Hi everyone — Tutti 1.8.0 is now available.

This release adds Display Control on macOS 15 or later. You can select multiple displays and adjust their brightness together or individually using the brightness keys, custom shortcuts, or scrolling.

External displays can follow the built-in display while keeping their own brightness offset, and presets can now remember display selection and brightness alongside your audio setup. With Tutti Remote 1.1.0, you can also control individual displays or the whole group from your iPhone.

On the audio side, Stereo Mode has been improved on macOS 14.4+: assigned left and right speakers keep their roles, while any additional selected outputs play full stereo instead of going silent.

If you try it with a particular display and speaker setup, I’d be glad to hear how it works for you.
