KXStudio 12.04.1 released!

Written for KXStudio by falkTX on 2013-01-05

After much hard work, a new release of KXStudio is ready!
The previous ISO images were getting old, and since Cadence (and KXStudio in general) is now much more stable, it was time for an update.
Existing KXStudio users already have 90% of the changes and fixes as KXStudio uses the repositories for everything.
Still, this is a big milestone for the project. It's a step towards perfection.

Here's a quick list of changes since the previous 12.04 release.

- Add AriaMaestosa, Giada and Petri-Foo to the DVD and default install
- Upgrade Cadence to the beta1 release (lots of fixes!)
- Fully up-to-date apps and plugins (as of 30/12/2012)
- Use KDE 4.9.4 on the Live-DVD (repositories now have 4.9.5)
- Use Firefox-KDE PPA on the Live-DVD

- Add kxstudio-text plymouth (used when no gpu drivers are available)
- Fix plymouth Live-DVD "eject disk now" text not visible (and any other labels/info)
- Change KDE desktop theme to slim-glow (backported latest release from KDE 4.10)
- Change cursor theme to oxy-zion
- Disable KDE bouncing cursor by default
- Use Claudia-Launcher instead of Klaudia in KDE kickoff (start menu)

- Auto-disable PulseAudio respawn
- Set default asoundrc file to snd-aloop
- Set default jack prio to 85
- Use ALSA-Audio bridge instead of PulseAudio (no longer installed by default)

Welcome Wizard:
- Add theme screenshot button
- Add theme font size option
- Auto-register 64bit WineAsio too (done in 'wine stuff' step)
- Don't update user theme to KXStudio by default
- Disable theme updates if not running KDE4 or XFCE

The DVD works properly now (no need to re-login to apply settings anymore) and also has an option to boot to RAM (requires at least 3Gb to work).
You can download the new ISOs at the KXStudio website,

This release is dedicated to Hatsuke Miku, a [virtual] Vocaloid singer that recently has seen original artwork released under a Creative Commons license.
We believe that actions like this one (and others in 2012) indicate that the world embraces open-source culture more and more, every day.
You can find more about Miku here (, and the its CC artwork here (

We hope you enjoy KXStudio and the updated Cadence.
Soon enough the website will have full documentation for it and other subjects, so stay tuned!

Call for Testing - Cadence pre-Beta

Written for KXStudio by falkTX on 2012-09-17

Hello everybody!
We're almost in the Beta1 release of Cadence!

For those of you who don't know, Cadence is what KXStudio uses to manage the entire audio ecosystem.
'Cadence' is by itself the main app of a series of tools (call it the "Cadence tools").
There's 'Catia', a simple JACK patchbay; 'Claudia' is a ladish frontend, very similar to Catia (and gladish); 'Carla' is the plugin host.
Then there's the small tools - JackMeter, JackSettings, Logs, Render and XY-Controller (their names give away their funtionality).

Cadence and its tools are currently being documented, and pages will appear here: (incomplete)
(There's a topic in the KXStudio forums discussing the documentation here:

If you're running KXStudio now, you either have updates or have recently updated Cadence and sub-packages.
I'll be pushing the latest Cadence code to the KXStudio repositories frequently in the next days while the testing happens.
ArchLinux users can use this AUR package:
You can checkout what's going on in the Cadence commits page:

Not everything is fully ready right now, here's a list of things that will still be done before the Beta1 release:
- Cadence audio-bridges, currently disabled
- Carla Windows plugin-bridge support (Linux 32/64bit bridges are already in place though). Note that this will remain an experimental feature even for this release.
- Carla-Control is unfinished, the GUI will do nothing useful right now.
- Catia ALSA-MIDI support is currently disabled, but will still not be activated for this release.

So, what needs testing?
Pretty much everything. :D
Run the apps, click on random stuff and try to make them crash. When that happens, or if notice something weird, please report the bug.
I've done my best to make the tools as stable + crash-free as possible, but we can never be too sure about these things.

You can report bugs directly in the official bug page at
(Reporting a bug in that page allows you to receive notifications whenever something is done related to it).

Thanks in advance to everyone that decides to help!

KXStudio 12.04 is out!

Written for KXStudio by falkTX on 2012-05-25

Hey there everyone, it's that time again!
KXStudio is now ready for the masses, now using Ubuntu 12.04 as the base.

