A Solo Frame in QLC+ enforces mutual exclusion so only one button is active at a time

A Solo Frame is a Virtual Console container that ensures only one child Button can be in the ‘On’ state simultaneously. When Button B is activated, Button A is automatically released. This is the standard solution for exclusive scene selection — pressing one colour should cancel the previous one without manual management. Boundary case: ‘Mix sliders in playback mode’ relaxes exclusivity for playback sliders, letting them coexist and cross-fade (a raised slider fades others out at the same speed) rather than instantly cutting.

Examples

Eight colour-wash buttons in a Solo Frame: pressing ‘Blue’ automatically stops ‘Red’. Useful for scene preset banks on a MIDI grid controller.

Assessment

Why use a Solo Frame rather than a normal Frame for a bank of scene-select buttons? What does ‘Mix sliders in playback mode’ do and when would you enable it?
