I've seen this behavior once before, when first working on LASH support, and it turned out to be a character encoding problem with LASH supplied directory names. The only thing I can think of here is to use the "C" locale instead of obtaining locale from the user's environment, so I've made this change in v0.14.97-dev. Could you try the latest in git, and let me know how it goes? Thanks, --ww

Re: [LAD] [LAU] [OT] digital mixer losing its presets after battery replacement

IIRC for my Yamaha DX7 and the C64 software I've written, it was an issue, when naming a sound with a special Japanese ASCII sign. AFAIR it was only the combination of one sound + a special name including this sign, not an issue when using this sign for other sounds. Voodoo ;). The old (first) DX7 itself only provided capital letters, numbers and the dot, perhaps a few additional signs, my sound bank manager enabled usage of other ASCII signs. -- FreeBSD 9.1-RELEASE amd64

[OT] digital mixer losing its presets after battery replacement

by Dave Phillips

Greetings, The subject says it all. I recently had a tech replace the batteries in two Yamaha DPM11 mixers. As expected, all presets were lost, but I was able to restore them by a direct sysex transmission from one unit to the other (before that one's battery replacement). Alas, the transmitted data doesn't "keep", i.e. when the machine is turned off the battery appears to be draining its charge, because the presets are gone when I power up again. Grrrr. Also, simplesysexxer seems to receive and transmit a bulk dump with no problems, but the units do not respond correctly. The first preset gets copied, then I receive an error code "cE". I could make good use of the machine's error code definitions now, but the only service manual I found available on the net is from a private dealer who wants too much money for it. I'll try contacting a retired Yamaha tech in Toledo OH, but does anyone on these lists have an idea what I should do ? Btw, the units work fine now, they just don't keep their presets. Any & all assistance greatly appreciated ! Best, dp

[ANN] Sqorlatti 0.1.2 (music notation program)

by M Donalies

Currently, it's just for display and editing. There's no playback yet. And it's still pre-alpha, so you can expect it to crash without expending too much effort. The biggest change is that I've implemented some of the edit boxes in the track, clip, and unit dialogs. The fun one to play with is changing the staff type (in the track dialog). Another important addition is that it's now possible to start from an empty score and add tracks, clips, and events. Unfortunately, you can't add tablature tunings from within the program yet. And adding notes to chords and tuplets still causes problems. There's no change to the font, so if you were brave enough to try out the previous version and still have the font loaded, you don't need to reload it. I put a commented out line for the -fpermissive flag in the project file. I'm hoping it's not needed anymore. If it is needed for compile, please let me know, since it means I'm doing something wrong with one of the template classes. Website: http://sourceforge.net/projects/sqorlatti Download (bzipped source tarball): http://downloads.sourceforge.net/sqorlatti/sqorlatti-0.1.2.tar.bz2 It's written in C++ and uses Qt. There's no config or anything yet, just a Qt project file. So, as an ordinary user: 1. Unpack to a directory of your choice and cd to it. 2. qmake 3. make 4. Install the Sqorlatti.ttf font. It's located in the fonts subdirectory. In KDE you can install it by going to System Settings and clicking through the tabs Computer Administration / Font Installer / Personal Fonts / Add. 5. To run, type ./Sqorlatti [filename] where [filename] is an optional *.sqo file to open. A few example files are in the examples directory. Changes in Sqorlatti 0.1.2: * Cleaned up include file paths. * Fixed SqMainWindow::openStaffEditor() so tracks appear in order of selection. * Added a few user-editible preferences. * Fixed crashing after SqMainWindow::fileNew() by cleaning up MasterView. * Allow adding Clips in Track dialog editor. * Added undo for EventContainers (Clips Track, Unit, and Score). * Allow changing staff type in track dialog. Note that if there's no tab tuning, staff type defaults to std notation. Known problems still not fixed: * Adding/removing notes to chords or tuplets. Eventually causes crash. * Undo for inserting events and containers through MasterView not combined into a macro, so separate commands are issued for insert and edit. It's not really wrong, just inconvenient and confusing. * Changing or editing tab tunings not yet implemented. This means that you can't create a new file within Sqorlatti that will display tablature. You can, however, open examples/Tablature.sqo, edit it, and save it under a different name. If you want different tab tunings (i.e. anything other than a standard guitar), you have to edit the *.sqo file by hand. This should all be fixed by version 0.1.3. -- 7:8

[ann] CAPS 0.9.4

by Tim Goetze

New in CAPS 0.9.4: * selectable oversampling ratios for AmpVTS (2x,4x,8x) * selectable sounds for Click (box, stick, beep; the second being very close to the sound of the unit in 0.4.x) * further smoothening of ChorusII modulation * selectable oversampling ratios for Compress (2x,4x) Also, a serious issue with Compress has been fixed: gain had been applied before saturation, greatly reducing the effectiveness of the unit. It's squashing smoothly now :) The 10-band Eq has been fixed and now has a reasonably flat frequency response. http://quitte.de/dsp/caps.html http://quitte.de/dsp/caps.html#AmpVTS http://quitte.de/dsp/caps.html#Compress http://quitte.de/dsp/caps.html#Click http://quitte.de/dsp/caps.html#Eq

