# ALSA Scarlett Control Panel (`alsa-scarlett-gui`) v1.0 beta

A Linux control panel for Focusrite Scarlett, Clarett, and Vocaster
USB audio interfaces — the equivalent of Focusrite Control /
Scarlett MixControl / Vocaster Hub on Linux.

Configure routing, mixing, input/output levels, DSP processing,
and firmware updates through a graphical interface.

This is a beta release — better than 0.5 but not quite 1.0. The
docs still need some updating.

## Supported Interfaces

- Scarlett 1st Gen 6i6, 8i6, 18i6, 18i8, 18i20
- Scarlett 2nd Gen 6i6, 18i8, 18i20
- Scarlett 3rd Gen Solo, 2i2, 4i4, 8i6, 18i8, 18i20
- Scarlett 4th Gen Solo, 2i2, 4i4, 16i16, 18i16, 18i20
- Clarett 2Pre, 4Pre, 8Pre USB
- Clarett+ 2Pre, 4Pre, 8Pre
- Vocaster One and Vocaster Two

## Donations

This software — the Linux kernel driver, this control panel, and the
documentation — represents over a thousand hours of independent
development: reverse-engineering Focusrite's USB protocols,
developing and upstreaming the kernel driver, and building a
complete replacement for Scarlett MixControl, Focusrite Control,
Focusrite Control 2, and Vocaster Hub — often providing more
functionality than Focusrite's own software.

If you've found it valuable, a donation is a nice way to say thanks:
