Announcing a new release of project "droning", tune 281 "The Bay of Atlantis". *Stream it here:* https://louigi.bandcamp.com/album/281-the-bay-of-atlantis *Word from the author:* Extensive work went into this creation. I wanted the tune to create a feeling that this is one solid composition, not a soundtrack with distinct segments, but something rather like an ocean which is in one instance is calm and in the other - furious. But still just one single ocean. To all of you travelers out there, and to those of us who find visiting nonexistent places important. *Technical specs:* Qtractor, Rakarrack, Carla, Kluppe, seq24 and a number of LV2 plugins. Zyn is used, although a number of sounds came from other sources. -- Louigi Verona https://www.patreon.com/droning https://louigiverona.com/

Do professionals use Pulse Audio? ; xfce4-mixer

by Philip Rhoades

People, I am not a professional LA user but I have regard for what serious LA users have to say. A post turned up on the Fedora XFCE list about removing xfce4-mixer for F29 - I responded with: "Every time I upgrade I immediately UNinstall PA and use ALSA only - so I still depend on xfce4-mixer . ." Someone replied that PA has greatly improved since the early days especially and "controlling streams separately is an added feature" - but I can do that with the .asoundrc I have now - are there any good reasons for me to reconsider the situation the next time I do a fresh install? (I realise I am likely to get biased comments here but I am not going to post on a PA list . .). Thanks, Phil. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

spectmorph-0.4.0

by Stefan Westerfeld

spectmorph-0.4.0 has been released. Overview of Changes in spectmorph-0.4.0: ---------------------------------------- * Windows is now supported: provide 64-bit Windows VST plugin * Plugin UI redesign - use pugl library for portability (uses GL + cairo) instead of Qt5 - use categories for instruments - directly support instrument names in linear morphing - get rid of Qt5 dependency for libspectmorph, smjack, VST and LV2 plugins - UI now has "Zoom" feature to support higher DPI displays * Use non-linear configurable new velocity -> volume mapping for midi * New instrument: French Horn * Improved tools for building custom instruments - tools are now installed by default - sminstbuilder files support new syntax for relative paths - encoder cache moved to ~/.cache/smenccache, which is created if necessary - use number of processors as default for jobs * LPC/LSF support removed * Some portability fixes for macOS (which however isn't supported yet) 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 and Windows 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) - LV2 Plugin, for any sequencer that supports it. - JACK Client. - BEAST Module, integrating into BEASTs modular environment. Note that at this point, we may still change the way sound synthesis works, so newer versions of SpectMorph may sound (slightly) different than the current version. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads/spectmorph-0.4.0.tar.bz2 There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

[ANN] Qtractor 0.9.0 - An Early Spring'18 Release!

by Rui Nuno Capela

Hello? Qtractor 0.9.0 (early spring'18 beta) is now released! The change-log for this spring-time release goes as follows: - New View/Options.../Plugins/Experimental/Show plugins on track list/left pane option is in effect on tracks that are tall enough in height for their plugins list to fit on the Bus column. - Fixed a day-zero bug over the MIDI Insert (Send/Return) pseudo-plugin, which was duplicating MIDI events onto the next LV2 plugin in chain, causing strange hanging notes, mutes, retriggerings and what not. - MIDI track and clip note min/max range display now fixed. - MIDI Program Change events (PC) now have their proper program number as parameter, instead of value, on the internal MIDI event representatio n. - Merging MIDI clips while on SMF Format 0 has been fixed: was merging always onto the same MIDI channel (2), most often the wrong one, resulting in an empty or blank clip. - When importing from standard MIDI files (SMF), set track names from Mtrk TRACKNAME meta-events instead of filename. - Avoid asking to save as to existing or just newly created clip file-names, whenever possible. - Disable singleton/unique application instance setup logic when the display server platform is not X11. - Whether to use native file browser/requester dialogs is now an effective option when launching under NSM session management (was once disabled initially). - Content files are now saved as symlinks when saving to JACK and/or NSM session directories/folders. - Trying to get CC14 MSB+LSB (course+fine) running status on, no matter whether each pairing event are under 200ms apart. - Possible VST plug-in GUI reparenting hack/fix on Qt5/Xcb. 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] hexter DSSI softsynth 1.1.0 release

