Hi Hans,

great job. But, here in XP, I get audio problems: trying to run with asio  
(as I always do with 0.42), the audio is very noisy.
Audio options are -asio -audioindev 2 -audiooutdev 2 -channels 2  
-midiindev 1 -midioutdev 1 -audiobuf 40, and they always worked with  
previous versions of pd-ext.

> The Pd-extended 0.43 release has been brewing an extra long time, about  
> 18 months now, mostly because there are lots of big improvements, and we  
> wanted to make sure we got it right, so your patches all work, but the  
> improvements all shine. Its now solidly beta, so we’re looking for  
> testers. Download a nightly build to try here:

> First off, the pd-gui side of Pd has been re-written from scratch. When  
> you run Pd, you are actually running two programs: pd is the core engine  
> and pd-gui is the GUI. Since basically all computers now come with  
> multiple CPU cores, this means that pd-gui will usually run on a  
> separate CPU core than pd, so they don’t step on each other’s toes. pd  
> can entirely take over its own core. If you want to make your patch use  
> more CPU cores, then check out the [pd~] object introduced in the last  
> release (0.42.5).
> pd still handles some of the GUI stuff, but we are working on splitting  
> that out for the 0.44 release. That is a big chunk of work but it will  
> also bring big gains. In particular, it means that it will be possible  
> for people to write their own GUIs for Pd, covering not just the display  
> of the patch, but also the editing, and everything else. You like  
> OpenFrameworks, python, iOS, JUCE, Qt, etc.? Write your own pd-gui using  
> the toolkit of your choice. That’s the idea at least. That will take a  
> solid chunk of work, so we are looking for people to join that effort.
> There are so many ideas for making a better editing experience in Pd,  
> this release makes big strides to address the editing experience. There  
> are new features like Magic Glass, Autotips, Autopatch and Perf Mode,  
> all available on the Edit menu.
> • Magic Glass let’s you magically see the messages as they pass through  
> the cords. Just turn it on and hover above a cord, and you’ll see the  
> messages as they go by. You can even look at signal/audio cords.
> • Autotips gives you tips about what an object does, what its inlet  
> expects, and what comes out of the outlets.
> • Autopatch mode automatically connects objects as you create them.
> • Perf Mode, is a mode for performance that makes it harder to  
> accidentally close windows that are part of your performance.
> The Pd Window is also majorly overhauled. First of all, its fast. Much  
> much faster than the old one. You can now print thousands of messages  
> per second to the Pd Window and still edit your patch. No more will an  
> accidental dump of info cause the GUI to freeze up (well, ok, maybe if  
> you send 10,000 messages/second but that is a way too many). There are  
> also now 5 levels of printing messages to the Pd Window: fatal, error,  
> normal, debug, all. If you are only interested in fatal errors, switch  
> the Pd Window to 0 – fatal, and you’ll only see the worst problems. You  
> want to see every single message to debug? Switch to 4 – all, and you’ll  
> get the whole firehose.
> There is also the new log library, which lets you easily send messages  
> for those different levels. And all messages logged with the objects  
> from the log library are clickable: when you Ctrl-Click or Cmd-click  
> (Mac OS X) on the line in the Pd Window, it’ll pop up the patch where  
> the message came from, and highlight the specific object that printed  
> it. That even works for many messages from other objects as well.
> The Pd Window also includes very basic level meters for monitoring the  
> input and output levels. And for those who want to play with the GUI in  
> realtime, you can type Tcl code in the Tcl entry field, and directly  
> modify and probe the running GUI.
> One thing that you can do now is customize the GUI using GUI plugins.  
> You can change all sorts of colors, some fonts, and many behaviors. Want  
> to create a new object when you triple-click? Try the tripleclick  
> example plugin Want to make the patch cords disappear when you leave  
> Edit Mode? Check out the “only show cords in edit mode” example. Those  
> are the simple ones. There is also Tab Completion, a search engine for  
> the docs, a category browser for the right-click menu, a buttonbar for  
> creating objects, and more.
> You can find many GUI plugins in the new section of the downloads page  
> as well as documentation for making your own. What kind of GUI plugin  
> will write?
