Hi @mihaimike1894, couple of things:
I’m assuming that the ultimate purpose of this “multi-slot” block would be to save space on grid. Otherwise, there’s nothing stopping you from placing multiple captures on the grid and switching them via Scenes.
Having a global set of controls for gain, bass, middle, treble, volume, etc., for multiple captures would get weird and wonky pretty quick since we know that captures are… captured at different volume levels.
There is already a request for a multi-slot amp block that you’re suggesting, although your request is the first I’ve seen specifically for captures. This request has zero votes as I post this, though:
