# Scarlett MixControl: rebuilding control of first-generation Scarlett interfaces

> Scarlett MixControl replaces Focusrite's MixControl 1.10.6 on modern macOS for first-generation Scarlett interfaces. The Swift app exposes matrix mixing, output and capture routing, metering and presets through USB control requests. Its command mapping comes from signal tables extracted from the original application and disassembly of routing functions.
