QTractor

Postby jdm7dv » Fri Mar 30, 2018 10:07 pm

I'm using QTractor and an the KX repositories with Ubuntu Studio.
And an AKAI MPK249 MIDI controller. Can someone tell me the correct way to route the inputs and outputs?
In a Ladish studio session.

Thanks,

Also How to add an app to the Claudia launcher.

If I were you I'd start with Qtractor and forget about Claudia and Ladish for a while. If I'm correct then Claudia and Ladish are only to connect Midi devices etc. One can do that w/ Qjackctl and/or Qtractor too (see screenie below), with which many people here have experience. I do not know if many people use Ladish/Claudia.

Good luck! :)

P.S. The Akai MPK249 is a Midi keyboard w/ some pads and knobs isn't it? You might want to tell us what you want to use it for: as a keyboard for a synth; to finger drum; etc.? :?:

Qtractor has a graphical dialog to do audio and MIDI connections.

To control elements within Qtractor use MIDI learn: right click the element and choose MIDI, then move the controller's fader or turn the knob.

@bluebell: I now that you are heavy user of Qtractor and wonder if/why you don't have any issues with crashes. What OS do you use? I'm on KXstudio 14.04. and especially some Calf Plugins (Analyzer, Filter, etc.) are regularly crashing. (btw. I also opened a thread in the sequencer forum).

Cheers,

There was a time when I had occasional crashes immediately after loading big projects or creating new buses, but that's a year ago,

The only occasional problems I have are:
- not all klangfalter instances load their impulse response
- jumping around (placing the song cursor) while Qtractor is playing brings audio clips out of sync

I use Xubuntu 14.04 and 16.04, Qtractor, Carla, DISTRHO-Ports, CALF-Plugins - all compiled from git.

I installed Debian 9 now and added the KX repositories. Qtractor now uses QT5 instead of QT4. Anyway ... Calf Plugins still make Qtractor crash.
Maybe the only solution is to built everything from scratch. However I don't see why that makes any difference.

Are you sure that you got CALF plugins from KX repos, too? Maybe you should deinstall/install them.

I deinstalled the git-calf plugins and installed kxstudio4 calf package (2:0.90.0-1kxstudio4). Both packages are from the KXStudio repos.
Still the same. As soon I activate the Calfs own GUIs in Qtractor it crashes. This happens with all calf plugins.


Here's also a bug report at the calf git page: https://github.com/calf-studio-gear/calf/issues/181

I compiled QTractor and now all Calf plugins work. Don't know what was wrong with it.
Now I can load the plugins, but still it crashes sometimes.

Wow ...I wonder that nobody complained before. When is the new version available in the KX repo?

I am the one to be blamed a bit for my lazyness. I should have reported this earlier instead of using a workaround.

please don't rely on qt4 for much longer folks

upstream support for qt4 builds will vanish entirely by the end of the current year if not before--this applies to all qstuff not only qtractor.

Qt4 is dead! please move to Qt5 while you can--you should have moved for good three years ago!

you've been warned :)
cheers
