The first unified LV2 release, LV2 1.0.0, is out. This release merges the previous lv2core package with all the official extension packages, as well as example plugins, lv2specgen, and additional data. From a developer point of view, the biggest change is that all LV2 API headers can be used by simply checking for the single pkg-config package "lv2" (for compatibility the previous "lv2core" package is still installed). Implementations are encouraged to abandon the "copy paste headers" practice and depend on this package instead. With this release, several new extensions have become stable that together greatly increase the power of LV2: atom, log, parameters, patch, port-groups, port-props, resize-port, state, time, worker.

QMidiArp-0.5.2 released

by Frank Kober

Hi, QMidiArp 0.5.2 has just seen the light of the day. It brings mainly two improvements. One is a comeback, that of tempo changes on the fly, and that now includes also tempo changes of a potential Jack Transport master. Also the Jack Transport starting position is finally taken into account, so that QMidiArp should be in sync also when starting the transport master not at zero. The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen! Note that for compiling in NSM support you will now need liblo as dependency. Enjoy, and enjoy LAC in Graz this year Frank ________________________________ QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. Everything is on http://qmidiarp.sourceforge.net qmidiarp-0.5.2 (2013-05-09) New Features o Tempo changes are again possible while running, both manually or by a Jack Transport Master o Jack Transport position is now taken into account when starting, QMidiArp used to start always at zero o Muting and sequencer parameter changes can be deferred to pattern end using a new toolbutton o Modules in the Global Storage window have mute/defer buttons o Global Storage location switches can be set to affect only the pattern o Non Session Manager support with "switch" capability (thanks to Roy Vegard Ovesen) General Changes o NSM support requires liblo development headers (liblo-dev package)

ANN: New Pd-L2Ork x86_64 and Raspberry Pi release now available together with comprehensive how-to

by Ivica Ico Bukvic

It is my great pleasure to announce immediate availability of the latest Pd-L2Ork, its K12 module, as well as the inaugural official version of Pd-L2Ork for the Raspberry Pi platform. The new release is accompanied by a comprehensive documentation on how to connect RPi to the computer as well as run and configure Pd-L2Ork (and its K12 module) for operation on RPi. In addition, as part of this release, the regular Pd-L2Ork install instructions have been also streamlined to make them easier to navigate. Special thanks to NewBlankets Inc. for the Satchmo SuitSup Award that made our RPi hacking efforts possible! For more info visit: http://l2ork.music.vt.edu/main/?page_id=56 (x86_64 version with updated how-to) http://l2ork.music.vt.edu/main/?page_id=2288 (Raspberry Pi version download and how-to) Changelog highlights: *Fixed bug http://sourceforge.net/tracker/index.php?func=detail&aid=2457992&group_id=55 736&atid=478070; hopefully also fixed incorrectly reported hit/selection boxes for nested structs (like the one reported in the previous bug report) *added ability for preset_hub to write/read presets or entire scenes from files. Improved documentation to reflect new additions and to improve existing. *added multi-connect option with 5 different modes: 1. shift-click manual multi-connect 2. two selected objects multiple outlets to multiple inlets 3. two or more selected objects connecting to one unselected one 4. one unselected connecting to multiple selected ones 5. multiple selected ones connecting to one's multiple inlets OR the other way around (determined on whichever mode gives more valid connections) Option 1 requires use of shift. Other options are based on what is selected at the time of making the first connection (others are automatically created based on conditions). Later consider adding special undo that undos all connections in one step, rather than multiple steps. For more info, please see Jonathan's recent email on the pd-list: http://lists.puredata.info/pipermail/pd-list/2013-05/102871.html *added ability for gop to intelligently detect when iemgui objects fit (or don't) inside gop window. the same also applies to dynamic changes to iemgui properties (size, font, label, delta, position, etc.) *selection box makes patch scroll when reaching patch window edge *Added support for multiline comments (with some help from Taylor O'Connor and Jean-Philippe Ouellet). *disis_wiimote 1.0.4 *added raspbian compile option *improved logic for freeing rtext that alleviates memory leak but also does not crash abstractions and gop objects (there are still memory leaks apparent in l2ork_output~ external which may be linked to individual objects having incomplete free functions). See http://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid= 478070 for more info *Fixed segfault bugs with ascseq and ascwave externals *fixed memory leak (see https://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid =478070) *bug fix http://sourceforge.net/tracker/?func=detail&aid=3605973&group_id=55736&atid= 478072 Complete changelog (without the highlights): *backported tcl updates to properly support updated pddplink *fixed segfault when closing array window/subpatch due to lack of checking of valid resize/move hook pointers *added example files for the expanded preset_hub documentation *fixed accelerated displace bug where nested structs did not get properly tagged/selected *fixed erroneous meta file generation script *numerous bug-fixes for mouse down/up and key press combos (e.g. shift-clicks for multiconnect and dragging within an object) *added accelerated displace to pddplink *Made pddplink color match pd-l2ork *cosmetic improvements to Scope~ and coll *improved nlet highlighting (integrated it into glist), fixed bug with multiselect with mixed objects (accelerated and legacy) *improved scrollbar color selection *reintroduced cleaned up version of tooltip arrows *cord inspector is hidden during font scaling *improved font scaling and made cord inspector appearance consistent with tooltips *improved font scaling for size 24 *fixed consistency check error for magicGlass (regression) *fixed k12 shortcuts where secondary menu did not invoke k12 mode *minor fixes to the K12 library *added automatic resize of arrays when adding/removing points via ctrl+click, fixed a bug where array is not properly redrawn after a new point is created *made sure that properties windows associated with a patcher that is being closed are also closed at that time. *added an article to the NaN error report text *improved pow logic to accept negative numbers and deal correctly with NaN situations *added proper getrect support for comment objects *made drag scrolling less cpu hungry and easier to control *cords in front after iemgui properties apply *more scrolling improvements *lowered rate of getscroll when pasting to minimize cpu overhead *fixed random shifting of scroll when duplicating an object *proper fix for the crash when closing one of the many concurrently open root patches *automated installer clean-up for flext *remaining clean-up and flext integration in the intel/rpi build process *dependencies update *updated postlude *improved shortcuts so that pd-l2ork auto-creates midi ports on start-up *support for flext and auto-building of fluid~ and disis_munger~ *fixed bug where select all did not work with Console window focused *fixed regression where windows were not properly raised *improved window placement logic of new pd windows *improvements to disis_wiimote to provide unsuccessful attempt at connecting with an explicit 0 from the connect outlet (version bump to 1.0.4) *fixed stray bugs that were introduced with drawsymbol and resizable fonts and made drawnumber font resizable as well *made drawsymbol a distinct object that properly opens its help file and also supports resizable fonts *added input highlighting ability like that of iemgui's number2 to gatom class *fixed text not getting displaced properly while dragging a scalar (due to incomplete accelerated displace implementation) *fixed segfault due to delayed freeing of bindlists (necessary to prevent a segfault for dynamically changed sends/receives) *improvements to the incremental install script *new/improved icons *fixed typo for the new -r option (RPi build) *Improvements to the disconnection logic to the disis_wiimote *made shortcuts more flexible in terms of startup (not forcing JACK, which will help on setups that don't want/need JACK backend), as well as providing intelligent menu shortcuts for ALSA and JACK *made disis_wiimote statically linked so that new installs do not require install of the custom cwiid library that potentially clashes with other deb-based versions. *fixed regression from IOhannes' proposed fix (see e7acc4796b655100b650f898bb10687fb9f7355d commit) that affects propagation of scalar pointers through the trigger object. Use scalar-help.pd to test. *hopefully improved libglew support due to unfortunately named libs that limit their flexible rollout across different versions of Ubuntu (and likely other distros as well) *hopefully fixed stray iemgui dialog error when returning from the custom color selection dialog *removed unnecessary canvas_vis consistency check *fixed erroneous undo behavior after cutting two objects in a row *updated moonlib to the latest version and made changes to mknob.c to support accelerated displacing with tag *fixed midi dialogs *added ability for select object to recognize bang events *improved IO Error button on/off handling *refinements to the memory leak fix that avoid tripping consistency check in the findrtext *further refined trigger mechanism to offer ability to convert anything->symbol *implemented improvement for empty lists as suggested by IOhannes http://lists.puredata.info/pipermail/pd-list/2013-02/101518.html *fixed remaining memory leaks when instantiating/deleting abstractions (see previous commit). *minor adjustments to the binary script-based installer for the pd~ external support. *fixed bug where pd-l2ork symlink for pd~ external did not get installed Best wishes, Ivica Ico Bukvic, D.M.A. Composition, Music Technology Director, DISIS Interactive Sound & Intermedia Studio Director, L2Ork Linux Laptop Orchestra Head, ICAT IMPACT Studio Virginia Tech Dept. of Music - 0240 Blacksburg, VA 24061 (540) 231-6139 (540) 231-5034 (fax) ico(a)vt.edu http://www.music.vt.edu/faculty/bukvic/

