Moises: The Musician's App

Remove vocals or instruments

With this AI-powered app, musicians can perfect their performances by playing alongside the best bandmates ever – the original artists.

– App Store Editors

Ever wanted to sing lead vocals, unleash a guitar solo or play bass with your favourite band? This AI-powered wonder can isolate individual instruments in pretty much any recording to let a new star take the stage: you.

Moises’ elegant, pared-down controls make it easy to access the power of AI to supercharge your practice.

Start by importing an audio file you’ve purchased from the iTunes Store (or recorded yourself), then choose how you want to break down the song. Moises can separate the vocal into its own track. Instrumentalists can go further. Isolate the piano, bass, strings or woodwinds. Split out the rhythm and lead guitars. Even distinguish between each element of the drum kit, soloing just the snare, toms, hi-hat, cymbals or kick drum.

Moises also uses AI to generate chord charts and transcribe lyrics (it successfully deciphered more than a few mumbled lines we’d always wondered about). When we changed the key or slowed down the tempo to make a song easier to play, AI kept that shift largely transparent. And when the app’s Smart Metronome added a steady click for us to keep time with, it adapted seamlessly to all the subtle tempo changes in the performances, no matter how dramatic.

AI played a subtle part elsewhere in the app, such as the ease with which you can loop sections of a song for targeted practice. Because Moises can identify where verses, choruses and instrument solos begin and end, you can repeat any (and in any combination) with a tap.

This year, AI revolutionised creativity in all sorts of ways. With Moises, it also helped us play among the stars.

Quick tip

With the Live Recording feature, you can have Moises analyse your own compositions – even rough demos you record in your bedroom. Just sing and strum, let the app upload the audio for processing, and see a breakdown of the chords you sang and the chords you played.

Fun fact

When drummer Eloy Casagrande got a call to audition for the heavy metal band Slipknot earlier this year, he had to learn 32 songs in a matter of days. So he let Moises take the lead. Casagrande used the app to dive into key parts of the songs, optimising his practice with the app’s loops and instrument isolation. In April, Slipknot announced Casagrande as its new drummer.

Meet the creator

Brazilian developer and drummer Geraldo Ramos began coding as a teenager with his longtime friends Eddie Hsu (a violinist) and Jardson Almeida (a singer). Moises was inspired in part by “the challenge that we didn’t always have enough musician friends to form a full band,” Ramos says. Bringing together their love of coding with their passion for music, the three launched Moises in 2019.
