[LAA] [ANN] new version of ssg (Simple Sine Generator)

by Nedko Arnaudov

New version of Simple Sine Generator is available. It now requires lv2core. Simple Sine Generator is very simple instrument/generator plugin with midi in and audio out ports. It expected to be useful for testing LV2 hosts and as base for writing your own plugins. It is written in plain C. http://nedko.arnaudov.name/soft/ssg/ http://nedko.arnaudov.name/soft/ssg/ssg-20080109.tar.bz2 http://nedko.arnaudov.name/soft/ssg/ssg-20080109.tar.bz2.sig -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAA] SLV2 0.4.2 Released

by Dave Robillard

Hi all, SLV2 is a C library to make the use of LV2 plugins as simple as possible for host applications. Unlike LADSPA, LV2 is (more or less) designed with the assumption that hosts will use a library to discover/load/use plugins. SLV2 is one such library, which does the Right Thing with as little burden on host authors as possible. This release corresponds to the new stable LV2 release, Revision 1. More information, API documentation, and downloads can be found here: http://drobilla.net/software/slv2/ Enjoy, - Dave Robillard (aka drobilla)

[LAA] LV2 Released

by Dave Robillard

Announcing the first stable release of the LV2 specification. LV2 is a simple but extensible successor of LADSPA, intended to address the limitations of LADSPA which many applications have outgrown. By creating LV2 "extensions" (which can be done independently), virtually any feature is possible for LV2 plugins and hosts. This release (revision 1) has been in active use by many projects for several months, including several extensions for advanced features beyond the capabilities of LADSPA or DSSI. Strong long-term compatibility is a primary goal of LV2: all future revisions of LV2 will remain backwards compatible with previous revisions. All the components of the "core" LV2 specification are packaged here: http://lv2plug.in/spec/lv2core-1.tar.gz Distributions are encouraged to include this package. More information, downloads, and links to LV2-using projects can be found at: http://lv2plug.in/ Happy hacking, ~ The LV2 team

[LAA] [ANN] jack-keyboard 2.2

by Edward Tomasz Napierala

Version 2.2 of jack-keyboard can be downloaded from http://pin.if.uz.zgora.pl/~trasz/jack-keyboard/jack-keyboard-2.2.tar.gz jack-keyboard is a virtual MIDI keyboard - a program that allows you to send JACK MIDI events (play ;-) using your PC keyboard. It's somewhat similar to vkeybd, except it uses JACK MIDI instead of ALSA, and the keyboard mapping is much better - it uses the same layout as trackers (like Impulse Tracker) did, so you have two and half octaves under your fingers. -- If you cut off my head, what would I say? Me and my head, or me and my body?

[LAA] [ANN] Qtractor 0.1.0 (frivolous debutante) released!

by Rui Nuno Capela

Can't hold it anymore... :) Since its primordial presentation on the LAC2007@TU-Berlin, almost one year ago, I guess it's finally ready for an official public release. So here it goes. Qtractor development has been going stealthy but has been matured nicely. Still alpha however, but quite practical nevertheless. Or so I believe. Yes, things might get bumpy, faster or slower though, we never know in advance. And quite frankly I don't give a damn whether how it might progress from now. But it will progress, that's what I shall write here engraved ;) Trust me. Qtractor has been my hobby, kind of personal purpose in life and should stay in that status for quite some time. You probably have noticed there's too many buts in this discourse of mine, and guess what? there follows some more for your pleasant delight. As long as all its ecosystem bears sustainability; no hidden thoughts; it's all about JACK, ALSA and ultimately Linux that I'm counting on. I've made myself ascertain: I will make no effort, whatsoever, in doing any kind of cross-platform dance. Although it seem feasible, just don't expect that kind of behavior from this side of the party. I'm not obliged to. I'm happy now with what I've got and to what has been achieve in this recent years. Linux is my home and you better get it right, I'm comfortable with it. It could be seen as my "masterpiece", although you might find I'm no master at all. Take it as my pet project, because, in fact, it is just that, really! If you feel minimally interested, you might want to come along and be welcome. I'll cherish you, that's what friends are. Willing to share the journey, and follow the turns. No commitments, just fun! Now, after that bunch of BS, let's get the facts straight, right behind the thoughts: Qtractor 0.1.0 (frivolous debutante) has been released! Good grief. As always, everyone is welcome to grab the source and also some selected binary packages, available from the official project site: http://qtractor.sourceforge.net http://sourceforge.net/projects/qtractor Direct link for the source tarball download: http://downloads.sourceforge.net/qtractor/qtractor-0.1.0.tar.gz For the clueless, a refurbished whitepaper is also available: http://downloads.sourceforge.net/qtractor/qtractor-0.1.0-whitepaper.pdf Also of note is this (strong) invitation to follow my personal blurbs, right from the upstream blog and forum site: http://www.rncbc.org Here follows the change-log. as recorded since that one last previous pre-release, which was tagged as 0.0.9.778 (adolescence prime) on the late year: - Audio clip time-stretching makes its debut, with code adapted and refactored from the SoundTouch library, under the (L)GPL umbrella. - New "Options.../Audio/Playback/Quick seek time-stretching" global option, providing a quick seek mode (hierarchical search) while doing all audio buffer time-stretching. - Changing session tempo will automatically apply the corresponding time-stretch percent factor to all in-place audio clips. Audio clip dialog also includes a new time-stretch property setting. - Tempo changes are now affecting clip offsets correctly, keeping the clip offset constant in time units (ticks), as are clip start and length properties already. - Mixer splitter sizes are now properly saved/restored when hidden. - Extended multi-selection is now featured on the files widget; all drag and drop functionality has been almost completely rewritten. - SSE optimization is now enabled where available (via configure). - Options for having separate dedicated ports for the audition/pre- listening player output, audio metronome output, MIDI control input/output and MIDI metronome output, are now in place. - A brand new subtle option sneaks in, affecting the drag-and-drop of the main track-view: View/Options.../Drop multiple audio files into the same track, whether to drop multiple external files into new or existing track as concatenated audio clips. - The audio metronome makes its debut as an alternative to the MIDI existing one; parameters include bar and beat audio sample files, accessible from the View/Options.../Audio/Metronome dialog. - Files widget action refactorization; the files context menu gets its due item icons and a new menu item for direct audio player accessibility. - MIDI time resolution changes (ppqn, ticks per beat) now tries to keep all session MIDI clip times unchanged as far as possible. - MIDI channel volume and panning control change events, CC#7 and CC#10 respectively, are now rendered unfiltered on playback . - First rendition of the long due implementation of an audition or pre-listening audio player is now in place; the files window got this new play/stop control button on its lower-right corner. - Actual instrument definition note (keys) and controller names are now in effect on the MIDI editor, whenever applicable. - Fixed instrument bank selection method, "Bank MSB" (2), which was broken enough to never send the correct bank number. - Mouse-wheel horizontal scrolling is now accessible on every view, while pressing a modifier key (Shift or Ctrl). - New auto-backward transport option: when enabled the playhead will be reset backward automatically whenever transport stops playing. - A suicide-crash has been fixed while invoking the bus dialog from the respective mixer bus strip context menu. - Master (default) buses are always set to Duplex mode, being now an enforced update policy while on the Buses dialog. - A stupid lockup bug (infinite loop) was spotted on the track bus assignment method and squashed (thanks, lexridge). - New keyboard shortcuts for toggling the Connections tool (F8) and the mighty Mixer tool (F9) windows. - Avoid showing a context menu while right-clicking on time rulers. - Audio clip waveform drawing gets additional closing points. - It is now possible to change the length/size of a clip by dragging its left or right edges, while in the main track-view. Shift+drag will also time-stretch to the resulting audio clip length. - Another off-by-one mistake was corrected, which was causing audio clips to go out-of-sync on loop turnover boundary; also changed the loop turnaround strategy, now honoring already cached periods. - A race-condition has been mitigated in the audio-buffer thread, that was exposed and lead to sudden application freezing upon changing some composite audio clip commands. - Take absolute audio peak values only, making peak files a little bit shorter and hopefully faster to load and draw as waveforms. Ah, never's too late to wish you all a Happy New Year! Cheers && Enjoy -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[LAA] wcnt-1.26-pre

by james jwm-art net

Pre-release of Wav Composer Not Toilet 1.26 wcnt is a not-real-time commandline text-file-based modular synth/sequencer/sampler for GNU/Linux to generate WAV audio files. Download from: https://sourceforge.net/project/showfiles.php?group_id=76646&package_id=256… Website: http://wcnt.sourceforge.net -------------------------------------------------------------------------- This is the second release building up to wcnt-1.26 Since wcnt-1.25.5, the program has undergone many important changes. * libsndfile: the audio file IO lib from mega-nerd.com allows wcnt to read and write *WAV* audio in other data formats besides 16bit pcm. Consequently, all 16bit 'audio' inputs and outputs have been removed. *** Make sure you have it installed *** :) * LADSPA: a number of modules (9) have been created to use a select few LADSPA plugins. These provide much better filters, reverb, limiting, and compression. More might be added in future. * orbit module: impliments three orbit fractals which iterate upon a trigger, and the output of which is scaled (via an iteration test) within the -1.0 to +1.0 range. * adsr_scaler data object: allows indivdual sections of previously defined adsr modules to be scaled on the time axis. it's quick and easy. * improved command line option handling: help describing the command line options. several new options such as --dont-run and --no-title. module help now lists the modules sorted into three alphabetical collumns to make life easier. * many memory leaks plugged, and numerous operational bugs squashed. * no more -ffast_math compiler optimizations causing dodgy calculations. * removed sine_wave and tri_wave modules altogether. * wave module: a new easy-to-use module for quickly generating sine, triangle, and sawtooth waveforms and a number of variations of these outputting in the 0.0 to +1.0 range (instead of -1.0 to +1.0). * wave_phase module: comes close to the old sine_wave and triangle_wave implimentations. seperate phase trigger and phase_step inputs, and seperate phase_step input for a shaping waveform. improved algorythm means it's more likely to do what it's meant to :). new parameter to invert every other phase (or every other partial phase etc), combined with shaping (ie multiplication of two waveforms) allows a greater variety of waveforms to be created. * dc_filter and rms modules: no longer do their calculations in such an extremely deffective manner. * deg_size type inputs and outputs renamed to the far more sensible phase_step type. * constant_freq and constant_note: two new constant modules which output translations of their parameter, so they're independant of the sample rate unlike doing the same thing with the constant module. * balance module: this is the modifier module renamed to show what it actually does: balance two signals. * modifier module: does something much more interesting than balance two signals - ie combining two waveforms to create a third. * many code changes and improvments. -------------------------------------------------------------------------- ***** Please note the online help at wcnt.sf.net is now out of date. I've begun working on inline help, the beginnings of which are included as a number of text files. The text files provide short descriptions and guidlines on the usages of individual modules. ***** All your old .wc files will now be broken with this version. Sorry - things change as I slowly learn. -------------------------------------------------------------------------- Download from: https://sourceforge.net/project/showfiles.php?group_id=76646&package_id=256… Website: http://wcnt.sourceforge.net best regards, james jwm-art net
