Hi Everyone, This mail announces a new release of Nama,[1] a digital audio workstation. By using Kai Vehmanen++'s Ecasound[2] audio processing engine, Nama can provide DAW functionality (tracks, buses, effects, parameter controllers, sends, inserts, marks, fades and regions) in a small, well-tested codebase. The optional GUI resembles a simple hard disk recorder. More advanced functions are available at the command prompt. New with v1.107: + Optionally use git for managing project state (save/get commands work with branches instead of files) + Automatic ogg/mp3 encoding of mixdown files + Effect chains and profiles store inserts as well as effects + Shell script hooks for external track record setup and cleanup For examples of music recorded with Nama, see Julien Claassen's website.[3] Notable features ---------------- Audio editing + Nondestructive + Track caching (freezing/unfreezing) + Mastering mode based on Jamin + Pop up Audacity or MHWaveedit for waveform viewing/editing + LADSPA, LV2 and Ecasound effects and controllers + JACK or ALSA I/O User interface + Searchable help for commands and effects + Command language has simple syntax and autocompletion + Templates for reusing effects, inserts, tracks and projects + User defined commands, scripts and JACK port autoconnect lists + Prompt handles Ecasound, Midish[5] and internal commands, shell commands or Perl code + Commands can address multiple tracks or effects + Full documentation Stability + Based on Kai Vehmanen's mature audio processing engine + Signal processing network can be verified by inspecting the Ecasound chain setup + Test suite verifies core functions Hacking + Extensive logging and debugging aids + Small well-structured codebase (approx. 14k lines in 60 files) + Easy to build and hack, no compiling required Installation ------------ For most users, cpanm Audio::Nama should be enough to install it. (Debian packaging will follow.) See "man nama" for documentation or type "help" at the command prompt. For access to the latest fixes and feature, you can build Nama from github.[4] In the pipeline --------------- + JACK latency integration with latency compensation among arms of the internal signal network + Positions stored as samples + Marks that move with their associated track + Edits to replace a note or phrase Further down the road --------------------- + Merging of project branches + Use an external program (MHWaveedit?) to manage transport, define regions + A/B comparisons + OSC interface + Additional MIDI capabilities [1] http://freeshell.de/~bolangi/nama http://search.cpan.org/dist/Audio-Nama/ http://www.freelists.org/list/nama [2] http://eca.cx/ecasound/ [3] http://juliencoder.de/nama/ [4] http://github.com/bolangi/nama [5] http://www.midish.org/ -- Joel Roth

I'm proud to announce the release of guitarix2-0.26.0 Guitarix is a mono tube amplifier simulation for jack, with additional mono/stereo effect racks which can be filled with some in-build effects as well as with external LADSPA plugins. Download from http://sourceforge.net/projects/guitarix/ This release is mostly related to the LV2 port of guitarix modules. With this release we remove the previous released GxAmplifier LV2 versions and replace them with the new GxAmplifier-X module, which include the complete guitarix amp head with all tube, tonestack and cabinet selectors. It comes as Mono and as well as Stereo version. Additional some completely new Amp models by our new Team member Steve Poskitt been included. A couple of additional effect modules been ported to LV2. See the list below. (FOR DEVELOPERS AND MAINTAINERS) For guitarix main we have included some new (and fix some old) configure options required by Gentoo proaudio overlay and Fedora maintainers. Additional there are some new configure options mostly related to the new LV2 port which may interest the one or the other of you. Check them out with ./waf –help As usual, all used faust dsp files been included within the source, as well all our tools we us to create and port them to LV2. All LV2 plugs comes with GUI's based on our included libgxwmm, a additional Gtkmm toolkit library. Special thanks to David Robillard and Harry van Haaren for there open ears on the LV2 mailing list. Included LV2 modules: * GxAmplifier-X * GxAmplifier-Stereo-X * GxAutoWah * GxWah * GxBooster * GxChorus-Stereo * GxCompressor * GxDelay-Stereo * GxEcho-Stereo * GxEchoCat * GxExpander * GxFlanger * GxPhaser * GxRedeye Chump * GxRedeye Big Chump * GxRedeye Vibro Chump * GxReverb-Stereo * Gx Alembic Mono * Gx Studio Preamp Stereo * GxTiltTone * GxTremolo * GxTubeScreamer * GxTubeDelay * GxTubeTremelo * GxTubeVibrato * GxZita_rev1-Stereo Please refer to our project page for more information: http://guitarix.sourceforge.net/ download site: http://sourceforge.net/projects/guitarix/ have fun guitarix development team

