About The ONE
The ONE (TheONE Music) makes smart musical instruments built around learning: smart pianos and smart electronic drums, each paired with a companion app. The company states its mission as empowering people of all ages to learn and enjoy music through technology, and its range spans portable keyboards and home pianos, drum kits, and matching accessories.
The TRD 9-Pad Roll-Up Drum Kit brings that approach to the beginner drummer. It rolls up for storage, plays through dual built-in speakers, and ships with access to the InstaDrum app, which carries video lessons, rhythm games and notation-reading exercises. A rechargeable battery gives over eight hours of play, and a pair of pedals and sticks come in the box.

Why we recognized The ONE
The House of Octave Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose gear consistently stands out in our player-tested category guides. The ONE earned it on the strength of the products below, judged the same way every product on this site is: assessed on build, tone, and playability, weighed against what players actually report over years of use, and ranked on merit.
The ONE gear we rated highly
The ONE TRD 9-Pad Roll-Up Drum Kit
It comes with a way to learn as well as something to hit: access to the InstaDrum app brings video lessons, rhythm games and notation-reading exercises, which suits a household where nobody plays drums yet. The layout of five drum pads and four cymbal pads, plus two foot switches, sits close to a real kit, and dual built-in speakers let a child hear the difference between drum and cymbal voices. It is rechargeable with over eight hours of play, weighs about two and a quarter pounds, and includes sticks and two pedals, for beginners aged 6 to 12.
