I don't recall saying it wasn't possible, it's just not possible to currently "have you cake and eat it too" aka if you expect it to work like a laptop with all sorts of IO & RT audio ... it aint happening :P. People have something working, Autostatic for instance. The problem, from what I can tell so far, is that their setups basically disable as much as possible on the pi and *only* use the usb bus for audio. That will in fact work with few dropouts. If you (and I), desire to use any sort of usb device with audio, lets say midi or ethernet or a mouse and keyboard etc, then this setup will not work without dropouts based on how the pi firmware currently works with usb. My setup requires all sorts of usb input, so it basically will not work. Again I find this ironic considering I managed to do this with 10 year old hardware with fewer resources than the pi years ago. The pi is great for what it is, but it's not currently tuned for *real* usb audio. I'm thinking beagleboard but am hopefully biding my time until the pi folks can work in the fix.

New book - Multimedia Prorgamming with Pure Data
by Antonio Roberts 28 Jul '13

28 Jul '13

A new book by Bryan Chung on programming in Pure Data has recently come out. It focuses on GEM, which is a nice change from the usual focus on audio. www.packtpub.com/multimedia-programming-with-pure-data/book Preparing interactive displays, creating computer games, and conducting audio-visual performance are now achievable without typing lines of code. With Pure Data, a graphical programming environment, creating interactive multimedia applications is just visually connecting graphical icons together. It is straightforward, intuitive, and effective. "Multimedia Programming with Pure Data" will show you how to create interactive multimedia applications. You will learn how to author various digital media, such as images, animations, audio, and videos together to form a coherent title. From simple to sophisticated interaction techniques, you will learn to apply these techniques in your practical multimedia projects. You start from making 2D and 3D computer graphics and proceed to animation, multimedia presentation, interface design, and more sophisticated computer vision applications with interactivity. With Pure Data and GEM, you will learn to produce animations with 2D digital imagery, 3D modelling, and particle systems. You can also design graphical interfaces, and use live video for motion tracking applications. Furthermore, you will learn Audio signal processing, which forms the key aspect to multimedia content creation. Last but not least, Network programming using Pure Data extension libraries explores applications to other portable devices. *note: I was one of the reviewers -- ============================ antonio(a)hellocatfood.com http://www.hellocatfood.com ============================

polygate~, demux~ mux~, mtx_*~
by puredata＠11h11.com 28 Jul '13

hi, i need to route "1 to x" & "x to 1" audio signal. demux~ (demultiplex~ on pd-extended) and mux~ are doing exactly that, but when switching using a number box = glitch. polygate~ have a fade option that avoid this glitch but there's no couterpart (like unpolygate~) and finally mtx_*~ on pd-extended linux 64, i cannot create the object (i don't know what to import). any advice?

Re: [PD] Raspberry Pi Behringer UCA222 boot problems
by Dan Wilcox 27 Jul '13

27 Jul '13

Simply put, the RPI firmware does not work with USB audio correctly yet. See this thread: http://lists.puredata.info/pipermail/pd-list/2013-07/103261.html I keep looking for fixes, but the way USB is handled, the only way for it to work without dropouts is to have *nothing* else plugged into the usb bus and ethernet disabled ... sucks.

I have installed the OS on the PdPi site and updated it. I am using a Behringer UCA222 for audio. When I change the USB speed down to 1 (dwc_otg.speed=1) in /boot/cmdline.txt my Pi won't boot with the soundcard plugged in. If I unplug the soundcard the Pi will boot but as soon as I plug it in the Pi crashes. Has anyone got any suggestions about why this is happening? > > Thanks, > John -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

Re: [PD] l2ork: SSSAD loads but doesn't save presets
by Dan Wilcox 27 Jul '13

Yeah, I have an old version of SSAD. I'm slowly rewriting everything to rely on rjlib, so eventually I'll remove it.

Re: [PD] Building Pd App on OSX

Wee. You're lucky I just did a bunch of low level library compiling stuff on OSX/iOS for OpenFrameworks ...

By specifying multiple architectures, OSX will build a "fat" lib that supports them in a single binary. i386 + ppc is the old "universal binary/lib". The new 10.7+ format is i386 + x86_64 so I'd suggest dropping the old format now as the vast majority of people are using newer Intel machines. > * Why is there -isysroot?

For newer Xcodes, there is a commandline util that returns the path to the Xcode developer root: xcode-select -print-path. With Xcode 4.6, it returns: /Applications/Xcode.app/Contents/Developer For example, with the 10.8 SDK you can use this: $(xcode-select -print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/ Naturally, you can do a search in that SDKs folder and choose the last one to build for the latest SDK or simply use a shell variable: OSX_SDK_VER=10.8 SYSROOT=$(xcode-select -print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX$OSX_SDK_VER.sdk/ > * Any hint what -isysroot should be to find something as > common as stdlib.h? Yes, it contains all of the includes and libs for that particular SDK. > * Is "make -f makefile.mac" supposed to compile using cc, gcc, or something else? gcc should be fine for now, you could target llvm-gcc if you want, but gcc isn't disappearing complete in the meantime. -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

l2ork: SSSAD loads but doesn't save presets
by András Murányi 27 Jul '13

27 Jul '13

Dear List, I've been having a problem with SSSAD for a few weeks: it's able to load presets, but when it comes to saving, an empty state is written (i mean, it does write but it overwrites the previous content of the preset with nothingness). The example patches don't work either. There are no errors in the console and I have also overwritten the whole SSSAD folder with a newly downloaded one, still no joy. Tested in vanilla and it works.

Gem compiled without FONT-support
by Alexandros Drymonitis 27 Jul '13

27 Jul '13

I've compiled Pd-0.44.3 on Ubuntu 12.04 and compiled the Gem library as well. Thought all was good (ok, I have some issues with the camera and a couple of other stuff, but it's not of my interest at this point), but when I opened a patch I made some time ago I got this error: [text2d]: Gem has been compiled without FONT-support ! Any idea how to fix this?
