Your MIDI keyboard will be divided into two pianos split at middle C. Each piano will have its own notes mapped to it, allowing you to have more than 12 notes to the octave. You can adjust the number of notes with the slider and adjust the mapping by dragging numbers to the desired keys. Click a key to remove a number.
Drag numbers to keys, then click keys to remove them
