[ANN] IR: LV2 convolution reverb 1.2.2 & 1.3.2

by Tom Szilagyi

IR: LV2 Convolution Reverb http://factorial.hu/plugins/lv2/ir IR is a no-latency/low-latency, realtime, high performance signal convolver plugin especially for creating reverb effects. This is a much overdue maintenance release with two versions under the dual versioning scheme: 1.2.2 in the 1.2.x branch and 1.3.2 in the 1.3.x branch. From the ChangeLog: Version 1.2.2 and 1.3.2 - 2012.07.02 18:05 CEST This pair of versions contains the migration to use zita-convolver-3.x.x in place of zita-convolver-2.0.0. This change guarantees that there are no data overruns while running the plugin non-realtime (freewheeling / Ardour export). NOTE: please read the plugin's webpage if you are confused about the dual versioning of IR (1.2.x vs 1.3.x). Please see the website for further information regarding versions, installation, caveats & usage. Thanks, Tom

[ANN] MusE 2.0 released

by Robert Jonsson

Hello everybody! Finally it has happened, nearly two years from the last stable release we are ready to present to you the final MusE 2.0 version. A lot has happened and changed, still the migration from 1.1 to 2.0 should be quite easy and definitely worth it. The big changes since 1.1 are as follows: * Moved to qt4, this affects the visuals and potentially improved portability * Graphical automation in the arranger * A new score editor * MusE now defaults to using midi through Jack, -A enables native alsa support * New style MDI gui with a bunch of configuration options to satisfy all tastes * Redone midi editing tool dialogs with lots of new functionality * Lots and lots and lots of internal small and big changes to improve stability, speed and functionality * PSIIF support (support for: probably something important I forgot) A much condensed list of changes since the last beta are as follows: - Sync fix: MusE now records tempo changes from externally clocked midi. - Finally! Audio controller playback has smooooth frame resolution even with large audio buffers. - Feature: Midi control of audio paramters. - Lots of automation improvements - Switched to use JACK midi - Added: -A switch: "Force inclusion of ALSA midi even if using Jack". - Lots of leaks removed - Added colorhints to iR and oR routing buttons - Templates: File dialog: Lots of changes - Lots of widget focus fixes - Allow loading of DSSI synths in LADSPA browser. - Midi editors: Added "Delta Mode" button to Note Info toolbar. The full changelog is available at: http://lmuse.svn.sourceforge.net/viewvc/lmuse/tags/muse_2_0/ChangeLog?revis… Find the download at: https://sourceforge.net/projects/lmuse/files/ Also a big thanks to everybody who has helped translate, find and fix bugs and otherwise been lending a helpful hand! Happy creating/recording/playing/arranging with MusE! The MusE Team ps. And stay tuned for the inevitable 2.0.1 release ;) ds. -------------------------- MusE 2.0rc2 Hello everybody and a happy new year! The final release is now in sight, here is one (hopefully) final release candidate, rc2. Quite a bit of polish has been done in the gui and some under the hood fixes for various audio and midi data handling. Crunched list of improvements: - New super-glue feature - Global Cut: Fixed crashes with markers. Re-did marker section in structure.cpp:adjustGlobalLists(). - Fixed drag and drop cloning parts - bad reference count in PartCanvas::moveItem() - File Open dialog: Start with song data and configuration. - New 'Duplicate tracks' Edit action, and dialog. Post-cleanups. TODO: Copy plugins, fix copying parts - Audio strip prefader now controls audio. - Fixed: Annoying ladspa browser issues. Leak: Dialog was not destroyed. Sorting. Save complete state - Fixed long-time graphics corruption issue: Large areas of desktop erased to background. - New: Midi routing matrix! No more clumsy routing menu items. Currently for Midi Track iR and Audio Input iR solo routes - Improved: Midi ports list now fills automatically at start - List only writeable ports in track list output port column and midi track info combo box. - Jack midi devices now save an additional required rwFlags xml tag. - Midi ports dialog: Auto dis/connect the stated default channels when selecting a device. - Complete Spanish translation from Cristian Ramos - Improved: Project save dialog: Now has quick save as Template. Separate project/result paths shown. Editable project folder. - Added: Project directory in global settings dialog. - Changed: In File Dialog, 'User' initial prepend path changed to muse ./config path. So user files + templates are shown. - Fixed: Template directory changed from /home/templates to muse config directory. Support for old files included. - Fixed: DSSI synth audio inputs. This means dssi vocoders, samplers etc. should work now - Re-write: Fixed audio mixing, meter processing. Audio, and meters, for all mono <-> stereo route combinations work sensibly now. - Window titles of ladspa and dssi plugins now have track name prefix to help identify them. - Added "Unused Devices" menu to the arranger's port popupmenu for rapid device selection The full changelog is available at: http://lmuse.svn.sourceforge.net/viewvc/lmuse/branches/release_2_0/ChangeLo… Find the download at: https://sourceforge.net/projects/lmuse/files/ Please report any findings either to one of the following Mailinglists: http://muse-sequencer.org/index.php/Muse_ml The bug tracker at sourceforge: http://sourceforge.net/tracker/?group_id=93414 The forum: http://sourceforge.net/apps/phpbb/lmuse/ Have fun! The MusE Team -------------------------------------------------------------- MusE 2.0rc1 Hello everybody, Getting close to the new year, better hurry with the christmas shopping! Not that this has anything to do with new MusE releases even though one could consider it a christmas present. :) Since the last beta relentless bugfixing has taken place and lots and lots of feature improvements in preparation for releasing 2.0 sometime soon (tm). Crunched list of improvements: - added sane configuration defaults to muse - added MDI-like and borland-like user interface - improved copy paste with paste dialog - Lots of new internal namespaces e.g. MusEArranger and MusEMixer - gui widgets with new look, especially in mixer - score editor improvements - reworked midi tools - Popup menus: If stay-open mode, space triggers item and double-click simulates return - Changed midi track info patch popup behaviour. Now stays open for auditioning patches - Changed editor 'ctrl' controller popups. Split instrument/other (+ common controls!) + show ctrl numbers - Changed mouse wheel behaviour in graphical editors except the score editor - Added dialog to remove unused wave files - Changed default imported midi song type to GM + lots more bugs squashed, improvements, code reorganizations The full changelog is available at: http://lmuse.svn.sourceforge.net/viewvc/lmuse/branches/release_2_0/ChangeLo… Find the download at: https://sourceforge.net/projects/lmuse/files/ Have fun!

