Linux Driver for Focusrite Scarlett Gen 4

Edit: A massive thank you to the incredible Linux Musicians community and all my supporters — this fundraiser was a resounding success! With the target reached now, I've ended the GoFundMe campaign.

Help me bring the newest Focusrite Scarlett (and Vocaster and Clarett!) interfaces to Linux!

Hi, I'm Geoffrey, and I'm the author of the Linux Focusrite Scarlett Gen 2+ mixer driver and GUI.

Back in 2018 I purchased a Focusrite Scarlett 18i20 2nd Gen audio interface. While these interfaces work well “out of the box” on Linux, they have extra functionality that is controlled through a proprietary protocol. At that time there was no Linux support for this functionality, but being a curious Linux/programming geek I spent months staring at USB protocol dumps to reverse-engineer the proprietary interface, and developed a Linux kernel driver so any Linux user with one of these could access the full functionality of their device.

Five years later, the driver supports 11 [Edit: now 13] different models of Focusrite Scarlett and Clarett interfaces, and we have a nice GUI as well.

Getting to this point has been a significant investment as it's difficult to develop without the hardware in front of me. Except for a generously donated 4i4 3rd Gen, I've personally acquired one of every Scarlett Gen 2/3 model to develop against and make sure that everything works and continues to work as well as possible.

Focusrite have recently released 3 new "4th generation" models, the Solo, 2i2, and 4i4, and I would like to add support for those. I'm reaching out to ask for your financial support to do this.

Raised funds (from the initial goal of $1,133) will go towards:
  • Solo 4th Gen: AUD$205 ✅ (have this, working on it now)
  • 2i2 4th Gen: AUD$299 ✅ (have this, working on it now)
  • 4i4 4th Gen: AUD$439 ✅ (have this, working on it now)
[Edit: have these all now, and have decoded nearly everything that needs to be decoded. Will have a driver soon! Please contact me by email if you can participate in pre-release testing.]

Any extra funds raised will go towards purchasing the other remaining Focusrite interfaces which are not yet supported: the Vocaster One and Two [Edit: the Clarett+ 2Pre and 4Pre are now done!].
  • Vocaster One: AUD$189 ✅ (been pledged, coming soon)
  • Vocaster Two: AUD$379 ✅ (been pledged, coming soon)
  • Clarett+ 4Pre: AUD$989 ✅ (this is done now!)

I'll provide updates on my development progress at in the Computer Related Hardware forum.

While donations are incredibly appreciated, sharing this with others can be just as helpful.

Thank you!
