SLV2 is a library to make the use of LV2 plugins as simple as possible for applications. This is a bugfix release. 0.6.1 failed to recognize any LV2 features. Upgrading is strongly recommended. Let us all just pretend that 0.6.1 never existed. 0.6.1 is not to be invited to any parties. It will sit alone for the holidays, cursing haste and drinking alone. Changes this release: - Fix feature detection - Add --no-jack configure flag for building without jack dependency (i.e. don't build jack clients; slv2 itself never depends on jack) <http://drobilla.net/software/slv2> Happy Hacking, -dr

[ANN] zynjacku version 2 released

by Nedko Arnaudov

In this release: * zynjacku codebase updated to the latest state of LV2 art. Especially, event MIDI port synths are now supported. * The tarball now contains lv2rack - a host for LV2 effect plugins. * Saving/restoring of presets. Does not work for dynparam plugins yet. * LASH support (autodetected at runtime). * Lot of general fixes that should make zynjacku more usable. I would like to thank Krzysztof Foltman for adding support for some LV2 extensions and Martin Raspaud for helping with slv2 compatibility during my LADI quest. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins. You need slv2 library, Pyhton bindings for PATH and lv2dynparam host library to compile zynjacku tarball.

[ANN] JACK 0.115.6 + D-Bus

by Nedko Arnaudov

Tarball containing D-Bus patched jack 0.115.6 is available here: http://nedko.arnaudov.name/soft/jack/dbus/ http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… D-Bus modifications add optional autodetected support for the D-Bus based server control system. D-Bus is object model that provides IPC mechanism. D-Bus supports autoactivation of objects, thus making it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. * Simplified single thread model for control and monitor applications. Various D-Bus language bindings make it trivial to write control and monitor applications using scripting languages like Python, Ruby, Perl, etc.. * JACK has log file (~/.log/jack/jackdbus.log) that is available for inspection even when autoactivation happens because of first JACK application is launched. * There is real configuration file used to persist settings that can be manipulated through configuration interface of JACK D-Bus object. * Improved graph inspection and control mechanism. JACK graph is versioned. Connections, ports and clients have unique (monotonically increasing) numeric IDs. * High level abstraction of JACK settings. Allows applications that can configure JACK to expose parameters that were not known at compile (or tarball release) time. Currently there are some minor differences between jack1 jackdbus and jack2 jackdbus: * There is no parameter constraints support (no enums and no ranges) * No get client pid function (probably affects lash) * Settings file (in ~/.config/jack/) is conf-jack1.xml instead of conf.xml, because jack1 and jack2 settings and not really compatible. When configured with D-Bus support, jack_control is installed. jack_control is simple commandline interface for jackdbus. Other tools that can communicate with JACK through D-Bus: * LADItools (tray icon, configuration, etc.) * Patchage (and lpatchage too) * LASH 0.6.x (may not work properly with jack1 jackdbus implementation) -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Calf Audio Plugin Pack 0.0.17 released

by Krzysztof Foltman

The version 0.0.17 of Calf Audio Plugin Pack has been released. This is the first release after Calf team gained a second plugin developer, Thor Harald Johansen. Calf is a set of open source instruments and effects for digital audio workstations. Multiple plugin interfaces are supported: LV2, DSSI, JACK (standalone application) and, for slightly outdated hosts, LADSPA. The plugins are equipped with GTK+-based graphical user interfaces. Some of these interfaces contain live (and accurate) graphs for easier control over parameters. Unfortunately, that functionality is only available in standalone version, or LV2 versions when used with Ardour 2.7, Zynjacku or LV2Rack. Calf contains the following effects and instruments: - (new in 0.0.17) smooth-sounding dynamic compressor - (new in 0.0.16) multi-tap chorus - organ-like polyphonic synthesizer - a simple monophonic subtractive synthesizer - tape-like delay - reverb - multimode filter with parameter smoothing (inertia) - flanger - phaser Example screenshots: http://calf.sf.net/multichorus2.png http://calf.sf.net/compressor2.png Recent versions of Calf also contain a set of about 50 plugins for modular LV2 hosts (like Dave Robillard's Ingen). Logic gates and flip-flops, basic filters, oscillators, multiplexers, arithmetic operators - and other building blocks for creating interesting patches. The source version of Calf can be downloaded from the following page: http://sourceforge.net/project/showfiles.php?group_id=211458 Calf home page: http://calf.sf.net/ The Calf Team

