How can we help you?

Zalmaya is a desktop app for Windows and macOS. The exact system requirements will be given on the download page with the first release. The piano display uses your computer's graphics acceleration (WebGL).

Only from this website's download page. Do not install a version found elsewhere: it could have been modified.

No. All free features are available from the first launch, without an account. An account lets you back up your progress online and use Premium.

The installers are not yet signed with an Apple or Microsoft certificate, so a warning may appear on first launch. On Windows, click “More info”, then “Run anyway”. On macOS, open System Settings → Privacy & Security, then “Open Anyway”. Only do this for a file downloaded from the download page, whose SHA-256 fingerprint you can check.

New versions are published on the download page; their content is described in the changelog.

With your email address and a password of at least 10 characters, with an uppercase letter, a lowercase letter and a digit. Zalmaya sends you a 6-digit code by email to confirm your address. You can also sign in with Google.

Check your spam folder. The code is valid for one hour; you can request a new one after a minute. If nothing arrives, check the spelling of your address.

Choose “Forgot your password?” on the sign-in screen. You will receive a code by email that lets you choose a new password.

Yes. There is only one Zalmaya account: you sign in with the same credentials everywhere, and your Premium subscription follows you.

No, if the address is the same and has been confirmed: the Google sign-in is attached to your existing account.

From the Account page in the app: “Export my data” and “Delete my account”. For security, deletion requires a recent sign-in. If a subscription is running, cancel it first so you are no longer charged.

Connect your keyboard over USB, then open Settings › Controls in Zalmaya. Choose MIDI piano as the input source, select your device, then your keyboard size (25 to 88 keys).

Plug in the keyboard before launching Zalmaya, or restart the app after plugging it in. Close other music software that might be using it at the same time. On macOS, MIDI keyboard support is still being validated.

Notes outside the selected range are ignored. Check that the keyboard size in Settings › Controls matches your instrument; you can test each key live.

Adjust the Latency offset in Settings › Audio. Also check that the right Audio output is selected.

You can play with your computer keyboard: choose Keyboard as the input source and customise the keys in Settings › Controls. Lessons can also be played with the mouse.

In the Library, choose Import a MIDI and select a .mid or .midi file. The title is taken from the file name; you can then edit the details and add a cover.

Zalmaya does not provide a catalogue: you import your own files. Respect copyright; many classical works are in the public domain.

Zalmaya automatically splits the notes between left and right hand on import. Files that put each hand on a separate track give the best results.

With Premium, link a folder in Settings › Storage: new MIDI files placed there join your library, at startup or on demand. On macOS, this feature is still being validated.

Practice is for learning a piece: adjustable speed, wait-for-notes, virtual hands. Performance has you play the whole piece and scores it: score, combo, accuracy and rank.

Turn them on in Settings › Display (Virtual hands), along with finger numbers, their opacity and hint intensity. They appear in Practice mode when a fingering could be computed for the piece.

With Premium, use the A–B loop in the playback bar: set point A, then point B, and turn the loop on.

During a session, open the settings panel: Playfield view offers the immersive 3D view or the classic 2D view. Your choice is kept.

In Settings › Display, lower the Render quality cap, turn off Bloom glow or Impact particles, and set an FPS limit.

Premium comes as a monthly subscription, a yearly subscription and a one-time “lifetime” purchase. Prices (VAT included) and the full feature list are on the Premium page.

From the website's Premium page or from the Premium screen in the app, with your Zalmaya account. Payment takes place on the secure page of Stripe, our reseller, through its Link service. Zalmaya never sees your bank details.

On the Stripe payment page, click “Add promotion code” before confirming. The discount appears in the total immediately.

Premium activates as soon as Stripe confirms the payment to our servers, usually within a few seconds; the app and the confirmation page check automatically. If nothing changes, use “Restore my purchases” in My account › Subscription or in the app, signed in with the account that made the purchase.

With “Manage my subscription”, in My account › Subscription or in the app: it opens your Stripe customer area. After cancelling, Premium stays active until the end of the paid period.

Stripe, our reseller, emails you a receipt for each payment. You can also find the history in your Stripe customer area (“Manage my subscription”) and on link.com.

For a renewal, new attempts are made automatically and Premium stays active in the meantime. Update your payment method with “Manage my subscription”. For a first purchase, try again with another payment method: nothing is charged until the payment is accepted.

Two at a time. Beyond that, the app offers to free up an old computer's slot.

See the refund policy.

Instrument sounds are downloaded on first use: an Internet connection is needed at that moment. Then check the volume and the Audio output in Settings › Audio.

Your computer's clock seems to have been turned back. Set the correct date and time, then connect to the Internet so Zalmaya can verify your licence.

Premium works for up to 14 days offline. After that, connect to the Internet: Premium resumes as soon as it is verified. Free features remain available in the meantime.

Without an account, progress is saved only on your computer. Sign in and link your progress to your account to back it up and find it on another computer.
