In the off chance anybody from Rode sees this: This makes me want to purchase your gear. Don't change it. It's funny this comes up now. Tomorrow I'm dragging my Zoom R20 recorder on-site to use as an overly-featured USB audio interface for a single-mic live stream. If I'd know this about Rode a week ago I'd have purchased one of these and could have left my R20 hooked-up in the home studio!

I’m guilty of using my Zoom R16 in a similar fashion; as USB audio interface most of the time for a couple of inputs. The only thing that is a little sad about it is that for example the faders do nothing when the R16 is in USB audio interface mode. It does however like to randomly turn on reverb and one other effect after power cycling. Which I sometimes forget and then wonder for half a second why the audio is soun…

Interesting.

I'm running my R20 in USB interface / stereo mix mode and the faders do work. I didn't think about trying to apply any effects. I'll play with that, for fun, but I'd definitely add them in the DAW as well. (I really only use my R20 for multitrack recording and do all my effects in the DAW. I like it, and it can do a ton standalone, but my workflow really just needed a multitrack recorder and I could have probably spent a lot less. It just looked like fun...)

I really want to know how he solved this problem, which I also face: >last year i bought a Rodecaster Duo to solve some audio woes to allow myself and my girlfriend to have microphones to our respective computers when gaming together and talking on discord in the same room without any echo

the rodecaster can connect to two computers, and we are both generally in the same discord call. so we have both microphones routed into one input for a computer, and the other person joins with their mic muted and the audio just comes from one client. since the mixing is local there's no echo. email me if you have more questions :)

I get it! Thank you that is genius.

Having the firmware image just be a boring old tarball + hash sounds super nice. I wish more devices were this open, and I hope Rode won't see this and decide to lock the firmware upgrades down.

I had to upgrade the firmware in my HP printer a couple years ago. It’s a printer that I think was released in ~2009 (I am not able to check right now), and in order to upgrade the RAM to 256MB I needed to do a firmware update. I dreaded this, but then I found out that all you do to update the firmware was FTP a tarball to the printer over the network. I dropped it in with FileZilla, it spent a few minutes whirring,…

I think my favorite is wifi access points that support tftp to load a firmware image (with some kind of hardware switch to enable this state). These can be made effective unbrickable and it's really nice for experimenting.

Cyber Resilience Act [1], which is well-intentioned, and doesn't outright forbid user access to firmware, but most vendors will take the easy road and outright block user-modifiable software (if they didn't already), so that their completely closed source, obfuscated and vulnerable version is the only version allowed on their devices. [1] https://en.wikipedia.org/wiki/Cyber_Resilience_Act

Ah, EU-only. That explains why I've never heard of it, among other things.

Well... if you look behind anything that plugs into a wall socket you will see that it has ( among many other things) a CE mark. Even things in the USofA have a CE mark.

If your new product cannot have its CE mark for whatever reason, you will not have the approbations to sell in the USA either.

What the CRA will do, is if you do not have a "CRA" compliant product, you will not have the CE mark. Which means you will not (with very high probability) have the other marks needed to sell outside Europe.

Maybe then you can just sell to your close family members who like you, but good luck if you get caught and it can be proven that your shitty device caused a fire ...

The last one was 8 years ago. It's not a terribly common vuln anymore - not that it ever was.

Not true. There's way more than that list. I could immediately think of 2 more from last year: CVE-2025-22224 and CVE-2025-22225

I think "my audio interface is a 64-bit Linux computer" would've sounded far more interesting to me as a title. Perhaps a decade or two ago, the functionality of that device would've likely been implemented on a small 16-bit or 32-bit SoC running an RTOS like VxWorks.

Given how many physical controls it has, turning it into a game console seems like a logical next step.

Its still crazy to me that everyone has a pocket AI-hacker ready to inspect firmware and modify their devices now. You just put the agent on it and it gives you access in minutes. You would have to be a Hotz tier hacker if you wanted to do anything close to this only last year, or at the very least extremely patient for long hours.

If it’s embedded Linux with no HAB it’s not hard to make “adjustments.” Just use file and binwalk to figure out what it is and break it open.

I think it should be locked down to require some kind of physical button input to enable the commands, putting it in some kind of "DFU" mode. Otherwise anything with USB access could brick your device by flashing a bad firmware.

Whose security are we talking about here? Mine, or the manufacturer's?
