Build this sliders-and-keyswitches input device to speed up your photo color grading workflow!

Adobe Lightroom Classic can be controlled via MIDI messages, giving you quick access to essential processing controls. It's a snap to adjust fundamental photo developing parameters such as exposure, color temperature, contrast, and saturation with the handy sliders. Use the keys to swap photos, and pull up the crop and heal tools.

Or, use it for any MIDI-capable application or host device, such as synthesizers, mixers, and more.

This project can be expanded to use more buttons and sliders by adding additional STEMMA QT boards with unique addresses, then making adjustments to the code.
