[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.

FFADO 2.4.1 released

by Jonathan Woithe

FFADO version 2.4.1 is now available, a package of userspace drivers for firewire audio interfaces. This is a bugfix release with many of the changes associated with the use of python3 and distribution packaging. This is a source-only release which can be downloaded from the ffado.org website at http://ffado.org or via the direct link: http://ffado.org/files/libffado-2.4.1.tgz Issues addressed in this release include: * Fix some python syntax which was not compatible with python3. These were missed during the preparation of FFADO 2.4.0. * Modify the SCons build system to allow for scons running under python3. As of this release there seem to be a number of issues in scons itself when running under python3, so building FFADO in this environment is not yet guaranteed. * Merge distribution patches provided by package maintainers. * Address some difficulties experienced by package maintainers when compiling FFADO. * Improve the output of ffado-diag. Thanks to the developers and users who contributed to this release: Nicolas Bouleng, Benoit Delcour, David Kastrup, Hector Martin, Orcan Ogetbil, Dave Plater, David Runge, Jano Svitok and Jonathan Woithe. If an omission has been made please contact us through the ffado-devel mailing list so this can be corrected.

linuxaudio.org is back online!

by Jeremy Jongepier

Dear all, We just enabled all mail services for linuxaudio.org again. All mailing lists are working again and mail can be sent and received for the linuxaudio.org domain. A short recap of what happened is that linuxaudio.org got compromised on January 29th, probably with a compromised private SSH key or password from an account with shell access. The attacker checked the kernel, saw that it was vulnerable to Dirty COW¹, pulled in an exploit and got root. This was quickly discovered by the IT department of Virginia Tech University that disconnected the server from the internet and started a forensic investigation procedure. As part of their IT security policy the server had to be reinstalled and everything had to be set up from scratch again. In the meanwhile I built an alternative setup and after some discussion we agreed on moving linuxaudio.org away from the Virginia Tech server. So linuxaudio.org got a new home after 15 years at Virginia Tech². We're very, very thankful that we could host linuxaudio.org on their servers and we can't stress enough how grateful we are for all the work that has been done on the side of Virginia Tech after the hack. linuxaudio.org now lives at Fuga³, a fully open source OpenStack⁴ cloud based in The Netherlands. Fuga is part of Cyso⁵, the company I work for. The linuxaudio.org ecosystem now consists of three separate servers, a web server, a mail server and a storage server. We rebuilt everything with portability and scalability in mind with a strong focus on security. You can never prevent passwords or SSH keys getting into the hands of hackers but we'll try to keep the servers as up to date as we can to narrow down the attack surface as much as possible. A big thank you to all those who helped out! It was quite a ride but it seems as if most part of the linuxaudio.org ecosystem is accessible again. If you find any web pages, downloads or other bits and parts that don't work properly then please let us know so we can take a look at it. Many thanks in advance and also many thanks for bearing with us! Best, Jeremy Jongepier root(a)linuxaudio.org ¹ https://dirtycow.ninja/ ² https://icat.vt.edu/ ³ https://fuga.cloud/ ⁴ https://www.openstack.org/ ⁴ https://cyso.com/en/

PipeWire, and "a more generic seeking and timing framework"

by Jonathan Brickman

Not really sure the subgraph is so good -- one of the things JACK gives us is the extremely solid knowledge of what it just did, is doing now, and will do next period. If I run Pulse with JACK, it's JACK controlling the hardware and Pulse feeding into it, not the other way around, because Pulse is not tightly synchronized, whereas JACK is. But if you can make it work as well, more power to you. Concerning seeking and timing, though, I have had to wonder. My impression of JACK for a long time (and more learned ladies and gentlemen, please correct) is that it uses a basically round-robin approach to its clients, with variation. I have had to wonder, especially given my need for this <https://github.com/ponderworthy/MultiJACK>, how practical a model might be possible, using preemptive multitasking or even Ethernet-style collision avoidance through entropic data, at current CPU speeds. It's chopped into frames, right? Couldn't audio and MIDI data be mapped into networking frames and then thrown around using the kernel networking stack? The timestamps are there...the connectivity is there...have to do interesting translations... :-) Could be done at the IP level or even lower I would think. The lower you go, the more power you get, because you're closer to the kernel at every step. -- *Jonathan E. Brickman jeb(a)ponderworthy.com <http://login.jsp/?at=02e47df3-a9af-4cd9-b951-1a06d255b48f&mailto=jeb@ponder…> (785)233-9977* *Hear us at http://ponderworthy.com <http://ponderworthy.com> -- CDs and MP3s now available! <http://ponderworthy.com/ad-astra/ad-astra.html>* *Music of compassion; fire, and life!!!*
