[LAU] [ANN] Qtractor 0.6.4 - The Baryon Throne beta release!

Aw, snap!

   Wait, there's no big deal (nor chromium's) cosmic (mis)alignment 
being announced here now. Rest calm. Sorry to delude some of you :)

   But, there's one (notable) leap on this tiny side and part of the 
universe... (or is it a multiverse? move along...) What I really want to 
tell is all about this happening and none else's freaking business:

   Qtractor 0.6.4 (baryon throne beta) is released!

Release highlights:
* Punch-in/out over loop-recording/take modes (NEW)
* Latch/momentary MIDI Controllers toggle mode (NEW)
* JACK client/port pretty-name (metadata) support (NEW)
* Custom style and color themes (NEW)
* Mixer strip multi-row layout (NEW)
* Muted audio tracks monitoring on playback (FIX)
* Clip fade-in/out resize on time-stretch (FIX)

As for the clueless (as if there's any):

   Qtractor is an audio/MIDI multi-track sequencer application written 
in C++ with the Qt4 framework. Target platform is Linux, where the Jack 
Audio Connection Kit (JACK) for audio and the Advanced Linux Sound 
Architecture (ALSA) for MIDI are the main infrastructures to evolve as a 
fairly-featured Linux desktop audio workstation GUI, specially dedicated 
to the personal home-studio.

   Well, although this being yet another milestone--if one may call it

[LAU] Ideas - live gig streaming

Hey list!

So a local haunt I work at frequently doing any number of things, including sound, playing or sitting in for
someone, maintenance, repairs, installs, etc. great little place in Placerville, CA.

I'm looking for input for these items directly (please go offline or start another thread if you want to talk
about unrelated stuff);

Audio / video live streaming 
- post mix audio to web interface with synced video.

-coverage of all in minimum of apps but some control over general mix (pgm) (master comp/EQ only if needed)
and video basic adjust (contrast, luminance, phase, etc.

- network side bandwidth / bs quality ...min bandwidth / network management issues - MTU, adjust for max
glitch less thruput. 

Hoping to reach maybe 200 ppl via interwebs... Interactive chat - video return with possible audio availability.

As an aside, I'm starting a sound school at the premises in the new year. Guess what I'm gonna promote in the
recording / PC sound management segment?! The ears prick up immediately in the circles I run in when I speak
of totally NON reliance on proprietary ( spell - expensive ) OS and awesome audio apps!! 

All ideas toward 

Active examples would be awesome. Pls peeple... I don't want to be a jerk about 

(on topic stuff - I'm prolly the last one who should speak ... Some of the stuff that comes up is just
distracting for me personally. I come here for audio upon Linux info. Not lectures on how to behave or what
my opinion should be! Hopefully, with as much tact intended as possible here, I speak not just for myself?)

[LAU] soundfont question

This is the first time posting to the mailing list, I appreciate any help that is given. I have a 2 soundcard configuration: An SB live and Gina from Echo audio. The Gina only provides audio, which is the main card I wish to use for routing my audio signals. The other card is an SB live intended for using the midi interface (MPU 401 or something to that effect), and to load a soundfont into the cards internal synthesizer. My question is, how do I use the SB live's soundfont synthesizer capabilities and route it to the Gina for audio playback. I'm using Jack and do not know how to do this. I'm wondering if it is even possible. I do not want to use the SB live's audio output jack just to hear the soundfont I loaded. I would like the Gina to handle all audio connections. Thank you again and I appreciate any help with this issue. Let me know if more information is needed.

[LAU] caustic with wineasio


I'm having a blast with caustic (music environment for android, ios,
windows + more). It works fine through wine, but for better realtime
performance, I'd like to get it working with wineasio.

I have wineasio working with reaper, so I copied the from that
folder to .wine (freshly made, only used with caustic):

atte <at> skagen:~/.wine$ find | grep asio

I then registered it with:
atte <at> skagen:~/.wine$ regsvr32 .winelib/
Successfully registered DLL .winelib/

I have this in my ~/caustic/config:

atte <at> skagen:~$ cat ~/caustic/config

Still, caustic refuses to play, and right upon launch I get this in the
terminal that started caustic:

fixme:avrt:AvSetMmThreadCharacteristicsW (L"Audio",0xb7e9d8): stub
err:ole:COMPOBJ_DllList_Add couldn't load in-process dll L"wineasio.dll"
err:ole:CoGetClassObject no class object
{48d0c522-bfcc-45cc-8b84-17f25f33e6e8} could be created for context 0x1
err:ole:COMPOBJ_DllList_Add couldn't load in-process dll L"wineasio.dll"
err:ole:CoGetClassObject no class object
{48d0c522-bfcc-45cc-8b84-17f25f33e6e8} could be created for context 0x1

Any ideas how to get wineasio going?

NB: Although in a different .wine-folder, wineasio is runing really well
on my box(es), so I know it's possible with my combination of jack
version and wine version.

NB: Debian wheezy, if it matters...

[LAU] Xruns :(

Recently I updated my 'office' computer, which I often use for experimenting
(I don't try anything new on the DAW) and suddenly I'm getting a *lot* of Xruns
and, apparently, very high CPU loading.

Eventually I found the cause. Going from linux kernel 3.2 to 3.16 :(
This, apparently, does very aggressive CPU frequency scaling. Drop back to 3.2
and all is sweetness and light again.

The question is whether there is a reasonably straightforward way to stop this
behaviour. Doing the usual searches doesn't seem to turn up anything useful.

Any help gratefully appreciated.

I would add that I've double checked that the bios is set for 'performance'.

[LAU] jack and the merging of soundcards

I may perspectively run into a shortage of audio inputs and stumbled 
across a blog, that reads like it is possbile to "merge" two soundcards 
into one virtual, that eventually looks as a single one to alsa. 
However, that blog does not mention jack.

Also, in an stone old ardour thread Paul Davis suggests to a similar 
problem: ", then you simply get 2 digifaces", but again, this may have 
been before the rise of jack.

And now I am wondering wether this is a possible or even reliable way to 
trick jack into being able to to finally handle more than one soundcard, 
if presented by alsa as being a single one.

I am honest, that asoundrc is way beyond me, as alsa alway has been, 
thats why I am asking and I am thinking about using two ordinary, 1st 
generation, pre HDSP, Hammerfall cards to expand ADAT IO. Would be 
cheaper than investing into a raydat, when time has finally come.

The posts for reference:

Any thoughts on this? Or won't it work with jack?
