There are several methods being used in various kernels that are not purely
RT, but users are happy with the results. And the stock brown-bag kernel gets
better with each new version. So it's not like there is a really
slow doggy one to get stuck with out there anymore

Ahh i see. Thanks. Still my idea got halted since only recently could install the nVidia drivers lol

Im doing a "major" re structuring of my desktop (making a few partitions, reinstalling Windows 7, lots of stuff to move around), so probably im going to spend a lot of time reinstalling stuff and configuring it, at least, in the netbook, could compile Gparted, installed nvidias drivers, and installed latest gnome-disk-utility, now i need to know how to get the EFI working again...

jackd is the linux audio soundserver, the 'asio' of linux, but with perks

It's the blog of Lampros Liontos . I could only dream of creating such
a resource

I gladly pass along good info when I can. His page has
tons of it

Cheers

It's probably closer to the truth to say that Jack is similar to a cross of ASIO and ReWire: low-latency audio connection between programs and audio devices that you can manipulate into virtual signal chains similar to how analog filters are used.

And thanks for the plug; I always enjoy seeing new visitors. It feeds my ego.

Welcome to kvr! There are quite a few linux users here, a few linux developers
have forums, and a great number talented and generous folk, sharing
wit and wisdom. And some of the other stuff, when skirmishes erupt

Cheers

Thanks. I'll definitely do my best to give useful information. Additionally, I just finished another article on the use of the Rosegarden Sequencer/DAW/Notation Editor.

One thing I will say is that while it makes an excellent sequencer and notation editor, I might recommend sending the output to Ardour for the audio mixing and processing; Ardour is much more flexible where audio clips are concerned than Rosegarden.

But better.

JACK also provides a master transport control for any & all JACK-savvy clients. Makes it easy to sync a variety of apps.

There's now also the JACK Session protocol, but I haven't kept up on its use. Anyone here know how it's employed ?

Btw, add my vote for your blog, it's a good read.

Best,

dp

Okay, ASIO, ReWire, and MTC with superpowers.

As for the Jack Session Protocol, I don't think there's one unified form. I know there's Lash (doesn't support apps like Ardour or Rosegarden, so I can't see it as very useful) and Ladish (much better, although Gentoo's "Pro Audio" overlay seems to have conflict issues between this and Lash)

Then, there's the session manager built into the QT Jack Control application, which I cover as part of the "Using Jack" article, under "The Session Window."

Additionally, Ardour seems to have its own session manager as part of its project manager; when you start a project, all connections are resumed.

Finally, my preferred way is to create scripts with the command-line Jack commands to launch all wanted apps and then create the desired connections in one go.

And thanks for the vote! Every little bit makes my ego squeal with glee.

not directly on DAW topic, but linux related.

Anyone know much about JUCE or the JUCED fork? I saw a link to a google code page with a selection of plugins that had been ported using JUCED (the person involved seems to be the Jucetice person) quite a while ago. A few were plugins and others were stand-alone applications. Anyone know if its possible to compile things like the drum machine there as a plugin and if so, how? Any thoughts on that would be good, if anyone has had much joy with them

Cool stuff there.

None of its desperately clear to me. I'm going to run through some of the 'walk throughs' to see if I end up with plugins rather than stand alone apps.. Cheers./

Another general Linux question. I'm on Ubuntu at the moment but was thinking of freeing up some space by losing an old Windows install and was wondering about opinions on different distro's.

Was kind of tempted by Fedora because of the Planet CCRMA bit and people saying theres consistent development for the audio side of things. Any others to look into?

I use Arch Linux for all my Linux needs these days. It's not a distro for beginners but if you're not afraid of a command line and can read simple instructions then it's trivial to set up a base system. Once set up you never have to reinstall it and it will only be as bloated as you allow it. (My current install is 3+ years old and only has one browser, one text editor, one image viewer, etc. etc.) It's kind of the Reaper of Linux distros. It's a rolling distro so all of your packages will always be the latest release versions. The ArchWiki is probably one of the richest resources on Linux anywhere. The forums sometimes seem unfriendly because they commonly say "this is covered in the wiki" but it is true 99.99% of the time.

Anyway, enough with the advocacy. There is a pool of pro audio users among Arch Linux users so there are many programs to choose from. If there isn't a program in the main repositories then chances are it is available in the AUR or user repository. For example, Ardour 3 SVN is in the AUR so it's available to all Arch Linux users with a simple command.

There is also a version called ArchBang that includes a LiveCD and a ready-to-install minimal environment based on the Openbox window manager. Once installed it's like any other Arch install but you already have a working GUI and can go from there - KDE/LXDE/Gnome/XFCE/etc. I installed ArchBang on an ancient laptop (600 MHz Pentium III, 392 MB RAM) and it's blazing fast (for 600 MHz). It even boots up faster to a working desktop than my 3.0 GHz quad-core Q9550 running Windows 7. Definitely extended the life of this 1999 laptop.

There's also an audio-based LiveCD: http://obsoleteaudio.org/software/synthbox
