prepending osc messages with a tag
by Peter Plessas 17 Aug '10

17 Aug '10

Dear List, how to prepend an OSC message with a (ideally settable) tag? [/sheep 4> | | | [magic-object /animal] | | resulting in: [/animal/sheep 4< A normal [prepend] does not work as it includes a whitespace. A [makefilename] will not work with OSC messages of varying length and content. The [prefix ...< message of [packOSC] is not usable in my case. Looking forward to good and inspiring ideas! P

FM Synthese in Pure Data
by hghoyer 17 Aug '10

17 Aug '10

Hi, I try to understand the FM synthesis with Pure Data. A simple FM synthesis is understandable.But what about a more complex FM synthesis? I once created a simple patch. Can someone tell me if that is really FM synthesis? Or I do something wrong? Dear .hg

Infinite and NaN float values?
by Matteo Sisti Sette 17 Aug '10

17 Aug '10

Hi, I've found out that making a float grow and grow and grow it eventually reaches a value that is displayed in number boxes as "+Inf". Then if I multiply that number by 0 I get a value that is displayed in a number box as "NaN". Is this expected behaviour? If so i guess infinities and NaN have been recently introduced, haven't they? However there seem to be some inconsistency: 5/4 returns 0 (as I was used to), not +inf. Also, I'm not sure +inf is the value you expect when adding something to the greatest representable value... or is it? Also I cannot seem to find a way to write inf's or NaN as a literal (in a message box), and I cannot find an [isNaN] or similar object... that's why I wonder if this is a feature or a bug. Also, sliders seem not to like them. If you feed a NaN (or maybe +Inf, I'm not sure) to a slider, it makes the cursor disappear (which is probably OK for NaN), but then you suddenly get weird behaviour of the window: a scrollbar with a very small cursor appears as if the patch window had become suddenly huge and it may scroll away so you cannot see the patch content any more and you may not be able to scroll it. It seems like it is actually trying to draw the slider's cursor far away, which doesn't happen with huge but finite numbers.... I'm trying to build a simple test patch, but I'm having difficulties. I can reproduce it with a patch that is pretty simple but doesn't quite isolate the "issue" (or non-issue) in a decent way. I'll post it if I cannot end up with anything better Cheers m.

Here's an object list I dynamically created, relying on the PDDP tags that I added to each patch. http://puredata.info/Members/jwilkes/object-list/view It makes use of pddp/helplink (although I'm finding that for objects that all share a common help patch, like [cos] and [sin], helplink doesn't work). It's in order of file name, so it's not quite alphabetical. But rather than a big static list, I'd like to see a nice object search function that can generate a list relevant to the user. (Especially when searching for externals.) -Jonathan > > _______________________________________________ > Pd-list(a)iem.at > mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list >

[SOLVED] process control: startup priority/cpu weirdness?
by Damian Stewart 16 Aug '10

16 Aug '10

solved - on ubuntu or any other system without inittab, the solution is to edit (eg) /etc/init/ttyS2.conf and change where ttyS2 is one of the ttys - in my case, it's the built-in serial connection on the beagleboard. exec /sbin/getty 115200 ttyS2 to something like: exec /sbin/getty -n -l /usr/bin/autologin 115200 ttyS2 where autologin is a tiny c program: int main() { execlp( "login", "login", "-f", "your_user_here", 0); } then add the program you want to run to the bottom of ~/.profile ... cheers! damian -- damian stewart . @damiannz . damian(a)frey.co.nz frey . contemporary art . http://www.frey.co.nz