The alpha indicates this is an early version so it's mainly - a teaser to spread the word. - an early adopters build. - to welcome developers who want to port MusE to other platforms. MusE has now been completely ported to the Qt4 architecture and we (mainly Tim and Orcan) are busy to make it even better than before, lots of gui stuff being reworked. MusE now also sports a new version of the DeicsOnze, DX11 emulating softsynth, up from version 0.2 to 1.0. The homepage has received a new look that we hope will give a better indication of what MusE is and does. Do visit http://muse-sequencer.org.

Lisalo 1.0 - LinuxSampler Loader (Working File for Sonatina Symphonic Orchestra included)

by Nils

This is the Release of Lisalo 1.0 Grab it here, no installing required: git clone git://github.com/nilsgey/Lisalo.git Lisalo - Linux Sampler Loader Linux Sampler Loader is a command line program that loads entire directories of sample files or takes instructions from a meta .lsl file with relative paths to samples. This program exists because you can't share linuxsampler lscp files or even move files around on your own disk. Lscp files only work with absolute paths and are too low level anyway. Now you can quickly and easily load sampled instruments without even starting a GUI. The lsl files are very simple, see example.lsl, and can be shipped around with your sfz sample package like the Sonatina Symphonic Orchestra (lsl file already included in this release) Version 1.0 Licensed under GPLv3 by Nils Gey, June 2012 Only dependencies are Python and Linuxsampler. https://github.com/nilsgey/Lisalo info(a)laborejo.org irc.freenode.org #laborejo

Look for volunteers for Free Music Instrument Tuner

by Gilles Degottex

Hi all, I created this software in 2004, but I can't develop it anymore, maintain it or even answer the mails I receive about it. http://home.gna.org/fmit http://gna.org/projects/fmit I'm therefore looking for volunteer(s) to recover the project: manage it, maintain it, develop it if motivated, etc. The current state of the software is fairly good, I think. It has been updated to Qt4 last year. I think it's quite stable because most of the mails I receive from users are about how to select the recording channel in their OS mixer ... FMIT is accessible from Ubuntu repositories (universe) and was accessible under Fedora but they removed it since I can't maintain it anymore. Please look at the website for more details and screenshots. Besides the fact that I want it to stay open-source, I don't have particular wish about its future (hmmm, stay simple and expandable maybe). So, if someone is interested, please contact me. All the best, Gilles -- FORTH - ICS Vasilika Vouton, P.O. Box 1385 GR 71110 Heraklion, Crete, Greece Mobile: +30 6942 207403 Work: +30 2810 391580

