Foo YC-20 1.2.1 released

by Sampo Savolainen

Hi, Denormal protection for the LV2 and VST plugins was left out by mistake from the 1.2.0 release. Version 1.2.1 fixes this. There is no need to update the OS X version as the Jack clients were not modified.

Linux Audio Monthly Round-Up #6 - January 2011

by Jeremy Jongepier

Dear all, The holiday season is over and I actually took advantage of it by not working on this month's round-up but by making music. With the help of Leigh Dyer's outstanding seq24 tutorials I'm trying to master seq24 and so far I'm really enthusiastic about this sequencer. I've started remixing an older track of mine and seq24 has already proven itself a very valuable tool. But I did read up on relevant mailinglists and forums to keep in pace with the developments in Linux Audio Land. And December did yield some interesting topics, like the RT_GROUP_SCHED option (cgroups) discussion on the Jack-Devel mailinglist and the refutation that CPU frequency scaling has no use for low-latency real-time audio, and then there was the sheer amount of music made with Linux of course! Best, Jeremy PS. Thanks to the people from LinuxMAO, without them I'd miss out on a lot of developments, releases and other non-trivial events worth mentioning!

Foo YC-20 1.2.0 released

by Sampo Savolainen

Hi, I am proud to introduce a new version of Foo YC-20, the Yamaha YC-20 software synthesizer. The main udpates in version 1.2.0 are: - LV2 plugin - VSTi plugin (and standalone Jack client) for Windows - OS X build (standalone Jack client) - Improved volume control curve - Fixed bug with 4' drawbar bleed - More subtle hover highlights - Switch GUI to use GTK directly without GTKmm It is worth noting that the plugins allow finer control of the drawbar positions than the standalone GUI offers. Big thanks to Robin Gareus for the work on the OS X build! Source tarball: http://foo-yc20.googlecode.com/files/foo-yc20-1.2.0.tar.bz2 Windows (VSTi and Jack client): http://foo-yc20.googlecode.com/files/foo-yc20-1.2.0.zip OS X (Jack client): http://foo-yc20.googlecode.com/files/foo-yc20-1.2.0.dmg Website: http://code.google.com/p/foo-yc20/ Screenshot: http://foo-yc20.googlecode.com/svn/trunk/graphics/screenshot.png --- The YC-20 is a divide-down combo organ designed in the late 60's. This emulation faithfully copies the sound, features and flaws of the original organ. Main features of this synthesizer: * 61 keys * Two main voice sections * Switchable bass section * No polyphony restrictions * A realism control to add flaws found in the real organ Flaws: * Takes quite a bit of CPU power * No touch vibrato The emulation is written in Faust and uses Jack for audio and MIDI. All controls of the synthesizer can be controlled with MIDI. There is an undocumented "easter egg". Any command line argument given to the program will be used as the configuration file name. The state of the organ controls are read from the file and the file will be overwritten with the current setup when the synthesizer is shut down. More information about the real organ can be found at: http://www.combo-organ.com/Yamaha/yamaha.htm#YC-20 Sampo Savolainen

Qtractor 0.4.8 - The Fiery Demigoddess released!

