[LAD] Yoshimi 1.1.0

by Jeremy Jongepier

Dear all, There she is, Yoshimi 1.1.0! Looking better than ever, working better than ever, capable of doing more than ever. Simply put, better than ever. Made possible by the much appreciated and very valuable help, contributions and feedback from the Linux Audio community. http://downloads.sourceforge.net/yoshimi/yoshimi-1.1.0.tar.bz2 For this release I'd like to thank the following people in particular but in no particular order: * Kristian Amlie for making Yoshimi less CPU hungry. * Andrew Deryabin for making Yoshimi a little more CPU hungry again, but for a good reason, Yoshimi now has per part JACK outputs! * Nikita Zlobin for having Yoshimi handle state files better. * Florian Dupeyron for his custom best of My?terious bank. * Will J. Godfrey for his continuous testing and monitoring of new developments. * Alessandro Preziosi for Yoshimi's lovely new knobs. * David Adler for the AZERTY virtual keyboard support. * Rob Couto for the helpful insights and general help. * Alan Calvert. Best regards, Jeremy Jongepier

[LAD] Two strange problems

by Fons Adriaensen

I'm preparing a seminar that will take place tomorrow (4 May), it will involve live mixing of surround sound using Ardour. While setting up the PC to be used, two problems occured. The first one is solved, but its cause remains misterious. A some point it appeared that the sound card (HDSP-MADI, used every day since years) had decided to meet its creator. Every program trying to access it - from jackd to aplay -L not only blocked, but turned out to be impossible to kill. Replaced the card - same result. It turned out to be a corrupt /var/lib/alsa/asound.state. The systemd service doing the 'alsactl restore' while booting choked on it, blocked, and this apperently blocked all others trying to use the card later. What I don't understand is how alsactl exactly failed, and why these processes seemed to be immune to a 'kill -9'. The second one is an Ardour2 session that worked perfectly on another similar PC, but becomes completely unresponsive on the one to be used. It has four mono tracks and three 10-channel ones, and little else. DSP load is not the problem, it's less than 15%. Things look like it's the graphics. When Ardour's playhead reaches the right end of the editor window, it takes something like 5 seconds for the editor display to update - everything seems to freeze during that time but audio is not interrupted. Same when trying to scroll or change the zoom factor. Video card is Nvidia GeForce 7300, indeed quite old, but the same PC does full-screen HD youtube videos without problem. Video driver is nouveau as nv seems to be no longer supported by Archlinux. I'm pretty sure this system didn't have such problems when it was using nv. OTOH nouveau works very well on other systems... I could try and install the proprietary Nvidia driver, but with just some hours to go I'd rather not take any risks... Any hints ? Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

[LAD] How do I write meta data into a wave file? (Command line tools?)

by Nils Gey

Hello list, libsndfile-info shows various useful information like the one at the end of this mail. I have Sonatina Symphonic Orchestra waves here (violins 1) and a one note wave includes "Midi Note", "Loop Count" and "Cue Start : 92078 End : 223977", which is the actual loop start/end Is this custom data or does it follow a standard? And no matter what, how do I write that into my own wave files? I would prefer command line tools. But programming interfaces are fine as well.

[LAD] Laborejo 0.7: Non-Session-Manager support, Playback Cursor, Numpad Palette

by Nils Gey

Laborejo 0.7 is released. Together with a new website design http://www.laborejo.org comes a new release of the Music Notation Workshop. Besides the usual fixes and small enhancements please focus your attention on the following new features: -Non Session Manager support. Start Laborejo through the NSM Gui and it will be under session management -Numpad Palette and corresponding shortcuts. A gui widget shows you what musical objects your numpad will insert. You can change the palette through the menu or by switching through with numpad-plus and numpad-minus. -A moving playback cursor, showing you which part of Bachs "Kunst der Fuge" you currently don't understand Laborejo -Music Notation Workshop- is a graphical user interface for Lilypond, a MIDI creator and finally a tool collection to inspire and help you compose. You get beautifully engraved notation through Lilypond and nice ways to control the playback without ever leaving a notation-based environment.
