[ANN] Qtractor 0.9.1 - A Pre-LAC2018 Release Frenzy Finale!

by Rui Nuno Capela

Hello again, The Pre-LAC2018 [8] release frenzy is now complete... Qtractor 0.9.1 (pre-lac2018 beta) is out! Change-log: - Displaying MIDI note(on) events as diamonds instead of simple rectangles (aka. Drum Mode) is now being introduced as an optional MIDI track property (Drums) and as a MIDI clip editor (piano-roll) visual option (cf. View/Drum Mode). - Extended multi-selection is now supported on all the Connections client/port lists, allowing for multiple (dis)connections at once. - Added LV2 UI sample-rate option support. - Always reset all internal dedicated MIDI controllers, eg. MIDI track volume (CC#7) and panning (CC#10), on Transport/Panic and after rendering export to aud1io (ie. Track/Export Tracks/Audio...) as needed to reset MIDI instrument plugins to nominal session state. - Fix, detect and preserve MIDI Bank-select method across MIDI track/clips editing operations. - Fixed MIDI track and clip note min/max display range while recording and also when duplicating tracks. - Added "All files (*.*)" filter to every file requestor dialog, wherever missing. - The tiny zoom-magnifier icons have been revamped. 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.

Current state of GPL Juce?

by Jean Pierre Cimalando

Hello. Recently, I have taken the task of updating and maintaining the old audio plugin HybridReverb2 which is programmed with the Juce framework. A LinuxMAO community member has pointed to me some info about recent Juce, more specifically about its change of license. Is Juce still compatible with libre software development like it used to be? There is rumor about Juce becoming proprietary, which emanates from some developers in a Carla thread. https://linuxmusicians.com/viewtopic.php?t=17814#p87547 I don't see an element to truly substantiate this claim. Does anyone know better about the whole Juce situation? Thanks. -JPC

broken make install in zita-ajbridge

by Nikita Zlobin

To kokkinizita When runing make install, resulting structure has /usr/bin as executable and /usr/share/man/man1 as probably, some archive. # ls -lR .: итого 4 drwxr-xr-x 3 root root 4096 май 17 22:34 usr ./usr: итого 36 -rwxr-xr-x 1 root root 31480 май 17 22:34 bin drwxr-xr-x 4 root root 4096 май 17 22:34 share ./usr/share: итого 8 drwxr-xr-x 3 root root 4096 май 17 22:34 doc drwxr-xr-x 2 root root 4096 май 17 22:34 man ./usr/share/doc: итого 4 drwxr-xr-x 2 root root 4096 май 17 22:34 zita-ajbridge-0.7.0 ./usr/share/doc/zita-ajbridge-0.7.0: итого 8 -rw-r--r-- 1 root root 39 май 17 22:34 AUTHORS -rw-r--r-- 1 root root 2185 май 17 22:34 README.bz2 ./usr/share/man: итого 4 -rw-r--r-- 1 root root 57 май 17 22:34 man1 Looks like, option -D causes to create almost complete path, without last element (man1 and bin), so those are treated as new file names.

Do professionals use Pulse Audio? ; xfce4-mixer

I also use dedicated machines for my DAW systems, with no PA installed. All audio is working with jack. My DAWs seldom connect to the internet so I don't have a heavyweight web browser (or many other desktop-type programs for that matter) installed. I actually dislike modern desktop Linux so much I switched my 'office' system to OpenBSD some time ago. That uses sndio (much simpler than PA) for browser audio. John

The Bay of Atlantis

by Louigi Verona

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
