Hello folks, Right on the heels of big One-O we've decided to release a minor update with some corrections, main features being some package improvements and a midi timing issue when running under very high priority. MusE : http://muse-sequencer.org [Fixes since 1.0] * Removed: Disabled watchdog thread. (T356) * Changed/Fixed: Thread priorites: Added command line switches for audio (-P) and midi (-Y). (T356) - Audio (-P) applies to dummy driver only. (Else audio priority is fixed by Jack). Fixes potential issue with midi timing when MusE was assigned a very high priority. * Added: Enable/disable LASH command line switch (-L), (if LASH support is compiled in). (T356) - Helps prevent some issues like auto-starting Jack, or automatically routing midi to fluidsynth (observed). * Fixed: BUG ID: 2879426: *.med does not save meta event types. (T356) * Fixed: Midi meters now show for each track even if they're all on same device and channel. (T356) * Applied: muse-destdir.patch Scripts and utils packaging fix submitted by Orcan Ogetbil. (T356) * Fixed: python detection exchanged for script from http://libvirt.org/ (rj) * Feature: Jack transport enable/disable in Midi Sync settings window. Stores setting per-song. (T356) - Should be Ok to use and test. Needs a bit more work. See jack.cpp and jackaudio.h * Fixed: Speedups of audio pre-fetch especially when moving the cursor around (seeking). (T356) [What is MusE again?] MusE is multitrack virtual studio with support for: * Midi (only Alsa yet) * internal softsynths, including soundfont player FluidSynth and sample player Simple Drums * DSSI softsynths, including VST instruments * with a patch to DSSI, VST-chunks are handled * Drum editor * Pianoroll * Conventional arranger * midi automation * and lots more * Audio * Jack * Jack transport * LADSPA plugins * VST plugins through dssi-vst * audio automation, old sch00l * and lots more [ChangeLog] For a complete list of changes, check the ChangeLog in the package or online at the sourceforge site: http://lmuse.svn.sourceforge.net/viewvc/lmuse/trunk/muse/ChangeLog?revision… [Download] http://muse-sequencer.org/index.php/Download The MusE team

yoshimi 0.053-pre2 reports "unknown version 1.0110" for various .cxx files?

by david

Downloaded 0.053-pre1 (it wouldn't run after being built, "staged a strategic retreat"). Then downloaded 0.053-pre2, and make displays the following: [ 7%] Generating VirKeyboardUI.cxx /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/VirKeyboardUI.fl:2: unknown version '1.0110' [ 8%] Generating ConfigUI.cxx /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/ConfigUI.fl:2: unknown version '1.0110' /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/BankUI.fl:2: unknown version '1.0110' [ 16%] Generating PartUI.cxx /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/PartUI.fl:2: unknown version '1.0110' [ 17%] Generating MicrotonalUI.cxx /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/MicrotonalUI.fl:2: unknown version '1.0110' [ 18%] Generating MasterUI.cxx /home/david/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src/UI/MasterUI.fl:2: unknown version '1.0110' Trying to run yoshimi produces this: david@eurolap:~/yoshimi/yoshimi-0.053-pre2/yoshimi-0.053-pre2/src$ yoshimi Error, failed to start Alsa midi thread: 1 Error - bail out of AlsaEngine::Start() Error, failed to cancel Alsa midi thread So sad, failed to start MusicIO Yoshimi stages a strategic retreat :-( I went back to 0.047.1 and tried, got same unknown version messages, and still wouldn't start. So I rebuilt 0.036, get no unknown version messages, but now it reports "Info, other non-handled midi event, type: 36". Never got that before! At least Yoshimi 0.036 runs for me.

[ANN] Qtractor 0.4.4 - The Frisky Demivierge's in the wild!

