Overview
ハッピーシンセサイザ (Happy Synthesizer) is a VOCALOID original song by producer EasyPop, featuring GUMI and Megurine Luka on vocals. Released to NicoNico Douga in 2010, the track became a staple of the early VOCALOID canon, a bright, mid-tempo synth-pop tune built around a warm melody and a recurring synthesizer hook at 127 BPM. Its lyrics, delivered in a call-and-response between the two vocal synthesizers, play on the metaphor of a "happy synthesizer" as an instrument that can transmit honest feelings and dissolve everyday frustrations through music.

Trivia
- ハッピーシンセサイザ was part of maimai's original launch lineup on July 11, 2012, making it one of the oldest songs in the series.
- The original maimai cabinet featured a full choreography video for the song, with dance moves performed by NicoNico dancer めろちん (Merochin). Playing the Standard BASIC chart without mirror mode reverses the choreography; enabling the mirror setting in the game's options realigns the player's movements with the original video.
- Starting with maimai でらっくす (maimai DX), the choreography video was replaced with a static jacket image. The original jacket art was a screenshot from the dance video, while the DX version switched to a newly illustrated key visual.
- In Asian English releases of maimai, the song's title is displayed as HAPPY SYNTHESIZER.
