Now in Pd, they don't match, [cartopol~] gives inverted phases, but [cartopol] in Pd matches the [atas2] and [expr] versions. And the results in MAX also are in agreement to [atan2] and [expr] or [cartopol] in Pd. So Pd's [cartopol~] is the odd one out. i'm not sure i can follow. i think there is still some information missing. in Max, [cartopol~] and [cartopol] match. in Pd, [cartopol~] and [cartopol] are inverted. this really means: cyclone's [cartopol~] is inverted with respect to the [cartopol] you are using. cyclone's [cartopol~] is to match Max's [cartopol~], phase wise. if it doesn't, then it's a bug in cyclone. so as a first step, you should check whether they output the same in Max and Pd/cyclone, if you send them the same input. i don't know, where your [cartopol] implementation comes from. if it comes from cyclone, then it must match Max's [cartopol] implementation. if it does not, it's a bug in cyclone. if Max's [cartopol] and [cartopol~] behave differently (which they don't), then cyclone's implementations must behave differently as well. however, if the [cartopol] you are using is _not_ from cyclone, this doesn't matter at all. e.g. zexy's [cart2pol] doesn't care at all about Max and cyclone compatibility; i don't know whether they behave the same and if they don't then i'm sure i wouldn't change [cart2pol]s behaviour (as it is designed to be mathematically correct, not to be Max compatible) fmgasdrt IOhannes signature.asc Description: OpenPGP digital signature ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Wiimote, Kinect for Windows/pd
Yep, I know of people who've used Glovepie for Windows. I use OSCulator on OSX and it is so easy to use and brilliant. I'm pretty sure there are externals that should work (sorry I can't be more specific, I gave up looking after I found a workable solution) One thing I will say is that Macs (imac and macbook pro) have some (not predicable) issues with internal bluetooth seriously failing. This was so bad I changed my usb external soundcard to a firewire version. This mostly solved the problem which only happens once in a blue moon now.

Holiday release. In the latest version of Linux Laptop Orchestra's in-house version of Pure-Data we've squashed a number of lingering bugs, as well as added some exciting new features, including: *infinite undo that covers all editing actions (while some externals with custom dialogs may require minor adjustment to their code to work with the newfound undo, most of them will work out-of-box). Great! *more robust paste from external clipboard. copying pd scripts from an email and pasting them directly into a canvas has never been easier. Does pd scripts mean a patch's source code? *multiple entry bug that has been plaguing pd for years has been finally squashed. *resizing GOP window via gui (just like the rest of iemgui objects). That's very handy. *a number of usability improvements in terms of pasting logic and other editing features (e.g. gop resize via gui now prevents users to make it smaller than its text size unless hidetext is enabled, objects are automatically resized (except for gop objects with hidden text for obvious reasons) to accommodate adequate spacing for inlets and outlets, etc.) *all known graph-on-parent redraw issues have been addressed and gop redrawing is now as robust as it has ever been. *and many more... (see Changelog and git logs for more detailed info) If interested, head to http://l2ork.music.vt.edu/main/?page_id=56 to download 32-bit builds, source, and more.

Re: [PD] 0.43 preferences flatspace
Those libs are added to the global path when the libdirs are loaded globally. Its from an old hack. Libraries should really be loaded local to each path, then that would make those all go away.

Re: [PD] number to fractions external?
I just gave this a go, and here's what I have so far based on the Wikipedia link Claude gave. Send the decimal through the left inlet, and it outputs the numerator and denominator as a list. The argument is the maximum value the denominator is allowed to be, which keeps it from going crazy trying to figure out irrational numbers and also seems to make up for some floating-points errors. You can change the max with the right inlet as well. Right now it defaults to 100, but that may be too low. Higher values=more accurate, but potentially more computation. I haven't implemented the rules for decrementing the last value of the continuous fractions, so it's not perfect. But it does give 355/113 for pi. :-) .mmb On Fri, Dec 16, 2011 at 2:46 PM, Jonathan Wilkes jancs...@yahoo.com wrote: From: i go bananas hard@gmail.com To: Ludwig Maes ludwig.m...@gmail.com Cc: pd-list@iem.at Sent: Friday, December 16, 2011 1:16 PM Subject: Re: [PD] number to fractions external? if you had read the thread, you would have seen that claude posted a link to that technique. now go and make a PD patch that does it, mr smart guy.

Holiday release. In the latest version of Linux Laptop Orchestra's in-house version of Pure-Data we've squashed a number of lingering bugs, as well as added some exciting new features, including: *infinite undo that covers all editing actions (while some externals with custom dialogs may require minor adjustment to their code to work with the newfound undo, most of them will work out-of-box). Great! *more robust paste from external clipboard. copying pd scripts from an email and pasting them directly into a canvas has never been easier. Does pd scripts mean a patch's source code? Yes! *multiple entry bug that has been plaguing pd for years has been finally squashed. *resizing GOP window via gui (just like the rest of iemgui objects). That's very handy. *a number of usability improvements in terms of pasting logic and other editing features (e.g. gop resize via gui now prevents users to make it smaller than its text size unless hidetext is enabled, objects are automatically resized (except for gop objects with hidden text for obvious reasons) to accommodate adequate spacing for inlets and outlets, etc.) *all known graph-on-parent redraw issues have been addressed and gop redrawing is now as robust as it has ever been. *and many more...
