# alsa-scarlett-gui(1)

Gtk4 GUI for the ALSA controls presented by the Focusrite Scarlett/Clarett kernel driver

## NAME

	**alsa-scarlett-gui** - Gtk4 GUI for the ALSA controls presented by the Focusrite Scarlett/Clarett kernel driver

## SYNOPSIS

**alsa-scarlett-gui** \[*FILE*\]

## DESCRIPTION

	**alsa-scarlett-gui** is a Gtk4 GUI for the ALSA controls presented by the Linux kernel Focusrite Scarlett Gen 2/3/Clarett USB/Clarett+ Mixer Driver.

	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 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 ("ALSA Focusrite Scarlett Gen 2/3 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: coming soon

## OPTIONS

	*FILE*\
 		Load the specified .state file on start

## BUGS

- •

  The linear-dB scale of the volume controls doesn't work well. Lower volumes (e.g. below -30dB) don't need as much fine control as higher volumes.

- •

  Can’t select (focus) the gain/volume controls or use a keyboard to adjust them.

- •

  Level (monitoring) doesn't work yet and is disabled (needs kernel driver update).

- •

  Load/Save uses alsactl which will be confused if the ALSA interface name (e.g. USB) changes.

- •

  Load/Save is not implemented for simulated interfaces.

- •

  Lots of "couldn't find weak ref" warnings are emitted when loading a state file for simulation.

- •

  The read-only status of controls in interface simulation mode does not change when the HW/SW button is clicked.

- •

  When there's more than one main window open, closing one of them doesn't free and close everything related to that card.

- •

  There is no facility to group channels into stereo pairs (needs kernel support to save this information in the interface).

- •

  There is no facility to give channels custom names (needs kernel support to save this information in the interface).

- •

  No keyboard accelerators (e.g. Ctrl-Q to quit) have been implemented.