[ANN] Sqorlatti 0.1.1 (music notation program)

by M Donalies

version 0.1.1 fixes a few bugs: *Fixed bug when not passing in a filename at startup. *Added COPYING file. Added copyright templates to src files. Fixed About box text. *Fixed some undo/redo problems with drag & drop of events. Editing notes within chords and tuplets still have problems. My announcement for version 0.1.0 didn't seem to make it to the list, so here's a repeat: Yet another music notation program to pollute the internet. It's still just a baby, but it already implements at least a few bugs. It's not really ready for general use yet. The user interface is still rather lacking and there are way too few sanity checks, but it does read and write native *.sqo files (an xml format), and supports a crude and low-quality export to standard MIDI files. The Staff Editor can display standard notation and tablature moderately well, and work is ongoing to produce better percussion staff and chord staff display. Tracks can be nested. Staffs can be grouped. The score format supports multiple simultaneous time signatures. Currently, it's just for display and editing. There's no playback yet. Website: http://sourceforge.net/projects/sqorlatti Download (bzipped source tarball): http://downloads.sourceforge.net/sqorlatti/sqorlatti-0.1.1.tar.bz2 It's written in C++ and uses Qt4. There's no config or anything yet, just Qt project file. So, as an ordinary user: 1. Unpack to a directory of your choice and cd to it. 2. qmake 3. make 4. Install the Sqorlatti.ttf font. It's located in the fonts subdirectory. In KDE you can install it by going to System Settings and clicking through the tabs Computer Administration / Font Installer / Personal Fonts / Add. 5. To run, type ./Sqorlatti [filename] where [filename] is an optional *.sqo file to open. A few example files are in the examples directory. If you open Staff Editor and the staffs looks huge and filled with garbage characters, you forgot to install the font. UserManual.pdf provides a small amount of documentation on how to use the program. It's not all that well developed yet. Developer documentation can be generated using doxygen. Just type doxygen to generate html documentation in the doc directory. You can fiddle with doxyfile if you want to generate documentation in other formats (e.g. latex). -- 7:8

Four decks audio player for radio stations

by Adrian Knoth

Hi! I was recently helping a small Dutch radio station run by volunteers to set up their new studio. It's a modular system with a 16 I/O firewire card: http://www.d-r.nl/AXUM/AXUM.htm We managed to support it in FFADO. The playback software runs on a virtualised Windows machine that's talking to jackd via netjack (no idea which one, the one with multicast and netmanager), so we can address four individual stereo pairs. This whole netjack thing isn't very stable, so the playback software should be replaced by some native Linux client. Here's a screenshot of the current Windows solution: http://adi.loris.tv/radio.png It is basically a set of four remotely controlled winamps (with ASIO output plugin to talk to jackd) and a directory browser per player. So "Jingles", "Muziek" and "Bladeren" are just shortcuts to directories with media files, the drop-down menu on the left contains a list of even more directories. The filter is used for pattern matching. Questions: Are you aware of any Linux solution that comes close to this? If not, any recommendations if one would want to create such a four-deck player? Leveraging VLC, mplayer, gstreamer? This is surely going to be open source, so whoever is interested, feel free to participate. Cheers

Ubuntu: gstreamer1.0 MP3 playback broken?

by Adrian Knoth

Hi! Any Ubuntu users around, "quantal" or "raring" release? If so, could you test if your gstreamer1.0 installation can play MP3s? Recipe: 1. Install everything with gstreamer1.0* in its name, maybe $ sudo apt-get install gstreamer1.0* does the trick If you want finer control, I guess gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools is the proper set of packages. 2. Run the pipeline: $ gst-launch-1.0 uridecodebin uri=file:///path/to/foo.mp3 ! fakesink Instead of "fakesink", you can also try "autoaudiosink" or the even more complex "audioconvert ! audioresample ! jackaudiosink", but that's actually not the question. In the good case, it looks like this: adi@chopin:~$ gst-launch-1.0 uridecodebin uri=file:///tmp/foo.mp3 ! fakesink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 2085409390 ns. Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... In the bad case, you'll get error messages about codecs or a pipeline that doesn't want to preroll. Any feedback would be highly appreciated, it'd save me from installing Ubuntu into a VM. ;) TIA PS: Feel free to file bug reports if it's really broken.

Thanks Adrian, This is now in git v0.14.97-dev. The jack_bufsize crash you reported on github is also fixed. These seem to be the last of the build/crash issues with v0.14.96, so now I can concentrate on getting v0.14.97 out by the end of the week. Cheers, --ww
