Arrangements

An arrangement is a reusable musical configuration, not a song generator. It sets harmony and companion behavior while preserving your tonic, tempo, transport, devices, routing, sound, master level, mute/solo state, and hosted plug-ins.

Apply an arrangement

1. Choose a preset.
2. Read Result and Play it like.
3. Check whether transport is required.
4. Press Apply.
5. Play the recommended input type and leave the requested space for delayed parts to finish.

Only fully implemented built-ins appear in production menus. Research drafts remain in the internal catalog but are hidden until operational.

Save a custom arrangement

Use Save As to capture the current arrangement controls with your own name, result, playing prompt, and references. Custom presets appear beside operational built-ins and can be edited or removed without changing the built-in catalog.

Judge the behavior, not the label

Each preset documents what it approximates and what it deliberately does not model. Your articulation, phrase, register, silence, and sound choice remain part of the arrangement.
