Resize Lower Zone

How do I go about resizing the lower mix zone so that It’s height is reduced. I can put the arrow close to the boundary and drag down a little bit, but would like to reduce it even more. I see people on Youtube with this lower zone reduced, but after searching high and low have not been able to find an answer to that question.

It depends on your screen resolution and DPI Scaling as to how much of the vertical screen space the lower zone can be minimised down to, as it has to house the content for mixer, chord pads, editor, sampler elements.

It’s possible you’re comparing to users with a higher resolution, perhaps?

Maybe take a screenshot of your lower zone at it’s minimum height would provide more context?
