Physical sample cards connect a printed or NFC code to one curated pack. A creator prepares the pack and previews the full customer journey before publishing. A fan opens the card, auditions the sounds, signs in, redeems once, and receives the pack in Meiji Sampler.

​
Get a creator into the studio

Creator Studio lives at /studio. Access comes from a creator profile, which an administrator creates.
1

Create the creator profile

In Admin → Creators → New creator, enter the owner email, display name, and slug. If that email has no Meiji Sampler account yet, one is created. Creating the profile sends nothing on its own.
2

Send the invite

Open the creator’s profile and choose Send invite. They receive an email with a sign-in link that opens Creator Studio directly. The link is good for seven days.
3

Resend if it goes astray

The profile shows when the last invite was sent. Resend invite issues a fresh link; any earlier link keeps working until it expires.
Creators can also sign in at any time from the Sign In page using their email—no invite needed once they know the account exists. Signing in takes each account where it can actually go: administrators land on the admin panel, creators land in Creator Studio, and everyone else lands on the home page.
Sign-in links are single use. Following one a second time will not sign anybody in, so request a new link rather than reusing an old email.

​
Manage a pack

Use Creator Studio for packs you own. Administrators use Admin → Packs to work across every creator. Both surfaces use the same Flowbite pack management workspace. Set your public name and optional public avatar image URL in Creator Studio → Profile. Your account email remains private and is used only for sign-in. Profile changes save automatically. When a pack’s Show creator attribution setting is enabled, customer pages and previews show this creator name.
1

Create a draft

Give the pack a unique lowercase slug, title, Description, and price label. Admins also select the creator who owns it. Use the rich text toolbar in Description for headings, emphasis, lists, quotes, code, or links. The editor saves Markdown.
2

Build the customer experience

Use Overview for catalog metadata. Use Experience for the redeem headline, Supporting copy, button label, creator attribution, accent color, and Redemption page theme. Minimalist is the silver-white default with a subtle frost-brushed texture; Meiji uses the dark technical Sampler look. The creator controls this choice—buyers cannot change it. Supporting copy uses the same Markdown editor. Titles, headlines, labels, and button text stay plain text. Valid Details and Experience changes save automatically and refresh the customer preview.
3

Add persisted assets

Use Assets to upload artwork (JPG, PNG, or WebP), ordered audio previews (MP3 or M4A), and ZIP downloads. Artwork is uploaded directly to the pack storefront image service and delivered as an optimized public card image. Use a 1.586:1 landscape credit-card ratio; 1600 × 1009 px under 2 MB is the recommended target, and artwork must be 10 MB or smaller. Existing artwork fills its card; use the × in its corner to remove it and restore Add artwork. Open Add preview or Add file, then select a file to upload it immediately. The Assets tab remains selected when the upload completes. If a preview title or download label is blank, the filename becomes its label. Preview and download tables keep playback, ordering, and labels scannable; open the horizontal three-dot menu on a row to rename, replace, remove, or select the primary download.
4

Prepare physical cards

Use Cards to generate serials, import a printer run, export the CSV manifest, reset a returned card, or void a compromised card. The Cards workspace has the same layout in Creator Studio and Admin, including card totals, two-column batch tools, pagination, and a horizontal three-dot action menu on every row. Reset and Void always open a confirmation dialog. Activity records management changes for later review.
5

Preview and publish

Use the Preview customer states sidebar beside Overview, Experience, or Assets and inspect Code entry, Available signed out, Available signed in, Redeemed by this account, Redeemed by another account, Voided, and Invalid. Code entry, both Redeemed states, and Voided retain the same pack card artwork, creator, and title as the customer card view. These pages are clearly marked read-only and cannot redeem, download, write data, or emit analytics. The Available previews render Supporting copy with the same safe Markdown presentation as the live customer page. Complete all five Publish readiness steps, then choose Pack actions → Publish.
The five Publish readiness steps are Pack details, Customer experience, Artwork, Audio preview, and Primary download. Select Complete on an unfinished step to open and focus its exact field. Publishing still requires a description, redeem headline, redeem copy, artwork, at least one audio preview, and exactly one primary ZIP download.The pack toolbar presents Publish as the primary action until a pack is live. Controls that would leave the pack in its current lifecycle state are not shown.Use Cards in the Creator Studio sidebar to review every redemption card across your packs. Each row shows its issuing pack, status, redemption date, and the same Reset and Void controls available from that pack’s own Cards workspace.
Customer pages sanitize formatted copy before rendering it. Raw HTML, scripts, embedded images, event handlers, and unsafe links are not accepted as formatting. Existing plain text remains valid and needs no conversion. Customer actions—including recovery navigation after an invalid code or rate limit—render as full-width buttons. In read-only previews, the same actions remain visibly disabled and cannot navigate.

​
Asset and lifecycle safety

  • Replacing an asset confirms the new object before changing the saved reference.
  • Removed and replaced objects enter a durable storage cleanup queue. Administrators can use Retry storage cleanup when an upstream delete failed.
  • A live pack cannot lose its last required customer asset.
  • Archive a pack to take it out of circulation while retaining customer and audit history.
  • Permanent deletion is limited to an unused draft with no cards, entitlements, or customer history.

​
Redeem your card

  1. Tap the NFC card with your phone, open its printed URL, or visit sampler.meiji.industries/redeem.
  2. Preview the sounds and confirm the pack details. The physical-card view shows the uploaded artwork when available, a designed fallback otherwise, preview count, Direct Download delivery, and card value. The seller-selected theme stays visually consistent on every device: Minimalist remains cool silver-white with a frost-brushed finish and Meiji remains dark and technical. The card responds gently to pointer movement on desktop and scrolling on touch devices, while respecting reduced-motion preferences.
  3. Enter your email and open the magic link on the same device.
  4. Tap the creator-defined redeem button. The pack is attached to your account.
  5. Download the files from the success page or open Meiji Sampler.
After redemption, the success page links to more live packs from the same creator and the broader catalog. Public pack pages expose product copy and preview audio only; downloads, serials, storage keys, card batches, and drafts remain private.

​
Get the pack in Meiji Sampler

  1. Open Meiji Sampler and sign in with the same email used for redemption.
  2. When Your pack is ready appears, press [ENTER] to open Your Packs. You can also find the pack tagged [CARD] at the top of the pack browser under Settings → Sources → Pack browser.
  3. Select and download the pack. It installs like a factory pack.

​
Troubleshooting

  • Publish is blocked: select Complete beside each unfinished Publish readiness step and fill the field it opens.
  • Uploads are disabled: storage is not configured on the server. Existing pack data remains editable.
  • An asset cannot be removed: add a replacement first, or archive the live pack.
  • Permanent deletion is blocked: archive the pack. Cards or customer history intentionally prevent deletion.
  • Already redeemed on another account: each card unlocks one account. A second-hand buyer should ask the seller to reset it.
  • This code doesn’t look right: codes ignore dashes and case. Check the printed code, then contact the seller if it still fails.
  • The pack does not show in the app: confirm the app uses the redemption email under Settings → General → Account.
