Hello! If I want to output a MIDI note to all channels, what do I have to assign to snd_seq_event_t *ev; ev->data.note.channel Is there a possibility to do so in one strike, or do I ave to iterate through all 16 channels?

Thank you for your forum post about rc1. Posting announce of rc1 to dev-only lists only was intetional. The reason is to avoid user frustration that can be caused by "unpolished" software. Also devs are supposed to be able to give better feedback for crashing software. If everything goes as I expect, rc2 announce will probably be posted in laa and lau mailing lists too. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAD] [ANN] lash-0.6.0 release candidate 1

by Nedko Arnaudov

I would like to ask LASH beleivers and other interested parties to test the first release candidate for 0.6.0. Juuso Alasuutari and me have been doing some major changes to the lash code. We have done lot of work, we've fixed several big implementation issues and we need stable point before doing more changes (0.6.1 and 1.0 milestones). In the tarball there is simple lash_control script. One can also control LASH through patchage-0.4.2 and through lpatchage (availabe through git). User visible changes since 0.5.4: * Use jack D-Bus interface instead of libjack, enabled by default, can be disabled. Ticket #1 * Allow controlling LASH through D-Bus. Ticket #2 * Use D-Bus autolaunching instead of old mechanism. Ticket #3 * Log file (~/.log/lash/lash.log) for LASH daemon. Ticket #4 * Client stdout/stderr are logged to lash.log, when clients are launched by LASH daemon (project restore). Ticket #5 * Improved handling of misbehaved clients. Ticket #45 * Projects now can have comment and notes associated. Ticket #13 Download: http://download.savannah.gnu.org/releases/lash/lash-0.6.0~rc1.tar.bz2 http://download.savannah.gnu.org/releases/lash/lash-0.6.0~rc1.tar.bz2.sig -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAD] [IDEA] Amp and effects modeling software for guitar

by almbfsek＠turk.net

Hello, Few days ago I came up with an idea about an open source guitar modeling software. But because of my lack of knowledge on both electronics and audio engineering I couldn't decide if it worths something. Here it is directly quoted from linuxmusicians.com **QUOTE** Okay! My idea is to use GNUCAP or SPICE to process the guitar signal. These are the top open source analog circuit simulators that are also widely used in the industry for general purpose circuit simulation (not audio specific). You basically feed them the schematics of a circuit and wait for magic to happen. I believe they may be hacked to accept a guitar signal as a varying voltage source. Now there are 3 questions: Is that even possible? If yes, is it possible in real-time? If yes, would results be satisfying (quality and accuracy wise) **END_QUOTE** thanks very much, and sorry in advance if I missed something obvious and this is a completely useless idea

It would be great though since it would take a minimal amount of effort to make it work with a guitar signal but no real-time means the end of this idea thanks very much for the quick answers

[LAD] SMDITools with ESI4000 (Ubuntu Studio 8.04)

by Dan Richert

I'm trying to set up an E-Mu ESI4000 sampler for SMDI sample transfers on Ubuntu Studio 8.04, but I'm having some trouble figuring out how to communicate with the sampler. OpenSMDI relies on SCSI devices being listed as /dev/sga[a-n] and the SMDITools docs suggest setting up a symlink if SCSI devices aren't listed that way on the system you're using. The problem is that it appears that the ESI4000 is not being associated with a device file. Here's the output from lsscsi: [0:0:0:0] disk ATA WDC WD800JB-00FM 13.0 /dev/sda [1:0:0:0] cd/dvd HL-DT-ST RW/DVD GCC-4521B 1.00 /dev/scd0 [1:0:1:0] cd/dvd SONY CD-RW CRX230EE 2YS3 /dev/scd1 [2:0:4:0] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:1] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:2] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:3] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:4] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:5] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:6] process E-mu ESi-4000 Sampler 3.02 - [2:0:4:7] process E-mu ESi-4000 Sampler 3.02 - [2:0:5:0] disk IOMEGA ZIP 100 K.05 /dev/sdb The SCSI ID setting on the ESI4000 itself is set to 4. There is an Iomega Zip 100 drive (SCSI ID 5) between the sampler and the computer. SMDITools/OpenSMDI can be found at http://nolv.free.fr/SMDITools/ Thanks, Dan

[LAD] update of jkmeter

by Fons Adriaensen

Jkmeter-0.4.0 is now available at the usual place: <http://www.kokkinizita.net/linuxaudio/downloads> Jkmeter is a combined RMS/digital peak meter based on the ideas of mastering guru Bob Katz. New options in this release: -type k14 : K14 scale instead of the default K20. Use this for mixing to a higher average level. -A : Ambisonic (4ch) mode. -C : Adds a stereo correlation meter. Used on a Ambisonic B-format signal the correlation meter uses W and X, and indicates how 'forward' the sound stage is. Enjoy ! Ciao, -- FA Follie! Follie! Delirio vano e' questo!

