guitarix is a simple Linux Rock Guitar amplifier and is designed to achieve nice thrash/metal/rock/blues guitar sounds. guitarix uses the Jack Audio Connection Kit as its audio backend and brings in one input and two output ports to the jack audio graph. guitarix provide a jack midi input port to connect a midi controller (midi learn) and a (3 channel) jack midi output port, feed by a (scalable) mix of the tuner and a beat-detector. Release 0.08.0 comes with a bunch of major changes : * new portmap window * new BiQuad Filter * new Moog Filter * new Flanger * new post processing tube3 * new two 10 band parametric EQ's * new oversample mode selector(1x -8x) * fix some bugs in midi out * reworked tuner interface (show frequency(hz)) * new configure options (see ./waf --help for more info) have fun ________________________________________________________________________ guitarix is licensed under the GPL. Project page with screenshots: http://guitarix.sourceforge.net/ download: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum here: http://sourceforge.net/apps/phpbb/guitarix/ ________________________________________________________________________ For capture, guitarix uses the great 'jack_capture' (version >= 0.9.30) written by Kjetil S. Matheussen. If you don't have it installed, you can look here: http://old.notam02.no/arkiv/src/?M=D For extra Impulse Responses, guitarix uses the zita-convolver library, and, for up/down sampling we use zita-resampler, both written by Fons Adriaensen. If you don't have it installed, get it here: http://www.kokkinizita.net/linuxaudio/index.html We use the marvellous faust compiler to build the amp and effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ For faust users : All used Faust dsp files are included in /guitarix/src/faust, the resulting cc files are in /guitarix/src/faust-cc The tools we use to convert (post-processing and plot) the resulting faust cpp files to the needed include format, stay in the /guitarix/tools directory. ________________________________________________________________________ regards Hermann Meyer, James Warden, Andreas Degert

MMA 1.6 has been released

by Bob van der Poel

A stable release, version 1.6, of MMA--Musical MIDI Accompaniment is available for downloading. In addition to a number of bug fixes and optimizations, MMA now features: - A new track, the Plectrum. This can generate a realistic MIDI guitar. Getting a realistic guitar sound using MIDI has been notoriously difficult as calculating the notes in each chord and strumming patterns can be very tricky. Now the MMA PLECTRUM pattern takes care of most of this for you so all you have to do is to enter the chords names and how when you want each string to be strummed or plucked. An example is available at: http://www.mellowood.ca/mma/examples.html#plectrum - Improved chord placement anywhere in a bar. - Added MidiCopyright, MidiCue and MidiText commands. - Improved lyric generation for Karaoke mode. MMA is a accompaniment generator -- it creates midi tracks for a soloist to perform with. User supplied files contain pattern selections, chords, and MMA directives. For full details please visit: http://www.mellowood.ca/mma/ If you have any questions or comments, please send them to: bob(a)mellowood.ca -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Rubber Band Library v1.5.0 now available

by Chris Cannam

Rubber Band Library v1.5.0 is now available. http://breakfastquay.com/rubberband/ This release adds a key-frame mapping facility for managing variable stretch ratios within a single offline time-stretch pass, plus a more reliable transient detection mode for soft instruments and band-limited transient detectors to improve performance with compressed or lower-quality material. It is source and binary backward compatible with v1.4, though code written for v1.5.0 may not work with v1.4 (the new release adds one new function and one new enum). Chris

by Ivica Ico Bukvic

Apologies for cross-posting... Dear Colleagues and fellow computer music enthusiasts, On May 30th 1pm-7pm EST @ NYC Resistor L2Ork will hold a one-day workshop on building Linux-based laptop orchestra and unique opportunities such an ensemble brings about. Synopsis: L2Ork is an ultra-affordable tool for handling administrative logistics associated with starting a new Linux-based laptop orchestra using exclusively free software and cost-efficient hardware. The workshop will cover general issues in regards to starting a Linux-based laptop orchestra, as well as provide an opportunity for the workshop participants to engage in writing for L2Ork. The workshop will also cover L2Ork's latest initiative to bridge STEM (Science, Technology, Engineering and Math) and Arts in K-12 education and funding opportunities such a project may bring about. Participants will learn about: * administrative and logistical prerequisites for starting a Linux-based laptop orchestra * design considerations in designing and building adequate infrastructure (speakers, soundcard, system configuration and optimization) * streamlining Linux platform * optimizing Pure-Data software for GUI-based networked performances * ensuing creative opportunities of a networked laptop orchestra * design strategies and standards developed for writing pieces for the L2Ork ensemble * education-based opportunities attained through L2Ork's ultra-affordable infrastructure * logistical considerations in building GUIs for a diverse group of performers with widely varying amount of musical training and experience * wiimote strategies for an ensemble-oriented performance * strategies for incorporating soloists into the L2Ork ensemble Participants will be given access to: * all L2Ork's resources, including custom code and Pure-Data abstractions designed specifically for the orchestra and its input devices * customized Pure-Data software platform with performance, editor, and GUI enhancements * access to software repository containing optimized Linux kernel and supporting software as well as turnkey Linux setup containing an entire hard-drive image of the L2Ork Linux system * detailed list of parts necessary to build L2Ork-compatible ~$250 hemispherical speakers and a ~$750/seat turnkey setup including a laptop, external soundcard, wiimote & nunchuk, headset, cables and accessories, and a custom hemispherical speaker. All participants will be also given an opportunity to interact with L2Ork members (performers and researchers alike) as well as submit their own works for programming consideration by the L2Ork ensemble. For a more detailed overview and registration info please visit: http://icmc-workshop-l2ork.eventbrite.com/ NB: please note that the times listed on the aforesaid site are in Pacific Time. For additional info on L2Ork, please visit http://l2ork.music.vt.edu. Should you happen to have any questions, suggestions or concerns, please do not hesitate to contact me.

NASPRO 0.2.0 released

by Stefano D'Angelo

Hello everybody, I'm pleased to announce the release of NASPRO 0.2.0, which includes: * NASPRO core: a tiny convenience library containing useful code to implement LV2 dynamic manifest plugins and especially bridges from other APIs to LV2; * NASPRO bridges bad: a collection of <API>-to-LV2 bridges which work fine, but do not completely support the original APIs; * Permafrost: a DSP language designed with physics-based modeling in mind - the compiler produces RDF/Turtle data and C code implementing LV2 plugins. It should work on all POSIX-compliant platforms on LV2 hosts which support the LV2 dynamic manifest extension (zynjacku >= 5 or SLV2 > 0.6.6 based hosts with SLV2 compiled with the --dyn-manifest option). The bridged APIs in this release are LADSPA 1.1 (+ LRDF) and DSSI 1.0; the LADSPA bridge supports almost all LADSPA/LRDF features (run_adding() and LRDF presets are missing), while the DSSI bridge is still lacking (no GUI, no MIDI programs, no run_multiple_synth*() support). Permafrost, instead, is a very experimental thing, so there is no official documentation (but you can easily guess the syntax by looking at the provided examples) and backwards compatibility is not taken seriously in the next releases. Enjoy, Stefano Website: http://naspro.atheme.org