vst-bridge 0.1

by Alexandre Bique

Hi, I'm proud to announce vst-bridge 0.1. This is a bridge to run Windows VST plugins (both 32 and 64 bits) with Linux VST hosts. = How to use it? = Let's suppose that you have installed vst-bridge in ~/local/ and you have a windows VST installed in ~/.wine/drive_c/VST/Synth1/Synth1.dll First you have to create a directory for your bridges: $ mkdir ~/.vst-bridges Then you can create your first bridge: $ ~/local/bin/vst-bridge-maker ~/.wine/drive_c/VST/Synth1/Synth1.dll ~/.vst-bridges/Synth1.so Now edit ~/.bashrc and add $HOME/.vst-bridges/ to VST_PATH. Mine looks like: export VST_PATH=/usr/lib/vst/:$HOME/.vst-bridges/ Then you can start your favorite DAW, ask him to scan plugins again and enjoy! = Architecture = A typical installation looks like: /home/abique/local/ /home/abique/local/bin /home/abique/local/bin/vst-bridge-maker /home/abique/local/lib /home/abique/local/lib/vst-bridge /home/abique/local/lib/vst-bridge/vst-bridge-plugin-tpl.so /home/abique/local/lib/vst-bridge/vst-bridge-host-32.exe /home/abique/local/lib/vst-bridge/vst-bridge-host-32.exe.so /home/abique/local/lib/vst-bridge/vst-bridge-host-64.exe /home/abique/local/lib/vst-bridge/vst-bridge-host-64.exe.so vst-bridge.so is a Linux VST plugin which has space reserved for the windows plugin path. vst-bridge-maker creates a dedicated <plugin>.so for a single Windows VST plugin by copying vst-bridge-plugin-tpl.so and updating the path to the Windows VST and the path to the corresponding host (32 bits or 64 bits). vst-bridge-host-(32|64).exe hosts a Windows VST and communicates with <plugin>.so. <plugin>.so spawns a new wine process vst-bridge-host-(32|64).exe and passes the path to the Windows VST plugin. You can find the source code released under the MIT license at https://github.com/abique/vst-bridge You can also find binary tarball at http://88.191.147.34:4242/vst-bridge/vst-bridge-0.1.tar.gz It has been reported to work with: Synth1, ReFx Nexus, u-he Diva, ABL2, epicVerb, NastyDLAmkII. I had issues with : Oatmeals, NI Reaktor. Thanks for your attention. I hope you'll enjoy it. -- Alexandre Bique
