# ALSA Scarlett2 Control Panel (`alsa-scarlett-gui`) `alsa-scarlett-gui` is a Gtk4 GUI for the ALSA controls presented by the Linux kernel Focusrite Scarlett2 USB Protocol Mixer Driver. Supported interfaces: - Scarlett 2nd Gen 6i6, 18i8, 18i20 (the smaller interfaces are controlled with physical buttons only) - Scarlett 3rd Gen Solo, 2i2, 4i4, 8i6, 18i8, 18i20 - Clarett 2Pre, 4Pre, 8Pre USB - Clarett+ 2Pre, 4Pre, 8Pre ## About 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 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. Announcing the ALSA Scarlett Gen 2/3 (and Clarett USB/Clarett+!) Control Panel! ![Demonstration](img/demo.gif) The GUI supports all features presented by the driver (if not, please report a bug). ## Documentation Refer to [INSTALL.md](INSTALL.md) for prerequisites, how to build, install, and run. Refer to [USAGE.md](USAGE.md) for usage information and known issues. ## 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. - https://liberapay.com/gdb - https://paypal.me/gdbau ## Scarlett Gen 4 Support Focusrite recently released 3 new “Generation 4” interfaces: Solo, 2i2, and 4i4. The first draft of kernel support is available here: https://github.com/geoffreybennett/scarlett-gen2/releases/tag/v6.5.11-g4.1 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. ## License Copyright 2022-2024 Geoffrey D.