CueFrog.pd: theatre cue player framework initial release

by Jörn Nettingsmeier

hi everyone! thanks to the excellent pd documentation out there and lots of hand holding by friendly pd gurus on this list and elsewhere, here's my humble take at creating a theatre cue player with pd that does what i need... all the heavy lifting is done by august black's excellent readanysf~, thanks for making this tool available! CueFrog is designed to be multi-instance capable, so you can create as many decks as your machine can handle, and makes use of lots of send/receive ports to simulate some kind of object-oriented encapsulation stuff, based on my (limited) understanding of a model/view/controller paradigm. grab it: http://stackingdwarves.net/public_stuff/software/CueFrog/CueFrog-0.0.2.tar.… it's documented, so you should get it going in no time. i'm sure there are many quirks there, and i found out it's very easy to create race conditions in pd, so no warranties :) comments and suggestions for improvements are most welcome. i have a vbap-based panning automation in the works (which has already been used live at a theatre festival), but the code is in oh-my-good-tomorrow-is-dress-rehearsal shape, so forgive me for withholding it another month or so. and before you ask: frogs are cute. and when the director makes me jump, i need tools that jump along :-D best, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net

ALSA multi plugin and JACK xrun callbacks

by bart＠magnetophon.nl

Hi Everybody, My name is Bart, this is my first post here, though some have met me on IRC. Thanks for making Linux audio what it is! I started using Linux in 2004 with DeMuDi, and have never looked back. I'm trying to get my pcm_multi to work without with jackd. Some of you seem to have got this down, with or without "ghost xruns". Jörn seems to imply in the quoted thread that tschack is the answer, but it gives me the most xruns of all jack implementations. Who has got this working? Who want to help me get to the bottom of this? Google has been a great help so far, but I'm not sure what to try or what to google anymore. :( So far I've tried: *jackdmp1.9.9 *jackd1 (1:0.121.3+20120418git75e3e20b-2) *http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.121.3.tar.gz *https://github.com/adiknoth/tschack.git All tested with the 3 kernels mentioned below. The nedko jack with the avlinux kernel sometimes goes without xruns for quite a long while, but sometimes gives lots of them. I haven't found the pattern behind it yet. My system is fully tuned, according to realTimeConfigQuickScan.pl the only exceptions: cat: /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor: No such file or directory Checking CPU Governors... CPU 0: '' CPU 1: '' CPU 2: '' CPU 3: '' - not good I assume this is because my cpu's are running full speed. Kernel with Real-Time Preemption... not found - not good Checking if kernel system timer is set to 1000 hz... not found - not good But I'm running 3.2.0-2-rt-686-pae #1 SMP PREEMPT RT Fri Jun 1 20:28:43 UTC 2012 i686 GNU/Linux. I've also tried linux-image-3.0.32-avl-8 from avlinux, debian 3.2.0-2 vanilla. Here is my .asoundrc: https://github.com/StudioDotfiles/DotRepo/blob/master/asoundrc I'm runing jack like this: jackd -d alsa -r 44100 -p 4096 -d rme9636_64 The two rme9636 soundcards are on their own irq's, with priorities just below the timers. Jack with just one card works like a charm. Is there any other info needed? Thanks a lot, Bart.

Aborted the cpu is not maxed out, afaics. tschack handles this scenario just fine, and it doesn't spew error messages on the console. if i monitor it in qjackctl, the xrun count increases at the usual rate, though. btw: qjackctl becomes a major cpu burden in this pathological case. lookes like it's the error messages. i've seen it at up to 40% of one core.

[ANN] Qtractor 0.5.5 - The Foxtrot Uniform swings out!

