Hello all, I'm having some problems viewing the LAC videos. Totem (launched by Firefox) produces perfect image but no sound (this may be related to my previous post about alsa card order). Downloading the file and trying mplayer (compiled today) I get video: no video and no sound either. All this on a fresh F10 install wich probably needs some more tuning/pruning. Ciao, -- FA Io lo dico sempre: l'Italia è troppo stretta e lunga.

making 'whysynth' microtonal/tuning-table capable

by Aaron Johnson

Porl, linux-audio people A SCALA scale library interface would be a fantastic idea....I did something like this as an exercise in Python for turning SCALA .scl files into tuning dump commands for fluidsynth (even though SCALA itself has fluidsynth scale output :) ) One could use regex statements to parse the header, and have some case switches to determine if the line in the scale 'body' of the .scl file was a ratio, or value in cents, etc. The synth engine would work with the final array of frequencies that were spit out into a MIDI-key indexed array.... I think this would be the easier part. The harder part, and where I think I'd need help, is integrating such functions into an existing audio architecture, plus integrating new GUI dialogs and menus into the same...it might take a whole to figure out if other things get broken as a result...I'm thinking for instance of envelope scaling being related to absolute pitch in HZ instead of MIDI note numbers. I haven't dug deep enough into the 'whysynth' code to see, but such things might need to be redesigned, and it might take time to work out any side effects of shoving SCALA interface code into the mix....maybe if Sean Bolton is on the list here, he'd have some insight into how to best fit things in with his existing code.... Perhaps the SCALA interface library could have a modular template of GUI dialogs/controls/menus for the more popular libs like GTK, FLTK, KDE, TK, etc.? Anyway, I'd be happy as a pig in %^&* to see this in whysynth, and as a de facto standard library the same way jack is in any synth application now written.

Re: [LAD] making 'whysynth' microtonal/tuning-table capable

Jens, Hi, thanks for the reply....your proposal gets us halfway there, but I'm thinking more being able to load SCALA files at runtime, have them parsed, and then load the array...this is what I meant by 'dynamic'...a finite number of fixed scales > 1 is better than 1, but still, ideally, we'd want some flexibility, no?

Current state of lash

[ann] QuteCsound 0.4.1

by Andres Cabrera

Hi all and sorry for crossposting... I'm happy to announce a new version of QuteCsound (0.4.1). This release is mostly a bug fix and usability enhancement release, but it also contains a few minor useful features. One of the highlights is localization in Spanish, German and French. QuteCsound is a simple frontend for Csound featuring a highlighting editor with autocomplete, interactive widgets and integrated help. It is a cross-platform drop in replacement for MacCsound (it can open files created in MacCsound), and aims to be a simple yet powerful and complete development environment for Csound. QuteCsound 0.4.1 has been tested on Windows, OS X, Linux and Solaris, and it is free software released under the LGPLv2 or at your option GPLv3. You can get it here: http://sourceforge.net/project/showfiles.php?group_id=227265&package_id=275… There's more information here: http://qutecsound.sourceforge.net/ You can download a Quick Reference pdf document in English, Spanish or German here: http://sourceforge.net/project/showfiles.php?group_id=227265&package_id=319… Questions, comments and suggestions can be posted to the main Csound mailing list, or join the QuteCsound users mailing list at: http://lists.sourceforge.net/lists/listinfo/qutecsound-users Thanks to Joachim Heintz for continuous feedback, translation and examples, François Pinot for the french translation and Andy Fillebrown for the Windows installers and fixes for Windows issues. Enjoy! Andrés New in 0.4.1: -Many new examples -Licenced under the LGPLv2 and GPLv3 -Print action in the menu (to print csd text) -Spanish, German and French localization (many thanks to Joachim Heintz and François Pinot) -Line number display in status bar -OK button is now the default button (activated with enter) for widget preferences -Quick Reference pdf in English, Spanish and French -Improved indent/unindent and comment/uncomment Fixed: -Greatly improved performance for code highlighter -Greatly improved performace for large graph display -Highlighting of error line -Open from finder on OS X -Various permission problems for temporary files -Fixed buttons showing correct status of panels on startup -Improved console message handling -Improved internal handling of values in slider and knob -ScrollNumber widget now propagates its value correctly to other widgets -Added xpm version of icon to reduce dependency on imagemagick for Debian packaging -Fixed external program launching on windows
