Hello Everyone! Announcing for the last time this year the new release of Wav Composer Not Toilet. Wcnt is of course, the not-real-time modular synth, sequencer, sampler, wav file generator. Get it from wcnt.sourceforge.net. This release is wcnt-1.1z (read wcnt-1.1260) and here are the new features and changes: ~~~~~~~~~~~~~~~ BIG CHANGES: ~~~~~~~~~~~~~~~ *** Updated website to be more helpful + online example. *** Sets of data which are not module parameters or module inputs (shape of an adsr, notes in a riff, riffs in a sequencer, etc) have now been generalised into a base class. Specialised data reading routines have been replaced, which make it easier to program new data sets. This also means that data definitions are now more tappy tappy on your keyboard, my justification for this extra user effort is readability. *** Riffs inserted into sequencer can be transposed at point of insertion, and the note lengths can be modified. ~~~~~~~~~~~~~~~ COMMAND LINE: ~~~~~~~~~~~~~~~ *** Now has short options too. *** two conversion options to convert a note name to a frequency, and a frequency to degrees per sample and samples per cycle. ~~~~~~~~~~~~~~~ NEW MODULES: ~~~~~~~~~~~~~~~ *** dynamic Maps amplitudes of input signal to a set of output amplitudes/ratios. Of course it has two sets of which the output can be modulated between. *** spreader Spreads the output of a number of wcnt_signal modules along an imaginary line and outputs that which the modulation input lands upon. *** note_tran Translates notes into values. The note range used depends on being triggered by a note_on, or note_slide. Four output triggers so you can tell if the note was in one of the two note ranges or not. (see online example: wcnt.sourceforge.net/drumex01.wc ) ~~~~~~~~~~~~~~~ MINOR CHANGES: ~~~~~~~~~~~~~~~ *** adsr got a couple new params regarding shape modulation *** logic trigger's xor mode definately works now (dunno if it did before) *** trigger now behaves in a note_on/note_off type operation gleaned from the input signal. *** wcnt_signal has a level param That's All Folks, same time next year, see ya! see ya! see ya. see ya, see ya see yaseeyacyacyacycaaa...

[linux-audio-dev] [ANN] Radium v0.63

by Kjetil Svalastog Matheussen

http://www.notam02.no/arkiv/src/radium-0.63.tar.bz2 http://www.notam02.no/radium/ (Note, the CVS is very outdated) Radium V0.63 Alpha Linux Port Released 15.4.2004 HOW TO MAKE IT RUN WITHOUT READING THE REST OF THE README FILE make ./start.sh INTRODUCTION This is the second public, and the first official, release of the linux port of the music editor Radium. The Amiga version has been stable since January 2002. Radium is a new type of graphical (currently only) notebased music editor. For more info about the program, check out the online manual placed at http://www.notam02.no/radium/ somewhere. COMPILE The following packages are currently used to build and run Radium: *libgc - http://www.hpl.hp.com/personal/Hans_Boehm/gc/ *Python - www.python.org (at least V2.0 and tkinter) *Python development package *pyqt - http://www.gnu.org/directory/devel/specific/PyQT.html *pygtk - http://www.daa.com.au/~james/software/pygtk/ (pygtk1, use pygtk-0.6.11) *xterm - Yupp. Most of these things are allready included in the radium/ directory (mainly because of compatibility problems between various versions of gtk, pygtk and libglade), so you only need to get hold of "pyqt". "pyqt" is available as package for most linux distributions. CURRENT STATE The biggest problem is that saving does not work. Loading does though. Other things that needs to be fixed is that the playing behaves strange when reaching the end of the blocks, and that the alsa-seq code needs some care (midi/alsaseq/). ABOUT THE CODE The code is a mix between C and Python. The state of some of the code is quite horrible and ununderstandable, but relatively bug-free, eh hopefully. :) CONTACT k.s.matheussen(a)notam02.no http://www.notam02.no/radium/ --

[linux-audio-dev] how about a LADSPA BOF session at LAConf#2 ?

