[ANN] Qtractor 0.9.4 - The Winter'19 Release

by Rui Nuno Capela

Dear all, Qtractor 0.9.4 (winter'19 beta) is released! Changes for this season are as follows: - Drag-moving and copy-pasting existing clips, while over the main track-view, now shows the respective (audio wave-shapes and MIDI piano-rolls) graphical representations, as much as possible. - For good and bad, session name changes now trickle down to respective audio/MIDI file names as well. - Audio output monitoring meters may now be shown on MIDI tracks and buses as a default user preference option (View/ Options.../Plugins/Instruments/Show audio output monitoring meters) and also in plugin list context sub-menu (Audio/Meters). - Custom color (palette) themes can be exported to and imported from external files. - LV2 plug-in UI GTK2 and X11 in Qt5 host native support are now enabled on configure by default. - Fixed minimum input value as 10% (was 1%) for audio clip time-stretching in the Clip / Edit... dialog. 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.

xjadeo compatible format from kdenlive

by Adrienne Teicher

Hello, I'm hoping that someone on this list is an xjadeo/kdenlive expert and can help me out. I also posted in the kdenlive forums. I have not been able to find a rendering format this is compatible with xjadeo. The error xjadeo gives is Index Error. File is not suitable. I read that this has something to do with "index frames". A workaround I have is to export the project in kdenlive, and then convert it in handbrake with their "Vimeo Youtube HQ 1080p60 preset". The reason why this works seems to be the following text in the "More Settings:" in Handbrake: keyint=30:min-keyint=15:ref=1:bframes=2:b-pyramid=none I tried to create a preset in kdenlive with the above settings in Parameters. It worked when I ran a test on a short (ca. 1 minute) video, but the same error above occurs when i export a longer (ca. 1 hour) video. Does anyone have an idea of a failsafe format for xjadeo from kdenlive? Thank you!

Output port for Jack audio over bluetooth

by Ace Path

Hey yall Anyone have any success with using jack to output audio so any jack compatible apps can play through a speaker? Successfully have used bluealsa to aplay audio and pulseaudio (which I wouldn't prefer to use) to connect with a Bluetooth device as an audio sink, a2dp. But I've failed to make output ports so that I could actually output anything over bluealsa (I want to use this for live audio use, not just playing premade files via aplay), and the pulseaudio bridge input ports don't actually play any signal over bluetooth, though pulseaudio based apps like firefox do work, I can't force any other audio through. Suggestions, insights, examples welcome, and thanks in advance for any feedback Best regard's to all and hope to see yall at LAC, I'll be going for my first time

Bristol audio failed with JACK

by Jeanette C.

Hey hey, I just started Bristol and encountered a few difficulties. In the end my peril might have been that Bristol/Brighton reported that the audio failed. Using the following command I also got a message complaining about not being able to connect the the graphic display: startBristol -cli -audio jack -midi alsa -b3 I also tried different emulations and using bristol directly. Adding the -gui option (apparently to disable/not start the GUI) and -verbose option. It always failed and never specified the audio problem. The ALSA driver was correctly started and the sequencer port showed up as expected, before Bristol timed out trying to setup the audio. Any ideas? I have a feeling that I needed to do something more, but it's been a while.

Aeolus segfaulting

by Jeanette C.

Hey hey, after a long time, I have started Aeolus again, with the following command: aeolus -J -S /usr/share/aeolus/stops After all registers are retuned Aeolus segfaults in the readline initialisation. Gdb tells me that the last message comes from libncursesw.so.6 (no specific function). Going "up" in gdb I get the following: #2 0x00007ffff74ae746 in _nc_read_entry2 () from /usr/lib/libncursesw.so.6 #3 0x00007ffff74a73ea in _nc_setup_tinfo () from /usr/lib/libncursesw.so.6 #4 0x00007ffff74a7772 in _nc_setupterm () from /usr/lib/libncursesw.so.6 #5 0x00007ffff74a7cb4 in tgetent_sp () from /usr/lib/libncursesw.so.6 #6 0x00007ffff75089bd in _rl_init_terminal_io () from /usr/lib/libreadline.so.8 #7 0x00007ffff74ed51d in rl_initialize () from /usr/lib/libreadline.so.8 #8 0x00007ffff74ed7ed in readline () from /usr/lib/libreadline.so.8 #9 0x00007ffff7fc819e in Reader::thr_main() () from /usr/lib/aeolus_txt.so ... I am running Aeolus 0.9.7 from the Arch Linux community repo. I have also tried installing this version manually, with the same result. Checking with Gdb the correct aeolus_txt.so file is loaded from the correct aeolus executable, i.e. /usr/local/bin/aeolus for the self-built version. I have not encountered any other issues with ncurses or readline based programs. Ncurses version: 6.1.6 Readline version: 8.0.0 One system specialty: the terminals are resized using stty, to get an effective size of 80x30. Can some one verify this issue with the text UI? Any suggested remedies perhaps?

Plugin recommendation: chorus for voice

by Jeanette C.

Hey hey, I know this holds many opening for personal taste, but... I am looking for a good chorus plugin (LADSPA or LV2) to put on voice for an electronic piece. Think lush pads, reverb and an ambient feel. I am looking for some stereo width and perceptible chorusing without being so aggressive as to disguise the itch of the vocals. I am usually working with the CAPS chorus and lately with the CS2 chorus. But somehow I don't like the CAPS one on monophonic instruments/vocals and the Csound chorus is missing the stereo element. Any suggestions are welcome.

Re: [LAU] systemd woes with jackd and its permissions (raspbian)

by David Runge

Everyone's entitled to their opinion I guess, but how on earth does this help with the question at hand? If you're plainly here to rant about how bad systemd is (or rave about how great your particular distro is), maybe find another mailing list to do so. It's getting quite annoying (given your recent track record on that particular topic) and really doesn't provide any useful information regarding the original topic, especially as you fail to supply information on why and how a jackd-as-a-daemon-setup on Devuan could be considered more suitable or would even look like. Please be constructive and provide examples instead of bad-mouthing other people's work. e.g. "Hey look, this is how we do things on Devuan - without systemd - to have jackd start as a daemon. You can also use that instead of Raspbian." Doesn't hurt, does it? Best, David -- https://sleepmap.de
