Why this pattern works

Align the current pattern with the larger arrangement so users can move between detail and sequence.

Design notes

Surface: Music sequencer
Navigation: Pattern and instrument choices remain adjacent to the grid they modify.
Layout: The note grid sits above numbered pattern rows, with transport and song settings in a right column.
Density: The working preview takes most of the space, with compact controls grouped around it.
Color: Dark editing surfaces with contrasting colored pattern cells and pale transport controls.
Type: Use repeated cells and stable row alignment to make timing and pattern structure legible.
Pattern: Align the current pattern with the larger arrangement so users can move between detail and sequence.
States: The initial public song workspace; no song was published or audio started.
Don't: Adapt the interaction pattern to your own product. Do not copy brand assets, sample identities, proprietary text, or assume unseen states. Specify keyboard behavior, loading, empty, error, and narrow-screen layouts for your implementation.

## Objective
Adapt the interaction and layout patterns below to my project. Use my own content and identity. Do not reproduce logos, proprietary copy, or brand assets.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Reusable components and semantic HTML express the interface. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
