MatrixBrute stores 16 banks of 16 Presets (total 256). The banks are rows A - P on the left,
Presets within each bank are in columns 1-16. To select, say, patch B3, go two rows down
and three columns across; B 03 will appear in the numeric display.
(The Matrix is also used for the 64-step pattern sequencer/arpeggiator, and when you push
MOD it becomes the electronic patchbay.)
