Frequently asked questions
Everything we get asked about ArrangementLabs.ai. If something's missing, email hello@arrangementlabs.ai.
What is ArrangementLabs.ai?
ArrangementLabs.ai is an AI-powered music arrangement service that converts musical scores between any instrumental configurations. Upload a score in ABC, MusicXML, MXL, or MIDI format, pick an ensemble preset, and download MIDI, MusicXML, and PDF outputs in minutes.
What input formats does ArrangementLabs.ai support?
MusicXML, MXL, MIDI and ABC, as well as PDF scores. A scan is read automatically and the result is shown for you to check before arranging.
What output formats does ArrangementLabs.ai produce?
Every arrangement is delivered as MIDI for further editing in a DAW or notation software, MusicXML for cross-tool interoperability, and PDF for sheet music distribution.
What ensembles can ArrangementLabs.ai arrange for?
String quartet, string trio and string duo; duos for voice, violin, flute or bassoon with piano or accordion; a trio for voice, violin and piano; solo piano and solo accordion. The source can be a solo piece or a multi-part one, for example piano rewritten for quartet, or quartet for piano.
How is the arrangement created?
ArrangementLabs.ai uses proprietary AI technology developed in-house for cross-ensemble musical arrangement. The system analyzes the source score and redistributes musical voices across the target ensemble while preserving the musical intent of the original.
Is the arrangement output editable?
Yes. The arrangement opens in a notation editor in your browser, where you add, move and delete notes (from the keyboard, the screen or a MIDI instrument) and hear the changes straight away. You can also download MusicXML and MIDI and open them in MuseScore, Sibelius, Dorico, Finale or a DAW. The PDF is ready to print.
Who is ArrangementLabs.ai built for?
ArrangementLabs.ai is built for arrangers, composers, music educators, conductors, performing ensembles, and music publishers who need to adapt existing scores between different instrumental configurations.
How does ArrangementLabs.ai compare to other AI music tools?
Most AI music tools generate music from scratch (Suno, AIVA, Soundraw). ArrangementLabs.ai is purpose-built for arrangement — taking an existing musical work and adapting it to a different ensemble while preserving the original musical content. The workflow centers on score-in, score-out at high fidelity.
Is ArrangementLabs.ai a replacement for Finale?
For engraving, no, and we say so plainly. MakeMusic ended Finale's development and pointed to Dorico as the transition path; if you are looking for an engraving program, that is Dorico, Sibelius or the free MuseScore. ArrangementLabs.ai replaces a different part of that work: rewriting a piece by hand for another ensemble. You upload a score, get an arrangement for the ensemble you picked, edit it in the notation editor in your browser, and export MusicXML into whichever program you use for casting off and engraving.
Do I need to install a notation program?
No. Uploading the score, choosing the ensemble, arranging, editing notes, listening and downloading the files all happen in the browser, and the computing is done on the server. A notation program comes in when you engrave the score and parts for print. Then you download the MusicXML and open it in Dorico, Sibelius or MuseScore.
Can I try the editor without an account?
Yes. The notation editor does not ask you to log in. You choose an ensemble and write on a blank score, or open your own MusicXML file. The score stays in your browser and you download the finished one as MusicXML. During the beta an account is only needed to arrange for a different ensemble.
