Two ways to create

Start simple. Go deeper when the music matters.

Basic offers the familiar AI song-making experience at familiar prices. Advanced Accompaniment is the professional step up: it begins with a real performance, preserves its melody and expression, and writes a directed arrangement around it.

Advanced Accompaniment · premium control

Every suggestion remains editable.

A melody may support more than one good chord progression, so the studio suggests compatible harmonies instead of pretending there is only one correct answer. Pick a direction, rewrite it, or lock your own progression.

ACOUSTIC

Space around the performance

Natural percussion, bass, piano, acoustic guitar, and subtle texture.

Detailed drums, melodic bass, electric keys, guitar, and pads.

CINEMATIC

Emotion with a larger arc

Piano, strings, percussion, ambient layers, and dynamic transitions.

Studio questions

AI accompaniment, with musical control

The first release is being shaped around real performers, practical arrangement choices, and clear access for creators and students.

What can I upload?

Basic supports prompts, lyrics, and audio inspiration. Advanced Accompaniment is designed for a clean vocal, humming, or a single instrument playing a melody; the original performance remains part of the finished mix.

Do I have to know the chords or time signature?

No. Auto-detect proposes the tempo, meter, key, and compatible harmony. Musicians can edit and lock any value before generating an arrangement.

Can I enter an exact chord progression?

Yes. Chords can be entered by measure, including multiple changes inside a measure. Locked chords remain fixed while the accompaniment changes voicing, rhythm, instrumentation, and dynamics.

Will pay-per-song and subscriptions both be available?

Yes. Basic uses familiar credit-based monthly plans. Advanced Accompaniment can be purchased as one completed arrangement or through a higher-value monthly studio plan.

How does student access work?

Mike and approved students can receive sponsored access without checkout. Student grants can include a usage allowance and expiration date while generation costs remain visible to the administrator.