by Rui Nuno Capela

howdy so i lied, bluffed all the way, so what? should I be sorry? what you'd expect from this one self-called ber-procrastinator ? and then there's hope. alas, not the messiah, rather my development drive at my own pace. believe it or not, it is on-going and it will sure happen real soon ;) no sweat. The whole automation prophecy will be realized and delivered. yes, TYOQA just failed, slipped a bit. it doesn't mean it was abandoned though or, uh, procrastinated... well, it's only a happy new year after all:) the road to automation is being already being paved and walked although, i must say, it is no yellow-bricked one. the drive has begun. definitely, 2011 will be TYOQA (aha, read that again with a bold tee:)! more than automation, which infrastructure is already lurking in there, trus me, all work is being carried out at the backyard for the time being. blossoms might just pop out this spring ;) one thing i may wish to leave sound and clear: it is very likely that, in the very near future, that there will be some dot-release before the all-mighty-one release, whatever. now that the surprise-effect is gone, the long overdue and hailed beta release cycle that will present you and carve its deeds on stone with the dynamic-curves and automation features et al., will be nothing less nor before the coming version numbered as the 0.5.x scheme. then, and only then, the current alpha-cycle will be concluded. of course, that will be also the time for translations to be called in. just be a little more patient :) and then i lied a second time, when said those parodied f&d release code-names were exhausted. thanks to a lengthy but intermittent fall/winter-of-coding period, i had the chance to wake up one morning with the imagination score in its lowest end and roar an inner WTH! as they say around here, there's no second without a third. so another lie is there waiting to be told. or is it not? there, one would say: time will tell... Release highlights: * Archive/Zip session file bundle (save as... .qtz) (NEW) * Mixer MIDI controller mapping/learn (NEW) * LV2 GTK UI support (NEW) * LV2 Persist extension support (NEW) * MIDI Tools on main track/clips view(NEW) * Floating tool-tips while dragging/moving/pasting (NEW) * Rescale and Timeshift MIDI tools (NEW) * MIDI Quantize percentage (NEW) * Track range selection (NEW) * Audio insert send, wet/dry controls (NEW) * Audio clip pitch-shifting (FIX) * Metronome dedicated outputs related crash (FIX) * Stop transport tool/button action (NEW) * Mouse-wheel zooming (NEW) and a few more assorted features and fixes--see below the complete (boring) change-log for gruesome details. Nuff said. Qtractor 0.4.8 (fiery demigoddess) released! Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.8.tar.gz - source package (openSUSE 11.3): http://downloads.sourceforge.net/qtractor/qtractor-0.4.8-2.rncbc.suse113.sr… - binary packages (openSUSE 11.3): http://downloads.sourceforge.net/qtractor/qtractor-0.4.8-2.rncbc.suse113.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.8-2.rncbc.suse113.x8… - user manual (archeologically dated): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, openosource software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - MIDI controller mapping/learn is now possible on all mixer controls (monitor, gain, panning, record, mute, solo). - An internal rewrite (aka. refactoring) have been carried out, making sure that all track state action buttons (R, M, S) are now all under the observer pattern umbrella. - Single track range selection is now available on main menu (Edit/Select/Track Range; default keyboard shortcut: Ctrl+Shift+R); additionally to vertical range and horizontal track actions (Edit/Select/Range, Track) all these operations can now toggle over the previous selection. - Direct clip selection from Files list item has been brute-forcefully implemented (after being challenged by Jiri Prochaszka aka Anchakor:). - Files tree widget sticky "New Group" item fixed. - A new menu option has been added (View/Tool Tips) to show/hide a floating tool-tip while dragging, moving, resizing or pasting selected clips or events over the main tracks view and MIDI clip editor (piano-roll) respectively, displaying current target position and status. - Attempt to reset audio/MIDI time drift compensator on every engine start and loop turnaround. - Moving the punch-out marker over the main track time ruler was failing to shrink the punch-in/out range, now it does (not). - MIDI clip tools (quantize, transpose, normalize, randomize, resize, rescale and the new timeshift) are now all accessible from the main tracks view (Edit/Clip/Tools menu) and apply to all events on current selected clip(s). - LV2 Persist extension support is being introduced. - A new timeshift MIDI tool has been added, after an awesome patch by Jiri Prochaszka aka Anchakor; applies to selected events between edit markers, distorting their time and duration (optionally), either slowing down and accelerating, based on a given parameter P value. - Audio clip/buffer pitch-shifting fixes with regard to latency correction due on the RubberBand library one-pass (real-time) processing mode. - New Send Gain and Dry/Wet control parameters have been implemented for audio Inserts pseudo-plugins. - MIDI channel/master volume enqueued events are now affected by the current track/bus volume (0-100%). - Prevent old rounding error when resetting to plugin parameter default value with the mouse middle-button click while hovering a slider widget (observer). - A quantize percentage has been added to MIDI clip editor quantize tool (Tool/Quantize...) for time and duration quantization (0% for none; 100% for full regular quantization). - Metronome bus/ports are now created at engine start and not when user switches it on anymore. - Make sure all audio clip buffers are in sync upon smooth-ramping going off and playback is rolling. - Copy-pasting across controller event types is now possible on the MIDI clip editor (aka piano-roll). - Finally indulged, the genuine transport stop button makes its appearance on main toolbar and menu. - Main tracks grid visibility option (View/Snap/Grid). - Yet another off-by-one (frame) audio buffer bug got squashed away: rare symptom was that some audio clips were being left dead silent right after playback of their first looping period. - Plugin parameter name/label now a proper attribute of its respective MIDI Controller observer instance, allowing to be shown on dialog title (MIDI learn). - Default session file format saved on JACK session demand is now the bundle archive/zip one (.qtz). - Plugin selection dialog now shows whether a plugin features its own editor (GUI) and/or external state configuration (EXT). - Help/Shortcuts... window positioning and sizing are now preserved. - All plugin chain changes over the track properties dialog now sure counts as a dirty action (possibly fixing bug #3104129). - Newly extracted archive/zip session directories are now removed automatically from the file-system on session close, prompting the user for confirmation (cf. View/Options.../Display/Confirm Removals). - Ctrl+mouse-wheel is now set for zooming in/out, on main track-view and all applicable MIDI clip editor views (piano-roll), according to current zoom mode (see View/Zoom Horizontal, Vertical or All for both ways simultaneously). - New MIDI clip editor (piano-roll) mouse hovering effect (eye-candy++). - After too many a user request, a brand new session archive file type is being introduced (.qtz) which tries to bundle in one single zip archive all the media and contents of a session. - Add that to eye-candy: either loop or punch-in/out outer ranges are now shaded on the main track-view, thumb-view and MIDI clip editor (piano-roll) views. - LV2 GTK UI plug-in hosting is now roaring its ugly head (EXPERIMENTAL). - Ignore all initial and decremental notifications of audio engine's buffer-size changes. - Internal audio buffer loop points were not being set properly for non-zero clip offsets, leaving some as severely out-of-sync while rolling over loop turns. Now fixed again, hopefully. - Avoid audio peak file clashing when deriving from audio sample files with distinct absolute paths but the very same file (base)name. - A new MIDI editor (piano-roll) tool has been added: Rescale event times, durations and/or values by a percentage between 1 and 1000% (adapted thanks to patch #3081954, by Jesse Lucas). - Attempt to mitigate audio clip sequencing glitches on single-core/single-thread machines. cheers && enjoy (be happy!) -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