[LAD] wiki.linuxaudio.org and outdated/dead projects

by Holger Ballweg

Hi list. My name is Holger Ballweg, I am a student of Musikinformatik (musical computer science?!) and musicology at the university of music in karlsruhe. I'm using Linux for quite some time now, often using audio applications. To discover new applications, there luckily is linuxaudio.org's appdb. Unfortunately many of the apps aren't actively developed, some are nowhere to be found because the homepage has vanished. I just started editing the wiki and wanted to know, if we could add a tag, which in some way makes it possible to see which projects are still active or which not. A possible solution could be to include some mechanism to show which packages were updated in the last couple years by including a timestamp for the last release (like proposed in the wiki) in the app entry and to add an to the listings, which shows projects updated in the last 12 months. I'd like to mess with the wiki some more, but first I'd like to have a possibility to mark those old projects... Cheers, Holger

[LAD] [ANN] Qtractor 0.2.2 (flirty ditz) is out!

by Rui Nuno Capela

Qtractor 0.2.2 (flirty ditz) is out! ------------------------------------ Qtractor is an audio/MIDI multi-track sequencer application, written in C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its main infrastructures and Linux as native and exclusive platform. Specially suited to the lone-wolf composer, arranger and (re)creative music-maker personal home-studio, it still hopes to evolve as a fairly featured desktop audio/MIDI workstation or at least, a prototypal part of it ;) Release highlights: * Stephen Doonan joined documentation team and revised the user manual. * Spurious MIDI events recording bug ow fixed. * Audio track monitoring and plugin loop processing slightly improved if not fixed. * MIDI clip editor improved precision and correct snapping. * Multiple track mute and solo one-click toggling (NEW). * Better MIDI connection persistance across sessions. * Record-armed tracks aren't muted on playback anymore (NEW). * Optimized audio clip waveform caching and drawing. * Many more or less fixes (see change-log) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Download: - source tarball http://downloads.sourceforge.net/qtractor/qtractor-0.2.2.tar.gz - user manual http://downloads.sourceforge.net/qtractor/qtractor-0.2.2-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. Features: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework (no Qt3 nor KDE dependencies). - Uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis), MP3 (via libmad, playback only), WAV, FLAC, AIFF and many, many more (via linsndfile). - Standard MIDI files support (format 0 and 1). - Non-destructive, non-linear editing. - Unlimited number of tracks per session/project. - Unlimited number of overlapping clips per track. - XML encoded session/project description files (SDI). - Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, delete, split) - Unlimited undo/redo. - Built-in mixer and monitor controls. - Built-in connection patchbay control and persistence (a-la QjackCtl). - LADSPA, DSSI and native VSTi plug-ins support. - Unlimited number of plug-ins per track or bus. - Plug-in presets, programs and chunk/configurations support. - Audio/MIDI clip fade-in/out (linear, quadratic, cubic). - Audio clip time-stretching (WSOLA-like or via librubberband), pitch-shifting (also via librubberband) and seamless sample-rate conversion (via libsamplerate). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - MIDI clip editor (piano roll). - MIDI instrument definitions (a-la Cakewalk(tm)) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Change-log: - Slight optimization in audio and MIDI meters refresh rate. - Another ancient bug has been squashed: MIDI events were being recorded even though recording wasn't rolling; spurious event times were being recorded due to an absent started queue. - Major fix applied to audio track monitor metering, and most importantly to plugin processing, correcting tentatively all audio buffer offsetting and slicing due on loop turnarounds. - Fixed a potential crash and/or simple record dismissal when changing properties of a track already armed for recording; prevent record engaged tracks from editing or removal. - Lighten up the connections line and highlight colors, as seen to fit best on some darker background themes. - Several icons refined with slight transparent shadowing. - Send/reset all MIDI buses and track controllers (ie. volume and panning) only when main transport playback is started, avoiding the pouring on eg. loop, playhead or tempo changes. - Pressing the Escape key also clears current selection in the main track-view and MIDI clip editor; resizing multiple events at once doesn't need help from Shift or Ctrl modifiers anymore. - DSSI and VSTi plugins get all their default parameters values reset on MIDI program change. - Several major fixes have been applied to the MIDI clip editor, regarding snap precision and correctness, most specially due on clips which weren't located on exact bar boundaries. - Brand new usability feature introduced: mute, solo and monitor toggling may now be applied to all tracks in session at once, when issued with either the Shift or Ctrl keyboard modifiers, which will set or reverse respectively all other tracks state. - Audio buses plugin chain may be also accessed and edited from the extended bus management dialog (View/Buses...). - MIDI meter level default color is now set distinct from the old lime-green one as in audio level meters. - MIDI clip editor is now a genuine top-level window, fixing all keyboard shortcut ambiguities with main application window. - Mixer splitter panes are now collapsible and optionally hidden. - Make MIDI instrument patch management a little more sane, as for preventing the accidental insertion of blank instrument names and automatic default bank/program selection in track properties. - All connections are now based exclusively on the textual client and port names, effective in particular to match MIDI bus ports with disregard to their volatile numerical identification. - MIDI file (SMF) header endianess fix (PPC users rejoyce:)) - Record armed tracks aren't muted for playback anymore, as this was a severe crippling nuisance regarding input monitoring and all mighty user experience after recording a simple take; for instance, as the bottom line goes, there's no need to un-arm a track from its record-enabled state anymore, for just recorded material get heard on immediate playback; kick on the jam! - Playhead position overflow fixed on negative MMC STEP commands. - Thumb-view width proportions now based on minimal slack session length instead of the auto-extending track-view contents width. - Optimize audio clip drawing, most specially on zoomed-out levels. - Bring the audio peak frames into some sort of cache, preventing recurrent peak frame buffer reallocation and trashing.