KDE4 remains the officially supported Desktop, with XFCE on 2nd place.
For this release I re-introduced the ISOs, although only 32bit for now. So now installing KXStudio can take 3 forms: Live-DVD, Ubuntu upgrade or NetBoot.
The Live-DVD uses KDE4, if you want XFCE instead please install UbuntuStudio first then follow the upgrade instructions as detailed here.

The Cadence tools are currently being ported to python3 in a new repo -
Catarina, Catia, Claudia and the minor tools are almost beta state right now. Carla and Claudia-Launcher are still in the works (but already very functional), and the real 'Cadence' app is yet to be ported.
These tools are already available on KXStudio in their latest git state, and will be released as beta for the while world very soon.

The DISTRHO plugin suite is now near completion and it's targeted for a new release this weekend.
The entire collection is already available in the KXStudio repos but yet part of the meta-packages (will be added shortly after the official release).
Generic linux binaries will be made available for non-KXStudio users as before.

Cadence Alpha 1 released

Written for KXStudio by falkTX on 2011-12-06

Hello there everyone,
Cadence Alpha 1 is finally here!
Some Ubuntu users already know about it, but now it's officially released to the public in a somewhat stable version (but still alpha nonetheless).

So what is Cadence?
Basically it's a set of applications and small tools useful for audio tasks. It's being developed by falkTX, using Python and Qt4 (and some C++ where needed).
Cadence itself is the main application. It performs system checks, manages JACK, and makes system tweaks.
Cadence also provides an interface to several other tools/applications useful for audio work.
These are:

---> Catarina
A Patchbay test app.
Created while the patchcanvas module was being developed, it allows the user to experiment with the patchbay, without using JACK or LADISH.
You can save & load patchbay configurations too. Not sure how much useful this app is now though...

---> Catia
JACK Patchbay, with some neat features like A2J bridge support and JACK Transport.
It's supposed to be as simple as possible (there's Claudia for advanced things), so it can work nicely on Windows and Mac too.

---> Claudia
LADISH frontend; just like Catia, but focused at session management through LADISH.
It has a bit more features than the official LADISH GUI, with a pretty preview of the main canvas in the bottom-left.
It also implements the 'Klaudia' add-application style when using 'Klaudia' database mode.

---> Carla Multi-plugin host for JACK.
It has some nice features like automation of parameters via MIDI CCs (and send control outputs back to MIDI too) and full OSC control.
Currently supports LADSPA (including LRDF), DSSI, LV2 and (native) VST.
This application is still under heavy development and may change/break at anytime.

---> Carla Control
An OSC Control GUI for Carla.
You get the OSC address from the Carla's about dialog, and connect to it.
Supports controlling main UI components (Dry/Wet, Vol and Balance), and all plugins parameters.
Peak values and control outputs are displayed as well.
Custom Plugin GUIs are not supported for obvious reasons...

More details about Cadence and these tools are available in the KXStudio Applications page:

A quick introduction video is planned to be released soon, so it can give a better explanation about each one of the tools.

Downloads are available at:

Ubuntu users can use the KXStudio-Team PPAs and install the 'cadence' package. For ArchLinux, 'cadence-git' is available in AUR.

The Future of KXStudio

Written for KXStudio by falkTX on 2011-11-25

As you might have noticed, there has been no new stuff recently. KXStudio is developed by one person only, falkTX, and sometimes there's just too much work to do.
One of the things that takes most of the time is managing the repositories. For Ubuntu there is already support for 5 versions (Lucid, Maverick, Natty, Oneiric, and starting work for Precise), and also the ArchLinux one. This is simply too much work for one person right now.
So, after much consideration, the following decisions were made:
  - No more official support for versions before Oneiric, although important software will still be updated (Ardour and Qtractor for example)
  - The ArchLinux repository will be removed. Users can still use AUR, and expect KXStudio related packages to be kept up-to-date
  - Starting next year, serious work will begin to support the upcoming Ubuntu 12.04 release, trying to get integration with UbuntuStudio as much as possible. Once this starts, Oneric will only get important PPA updates, like we're now doing for pre-Oneiric versions.

But there is also good news - Cadence is very near it's first alpha release, and DISTRHO LV2 plugin ports are coming soon (it was awaiting the latest set of LV2 updates).
Stay tuned for updates!
