-up"; I keep reading and re-reading the manual and all relevant info. from other sites but nowhere can I find someone with a "simple example" to give a "wah-newbie" like me something to sink his teeth into. (If the examples in doc\2.control examples thru 5.reference are supposed to "sound", then what EXACT procedure do I need to follow to get that to happen? The same for the examples in the main manual, I get no sound generated from these examples either, though test tones work). Any help is appreciated. Thanks. My OS is WinXP.

swithc~/bang~
by marius schebella 01 Mar '03

01 Mar '03

hi, another thing is the bang~ object, which is said to send a bang at each end of a dsp cycle. but if i switch off dsp computing in a subpatch with 0 --> switch~ then there is no bang after the last computed dsp cycle. is this also intentional? marius.

re, problem solved, no bugs (neither in jack nor pd) just /me should do a mount -t clue /dev/rtfm /mnt/brain I read: > I'm currently running jack version 0.51.0. I tried with 0.44, 0.50 and 0.61 the problems go away as soon as I used the right cmd line for my card the problems went away, I use jackstart -d alsa -d ymfpci -r 44100 -n 3 # I need the -n 3 for the ymfpci and all works fine even with pd -jack -channels 8 (tested) my .asoundrc looks like this: ---- pcm.ymfpci { type hw card 0 } ctl.ymfpci { type hw card 0 } pcm.usb { type hw card 2 } ctl.usb { type hw card 2 } ____ regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

switch~
by marius schebella 01 Mar '03

01 Mar '03

hi i use switch~ 32768 which is a blocksize of 743 ms. when i start dsp in that patch it is not starting immediately, but with a variable delay of up to 32768 samples. is this intentional? btw, a help-patch for switch~ and block~ would be nice. marius.

I read: > I've got an M-Audio Quattro set up on my RedHat 8.0 system and I've been > having trouble using PD + jack and four channels. When I start jack > with the hw driver, the first two channels (in and out) bind fine in PD. > However, when I run jack using the q4b driver (4 ins, 4 outs) the > outputs bind properly.

And > furthermore, the sound I get out of the second output is coming out of > _all_four_ of my quattro outs. What's going on here? Any ideas? I suspect that this is a bug in deve_0_36 I have the same problem when I use pd with more than 2 channels on my builtin card 1st channel is silent, 2nd channel plays on both channels. just to make sure that it's not jack's fault, what version are you using ? regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.
