[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.

[ANN] VMPK & FluidSynth 0.1.0 for Meego Harmattan

by Pedro Lopez-Cabanillas

Hi, VMPK & FluidSynth is a MeeGo Harmattan application for Nokia N9/N950 smartphones. It contains a QML based VMPK user interface bundled with FluidSynth for sound generation. Several enhancements have been included since the beta announced in August. * Controllers, Bender, and Velocity values can be optionally controlled by the accelerometer. * Internationalization. This version includes translations to Spanish, Russian (thanks to Serguey Basalaev) and Czech (thanks to Pavel Fric). * Inverted color theme. This dark color combination consumes less power, enabling longer battery life. * Latest FluidSynth included. Binary packages available at the OVI Store http://store.ovi.com/content/210572 Sources at SourceForge.net http://sourceforge.net/projects/vmpk/files/vmpkn9/ Screenshots in this blog post http://midi-clorianos.blogspot.com/2011/10/vmpk-fluidsynth-010-released.html Regards, Pedro

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/
