Moises

Moises turns a finished song into a practice track. Upload an audio file, mute the part you want to play, slow the song down, change its key, and add a click without opening a DAW.

Stem Separation handles vocals and common instruments including drums, bass, guitar, piano, keys, and strings. The exact choices depend on the plan and separation model. Once processing is finished, each stem gets its own volume control. You can mute the original part, loop a difficult section, or export the stems for another project.

The practice tools are what separate Moises from a basic vocal remover. Chord Detection follows the song as it plays. Smart Metronome builds a click track around tempo changes instead of forcing the recording onto a fixed grid. Speed Changer slows difficult passages without changing pitch, while Pitch Changer moves the song into a more comfortable key. Automatic lyrics, setlists, count-ins, and section looping make the mobile app useful at rehearsals and lessons.

Moises runs in a browser and has apps for Windows, macOS, iOS, and Android. The current desktop requirements are Windows 10 or later, or an Apple Silicon Mac running macOS 11 or later. Intel Mac and Linux users can use the web app, but do not get the same native desktop setup.

Pro subscribers get the Moises Stems plug-in for major DAWs including Ableton Live, Logic Pro, Pro Tools, Reaper, and FL Studio. It can separate up to seven stem types and lets you drag the results into the project timeline. Processing happens in the cloud, so the plug-in needs an internet connection and is not a real-time splitter. AI Mastering is available through the web and desktop apps. Moises AI Studio adds generated or replacement instrument parts, though this sits beside the practice workflow rather than improving the original separation.

The free plan allows five uploads per month, with a five-minute limit for each track. Chord Detection, lyrics, and Smart Metronome only analyse the first minute. Premium and Pro raise the track limit to 20 minutes and remove those analysis limits. Paid use is described as unlimited, but the fair-use policy treats regular processing above 14 tracks per day or 420 per month as abnormal use.

Separated stems are estimates, not recovered multitracks. Cymbals, room sound, reverb, and distorted instruments can bleed across the results or produce a phased, underwater edge. That is usually acceptable for practice, transcription, rehearsal tracks, and rough remixes. It is less convincing when a supposedly isolated stem needs to sit naked in a final mix.

Moises is the better choice for musicians who want to learn or rehearse a song. LALAL.AI puts more emphasis on separation choices and offers offline processing on its Pro tier. Neither replaces a proper multitrack session, regardless of what the waveform animation suggests.
