multi-speaker panning.. problamtic maths
by alexandre r. decoupigny 09 Nov '06

09 Nov '06

hello there, i am working on a pd patch for panning sound on a multispeaker setting using a usb-joystick. i am using the xjimmies library for dealing with the spatialsation. i also use the hid object joystick to the values on the x and y axis. currently i am struggling with the maths of it all. more in detail this means that the xjimmies library gives me the opportunity to controll the sound distribution on a horizontal slider. the slider outputs the values 0-360, representing the degress of a circle. my difficulties is how to match up the x and y output values of the joystick. my approach is to use angle the beween the x and the y axis, sending both values to an atan2 object. before that i extend their range from 0...1 to -1..1 i understand that atan2 outputs radiants and not degrees. if i divide atan2's output by pi and then multiply it with 180 the results are not at all, what i imagine them to be,. all i am trying to achieve is to translate the circular motion on the joystick into space.. any ideas what i am doing wrong ? (i apologize for not putting the objects in brackets, these dont live on my keyboard) best regards alexandre -- alexandre r. decoupigny

arduino-test port under linux
by Enrique Tomas 09 Nov '06

09 Nov '06

Hi! I am running pd 0.39.2-extended-test5 under linux ubuntu 6.06 and arduino. I have compiled and loaded the firmware and the Arduino IDE and it works perfect but I am having problems interfacing PD. I have used this bash trick to get the port for comport: i=0; for f in `ls /dev/tty[US]*`; do echo $i i=$(( $i + 1 )); done and I have port 52 for /dev/ttyUSB0 (that only appears when arduino is plugged). When I change the arduino-test.pd port using "open 52" I have this message: comport open -1209511136, baud -1209511136 not valid (args: [portnum] [baud]) and it is the same with other ports. I have tried to change labels using "ln -s /dev/ttyUSB0 /dev/ttyS96" but I don't succeed. At least, comport opens dev/ttyS0 but it's not my arduino board, do you know where is my problem?

Re: [PD] netpd download all patch

>> hi all, >> >> is there a way to download all the netpd-patches >> (http://www.netpd.org/NetpdPatches\)\? maybe a release each week/month? >> >> pat hi pat i know a way to do that. if got 122 patches in my netpd/patches directory and 242 in netpd/abs. some of them are testfiles and some are instruments (snyths/drums/fx). i'd say these patches are made by around 10 people. some are active and others are treasure hunting in panama :-) now to the wiki... many patches are not in the wiki and sometimes it's not the newest version. certain files are plain pd files and then we have zipped archives with many abstractions. some are on the netpd-wiki some are on other servers and just linked. i don't know the best way to store all these patches maybe cvs =? but i don't know cvs at all. the only place i'm sure (at least my patches) are the newest version is my netpd/patches & neptd/abs directory. for now the best thing you can do is connect to netpd and ask for instruments. i'd say there are people every day CEST afternoon/evening. we have weekly sessions on thursday (tonight). eni

curious Pd behavior
by Ivica Ico Bukvic 09 Nov '06

09 Nov '06

Hi all, In my recent performance, I've noticed a peculiar PD behavior. Now, before I ask for your advice, please allow me to state that the problem has not been as pronounced in the past as it was on this performance. Nonetheless, it was more or less persistent. For this reason, I am asking for your thoughts on it. Here's the hw/sw scoop: AMD64 3000+ laptop RME HDSP Multiface Linux 2.6.15 Kernel (real-time enabled, can't recall if it is preempted) ALSA JACK Pd (0.38.4) -rt running MIDI/Display interface for performer/DSP 2 x JACK-RACK with 4 LADSPA plug-ins each 2 x QSynth The entire setup consistently eats approx. 80% cpu (no spikes). Pd also had pyext (0.1.3) and a couple of simpler externals (yes, stuff is a bit outdated...). All audio is diffused (and partially processed) via Pd. What happens during the runtime is two interesting issues: 1) if I start Pd by clicking on a link (no terminal) the pyext does not output anything when DSP is on, but as soon as I turn DSP off, it spits out backlogged data. However, when I start pd from a terminal, everything works ok. Any ideas as to why? 2) when CPU usage climbs above 50%, Pd starts going out of sync by initiating opening queue twice which obviously throws entire piece out of sync. Interestingly, this only happens approx. 50% of the time (randomly). As the CPU usage grows, it becomes worse. This is not a problem when CPU usage is lower. Than 50% and never a problem when using built-in soundcard (this was not a problem before, so it may very well be that it is my setup). 3) when restarting DSP, some of the routed signal going through Pd to the output is lost at random times. This was in part a problem before as well. So, while I am aware very much that this may be peculiar to the versions I used, and/or possibly due to use of a custom (possibly buggy) build of a kernel, I was wondering if anyone had an alternative explanation for this kind of behavior. Many thanks!