Strasheela 0.9.7 released

by Torsten Anders

Dear all, Strasheela is a highly expressive constraint-based music composition system. Users declaratively state a music theory and the computer generates music which complies with this theory. A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns). Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). Results can be output into various formats including MIDI, Lilypond, and Csound. This release improves Strasheela's export of sound synthesis formats. For example, expressive timing of scores can be defined by time shift functions. Predefined MIDI file export now supports also non-note events like continuous controllers (e.g., pitch bend, aftertouch, CC) and a global tempo curve. Additional examples have been added, and further extensions and bug fixes have been made as well. For more information on Strasheela, please visit http://strasheela.sourceforge.net/ Changes are described at http://strasheela.sourceforge.net/strasheela/doc/Changes.html This release can be downloaded from: https://sourceforge.net/project/showfiles.php?group_id=167225 Best Torsten -- Torsten Anders Interdisciplinary Centre for Computer Music Research University of Plymouth Office: +44-1752-586219 Private: +44-1752-558917 http://strasheela.sourceforge.net http://www.torsten-anders.de

PianoBooster version 0.5.0 has just been released

by Louis B.

PianoBooster version 0.5.0 has just been released, this is the first ever release of PianoBooster. If you dabble in music and have a Midi Piano keyboard lying around then give PianoBooster a go as it actually makes sight reading music fun!!!!! To see what it is all about take a look at the screen shot: http://pianobooster.sourceforge.net/images/LinuxScreenShot.png First choose a MIDI file (the Easy Play Beethoven is a good one -- see the download page for where this can be found) then select which part that you want to play along with (e.g. the piano part or the strings part etc). Then select the "left" hand or the "right" hand or if you are feeling really brave choose "both hands" and try to play along. The "Follow You" mode make it really easy to sight read the scrolling notes as the whole accompaniment will stop and wait for you to find and play the right notes. The accuracy bar monitors how well you are playing. If you are skilled enough the accuracy bar will go right to the end and then turn blue. But every time you are too slow or playing out of time, then the accuracy bar slips back a bit. You can watch a video of it in action on YouTube: http://uk.youtube.com/watch?v=7YaDllVreuM Piano Booster 0.5.0 is released under the GPL and is available at SourceForge on this page: http://pianobooster.sourceforge.net/download.html L o u i s B a r m a n

jackctlmmc (kinda sorta) release

by Alex Montgomery

Hello, We'd like to announce a new release of jackctlmmc, a command line tool for driving JACK transport using Midi Machine Code that you can download here: https://sourceforge.net/project/showfiles.php?group_id=245788 or get the code here: http://repo.or.cz/w/jackctlmmc.git The program is still in its infancy but it should work for most MMC devices. It currently supports the following MMC commands: Play / Deferred Play - start transport Stop - stop transport Rewind - go to time 0 Goto: go to the specified SMPTE time It's a pretty simple command line utility for now, but we'll be working on a QT front end soon. To use jackctlmmc: 1) start the program on the command line: ./jackctlmmc -f <your device's SMPTE frame rate> -t <jitter tolerance in milliseconds> You can also specify -v if you want it to output messages in the console for all MMC commands it's handling, which is useful for testing. 2) connect your midi port to jackctlmmc using either aconnect or JACK's connect (you will have to specify JACK's midi driver as "seq" if you want to connect using JACK). For the goto command to work, jackctlmmc needs to know your device frame rate which you can specify with -f, or use the default 30 fps. Some MMC devices (like my BR900CD 8-track) are awfully spammy with their goto messages, so we've implemented a jitter tolerance (specified in milliseconds on the command line with -t, defaulting to 50) so jackctlmmc will ignore goto commands that are already close enough to the current JACK transport time. There's still a lot of work to do on the application, but we've been getting emails asking for progress updates, so we decided to do a quick release now. Hopefully it's useful to people other than ourselves. -- Alex