by Sean Bolton

I'm pleased to announce the 1.1.0 release of hexter, a DSSI softsynth plugin that models the sound generation of a Yamaha DX7 synthesizer. This release provides support for DSSI hosts which don't support run_multiple_synths(), for example, Carla and Renoise. Each instance of the plugin is run separately, and support for the global polyphony limit has been removed. Several bugs and numerous compiler warnings have been fixed. Find hexter here: http://smbolton.com/hexter.html The distribution tarball is here: https://github.com/smbolton/hexter/releases/tag/version_1.1.0 More information on the DSSI plugin standard, available hosts and plugins can be found here: http://dssi.sourceforge.net/ hexter is written and copyright (c) 2018 by Sean Bolton, and licensed under the GNU General Public License, version 2 or later. Thanks to Andreas Müller for contributing a bug fix. Have fun! -Sean

rosegarden doesn't use system qt5 font

by Nikita Zlobin

It seems, that rosegarden forces gui font to be Sans. On my system default sans seems to be droid. In qt5, with russian locale, russian bold letters are drawen by some kind of Courier New. Regular font is still Sans, and this bug seems to affect all qt5 stuff - i noticed it first time in Converseen. After i changed to Deja Vu, and yet later began to search for more interesting fonts (up to tomorrow i had Exo), problem disappeared. For qt5 config i use qt5ct. Today i assidentally discovered font pair, which imho looks awesome with programs like MuseScore and Rosegarden. I don't know, is it intended to force some specific font... so i want to propose as variant to use any Serif font. Last time i tried CMU fonts: http://cm-unicode.sourceforge.net/ CMU has very interesting (imho) serif variants (though simple sans style also presents). Especially i want to note: - Contrete - as easy to read as any Serif, but more interesting, than its own CMU Serif - i.e., it looks much sharper. - Pair of two fonts: - - CMU Serif Upright Italic: regular ornamental font - - CMU Classical Serif: former's italic kind (both have bold kinds) And i would note, there is some mess in names. Thus, upright italic is not really italic (just looks ornamental), while simple classical looks like "CMU Serif Upright Italic" Italic :). Would be better for them, of course to be in one "CMU Classical" font, providing as usually - 4 kinds. This of course, is for aesthetes :) Screenshot with musescore, with CMU Classical font: https://musescore.org/sites/musescore.org/files/2018-03/musescore_2018-03-1… I guess (it is still my imho+taste), all these Serif/Concrete/Classical fonts would look much better in rosegarden. Can't tell about other (even musical) software, but for now i made "CMU Serif Upright Italic" default font - in qt5ct, desktop appearance settings (xfce), and now trying to get for qt4. It exactly works with qjackctl and musescore. ________________________________ About qtractor, if Rui Nuno Capella reads, there are few places, where, where sans is forced: - clock on toolbar, - files list and track list use sans italic. I don't know, is it sideback of setting to italic, but track list ruler uses regular sans. But still, BPM display, near of clock, followes system font.

[ANN] Vee One Suite 0.9.0 - The End of Winter'18 release

by Rui Nuno Capela

Ahoy there! 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 once again released just before the season ends. As before, all available in dual standard forms:<ul> - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The changes for this end-of-season goes as follows: - Introducing Scala micro-tuning classes, borrowed, stirred and refactored from original Nick Dowell's amsynth code, all under the GPL umbrella, of course. - An internal note-key/frequency indirection table is now in place, as a baseline for any micro-tuning implementations. - Whether to use native file browser/requester dialogs is now an effective option when launching under NSM session management (was once disabled initially). - Initializing and/or requesting a New blank preset doesn't open a sample file picker dialog anymore as it was more than nagging while under on NSM sessions. (applies to samplv1 [2] only). - Trying to get CC14 MSB+LSB (course+fine) running status on, no matter whether each pairing event are under 200ms apart. - A little hardening on the configure (autoconf) macro side. In order of (historical) appearance: **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.0 (end-of-winter'18) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
