" The First Sound" ( ハジメテノオト, Hajimete no Oto ?) The game contains a total of 30 playable songs (not including " Ievan Polkka" as the tutorial), six of which are medleys and two which return from previous entries in the Hatsune Miku: Project DIVA or Project Mirai series.

The game also has a traditional game mode, under the title "Free Play".

All rhythm game quests require a specific amount of Voltage (replacing the traditional score) to clear it. There is a new gameplay mode, known as Live Quest which is a story mode where the player completes a series of rhythm game quests in each song of all five Clouds. The "Linked-Star notes" and "Double Star" notes that were introduced in Hatsune Miku: Project DIVA F 2nd have been removed. DIVA X introduces a Rush Note, where after hitting the note regularly, the player can then tap either of the buttons that correspond to that note as quickly as possible to gain bonus points within a short amount of time. Like every other game in the series, the player taps the directional and PlayStation action buttons (Cross, Circle, Triangle and Square) that correspond to the displayed button and flicking either stick or swiping the PS Vita's screen/DualShock 4's touchpad for Star notes to the beat of various songs. It showed the full PV of "Raspberry*Monster" revealing the confirmed artists/producers involved in providing the songs in the game. The game was revealed on Augon Hatsune Miku's 8th anniversary.
