For example, if you select Custom Mode, and play a 1-b3-5-b7 chord, every key will then be assigned to play this chord structure. Smart Chord also has a Custom Mode which lets you determine the chord structure that will be assigned to each key by manually playing it. The rest of the chord’s properties (Major, Minor, and Voicing) are determined by the settings you choose. The key you press will determine the root note in the chord. With Smart Chord activated, pressing a single key will play a full chord rather than just one note. With Smart Chord and Smart Scale technology, creating music and unleashing your unlimited creativity has never been easier. The Smart Chord feature helps bring out your inner musical genius by playing full chords with a single key press, and with the Smart Scale feature, the Oxygen 49 (MKV) keys transform into a perfect scale, playing the exact notes within a chosen scale. Smart Chord and Smart Scale technology are the bridges between your musically creative mind and your final productions.
