A simple way into your next session.

CEDRA keeps your own guitar PDFs and recorded practice together. Practice on a laptop or desktop using Chrome or Safari.

Three steps

Start with one PDF.

  1. Upload your first PDF

    Open Import PDFs, choose Choose PDFs, then Import Selected. Check the file count and PDF size limits shown before selecting files. The results distinguish imported, duplicate and failed files; successful imports stay in your library.

  2. Open Reader and practice

    Select Open Reader for an imported PDF. Titles, tags, Spotify and building a practice set are optional. You can use a valid PDF while leaving suggested metadata corrections for later.

  3. Save practice and revisit your music

    Choose Finish Session to review your practice, then Save Session. Return to Profile for your recorded practice, or Library to open a piece again.

Know what has been saved.

Elapsed time
The session timer tracks time while running and pauses when you leave the app. Choose Resume when you return. Time becomes recorded practice when you save the session.
Logged plays
Plays are the counts you explicitly record. A time-only session can be saved without adding a play.
Reader notes
Editing a note creates a draft on this browser. Use Save Notes and check its confirmation. Drafts are not the same as a saved practice session.
Saved practice
Finish Session opens a review; Save Session records it for your account. Profile reflects saved results; it does not measure every visit or every time a PDF is open.

If a save fails, keep the session or note draft and retry. Avoid clearing browser storage while recovering a draft. If the library cannot load, use Retry before assuming your music is gone. Contact Leo if a problem persists.

Access and account recovery.

Requesting access is the first step

The first cohort is free and founder-approved. Request an invite to join Leo’s review list. A request does not create an account or guarantee an invitation. If approved, use the separate invitation email’s link to create your account, then sign in.

If an invitation or reset does not arrive

Check spam and confirm the email address you used. Contact Leo from that address for help with a missing, expired or used invitation. On the login page, choose Forgot password? for password recovery. If you cannot complete the reset, contact Leo rather than creating another account.

If your music will not load

Confirm you are signed into the right account. Retry the request, and sign in again if your session has expired. Include the error text when contacting Leo. Keep your original PDFs; do not use Start Clean Library to troubleshoot a loading problem.

Keep your originals. Understand your exports.

In Profile → Library exports, Export library data includes song metadata, notes, tags, play totals, recent song logs and Spotify links. It does not include complete session history or PDF files.

Use Choose PDFs and Download Selected to download stored PDFs separately. The app shows selection and download limits. Keep your original PDFs alongside exported data.

Use Profile → Your practice data → Export all practice data for all saved sessions, logs and retained song notes. Self-service account restore is unavailable; these exports do not restore an account automatically.

Removing music or deleting an account

Removing music and Start Clean Library permanently remove the PDFs from your active Library while keeping saved practice and song notes. Find them under Profile → Removed scores. Reimport the exact original PDF to reconnect an identified score. If the original could not be uniquely identified, reimport may create a separate score; the saved history stays in Profile. Full account deletion also deletes practice data.

For an account deletion request, use the contact form with your account email. State that you want the account and its stored data deleted. Leo handles the request personally and can confirm its scope before removal.

What this beta supports.