by Rui Nuno Capela

[ANN] Qtractor 0.4.4 - The Frisky Demivierge's in the wild! What? No automation, yet? Yes I failed the promise once again. So what? What would you expect from this self-called über-procrastinator? As sure is one to say that this is the Year of Linux Desktop (YOLD:), I'll give you the shivers and command this one will be the year of Qtractor Automation. No kiddin' ;) Meanwhile, this new dot-release brings you several niceties, a couple of them have been waaay longer and dustier on the all-mighty-overdue TODO list than automation is. Rejoice! or else... Qtractor 0.4.4 (frisky demivierge) is in the wild! Release highlights: * LV2 plug-in support (NEW) * MIDI event list view (NEW) * Expedite audio/MIDI clip import (NEW) * DSSI plug-in output control ports feedback/update (NEW) * JACK transport, MMC, SPP control options (NEW) * Self-bounce/recording (FIX) * Audio/MIDI drift correction (FIX) * Anti-glitch audio micro-fade-in/out ramp smoothing (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.4.tar.gz - source package (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.sr… - binary packages (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.4-2.rncbc.suse112.x8… - binary packages (Ubuntu 8.04 LTS; no LV2 support): http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu804_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu804_… - binary packages (Ubuntu 9.10): http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu910_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.4-1.rncbc.ubuntu910_… - user manual (ever still outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-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: - For all the DSSI plugins that have output control ports, a host feedback/update process cycle is now being finally provided: all output control ports are now marshaled to their respective GUI process, rather often and when found open/visible. - MIDI clip editor (aka piano-roll) snap-to-beat behavior on edit mode is now kind of more like 'filling-in-the-blanks' (as Frank Neumann et al. wishes ;) - Fixed MIDI clip editor mistake when reverting to initial clip length, before closing and discard changes (thanks to Frank Neumann, for spotting this one). - LADISH Level 1 support has been added: SIGUSR1 signal trap just makes it a shortcut to File/Save. - Avoid parameter value flickering, due to duplicate command invocation, most evident when changing values massively on native Linux VSTi plugin editor GUIs (thanks to a detailed report on this odd behavior, from Mike of linuxDSP.co.uk). - Another TODO item bites the dust: MIDI event list editor, now accessible from the MIDI clip editor menu (View/Events) - Last used session directory is now made current on startup only when no filename is given on the command line (solving bug #2920244). - Current snap-to-beat setting (time quantization) now affects the anchor event only, while dragging, moving and/or pasting multiple events over the MIDI clip editor (aka piano-roll). - Make anti-glitch audio clip micro fade-in/outs independent from current buffer size as much as possible. - Audio/MIDI engine drift correction gets really sophisticated, with the help of (now old) ALSA MIDI tempo skew facility. - Edit/Clip/Import... menu option is now available for expedite clip insertion from audio and MIDI file requesters. - Set default session directory effective to file's location. - Audio track/clip recording process has been target to special re-factorization across the internal audio engine process cycle, in a late attempt to get self-bounce/recording effective and working consistently for all track layouts. - All session related dialogs are now set to window modality, (were set to default application modality before) allowing for continued input focus and interaction on all plugin/tool windows. - An off-by-one nasty old bug fixed in audio clip drawing, was causing instant crashes on certain zoom levels of the main track view. - Graphical MIDI clip representation regarding note/pitch range is now kept as much as possible across clip edits (cut, copy, paste, drag, move, delete, etc.) - LV2 plug-in hosting has finally come into actual implementation; only some and the most basic LV2 plug-in features are supported at the moment; probably there's no big advantage against the old LADSPA ones; there's some support for external UIs though; also, LV2 MIDI/Event bare-bones support is included but chances are it won't build nor work right on most of the setups out there. It's a WIP host implementation anyways, as is the whole LV2 spec. for that matter ;) - Connections filter is now reset when widget is shown through the View/Connections main menu or toolbar button. - Audio bus auto-connection option is now applied when creating or updating, newer or existing buses, respectively. - Global configuration state is now explicitly saved/committed to disk whenever View/Options... dialog changes are applied or when a session is loaded or saved. - Audio ramping spin-locking makes its smooth stuff, in an attempt to reduce glitching and crackling when editing (due to its own pseudo spin-locking) and toggling playback states. - JACK Transport, MMC Device, and MIDI Song Position pointer (SPP) control modes are now made optional (View/Options...), allowing for discretionary configuration: None/Disabled, Slave/Input, Master/Output or Full/Duplex (default). - Session files may now be dragged and dropped over the main track view and get loaded for business as usual (once quietly ignored). - In an attempt to mitigate potential stack corruption and sudden crashes, old commented out session pseudo-locks are now back in business while executing clip editing commands (cut, paste, drag, move, insert, delete) and playback is currently rolling. - Adjusted first-time application window size to fit into 800x600 screen size and with reasonable initial dock-ables layout. - Avoid duplicate snap-to-grid effect when changing the length of MIDI clip editor events across non-zero clip offsets (after a glitch reported by Ralf Mardorf). - Late audio track processing optimization, suppressing all plugin, mixer and monitor pass-through activity when given track is muted, either explicitly or implicitly (ie. other track is in solo state). - Entering System Exclusive events (SysEx) on the MIDI clip editor (aka matrix/piano-roll widget), yet something not fully supported anyway, even though allowed in edit mode, doesn't crash the whole damn thing anymore, while saving the clip to a file. - Strict aliasing avoidance, with plain and demanded use of 'union', as much as to stop nagging warnings from gcc >= 4.4.1 (last seen on src/qtractorMidiEvent.h hackery). - Visual correct play-head position while changing zoom levels, applicable to both main track and MIDI clip editor views. Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

fmit shows an octave too low

by Fritz Meissner

Just been playing with fmit (version 0.97.7 form the Ubuntu ropo) on my netbook (Acer Aspire One/UNR 9.04). I find that it consistently shows notes an octave low (half the correct frequency). For instance, the A above middle C is reported as 220 Hz instead of 440 Hz. I've tried playing with the settings (and also restore to factory settings) but it makes no difference. Any ideas on what to do about this ? Fritz

Support for RME HDSPe laptop expresscard

by Brent Busby

Since I already have an RME Multiface II setup with the PCI-E card for desktop systems, I've been mulling over the possibilities of also doing mobile on-site recording with a laptop, using my existing Multiface II external i/o box with their ExpressCard for laptops. I would be able to use the same Multiface box on both laptop and stationary recording machines, and just buy the ExpressCard. I wondered if anyone here is already using the laptop card, and whether it shows up in Alsa properly, since it isn't a normal PCI card.... Also, I wondered if anyone has any recommendations for laptops for recording. The Sony Vaios look nice and are very light, even in their full size notebooks, but I'll never forget how badly the whole Vaio series worked with Linux back in the 90's. Are they decent now? What other laptops are there that might work well? Note: I *strongly* prefer something with an ATI video chipset. My experience has been that going with anything else on Linux is begging for some kind of pain. -- + Brent A.

[OT] Unistalling programs

by Marco Castorina

Hi there, maybe for many of you this is an easy task, but I still don't know a way of disinstalling programs installed by src (that is not using deb packages, as I'm on Ubuntu). Of course they don't appear in synaptic and, even looking around the web, I didn't find any working solution. Any ideas or suggestions? Thanks in advance, Marco Send instant messages to your online friends http://uk.messenger.yahoo.com
