## About
@@ -16,64 +17,50 @@ Supported interfaces:
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
(although on Gen 3/4/Vocaster 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.

## Donations
This program is Free Software, developed using my personal resources,
over hundreds of hours.
If you like this software, please consider a donation to say thank you
as it was expensive to purchase one of each model for development and
testing! Any donation is appreciated.

Please contact me by email if you would like to help test.
## Vocaster Support
Vocaster One and Two support will be coming once I've completed the
Scarlett 4th Gen support.
