Roland Rubix sound cards

I just found out about the new Roland Rubix 24 sound card. It's USB audio class compliant and all the functionality is controllable with knobs and switches on the hardware, so it should be fully compatible with Linux. I haven't heard one of these myself, but the specs look on par with the Focusrite Scarlett 2i4 so I presume it sounds quite good. For the same price as the Scarlett 2i4, this has a few neat advantages. It has a hardware compressor for the inputs, so the inputs can be compressed while using direct monitoring. Plus, it can also run standalone from USB power (a cell phone charger) without a computer. I think this will be the sound card I generally recommend now (and not just for Linux users).

There's also the Rubix 22 with 2 less outputs and no hardware compressor and the Rubix 44 with two more inputs.

Has anyone tried these? Were there any quirks setting it up with Linux or was it plug-and-play? How do they sound?

I have the same question 'bout the Behringer 404HD. It's cheaper and also has multiple out via USB. Might that be an alternative for you?

Behringer makes bad sounding gear that breaks quickly. That's why it's so cheap.

I'd contest this. It may be true in many cases, but we use an X32 mixer which we are dearly in love with. It's a great live mixer and tons of bang for your buck. The Midas style preamps sound very clean and neutral and we use them for recording with great success (albeit nowdays with additional character preamps in front on some channels). The build quality seems good, we have the mixer for 3-4 years and it still has to fail us.

Certainly even if designed by Midas it won't be the same quality, but one would really have to work hard to find fault with it.

If it's a class compliant device then it should be plug and play. I reckon this device is kind of the successor to the UA-25(EX), those were awesome so I bet these Rubix interfaces are great too.

Behringer has made a lot of crap (remember those cheap platsic guitar stomp boxes?) but they also make very sturdy, good sounding gear. I've got a BCR2000 and a BCF2000 and those are still great devices. Recently I bought an ADA8200 which is just so much bang for the buck, almost unbelievable.

I just got a rubix44 and it works fine on linux. All switches hardware. Coming up as standard audio device and I seem to have all possible sample rates and resolutions available. Not much to report yet except one minor annoyance: it will stay awake for 10 hours after the computer turns off with a bright light blinking away. The hardware off switch is tiny and hard to get to on the back. I guess roland thinks that pro-hardware people don't want their audio equipment to do an auto-shutdown...

Anyway, at this stage, I would definitely recommend this hardware for linux.

...the slightly more aggravating side of this 'feature' is that after ten hours the rubix44 goes to sleep and computer activity won't wake it. This means your jack autostart will fail. The solution is that you have to power off / power on using the poorly located manual switch. And take jack out of your autostart programs in case you forget to turn the unit on (or off and on again) before booting.

I still don't regret buying it. I am running it on 88000 or so MHz and I get 3-8% CPU use on my Ryzen 1700 mid range computer.

I had looked at the Behringer UMC1820, but although the bang for the buck looks great, I was put off by a previous experience with poor QC on their part. I think if you get a good piece of equipment, Behringer is a great buy, you just may have to go thru a return or two to get it. I'm trying the Rubix44 to replace my firewire interface, a Saffire Pro 24DSP. I'm still using the Saffire, but only on MacOS-based gear. It's just not worth the amount of time I've spent getting mediocre support for a legacy Firewire device on Linux.
