Re: [PD] external glitch with jack not with alsa why?
hi, update on this problem: instead of trying to rewrite the external, i was trying to use netsend (udp) / netreceive to send 17 messages (int) each 10 ms using 2 instances of pd (-nrt -nogui / pd -rt -jack). i have a strange behaviour with pd -rt -jack, i cannot click anywhere, it's frozen until i disable compute audio and then all my previous action (opening sub-patch) are working, but if i check compute audio again same problem? same goes for mrpeach external (osc). so it seems that flooding netsend / netreceive is not a good idea to avoid glitch. i have to find a way to make my external work with pd -rt -jack. this is the line that causing the glitch: nBytes = usb_control_msg(x-dev_handle, USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_IN, EDUBEAT_CMD_POLL, 0, 0, (char *)buffer, sizeof(buffer), 10); is using pthread with a buffer would fix this problem? patrick ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] pdp_rec~ crashes on ubuntu Jaunty/Pd-extended 0.41.4
i was exactly thinking that yesterday that one of the reason of the failure of linux is that people update components without testing the whole system, yesterday, an update of java fucked a few things here... so why don't you stick to stable versions ? ( e.g. hardy here ) the updates of libquicktime have always been problematic, and frankly boring... no i have no time to test on 10 flavors of linux... not to speak of osx... theora's interface is much more stable, surprinsingly, so why don't you use it it it's just for recording? ciao, sevy John Harrison wrote: Yves what distro do you run?

[PD] settings for Pure Data broken?
I've been using Pure Data with planetccrma for a little while now, and I've tried out fc9, fc10 and Centos 5.3 as platforms. I have had some similar problems on all of them, except I got PD working completely without DIO-errors only on Centos. At first this led me to believe it had something to do with Pulseaudio, since Centos comes without it. Now, after experimenting more with the settings for PD I am more inclined to believe it is a problem with PD. These are the problems I've had: 1. Connections to jack does not start automaticly. (solved) First I used different combinations of these flags while launching the program: -jack -channels 8 -r 48000 -blocksize 256. (I am not sure if any of them really do anything for the audio connection, except -jack, since the specific audio settings are done in Jack internally. I have noticed that the latency for midi will only sync with the latency for audio if I use the flag for -blocksize with a matching value to that used in Jack settings, in my case 256.) The flags did not work well, or at all. On Fedora, my system would sometimes become almost completely frozen if the auto-connection worked. Massive DIO-errors. On Centos, PD would simply not connect. I had to do it manually in the menu each time. Then I started messing with .pdsettings, found in the users home directory. I got PD to autoconnect to jack, without any flags. These were the settings I had to add/change: audioapi: 5 (unchanged) noaudioin: False (this was set to TRUE) audioindev1: 2 (added this line) noaudioout: False (this was set to TRUE) audiooutdev: 2 (added this line) audiobuf: 10 (changed it to 10, originally 50) rate: 48000 (and this was 44100) ... flags : (made sure to leave this blank since the flags seemed not to work from here. Not even the -rt flag.) So by including this in the .pdsettings file, and adding these flags to the launcher command path: -rt -alsamidi I now have a functional Pure Data on my CentOS. (remains to be seen it the same goes for Fedora). 2. Loading extra library is tricky Lately I have needed to use only one external library, namely ext13. So, I have only installed PD (0.39-3extended-rc5) + this library. It loads fine, but I am initially unable to use 'r13' (alias 'receive13'). The way I go about it is I make another object called 'send13' (included in the same library), which works fine. Then I retry making one named 'r13' or 'receive13'. Sometimes I have to repeat this order of execution until I get 'r13' to initialize properly, after which it seems to work for the rest of the session. This is a little annoying, of course. Anyone know what this is about?

Re: [PD] external glitch with jack not with alsa why? [SOLVED]

using pthread did the trick. as you can see i removed the reference to

Any strategies for treating each column of an image as an array (i. e. the array contents update based on which column of an image is loaded)? 4. Do I need something else beyond the current Pd-extended (like GridFlow)?

Re: [PD] HID problem in Xubuntu.
Hi Hans, I've been checking the archives and found only one issue that has to do with the ubuntu problem and sais to put this line: KERNEL==event[0-9]*, MODE=0666 in /etc/udev/rules.d/40-permissions.rules file. The problem is that xubuntu 9.04 (jaunty) doesn't have this file any more and permissions.rules, i think, are given in other archives... i'm looking in ubuntu forums to see what can i do... If someone knows something about... I have already tried to create the archive but it didn't work either. thanks again, Diego. --- On Wed, 7/15/09, Hans-Christoph Steiner h...@at.or.at wrote: From: Hans-Christoph Steiner h...@at.or.at Subject: Re: [PD] HID problem in Xubuntu.

But I don't think that's the issue. I think in recent versions of Ubuntu, the X server or related process grabs the keyboard and mice using exclusive access. You have to tell the X server to not use the mice that you want to use with [hid]. Check the archives, there is quite a bit of discussion about it. It would be great to have a wiki page about this... .hc On Jul 15, 2009, at 12:26 PM, Diego Azar wrote: Hi Simon, Thanks for the fast response. No, it isn't.

I installed pd-hid.deb package without trouble and everything works perfect (usb mouse, keyboard, etc) except for the touchpad. It's not a permission issue, i've already gave permission to /dev/input/event0-9 and /dev/input/mouse0-2. is your touchpad a USB HID device?

Re: [PD] question about get/set/setsize
The idea was originally so that the 'get', etc, objects could look up the field offset and type in advance to be more efficient. I've never implemented that though. AND I do want to make an out so that you don't have to specify it, anyway. cheers Miller On Sun, Jul 12, 2009 at 01:17:58PM -0700, Jonathan Wilkes wrote: Hi, I'm revising the helpfiles, and I noticed some weird behavior while looking at pointer-help.pd: 1. Hook up a [get template1 y] to the first pointer example. 2. Traverse and click next to the end of the list. 3. Get happily outputs the y field for template2 without error. Which makes me wonder- why must template names be given as arguments to get/set/setsize/getsize? Template names in [pointer] already give you traffic control. It would be a lot handier if you could just specify a field, and leave it up to the user to provide pointers to ds instances that have that field. Bonus: you could have a bunch of different ds's in a window, and poll all x and y coordinates with a single [get]. -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Searching for a new OS
I have an IBM Thinkpad Pentium III 996 Mhz 256 Mb RAM, not a great deal but still works great with Win/Pd... Now I'm looking for a free OS that works well with Pd to say goodbye to Win, any suggestions? pd- I've tried pure:dyne already but something went wrong with the video :( I just want the simplest plan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
