Re: [LAU] [PD] ANN: pd-l2ork 20120226 snapshot now available

> Great! One question: what is "implemented gop legacy redraw" about? Great question. Since January pd-l2ork by default moves gop/array/scalar groups of objects via tag. In layman terms this means instead of having to redraw entire gop object every time it is moved even by one pixel (e.g. dragging gop with mouse would generate dozens of these events per second), moves it all with a single tcl command. This newly implemented feature however did not account for objects that do not support moving by tag (mainly 3rd party gui externals that do not have moving by tag implemented). This has made gop displacing with such objects embedded not work properly for the said objects. So, now if you have a gop object that also includes one of the said 3rd party gui externals, it falls back gracefully to the old way of redrawing the gop object which is terribly inefficient but at least it works seamlessly for both cases. >From L2Ork's perspective, we use almost exclusively built-in iemgui objects for all our needs with the ggee/image being one notable exception that has been also updated and cleaned-up for this release, including support for moving with tag. To give you some perspective just what kind of a difference this makes performances-wise, make a gop object that has iemgui/vanilla objects only, and then create another with the ggee/button object (for instance) and observe the difference. For a really fun experience try running pd-l2ork with -d 1 debugging enabled to see the console printout difference. Hope this helps! P.S. if there is an exhaustive list of 3rd party gui externals and their breakdown between those that are well supported and those that are not, this would be particularly helpful as I could then try to tackle them one-by-one until they've all been revamped. NB: text objects and other 3rd party externals that don't have custom guis are supported out-of-box even prior to the aforesaid fix.

This release includes following fixes: *MyCanvas does not become invisible if it is partially visible in GOP mode *copy-paste from console does not work with the ctrl+c shortcut *Proper focusing out of the selection (where typing into .printout console makes problems for textedfor objects) *Resizing window when text is hidden still prevents resizing below the text size *GOP resize hooks should be visible only if no object is selected *when re-saving prototype abstraction it disappears on the parent canvas *disis_wiimote does not re-detect motion plus every time when re-connecting and re-enabling the extension (partially fixed (needs update to libCwiid, will be updated soon)--for the time being, easiest thing is to enable extension twice; NB: this will not be necessary once the libCwiid is updated) *image and other non-vanilla objects do not translate with the GOP *ggee objects button and image updated, gcanvas disabled as it has too many bugs to be worth fixing (IMO) *implemented gop legacy redraw *selection as part of the infinite undo (for those tricky selections that take a while to do and can be messed up with a single mis-click) NB: ctrl+a is currently ignored, mainly because it is easy to do but will be likely addressed in the next release L2Ork now also supports builds for both 32-bit and 64-bit Linux systems and can be downloaded from the usual place: http://l2ork.music.vt.edu/main/?page_id=56 Bug reports are in high demand, so get busy and let me know of any potential hiccups. -- Ivica Ico Bukvic, D.M.A Composition, Music Technology Director, DISIS Interactive Sound& Intermedia Studio Director, L2Ork Linux Laptop Orchestra Assistant Director, CCTAD Virginia Tech Department of Music Blacksburg, VA 24061-0240 (540) 231-6139 (540) 231-5034 (fax) disis.music.vt.edu l2ork.music.vt.edu ico.bukvic.net

What Debian should we install, to get a working system? Go with stable if you use NVIDIA, you are an idiot if you use NVIDIA, use Intel and install Debian, but not stable :D??? Cool!

We, the Linux community seemingly are trapped into a graphics issue. I like to cross post this and I won't add any comment.

Yes, the xorg.conf is switched at startup.

A KDE session for Mint Lisa won't start anymore, since I installed the proprietary driver and Xfce on Mint Lisa comes with mouse cursors from KDE, the selected mouse cursors for Xfce are ignored. Ubuntus Studio Oneiric and Arch Linux are running Xfce only. Suse 11.2 and Edubuntu Maverick still run GNOME2. - Ralf

I started the translation of Qtractor a month ago and due to issues such as pulseaudio and the dropped nv driver (and some other issues) I can't contribute, continue translating, but just fix issues, hence my only contribution could be to set up machines for users who are willing to learn, but are unable to learn all things at the same time, for their first Linux install. At least distros shouldn't do a default install with 3D effects enabled DEs and than install the nouveau driver by default if a NVIDIA graphics was detected. A 2D desktop and the vesa driver would allow beginners to get their first install working OOTB and to learn how to maintain their own machine. Btw. some distros don't install bryltty by default. Nowadays only 3D DEs count. That's a step in the wrong direction. Regards, Ralf

Using SB AWE64 MIDI interfaces

by feloy2＠free.fr

Hello everybody, I'm trying to install a soundblaster AWE64 (chipset CT5880), with a joystick port to connect external MIDI devices. I can get audio output, but I also would like to: - upload soundfonts to this chip, - use MIDI interfaces from this card, to play MIDI files through this chipset instead of using Timidity, and to communicate with external MIDI devices I'm trying to do this in Ubuntu 10.04 (kernel 2.6.32) Please note that I know quite well how Linux works in general, but I have very small knowledge in computer assisted music (I'm trying to install this for my wife, who would like to use rosegarden to write music).
