Happy new year.
On behalf of the entire Rivendell development team, I'm pleased to announce
the release of Rivendell v1.2.1. Rivendell is a full-featured radio
automation system targeted for use in professional broadcast environments. It
is available under the GNU General Public License. Changes in this release
include (from the NEWS file):
*** snip snip ***
This is a maintenance release of Rivendell. The following issues have been
Several errors in handling metadata values in file imports have been
corrected, and support for detecting Ogg metadata tags added.
Fixed a bug in RDAirPlay that could cause a segfault when loading a log
over an existing log.
This version of Rivendell uses database schema version 170, and will
automatically upgrade any earlier versions. To see the current schema
version prior to upgrade, see RDAdmin->SystemInfo.
As always, be sure to run RDAdmin immediately after upgrading to allow
any necessary changes to the database schema to be applied.

Renoise RC2 contains a new demo song, tweaks and bugfixes. This is the last version before Renoise 2.0 goes gold.
This version is "free as in beer" and looking for Linux testers outside the registered user base.
Renoise has a different approach to making music compared to conventional sequencers, called Tracking. Tracking comes from the demoscene that pushes technical limits to show off coding skills, art, and music beyond what is thought possible.
Renoise was originally written from code by the late Arguru. In 2000 the new Renoise team started to take tracking software into a new standard of quality, enabling users to make music on par with mainstream sequencers, while still keeping the proven design principles of years gone by.
With Renoise 2.0 a generation of oldschool trackers and contemporary musicians looking for something "different" have reason to celebrate.
Show them the way! Add maps and directions to your party invites.
Apologies for cross-posting.
Forwind invites musicians/software developers/artists who write custom audio
software to submit both a piece of music created with the software and the
software itself for inclusion in an audio and software compilation due to be
released mid 2009.
This compilation will strive to present both the software and audio on an
equal footing. Design of the end package will be in the very capable hands
of Paul Finn from Fitzroy & Finn (www.fitzroyandfinn.co.uk). The intentions
are for this to be a substantial physical release (Book, double CD etc -
details have yet to be finalized.)
Software may but not necessarily need to include patches/code from
PureData/Max MSP, Supercollider, Chuck, CSound, Faust, CLM, Snd-Rt, VSTs,
Ladspa's, Processing, bespoke sound apps (C/C++, python, ruby, fortran,
assembly!) et al ...
Please send submissions to

Merry season greetings!
After a very long quarantine period, and while after the last Flirty
Ditz romance, this pet has calmly bumped a few more steps ahead. Please
welcome, my Christmas present to y'all,
Qtractor 0.3.0 (fluffy doll) has been released!
Same old intro follows:
Qtractor is an audio/MIDI multi-track sequencer application, written in
C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its
main infrastructures and Linux as native and exclusive platform.
Specially suited to the lone-wolf composer, arranger and (re)creative
music-maker personal home-studio, it still hopes to evolve as a fairly
featured desktop audio/MIDI workstation or at least, a prototypical part
of it ;)
* Paste-Repeat command. (NEW)
* Punch in/out recording. (NEW)
* Session/project template support. (NEW)
* Current track auto-monitoring. (NEW)
* MIDI buses now supporting multi-timbral instrument plug-ins. (NEW)
* Individual clip gain/volume, normalize and audio/MIDI file export. (NEW)
* Copy/paste to desktop environment clipboard. (NEW)
* and many, many fixes and new bugs ;)

- user manual
Weblog (think upstream support):
Qtractor is free, open-source software, distributed under the terms of
the GNU General Public License (GPL) version 2 or later.
- Multi-track audio and MIDI sequencing and recording.
- Developed on pure Qt4 C++ application framework (no Qt3 nor KDE
- Uses JACK for audio and ALSA sequencer for MIDI as multimedia
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis), MP3 (via libmad,
playback only), WAV, FLAC, AIFF and many, many more (via libsndfile).
- Standard MIDI files support (SMF format 0 and 1).
- Non-destructive, non-linear editing.
- Unlimited number of tracks per session/project.
- Unlimited number of overlapping clips per track.
- XML encoded session/project description file.
- Point-and-click, multi-select, drag-and-drop interaction (drag, move,
drop, cut, copy, paste, delete, split)
- Unlimited undo/redo.
- Built-in mixer and monitor controls.
- Built-in connection patchbay control and persistence (a-la QjackCtl).
- LADSPA, DSSI and native VST plug-ins support.
- Unlimited number of plug-ins per track or bus.
- Plug-in presets, programs and chunk/configurations support.
- Audio/MIDI clip fade-in/out (linear, quadratic, cubic).
- Audio/MIDI clip gain/volume, normalize and export.
- Audio clip time-stretching (WSOLA-like or via librubberband),
pitch-shifting (also via librubberband) and seamless sample-rate
conversion (via libsamplerate).
- Audio/MIDI track export (mix-down, merge).
- Audio/MIDI metronome bar/beat clicks.
- MIDI clip editor (matrix/piano roll).
- MIDI instrument definitions (a-la Cakewalk(tm))

