What are “bottom focus” and “top focus” variants?

The Line 6 Helix offers the ability to configure its ten primary footswitches in five ways:

  1. Bank up/down + eight patch selectors
  2. Bank up/down + four patch selectors on the bottom row and four FX on/off on the top row
  3. Bank up/down + four patch selectors on the top row and four FX on/off on the bottom row
  4. Bank up/down with eight FX on/off
  5. Ten FX on/off (with no bank up/down)

A patch with “top focus” puts the most essential effects control on the top row while a patch with “bottom focus” puts the most essential effects control on the bottom row. In many cases¬†using mode (4) above gives access to additional options. In some cases mode (5) may allow a few additional control options.
