* This is the row/column that will appear in the soft row slot. A soft row position can be deassigned by setting
both row and column to 0x0f. The number of rows and columns is dependent on the current algorithm
(obtainable from a matrix dump, or from the documentation.) Slots in the Patch row cannot be assigned
to the Soft Row.