[LAA] Python Non-Session-Manager Client Module (version 0.1)

by Nils Gey

Dear Developers, I've written a convenience interface to implement Non Session Management as fast and easy as possible in Python 3 applications. It is no magic programming at all, but it makes things just that tiny bit easier that is required to actually implement something, and not only plan it. The real work is to follow the rules of a managed system (see http://non.tuxfamily.org/nsm/API.html ). So implementing the technical side should be a no-brainer to let you focus on the actual task. pynsmclient is open source under the GPL3 or later and can be found on my github page so you can start using it right away. https://github.com/nilsgey/pynsmclient I also have written a short article in my blog about that topic http://nilsgey.de/?id=24 Greetings, Nils

[LAA] [ALPHA] ladspa.m.*

by Florian Paul Schmidt

Hi, after a somewhat productive weekend I'm happy to announce some alpha quality software (i.e. bug ridden, not feature complete) for your consideration and feedback :) But: release early, release often XD I went a little overboard with modularization and separation of concerns, so in the end it became four packages (with possibly one more in the future - a LV2 plugin to load the synths/instruments). Documentation is also very much lacking, but each package contains at lease a single example file to illustrate the usage. * ladspa.m - https://github.com/fps/ladspa.m ladspa.m is a header only c++ library to build and run general synthesis graphs made up out of LADSPA plugins. The interface is kept deliberately kept simple and unsafe, as it is expected that one uses higher level tools to build these synthesis graphs (e.g. using a library on top op ladspa.m.swig or ladspa.m.proto). * ladspa.m.swig - https://github.com/fps/ladspa.m.swig ladspa.m.swig are SWIG generated python bindings for ladspa.m. This allows building and running general synthesis graphs made up of LADSPA plugins from within python. This requires ladspa.m. NOTE: I just saw that the swig interface definition lacks the ability to connect outside buffers onto plugin ports. This will be fixed in the next few days.. * ladspa.m.proto - https://github.com/fps/ladspa.m.proto ladspa.m.proto contains google protobuf definitions for general synthesis graphs made up of LADSPA plugins. It also contains a definition for an instrument file format. This library does not depend on either of the two above. It becomes useful with the last package (ladspa.m.jack) and possibly in the future with an LV2 plugin to load and run these (to be announced when done). The python bindings generated for ladspa.m.proto can be used to generate synth and instrument files that can be loaded by ladspa.m.jack. The instrument file definition allows for polyphony while at the same time putting no constraints on the inner structure of the instrument (each voice is made up out of plugins, they can be identical or not between all voices).. An example is included which defines a simple sawtooth instrument with exponential envelopes and with 5 identical voices except for a different delay setting on each voice. https://github.com/fps/ladspa.m.proto/blob/master/example_instrument.py Pipe its output into a file called e.g. instrument.pb. This you can then load into ladspa.m.jack.instrument. Here's a little example of the generated instrument file loaded into ladspa.m.jack.instrument and playing a little 120bpm loop (from ardour3) with it: https://soundcloud.com/fps-2/t-m This also highlights the need for a higher level interface on top of it to ease the process.. * ladspa.m.jack - https://github.com/fps/ladspa.m.jack ladspa.m.jack is a library which allows loading ladspa.m.proto synth and instrument definition files into jack hosts that are provided as example clients. ladspa.m.jack.synth allows loading a synth definition file and run it in the jack graph. ladspa.m.jack.instrument allows loading an instrument definition file and provides a midi in port which allows playing the synth. But like I said this is all ALPHA software and I just announce it because someone else might have fun with it. Please report all issues that you find either per email to me, on LAD or LAU or on the issue trackers of the github projects.. Have fun, Flo -- Florian Paul Schmidt http://fps.io