[pdp]/[gridflow] trying to use a webcam
by Roman Haefeli 09 Nov '06

09 Nov '06

hi all i've run into big troubles trying to use an usb cam with either gridflow or pdp, but it doesn't want to work in both. i wonder if i am doing big mistakes or what combination of drivers and cams work with gridflow. history: # i tried two different models yet: -philips spc900nc -logitech quickcam pro 4000 both are supported by pwc-driver from http://saillard.org/linux/pwc/ . # together with that driver, there is also a usefull tool available 'setpwc', that is used to set some camera-specific settings, that are noth supported by 'dov4l', to commandline tool used to set general web-cam and tv-card settings. # both tools work fine here and i can test the various settings with the program 'camorama'. with camorama i have no troubles to display the picture from the cam and different options work fine (e.g. 320x240/30fps or 640x480/15ps). # but with neither pdp nor gridflow i had luck. for me it is more important that it works with gridflow, also because it is still maintained. that's why i post here only what i tried with gridflow # note: it seems that the according objects in gridflow and pdp [#in] and [pdp_v4l] overwrite some settings in the cam when instantiated. that makes it even more difficult to find a set of settings that just works. # my steps to get a picture with the logitech quickcam pro 4000 and pd/gridflow: -i plug the cam into the usb-plug -'setpwc -d /dev/video1 -p' tells me all actual settings of the cam: <- setpwc v1.1, (C) 2003-2005 by folkert(a)vanheusden.com Current device: Logitech QuickCam Pro 4000 VIDIOCPWCPROBE returns: Logitech QuickCam Pro 4000 - 740 Serial number: Resolution (x, y): 320, 240 Offset: 0, 0 Framerate: 10 Brightness: 32256 Hue: 65535 Colour: 32768 Contrast: 0 Whiteness: 0 Palette: YUV 4:2:0 Planar Compression preference: 1 Automatic gain control: -1275 Whitebalance mode: auto Blinking of LED is not supported by the combination of your webcam and the driver.

idea: keyboard shortcut for making connections
by Hans-Christoph Steiner 09 Nov '06

09 Nov '06

How about this for a keyboard shortcut for making connections: - select an object - type outlet number of that object - type inlet number for object to be connected to - select object to be connected to - Pd makes the connection This could be enhanced by allowing keyboard selection of objects, something like alt-tabbing between selected objects. .hc ------------------------------------------------------------------------ Access to computers should be unlimited and total. - the hacker ethic

Re: [PD] error: pix_video: could not initialise COM
by Drew Browning 09 Nov '06

09 Nov '06

Problem solved! In short, it was a service called app_filter. Disabling that service fixed the problem. Here's what I did: I went back to the advice Carmen gave a year ago about making sure certain services were running. http://lists.puredata.info/pipermail/pd-list/2005-11/032424.html Although those particular services were running I had not tried disabling all the others. There are so many services I was fearful of screwing up my machine. I guess I was now frustrated enough to try anything. I ran services.msc and disabled everything else and pix_video worked! Then I re-enabled each service until I found the culprit ... a tedious process. I have no idea what app_filter is but I hope this might help someone else if they encounter the same problem.
