The Reface series was announced on 7 July 2015 through an online event.
[1][2] The day before, the announcement was mistakenly leaked by Yamaha through a Korean website.
[5][6] The Reface series uses Yamaha's velocity sensitive "High Quality Mini Keys", the same keys as those of Yamaha's Motif XF.
[12] After their announcement, the Refaces drew comparisons to both the Roland Aira series and Korg's Volcas due to their affordability and inspiration taken from their respective companies' previously released synthesisers.
The robot was built in collaboration with the Fukuoka-based design company Anno Labs.
