[ANN] Qtractor 0.9.18 - A Fall'20 Release

by Rui Nuno Capela

Hi everyone,... Qtractor 0.9.18 (fall'20) is out! Change-log: - When under NSM, all top-level windows, main, mixer and connections, will always start hidden. - Plugin editors (GUIs) that are currently open on a track are now brought up as top-level windows immediately when a track is made current or highlighted (and Track / Auto Monitor is in effect). - MIDI clip editor mouse hovering effect extended to whole current note line on main view (piano-roll eye-candy++); also, the white keys on MIDI clip editor's virtual piano keyboard, are now fully highlighted. - Plugin search paths (View > Options... > Plugins > Paths) now lists all the default and actual existing paths, instead of a blank list. - Undimmed octave divider lines on the piano-roll. - Fixed potential crash on changing audio output buses channel count. - Note names display (inside note rectangles) are now an option on the MIDI clip editor (aka. piano-roll; menu View > Note Names). Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

[ANN] Vee One Suite 0.9.18 - A Fall'20 Release

by Rui Nuno Capela

Boring news ahead... Once again, the 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here released onto the wild, just for the (Northern) Fall/Autumn'20 season... Boring as hell, they still feature the same two kinds of deliverables: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Change-log: - Upstream package naming for the JACK standalone and LV2 plugin deliverables are suffixed to '-jack' and '-lv2', respectively. - Fixed note-off effectiveness when DCA is disabled (idle). (applies to <a href="#samplv1">samplv1</a> and <a href="#drumkv1">drumkv1</a> only) - White keys on the virtual piano keyboard are now fully highlighted. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later.

PSIndustrializer 0.2.7-pre1 released

by Yury Alyaev

Hi all, I have made a first preview of Power Station Industrializer v0.2.7 You can download it here: https://sourceforge.net/projects/industrializer/files/ What is new in psindustrializer-0.2.7: Improved accuracy of setting some parameters Rendering and playback can be interrupted. Playback can be retrigged at any time Both actuation and sampling nodes are made selectable (Hint: you can use this facility to generate great stereo samples. Although PSIndustrializer doesn't support direct stereo samples saving yet, you can manually save two samples with the same model and parameters, but different sampling nodes. Then map them to right and left channels and have fun!) Bugfixes As always, bugreports and feature requests are welcome! Regards, Yury.

SoundTracker 1.0.2 first pre-release

by Yury Alyaev

Hi all! Today I have finished a large amount of work: support of user actions logging in SoundTracker. This means that almost all operations can be undone / redone. Before this I have redesigned the sample editor. Although these are not all improvements scheduled for 1.0.2 release, I would like to start testing of the above two features. So I have issued the first pre-relase available as usual at https://sourceforge.net/projects/soundtracker/files/ I invite everyone to test this and send me bugreports. But I'd like to warn, that this pre-release couldn't be pretty stable and can occasionally crash. If you are familiar with gdb (GNU debugger) please compile ST with CFLAGS=-DDEBUG and after crash explore the core file with gdb and send me the backtrace. Regards, Yury.

[LAA] [LAU] Mamba - Virtual Midi keyboard for Jack Audio Connection Kit release 1.6

by Hermann Meyer

Hi Mamba release v1.6 is out Mamba is a Virtual MIDI keyboard with some extended, unique features. Virtual MIDI Keyboard Mamba comes with some predefined key-maps, qwertz, qwerty, azerty(fr) and azerty(be), but you could define your own with the included Key-map Editor as well. Beside the computer keyboard and mouse, Mamba supports jack MIDI in and ALSA (seq) MIDI in. Output goes to jack MIDI out. Every channel use it's own Colour to display the played Notes per channel. 16 Channel Live MIDI Looper: To record a loop, press "Play" and then to start recording press "Record". To stop recording press record again. Playback will start immediately. The first recorded channel will become the Master channel. This one set the time frame for all later recorded loops. For the Master Channel the recording time will be stretched/clipped to match the next full beat time point. To record a new loop, switch to a other channel, select your instrument and press "Record" again to start recording. The later recorded loops will be synced to the master loop. When the recording time extend the absolute Master loop time record will be switched off. Absolute time is not bound to the loop point, so you could record loops crossing it. You could as well stop recording by press "Record" again before the time expires. Each Channel could be cleared and re-recorded separate at any time. even when you press "Record" on a already recorded channel, it will be cleared before recording starts. You could record the connected input device or play the Keyboard itself. MIDI File player You could select a MIDI file with the File Selector. It will be loaded in the play buffer of the first channel, regardless how much channels it use. You could use then channel 2 - 16 to record your own playing into it. To play along with it you could use any channel. A loaded file will become the Master channel for the looper. To save your work just go to Menu -> "File" -> "Save MIDI file as", select the path and enter a file name. If you don't give the usual file extension Mamba will add the extension .midi befor save it. Fluidsynth When you load a Sound-font via the Menu -> "Fluidsynth" -> "Load Sound-font" Mamba will start the Fluidsynth engine and do the needed connections so that you could just play along. Menu -> "Fluidsynth" -> "Settings" will pop-up a new Window were you could select the Instrument for the channel and do settings for Fluisynth Reverb and Chorus. All your Settings will be saved on exit, so on next start you could just play along. Mamba is released under the BSD Zero Clause License license The GUI is build on libxputty - A damn tiny abstraction Layer to create X11 window/widgets with cairo surfaces https://github.com/brummer10/libxputty To build Mamba from source, the following dependencies must be meat. * libfluidsynth-dev * libc6-dev * libsmf-dev * libcairo2-dev * libx11-dev * liblo-dev * libsigc++-2.0-dev * libjack-(jackd2)-dev * libasound2-dev So, here is the project page: https://github.com/brummer10/Mamba and here you'll find the last release: https://github.com/brummer10/Mamba/releases/tag/v1.6 regards hermann

spectmorph-0.5.1

by Stefan Westerfeld

spectmorph-0.5.2 has been released. The two new main features (synchronizing morphing with the song tempo and positional play) are explained here: https://youtu.be/6E4HClXdV_Y If you haven't watched our video tutorial for the instrument editor added in 0.5.0, you can do so here: https://youtu.be/JlugWYPDp84 Overview of Changes in spectmorph-0.5.2: ---------------------------------------- * Support bpm/beat synchronization for LFO - new presets using beat sync LFO: Mars / Saturn * Add WavSource custom position playback mode * New Instruments: Sven Ah / Ih / Oh (another male human voice) * Store data in XDG directories on Linux: - move ~/.spectmorph directory to $XDG_DATA_HOME/spectmorph - move ~/SpectMorph directory to $XDG_DOCUMENTS_DIR/SpectMorph - create $XDG_DOCUMENTS_DIR/SpectMorph directory when needed (on write) - backward compatibility: use ~/SpectMorph if it already exists * Bump number of control inputs from 2 to 4 * Implemented midi CC control for smjack (General Purpose Controller 1..4) * Fix crashes caused by dangling MorphOperator pointers * Fix loading floating point wav files * Minor fixes and cleanups What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS users. Here is a quick overview of how you can make music using SpectMorph. - VST Plugin, especially for proprietary solutions that don't support LV2. (Available on Linux and 64-bit Windows/macOS) - LV2 Plugin, for any sequencer that supports it. - JACK Client. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, http://space.twc.de/~stefan
