Remix 0.2.4 Release ------------------- Remix is an audio sequencing and mixing library that provides a multichannel, sparse audio data container (streams), a structured mixing abstraction (decks), and widely useful means of generating control data (via envelopes) and of caching audio data. This release is available as a source tarball at: http://www.metadecks.org/software/remix/download/remix-0.2.4.tar.gz New in this release =================== This is a maintenance release, cleaning up various issues discovered since version 0.2.3, which was released in 2004. The web page for Remix remains at: http://www.metadecks.org/software/remix/ Revision control for Remix source code has moved to git, hosted at github: https://github.com/kfish/remix Details ======= This release contains the following changes since version 0.2.3: Conrad Parker (47): Initial revision removed auto-generated latex dox removed auto-generated html files updated cleanup in Makefile.am *** empty log message *** removed Makefile.ins from cvs! updated to bambam tree ;) removed autogenerated Makefile.in updated configure.ac removed autogenerated added autogoat added remix_compat.h update ALSA compatability, declare ALSA_PCM_OLD_HW_PARAMS_API fix compile warning in remix_squaretone.c libremix: remove CVSROOT, move old cvs trunk into libremix/trunk upgrade tests harness to use automake TESTS and nicer INFO/WARN/FAIL macros remove configure from repository remove all the ALSA code update ACKNOWLEDGEMENTS to use the project name Remix not Axel :) add a noop test, clean up tests/Makefile.am add optional testing under valgrind (./configure --enable-valgrind-testing) get rid of memory leak in allocation of channelset_defaults get rid of leak in plugin loading (was not calling closedir() on plugin dirs) add a destroy method to the plugin structure, to allow plugin handles (not just instances) to be destroyed conditional compile if libsndfile is not present remove commas from end of enums (compile warning) bugfix for libsndfile configure check update config.h.in add build info (with valgrind command line) to configure output formatting, comments update my email address throughout fix a straggling old name instance update autogen.sh to allow out-of-tree builds specify srcdir for demo wav files update config.h.in configure: AM_PROG_CC_C_O for per-target cflags configure: set valgrind --num-callers to 50 (max) ladspa: closedir after scanning plugins add TODO file with tasks and ideas for improvement.

[ANN] jack_capture V0.9.58

by Kjetil Matheussen

jack_capture ============ jack_capture is a program for recording soundfiles with jack. The default operation of the program is executed by writing "jack_capture" in the terminal without any extra command line options: $ jack_capture ...which will record what you hear in your loudspeakers into a stereo wav file. 0.9.54 -> 0.9.58: * Created git repository for jack_capture at github: https://github.com/kmatheussen/jack_capture * Removed jack_capture_gui2 from target list. The source is still included with jack_capture, and can be compiled up by writing "make jack_capture_gui2", but I'm not willing to maintain it. Please use at your own risk. If anyone wants to distribute it and maintain it as a program separate from jack_capture, please do so. * Fix bug which in theory could cause malformed sound data to be sent to stdout. * Fix bug that caused durations lower than 2^31 seconds to fail. (Caused by a function returning int instead of int64_t). Thanks to Dan Muresan for pointing out the bug. * Added the "-daemon" switch patch from Dan Muresan. If the "-daemon" switch is enabled, jack_capture will not read from stdin. * Added the "-manual-connections" switch. jack_capture will not connect any ports for you when this is enabled. (Perhaps even more important: it will not disconnect any ports for you either) * Applied gcc 4.5 linking order fix from Alessio Treglia. * Changed march=native to mtune=native * Fix for possible error when trying to connect to a non-existing port. * Don't hardcode meterbridge path during compilation. Thanks to Adrian Knoth for fix. * Avoid killing random process at exit in case meterbridge couldn't be started.

Announcing synthclone-0.1.0

by Devin Anderson

After almost two years, I'm happy to announce that a new version of `synthclone` is available for download! The new version of `synthclone` is a complete departure from the utility application I wrote two years ago on a rainy weekend. Here are the most important changes: - `synthclone` is now a Qt-based application with a table interface that allows a user to configure sample times, release times, notes, velocity values, aftertouch, channel pressure, and MIDI control changes on a zone-by-zone basis. You can tweak the parameters and audition samples until you're satisfied with the samples you've acquired. - The application is now session-based. Sessions can be saved and restored. - `synthclone` comes with `libsynthclone`, a plugin API that allows developers to write plugins that can interact with and extend the application. Developers can add components to `synthclone`, including sampler components (for sending MIDI and acquiring audio data), effect components (for altering audio data), and target components (for writing patches that work with software that can play back sample-based instruments). In addition, the API allows plugins to do almost anything that the application itself can do. All changes to the session are accessible via the observer pattern (using Qt signals and slots), allowing plugins to easily sync to session changes. - `synthclone` is distributed with several plugins: 1.) libsynthclone_hydrogen - Builds Hydrogen drumkits. 2.) libsynthclone_jack - Sampling via the JACK Audio Connection Kit. Includes JACK Session support. 3.) libsynthclone_sfz - Builds SFZ instruments. 4.) libsynthclone_trimmer - Trims "silence" off of the start and end of acquired samples. 5.) libsynthclone_zonegenerator - Generates zone data for acquiring samples. - The application can write multiple targets (i.e. Hydrogen and SFZ) in one session. No need to restart `synthclone` and wait while samples are reacquired. The new version of `synthclone` is available at: http://synthclone.googlecode.com/ This is an alpha release. Please report bugs using the issue tracker: http://code.google.com/p/synthclone/issues/list If you like `synthclone` and have ideas that can make it better and/or want to keep up with its progress, join the users group: http://groups.google.com/group/synthclone-users If you're a developer and want to write plugins for `synthclone` or contribute to the application itself, join the development group: http://groups.google.com/group/synthclone-development On a closing note, I'd like to thank Peter L. Jones for patiently answering my questions about the SFZ format. With his help, I was able to understand far more about the SFZ format than I ever could using the official documentation. Thanks, Peter! -- Devin Anderson devin (at) charityfinders (dot) com CharityFinders - http://www.charityfinders.com/ synthclone - http://synthclone.googlecode.com/
