Tremo review
A focused web tool for melody transcription, piano conversion, and stem separation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tremo is a web-based AI music transcription tool from FLATMUSIC Inc. It converts uploaded MP3 or WAV files and YouTube links into sheet music or MIDI, with modes for simple melodies and piano melodies. Piano transcription includes controls for harmony, rhythm, and note duration. The service also targets audio-processing workflows through vocal, instrumental, and full-stem separation. It is suited to musicians, creators, and teams that need a focused way to turn recorded material into editable notation or separated audio.
The plan structure scales by conversion capacity and track length. Free includes 20T, tracks up to 3 minutes, Audio to Sheet PDF export, piano and voice MIDI conversion, and all audio-separation modes. Light provides 200T per month, all features, tracks up to 5 minutes, and all export formats. Pro raises the allowance to 500T per month and supports tracks up to 15 minutes. Studio adds 2,000T+ per month, team account management, bulk conversion, custom contracts, and no track-length limit. This makes the free tier useful for short, focused work, while larger projects and team workflows align with higher plans.
Tremo’s strongest fit is a browser-based transcription workflow that combines notation, MIDI, stem separation, and playback in one service. Users can preview MIDI piano-roll playback and separated-audio waveforms, then export PDF, MusicXML, MIDI, or separated audio files where the plan and conversion mode support them. Its narrow focus is also a constraint: the published platform is web-only, and track limits apply to Free, Light, and Pro. Choose Tremo for simple melody transcription, piano-oriented conversion, and stem-based processing; choose an alternative if native desktop or mobile access is essential.
