Use the Type selector to determine what will be mapped over the pads:
Notes: Each pad is assigned a note, ascending by one scale degree with each pad.
Chords: Each pad is assigned a chord, the root note ascending by one scale degree with each pad. All available
chords will play in the key determined by the Scale.
Chromatic Chords: Each pad is assigned a chord, the root note ascending by one scale degree with each pad.
You can play any chord type regardless of the key determined by the Scale. Essentially, this is like the Chords
setting but with more options to play chords out of the set key.
Progressions: Each pad is assigned a chord in a chord progression. You can play the pads in (or out of) order to
construct songs quickly. The available chords are determined by the Chord field.

Use the Scale & Octave fields to determine the root note and the scale type.
Root Note (pitch and register): This is the starting point of the scale. The available notes are all chromatic notes
across the range of the pads. The pad that's assigned the root note will be lit differently (and highlighted in the
touchscreen) to indicate where the scale starts in each octave.
Scale Type: This is the scale or mode based on the root note (this is disabled when Type is set to Progressions).
The available scales are:
Major
Minor (melodic)
Pentatonic Major
Pentatonic Minor
Blues (minor)
Flamenco
Gypsy Dorian
Hungarian Gypsy Phrygian
