It uses a Guitar Hero-esque method to improve your keyboard skills.
The system, which claims to make you "more musical in minutes," uses a Guitar Hero-style method to improve your keyboard skills. You pick a song from a currently undisclosed bank of tracks spanning "pop to classical," choose the part of the song you want to play, then the app displays coloured blocks that represent notes as the correct corresponding key illuminates on the keyboard. You can also tailor the playback speed of the track to fit your abilities and pause things altogether. As your skills improve, you can move from following coloured blocks to reading sheet music.
Unlike ROLI's Seaboard, the LUMI's keys resemble a traditional keyboard, are sized to fit the average human hand and offer "92 percent of the plunge distance of a grand piano key." It also does not support MPE, although it can function as a regular MIDI controller in a wide range of DAWs.
The Kickstarter has already been fully funded. The cheapest bundle is currently priced at $187, with an expected shipping date of October 2019.
