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.

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.