- Almost complete rewrite of the plugin configuration and parameter
- MIDI bank/program selection is now taken into account on plugins
initialization and replication.
- Fixed initial parameter values for native VST plugins.
- Track form plugin lists are now properly (re)initialized when track
- Generic plugin forms now have the option to show/hide the parameter
widgets through the new "Params" button.
- New auto-monitor toggle option (menu Track/Auto Monitor): the current
selected track is now set on monitor and MIDI channel omni-mode
automagically, as a convenient workflow feature (kindly suggested by
- MIDI clip editor Tools menu is not disabled anymore when there's no
selection, drop-down menu items are instead.
- Make all recorded clips to honor either the punch-out or play-head
accumulated position; resolve all pending MIDI sequence note events on
- Major silent move: audio plugins chain are now applied in a
pre-fader/meter basis as is usually implied from the mixer strip layout
ie. signal flows from the top to the bottom.
- All MIDI buses may now have plugins inserted so that multi-timbral
synth/sampler plugins get driven to their fullness.
- MIDI track plugin's dedicated audio output bus may now be effective,
as it seems, good old master audio output bus was being used, no matter
- Paste-repeat command has been introduced, now allowing to replicate
and concatenate the clipboard contents over the time-line, with a given
repeat-count and optional period (see menu Edit/Paste Repeat... on the
main and MIDI clip editor windows).
- Normalize tool on MIDI clip editor got rewritten from its previous
brain dead, useless and utterly wrong operation.
- All time offsets and lengths are now zero-bar/beat based when
displayed in the BBT (bar.beat.ticks) format.
- MMC STEP gets adjusted to current snap-per-beat setting.
- Fixed broken initial buffering that was randomly crippling those audio
clips that fit integrally in cached and while on playback.
- Fix initialization of multiple instances of DSSI plugins which
implement run_multiple_synths (eg. fluidsynth-dssi), preventing an
instant crash on activation.
- Exclude deprecated VST elements from compilation.
- Export tracks dialog has new punch in/out range option.
- Somehow realized that looping and punch-recording are two mutually
exclusive states, at least until loop recording (ie. takes) gets real.
- Fixed bug #2249291 - Crash on tempo change; affecting the WSOLA based
time-stretching on all non-stereo audio clips.
- Incomplete audio peaks were being cached prematurely, fixed.
- Make way for paste/dropping items from the system clipboard over the
main track view. Cut/Copy/Paste/Delete of file items have now this
workaround fixed, wrt. Files widget keyboard shortcuts, respectively.
- Clip gain/volume propriety is now in place and reflected in audio clip
waveform drawing in particular.
- A new hideous progress bar is now lurking in the main status line, as
found convenient to display progress of the also new clip tools
(normalize, export, etc.).
- Clip normalize tool is now available (Edit/Clip/Normalise).
- Audio and MIDI clip file export is now available as a tool (see
- Punch in/out (range) recording is now in experimental shape, with
minimal settings and functionality, already accessible through the main
menus, transport toolbars and visible on main tracks view and MIDI
editors as magenta colored line markers.
- External MIDI control events for channel volume (7) and channel
panning (10) are now handled properly through session tracks.
- Session file templates make its debut with new usability option, on
whether new sessions are created based on existing template file (see
View/Options.../Display/Session/New session template; nb. session
templates are just regular session files but loaded and saved with no
media content (no clips nor files).
- Grayed/disabled palette color group fix for dark color themes.
- Implicit attempt to flush all pending notes for some, if not most
plugin instruments (eg. VSTi), on playback stop.
- Fait-divers: desktop menu file touched to openSUSE conventions.
- Internal refactoring alert: Session and Options instances are now
being redesigned as singletons, preparing to get out of the way from the
master GUI/MainForm instance.
- Clip drawing methods refactored so let the fade-in/out handles get
seen with transparency over the clip graphics content.
- Reset and continue looping even still when continue past end transport
option is not set and playback is rolling.
Hope it makes through a Happy New Year with flying colors ;)
Cheers && Enjoy!

As you may know there exists a cross-platform graphics library called SDL.
It is mainly used for games, but it is excellent for normal app's also.
Some time ago I wrote a GUI toolkit on top of SDL, called SDL-widgets.
It is far from complete, because I focussed on 2 example audio applications,
that might also be of interest for visitors of this newsgroup.
The first example app is called make-waves. It can:
- draw waveforms to the screen, modulate them by each other, you can listen
to the result,
- draw a physical model of a string or a spring that you can listen to and
animate with the mouse,
- draw and edit the harmonic spectrum of a sound,
- display the frequency curve of digital filters, that you also can plug in
The 2nd example app, wav2spectrum, can read a wave file and perform FFT
analysis on it. You can scroll through the cached waveform chunks and FFT
I tried to document the toolkit and the examples fairly well, so maybe
they have some use for others as well. You can get it from:

This is the synthesizer engine of horgand released as dssi plugin, including 28 banks of 32 sounds each one.
Sound edtion is not allowed, is only for use as sound font in your favorite sequencer.
Anyway you can create new sounds with the standalone horgand.
Thanks to all the dssi plugin authors, without their works would have never been able to do this.
Take a look in:

The 0.8 release of dssi-vst is now available.
dssi-vst is an adapter that allows users of Linux audio software to
take VST and VSTi audio effects and instrument plugins compiled for
Windows, and load them into native LADSPA or DSSI plugin hosts.
dssi-vst can also be used to run 32-bit Windows VST plugins in a
64-bit Linux host.
The main change in version 0.8 is to make building dssi-vst on 64-bit
systems much simpler.
Sonic Annotator is a utility program for batch feature extraction from
audio files. It runs Vamp audio analysis plugins on audio files and
can write the result features in a selection of formats, in particular
as RDF using the Audio Features and Event ontologies.
A somewhat experimental first public release (0.1) is now available.
For more details and for downloads, please see
Sonic Annotator was developed at the Centre for Digital Music, Queen
Mary, University of London. It was funded by the EPSRC through the
