Talk:愛のコントローラー (Ai no Controller)/@comment-26239285-20170419002904

BTW a "controller" is a control on a keyboard music synthesizer. Apart from what it's meant to sound like, apparently this song is actually about the composer's relationship with a musical instrument. He even made a video to show me that "sliding it up" actually refers to moving a knob on the control panel. Very clever.
