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

by Aaron Johnson

Porl, linux-audio peoples, 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.

by Aaron Johnson

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

by Christian

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I'm currently thinking about using lash for my project. But their website is down, when I used it a year ago it was worked like crap with crashing etc. Therefore I'm wondering how the actual state of this project is(is it stable?) and if you recommend using it for developing.

[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

LAC 2009 videos available

by Jörn Nettingsmeier

hi everyone! the videos from lac 2009 are being made available at http://lad.linuxaudio.org/events/2009_cdm/videos/ . most of the footage is there - the missing stuff will follow in a few days as florian (aka faberman) gets home from a production in italy and finds time to encode the rest. the video quality this year is quite stunning - thanks to the theora team for huge improvements in efficiency and quality. if you are a video person and haven't upgraded to the thusnelda branch encoder, do it NOW (before even going for a coffee). then hit #theora on freenode.net and sign hymns of praise until they kick you out. you will note that the videos are raw - they could use trimming some talks consist of several fragments that need concatenating, but due to some stream problems they caused oggCat to barf, even though every single fragment plays ok. your help is appreciated - get in touch with me off-list or via l-a-d if you have worked on the stuff and would like to upload your improved version. best regards, jörn

Thoughts on a midi-sequencer based on notation.

by Nils Gey

(Sorry for crossposting, but according to the statistics there are many people who are in only one list and I want to hear the opinion of both devs and users) Hi people, If would like you to have a look at my initial thoughts about live-midi with notation, or the developing of a notation-based midi sequencer (for Denemo). It would be interesting to hear your thoughts, additions or comments (besides "You made a spelling/grammatical error"). http://denemo.org/index.php/Join_the_team!#Live_MIDI_out Of course if you are interested in this or other things your help would be welcome, we are always searching for help @ Denemo. Denemo is a Open Source Music Notation Editor, based on lilypond and written in C. (And I know no better one :) greetings, Nils Gey Cologne http://www.denemo.org

Jamin's multiband EQ as LV2 plugin ?

by James Warden

Hello, Just joined the list. I was toying with the following idea: take jamin's graphical multiband EQ and reshape it into an LV2 plugin. Is this a redundant idea in case someone else is already working on something similar ? Just let me know before I start looking into this. Cheers, J.
