A lightweight, open-source mixer GUI for Focusrite Scarlett USB audio interfaces on Linux. Built with Free Pascal and Lazarus, it gives you full control over your Scarlett's internal DSP mixer without needing Focusrite Control or Wine.
What it does:
It talks directly to the ALSA driver — every mix bus volume, input setting, routing enum, and hardware switch is exposed in an organized tree view with collapsible categories. You get real-time hardware level meters with peak hold and clip detection, reading straight from the Scarlett's onboard DSP at 20Hz. Volume controls, boolean switches like 48V phantom power and Air mode, input routing — it's all there.
Why it exists:
Focusrite doesn't ship a Linux version of Focusrite Control. The kernel ALSA driver (snd-usb-audio with the Scarlett mixer quirk) exposes all the controls, but running amixer commands by hand with 50+ controls is painful. This puts a proper GUI on top of it.
Requires:
sudo apt install alsa-util
