[ANN] Qtractor 0.8.4 - End of Summer'17 release!

by Rui Nuno Capela

Yes, it's been like clockwork... Every two months or so, you stumbled with a brand new dot release, code-named after some of the same adjective-plus-noun (or vice versa) code-names. You knew the thrill and yet it lands no more. First, the code-naming joke has been just a parody--or was it the other way around?--to some well known Linux-distro 'alimalistic' code-name series. Then on it got rogue into some directed puns--remember the date when BitWig Studio 1.0 was first released? Yeah, the "Byte Bald" was there for the pun, on the very same day :) Well, that's all gone by now. Northern hemisphere seasons are the new norm and that's about two main reasons: first, it's where I live; second, due to an undeniable global warming effect pervading the globe, all geographical temperate zones are simply on the edge of extinction. More or less in a couple of decades or so. For the sake of brevity, I will just leave it like paying homage to those natural concepts that are facing an inexorable fate. And yet, there're still the good news: Qtractor 0.8.4 (end of summer'17) released! Change-log: - Assigned MIDI Controllers to plug-in's Activate switch are now finally saved and (re)loaded properly across sessions. - Audio clip panning option property is now being introduced. - Out-of-process (aka. dummy) VST plug-in inventory scanning now restarts automatically and resumes processing in case of a premature exit/crash; VST plug-in inventory scan/cache persistency is now in place. - Desktop entry specification file is now finally independent from build/configure template chains. - Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData). - Changing the View/Options.../Display/Custom/Style theme takes effect immediately unless it's back to "(default)". - Slightly slower but better approximation to IEEE 32bit floating point cubic root ie. cbrtf(). 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.

Fedora 25 x86_64; Pulseaudio removed; ALSA recording and playing from multiple sources - JACK?

by Philip Rhoades

People, For playing from multiple sources, ALSA plus the version of .asoundrc below has been rock-solid for a couple of years now: I now want to use things like "recordmydesktop" which work fine with the mic but they do not record sound from audio or video clips that are playing eg from YouTube or local mpv etc. So, yet again, I started to try and make sense of JACK because I was pretty sure that it could solve this problem - but I have found sound on linux has always been a major pain and messing around with configs and rebooting etc on my big workstation is tedious so I think I will try to get something working on my laptop to begin with. Hopefully some jack gurus will have some suggestions about how to do what I want to do? I presume it is possible? Thanks, Phil. pcm.!default { type plug slave.pcm "asymed" } # This is the audio output: pcm.dmixer { type dmix ipc_key 1024 slave { pcm "hw:1,0" period_time 0 period_size 1024 buffer_size 4096 rate 44100 } bindings { 0 0 1 1 } } ctl.dmixer { type hw card 0 } # This is the microphone pcm.dsnooped { ipc_key 1027 type dsnoop slave.pcm "hw:1,0" } # This makes both channels work together. pcm.asymed { type asym playback.pcm "dmixer" capture.pcm "dsnooped" } -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

Could not open ALSA sequencer as a client. ALSA MIDI patchbay will be not available.

by benravin

Hi, I'm using JACK version jackdmp 1.9.11-RC1, whenever I start the JACK server i get the subject line error message. I execute the following command. $sudo modprobe snd-seq-midi Is there a way to set this permanently and no need to execute every time i start JACK ? -ben -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-dev-f58952.html

Jack buffer requirements

by benravin

I want to know the optimal buffering which i can use for designing my application. My use case is as follows, I receive digital radio signals through a tuner and does the channel and audio decoding in separate threads. Finally the audio is send to jack callback and played out. How much of buffering is enough for real time streaming between threads. I want keep the optimal buffering between these threads. Please suggest guidelines for using with Jack. -ben -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-dev-f58952.html

Drift compensation document

by Benny Alexandar

Hi All, This is my first post to Linux Audio. I had a look at alsa_in/out programs, and the man page says it performs drift compensation for drift between the two clocks. I would like to know more about the implementation details such as the drift compensation using PI controller. Any paper/presentation documents available other than the C code. Please share me the details. -ben