by Rui Capela

Here it goes. Mostly a LV2 1.0.0 compliance release with some fixes from the stash and fewer candies from the jar. On the darker/brighter side (your choice) there's news on the LV2 atom(ic) fall-out now being officially over. A new dawn has commenced, quite as every day follows every night may I add. Dang! I'd better stop right here and save you all from that boring trivialities. Let's go with the plain, interesting facts: Qtractor 0.5.5 (foxtrot uniform) swings out! Release highlights: * LV2 Atom/MIDI support (NEW) * LV2 Worker/Schedule support (NEW) * LV2 Presets support (NEW) * LV2 Time/position support (NEW) * LV2 Programs/instrument support (NEW) * MIDI plugin event timing on tempo changes (FIX) * Loop-recording/takes audio sync (FIX) * Quick start guide and user manual (NEW) * Russian and Italian translations (NEW) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.5.tar.gz - source package (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.5-4.rncbc.suse121.sr… - binary packages (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.5-4.rncbc.suse121.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.5-4.rncbc.suse121.x8… - brand new (quick start guide &) user manual: http://downloads.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Auto-monitored MIDI tracks were missing their pass-through to their respective MIDI output bus plugin chains, now fixed and letting any multi-timbral instrument plugin to get a peek from auto-monitoring. - New user option/preference to whether to open a plugin's editor (GUI) by default, when available (cf. View/Options.../Plugins/Editor). - Clicking and/or dragging for rubber-band selection on main track-view canvas doesn't change the edit-head and -tail positions anymore. - Backward and Forward transport commands now have an additional stop at first clip start point. - LV2 Atom/MIDI buffering support is finally entering the scene; LV2 Worker/Schedule support is also included in a bold attempt to convey non-MIDI event transfers between plugin and its UI. - MIDI Clip editor (aka. piano-roll) and MIDI Tools fix: avoid note-on events of zero velocity, which conventionally equates to a dangling note-off event and dropped into oblivion sooner or later. There's no more need for Shift/Ctrl keyboard modifier to change in one single step all the MIDI events that are currently selected (now consistent with drag-move). - LV2 Presets support now entering effective operational status; a new local option has been added (cf. View/Options.../Plugins/Paths/LV2 Presets directory; default is ~/.lv2). - Dropped XInitThreads() head call as it was never useful but on those early days of JUCE VST plugins. - Italian (it) translation added (by Massimo Callegari, thanks). - Clip fade-in/out dragging now follows snap-to-beat setting. - Late modern eye-candy indulgence: alternate shaded stripes, on every other bar as in a "zebra" background option for the main tracks and MIDI clip editor views (cf. View/Snap/Zebra). - LV2 Time/position information is now being supported through special designated plugin input ports (after suggestion by Filipe Coelho aka. falktx). Additionally, the time/position information report has been corrected and complemented for VST plugins. - Audio vs. MIDI time drift correction has been slightly improved against rogue tempo changes across looping cycles. - Honor tempo/timing on MIDI instrument plugins. Happy regression fix on getting MIDI note-offs at looping ends back in business; all the necessary bumming for MIDI plugins to play nice in face of tempo changes and whenever playback is started from anywhere but the beginning of the time-line (ie. frame zero); thanks to rvega aka. Rafael Vega, for the heads-up). - Audio clip wave-forms were being displayed in inverted phase (ie. upside-down) all this time ever since day one. What a shame! - LV2 Programs interface is getting initial experimental status, to let LV2 instrument plugins get on par with the DSSI and VST crowd for MIDI bank/program instrument inventory and selection support (a sidetrack complot with Filipe Coelho aka. falktx, thanks:). - Dropped the old but entirely useless LV2 URI-unmap feature, now being superseded by official LV2 URID (un)mapper. - Russian (ru) translation added (by Alexandre Prokoudine, thanks). - SLV2 deprecation process started, effective now at configure time. - Added include <unistd.h> to shut up gcc 4.7 build failures (patch by Alessio Treglia, closing bug #3514794). - Another approach avoiding recursive observer widget updates. Also applies to mixer, monitor and track state buttons. - Update to latest LV2 state extension (by David Robillard, thanks). - Loop-recording/take number displayed on clip title, respectively. - Make(ing) -jN parallel builds now available for the masses. - A one buffer period slack on audio engine's loop turn-around logic might just have fixed an illusive report on loop-recording/takes going progressively out-of-sync, most notably when recording under large audio buffer period sizes (>= 1024 frames/buffer). - Editing MIDI while playback is rolling, doesn't mute the track any more, adding a point to the live editing experience. - Finer granularity for direct access parameter mouse wheel changes. - Dropped a dumb optimization for short full-cached multiple linked/ref-counted audio clips which were incidentally out-of-sync after rewind/backward playback. Once again and uncertain to be the last take on this, got fixed (probably related to some oddity reported by Louigi Verona, thanks). Enjoy! -- rncbc aka. Rui Nuno Capela

LV2 Atom Sequence timestamps

by Jeremy Salwen

Hi All, >From what I can tell, it looks like the LV2 Atom Sequence specification allows you to send events with arbitrary units for the timestamp. I have a few questions about this: 1. How are we to know whether a particular unit uses the *double* field in the timestamp union, or the *uint64_t *field in the timestamp union. 2. The specification says "The unit field is either a URID that described an appropriate time stamp type, or may be 0 where a default stamp type is known." In what circumstances would the timestamp be known? When can I expect to see a zero in that field? 3. Are the timestamps absolute times? Or relative to the previous event? Or relative to the start of the audio chunk? Does it depend on the units used? 4. Why does the documentation<http://lv2plug.in/doc/html/structLV2__Atom__Sequence__Body.html>show |FRAMES |SUBFRMS| as the timestamp field? From what I can tell, there is no unit which includes frames and subframes subdivided that way, and the sampler example </> just uses the full 64 bits as a frames field. Is this just a relic from the old event port documentation? (the diagram seems familiar). 5. How are hosts/plugins supposed to deal with the multiplicity of units? For example, suppose I'm a plugin or host that wants to receive MIDI data. How am I supposed to know what timestamp unit to expect? Is there a facility for converting between different units automatically? The only extra information required to convert between any two time units would be the bpm and sample rate. It would be rather annoying to have to implement a bunch of unit conversion code in every host/plugin you write in order to make sure it can handle any unit which is tossed at it. Thanks, Jeremy