by Joern Nettingsmeier

hi richard, hi everyone! i'm just wading through 2k5 linux audio mails, as i'm a little behind on current affairs due to a lengthy and less-than-smooth moving of houses. after reading the LADSPA related threads of about a month ago, a couple of things became obvious to me: * LADSPA has some showstopper deficiencies to some developers * there seems to be an ongoing battle about how essential rdf metadata support should be: if it's purely optional, then many things that conceptually should be metadata must be duplicated in more or less inelegant additions to ladspa.h, and there seems to be no real consensus on how to do that. if metadata support is necessary even for simple hosts to create usable guis, we put the famed 'S' in danger. * at present, the discussion has reached the "matter of taste" point and is pretty much dead in the water. * with no real formal process for the development of LADSPA except for richard's role as the "benevolent dictator", and richard being very quiet on the matter, those developers who opt for an extension of the spec may feel there is no way to get their proposals through. * maybe for that reason, there has been some imho ill-advised rhetoric towards fait-accompli tactics. now wherever LADSPA is heading, one thing is very certain for me: LADSPA and JACK are the very two projects that absolutely *MUST* *NOT* *FORK* or even develop "local dialects" at this point in time. i'm not afraid of forks in almost all contexts, but a forked "common" api is a dead api. whatever happens, let's not jeopardize the two major kickass components of linux audio. there may come a time when LADSPA has become so inert and obsolete that we should take care of it the darwin way, but this time is still a long way off. for that reason, let's try to cram a LADSPA BOF into the already overflowing schedule at LAConf#2, or at least dedicate a "working dinner" to the future of LADSPA. i have this feeling that injecting the face-to-face factor and some german beer into the discussion might remove some obstacles. :-D richard, if you are reading this, some comment from your part would also be helpful imho. i found you have not participated in the ladspa discussions since release 1.1, which was in august 2002. it seems everyone still considers you the keeper of LADSPA, and it might clarify things if you stated * your opinion on the current discussion; * your criteria for approving extensions; * whether you are willing and have the time to retain the role of official LADSPA maintainer and to have the final say over what goes in or what doesn't, or let go of this role; * whether you can make it to LAConf#2 for a beer :) all the best, jörn -- The handles of a craftsman's tools bespeak an absolute simplicity, the plainest forms affording the greatest range of possibilities for the user's hand. That which is overdesigned, too highly specific, anticipates outcome; the anticipation of outcome guarantees, if not failure, the absence of grace. - William Gibson, "All Tomorrow's Parties" Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxaudiodev.org (Linux Audio Developers)

[linux-audio-dev] Alternative Sequencer User Interface

by Thorsten Wilms

Hi! Firt of all, since this my first post, some words about me: My name's Thorsten Wilms, I'm studying industrial design in Germany/Wuppertal. I'm very interested in interaction / interface design, and of course making music on the Linux platform. My coding skills are _very_ basic:( Used Cubase VST on Windows, but I can't stand Windows anymore, and what people around here have developed / are working on is more interesting anyway, not to forget that open-source just feels better and gives me a chance to influence things :) Ok, now the screenshot Tim Orford linked to (http://80.61.20.184/wiki/smgui_5.png) reminds me of Ableton Live. Everybody who doesn't know it should take a look at this screenshots: http://www.ableton.com/pages/products/live/live3tour/whatislive/live3sessio… http://www.ableton.com/pages/products/live/live3tour/whatislive/live3arrang… It's optimized for live usage. No pseudo 3d look, everything fast and easy to 'read'. Not that everybody should copy this right away, but it might be a source of inspiration. And now for everybody interested in a different approach to a sequencer gui, I would like to point to the 3d application Blender. It has something like it's own windowing system, whereby what is called a Window in Blender is rather like Panes in other environments. You can split windows verticaly and horizontaly and resize every window by dragging the borders. Every window (usualy) has a header (even though these can be at the bottom) wich can hold buttons and menus. But the first control in every header is for selecting the windowtype (3d view, file-browser, schematic view, ...). Setups of these windows can be saved as Screens. Shortcuts allow to switch through Screens, or to maximize the window the mouse is over to full-screen (or minimize afterwards). All this allows to adapt Blender to one's own workflow or current task at hand. Screenshots: http://wrstud.urz.uni-wuppertal.de/~ka0394/forum/04-04-10_blender_1.png http://wrstud.urz.uni-wuppertal.de/~ka0394/forum/04-04-10_blender_2.png The same approach could be used for sequencer / audio suite. To take it a little further, the windowtypes could be seperate applications / plugins. Managing various effects, synths, the mixer and everything else on a single screen in Cubase was a nightmare. I make use of virtual desktops under Linux, but a system like in Blender would be so much more comfortable and fast ... I can't code anything coming only close to such functionality, but I'm more than willing to work on conception and graphics, if there is interest. Thanks for the attention! --- Thorsten Wilms

[linux-audio-dev] MIDI transforms table redux

by Dave Phillips

Greetings: Email sucks for sending something as simple as a mere plaintext table, so here's a link to two screenshots displaying the Sequencer Plus Gold transforms: http://linux-sound.org/spg-transforms.html SPG distinguishes between "normal" transforms dealing with note-on/off messages and "MIDI/Tempo" transforms affecting MIDI controllers and tempo messages. Best regards, dp

Re: [linux-audio-dev] wcnt linear filters

At the time I wrote that I was concentrating on coding and everything else was put on hold.

I'm so used to installing software which does n't work on my machine (especially QT stuff;) that I wrongly assumed that was the case with Glame. I's using glame-1.0.1. and it works fine! I was confused by some nodes like file-reader having only one unsplit box for output even though it's (possibly) stereo, and other nodes having a split box for outputs.

Re: [linux-audio-dev] Linux soundapps pages updated

by Dave Phillips

Hi Richard: My day is rapidly turning out differently than I planned... I've added a further clarifying comment after the article. I've also decided that after next month's report on Karlsruhe, perhaps I'll do my own comparisons and see just where Linux music notation software stands in relation to its Win/Mac counterparts. That should be interesting... Best regards dp Richard Bown wrote: >On Monday 12 April 2004 13:52, Jan Nieuwenhuizen wrote: > > > >>Yes.
