New UR824 linux driver and ur824ctl tool


Last month I recorded my first real gig using the Steinberg UR824 and a Behringer BCF2000 with ardour3 under Linux, and it was perfect. Glitch free as far as I can tell, and the functionality was just as I needed.

The picture shows the ardour3 mixer, with one of its PFL buttons proudly illuminated. Why proud? Because this wass one of the wonders of going the Linux route, I was able to get true PFL functionality and modify the setup so it worked exactly as I wished when I pressed the buttons on the BCF2000 control surface.

Now of course nothing in the open source world is guaranteed, but if you'd like to try it, I've uploaded a new version of the driver to the installation page. I've also uploaded a new ur824ctl tool, that allows you to control the routing inside the UR824 in a top-down kind of way. All comments/encouragements gratefully received at code@deodar.org.uk

Patching the alsa snd-usb-audio module using alsa sources

On modern Linux boxes, the alsa modules are part of the kernel, in which case you shouldn't need the recipe described here. However, if you need to patch alsa on a machine where alsa is not part of the kernel, or can't rebuild the modules within the kernel for some reason, the following instructions might help.

Get the package of alsa drivers from the alsa project, unpack it, and build it:

Pre Fade Listen (PFL) in DAW software - Ardour v Cubase - and which is really free?

I bought my Steinberg UR824 in the hope of getting it to work with Linux, and on the basis that in the mean time I'd have to let go of Ardour in favour of the version of Cubase AI with which it is bundled.

In this article I want to talk about monitoring. I come from the background of using live desks, mostly for broadcast, where you need the concept of Pre Fade Listen (PFL) rather than Solo. WIth Solo, the effect is to mute all the other channels, so the mixes are all affected. With PFL, the selected channel is routed to your headphones or monitoring speakers, but all the mixes stay as they are.
