02 — METHOD
Not a generator. An arranger.
ArrangementLabs doesn't create new music — it arranges yours. It builds each voice from scratch, adapting it to the range and character of the instrument. You set the direction — describe what you want to change, and ArrangementLabs adjusts.

What musicians say.
I.
Automatic conversion of a score to any instrumentation — keeping it musically correct and ready to perform immediately — is a breakthrough for anyone who works with live music.
II.
For ensembles like ours, it means less time spent on arranging and faster delivery of our programme plans.
III.
The tool doesn't replace the creator — it supports their creativity, letting them develop the generated ideas with their own artistic solutions.
IV.
The arrangement preserves the harmonic logic and character of the original — not creating a new composition, but a functional performance version.

06 — FAQ
Got questions. We have answers.
Which ensembles does the beta support?
The beta supports a dozen-plus presets across four families: strings (quartet, trio, duo), piano duos, accordion duos, and solo instruments. Input formats supported: ABC, MusicXML, and MIDI — the model arranges to your chosen ensemble in 4/4, 2/4, and 3/4 time signatures. More presets are added gradually.
Can I edit the generated arrangements?
Yes. The output is available as MusicXML — open it in MuseScore, Sibelius, Finale, or any other notation software. You can also iterate directly in ArrangementLabs using prompts: describe what you want to change and the model adjusts. Direct note editing in the app is planned for the future.
Does the tool replace my artistic choices?
No — the model proposes, you decide. ArrangementLabs builds each voice from scratch while trying to preserve the character of the original, but the final decisions are always yours. Iterate with prompts until it's right, or edit the output manually in your notation software.
What file formats can I upload?
ABC, MusicXML, MXL, and MIDI — up to 10 MB. If you have a PDF score, convert it first using MuseScore or Audiveris. PDF and audio file support is planned for the future.
Is it free during beta?
Yes. Beta testers get full access at no cost. We'll announce pricing well before the beta ends.
Invitations are limited. Leave your email — we review applications and reply with a decision.
