TIL that for very flexible minimal-latency Input/Output routing of #audio signals, buying a (analog or digital) #mixer with multiple buses seems like the obvious choice, but there are also (USB) audio interfaces which support internal routing! For example #Arturia’s #AudioFuse line, or the #RME #Fireface UCX. Once configured, they can even run without a computer. Some even have internal EQ & FX.

Now, is there one with internal #sidechain compression? I’d _love_ that. Any suggestions?

The Fireface UCX II comes pretty close, but its compressor can’t do sidechaining. However, I love some of the small details on that device, like labeling the DC input with an actual accepted voltage _range_. That’s so useful when deciding whether to connect it directly to my campervan’s 12 V supply (which is actually somewhere between 14.5 and 11.5 V).

They also support re-binding the front buttons to shortcuts. And it’s MIDI and OSC¹ controllable.

¹ via proprietary software only tho lol

I have a Behringer XR18, which needs 230 VAC to work (boo), is pretty chunky and eats a lot of power.

Also, while it _does_ have an internal sidechain compressor, it can’t use a submix as the trigger signal, only a single individual channel. Which sucks if you’re trying to trigger on several instruments or mics 🙄

@scy even the RME interfaces have simple compression per channel in the hardware/mixer layer. your next best guess is do it in a DAW but that does require you running the matrix in a DAW which is less cool and won't work if the computer is shut down..... or just buy a hardware unit :)

@ronald But the RMEs also have the “loopback” feature, which would maybe enable me to send a submix to an input channel and then (if they had sidechaining) use that as the trigger.

Maybe.

But no, I don’t want additional devices, I want it to be as small and portable as possible :(

@scy hmmmm that could indeed work, depends on where the comp looks for input. I am expecting the comp looks at input channel level from the hardware side but I'm sure RME would happily help you with this question! https://www.rme-audio.de/support.html