gst123-0.1.4

by Stefan Westerfeld

gst123-0.1.4 has been released. Overview of changes in gst123-0.1.4: ------------------------------------ * Fixed crash for "dumb" terminals. [Siddhesh Poyarekar] What is gst123? --------------- The program gst123 is designed to be a more flexible command line player in the spirit of ogg123 and mpg123, based on gstreamer. It plays all file formats gstreamer understands, so if you have a music collection which contains different file formats, like flac, ogg and mp3, you can use gst123 to play all your music files. Since gst123-0.1.0 support for watching videos has been added; however gst123 should run fine in situations where no X11 display is available; videos can be played without X11 display, too (-x, --novideo); in this case, only the audio stream will be played. It is implemented in C++ and licensed under the GNU LGPL version 2 Links: ------ Website: http://space.twc.de/~stefan/gst123.php Download: http://space.twc.de/~stefan/gst123/gst123-0.1.4.tar.bz2 -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

[ANN] guitarix released gx_head

by hermann

I'm happy to announce the first public release of gx_head. gx_head is a simple guitar mono tube amplifier simulation based on the work we have done in the guitarix project. gx_head provide 3 tube models (12AX7, 12AU7, 6V6) and 8 different tonestack models(Bassman, Twin Reverb, Princeton, JCM-800, JCM-2000, M-Lead, M2199, AC30), so you can simply create the amp-model to your needs. gx_head comes with a bunch of in-build effects, like distortion, crybaby, autowah, phaser, flanger, echo, delay, . . . The effects could ordered in two Racks, on for the mono effects, witch could be load for pre or post processing, and one for the stereo effects, witch could only used in post processing. Effects are loadable over the menu, a pop-up menu in the racks, or a plugin bar. Settings could saved/load as presets. gx_head comes with some factory settings provided by guitarix/gx_head friend "funkmuscle", thanks therefore. All UI controllers could connected with jack midi via MIDI learn with your external MIDI controllers. gx_head is ready for language support via gettext() and comes thanks to Pablo Fernández with a Spanish translation. The style file gx2 is contributed by zettberlin, thanks Hartmut some features in short: * 8 tonestack models * 3 tube models * cabinet impulse response module * bass boster * easy Impulse Response file support via zita-convolver * on the fly IR-file resampling via zita-resampler * Oscilloscope and tuner * multi band distortion model * scalable EQ * phaser, flanger, stereo delay, stereo echo, * overdrive, compressor, freeverb, reverb, * chorus, moog filter, low/high pass filter, . . * MIDI learn * Patch Info widget * Preset File Load/Export option * factory settings * language support * shining User Interface via GTK/gtkmm * . . . . have fun _________________________________________________________________________ gx_head is licensed under the GPL. screenshots: http://sourceforge.net/apps/wordpress/guitarix/ direct download: http://sourceforge.net/projects/guitarix/files/gx_head/gx_head-0.12.0.tar.b… download: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum here: http://sourceforge.net/apps/phpbb/guitarix/ ________________________________________________________________________ For extra Impulse Responses, gx_head uses the zita-convolver library, and, for resampling we use zita-resampler, both written by Fons Adriaensen. http://www.kokkinizita.net/linuxaudio/index.html We use the marvellous faust compiler to build the amp and effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ For faust users : All used Faust dsp files are included in /gx_head/src/faust, the resulting .cc files are in /gx_head/src/faust-cc The tools we use to convert (post-processing and plot) the resulting faust cpp files to the needed include format, stay in the /gx_head/tools directory. ________________________________________________________________________ regards guitarix development team
