## About
|
|
|
|
<img src="src/img/alsa-scarlett-gui-logo.png" align="right">
|
|
|
|
The Focusrite USB audio interfaces are class compliant meaning that
|
|
they work “out of the box” on Linux as audio and MIDI interfaces
|
|
(although on Gen 3/4 you need to disable MSD mode first for full
|
|
functionality). However, except for some of the smallest models, they
|
|
have a bunch of proprietary functionality that required a kernel
|
|
driver to be written specifically for those devices.
|
|
|
|
Linux kernel support (the “ALSA Focusrite Scarlett2 USB Protocol Mixer
|
|
Driver”) for the proprietary functionality was first added in:
|
|
- Scarlett Gen 2: Linux 5.4 (bugs fixed in Linux 5.14)
|
|
- Scarlett Gen 3: Linux 5.14
|
|
- Clarett+ 8Pre: Linux 6.1
|
|
- Clarett 2Pre/4Pre/8Pre USB, Clarett+ 2Pre/4Pre: Linux 6.7
|
|
|
|
Unfortunately, actually using this functionality used to be quite an
|
|
awful experience. The existing applications like `alsamixer` and
|
|
`qasmixer` become completely user-hostile with the hundreds of
|
|
controls presented for the Gen 3 18i20. Even the smallest Gen 3 4i4
|
|
interface at last count had 84 ALSA controls.

The GUI supports all features presented by the driver (if not, please

report a bug).
