Cloud Library

The Cloud Library in The Ultimate Piano stores MIDI files, audio, MusicXML and PDF scores and lead sheets online. Sort them into folders of your own and open the same file on any computer you sign in on — annotations and page timings included. There is also a public collection you can search and contribute to.

It's the same Library button everywhere you load or save a file, so your whole practice library lives in one place instead of scattered across downloads folders on different computers.

How to Open the Cloud Library

Wherever you can load a file, you'll see a Library button:

• In the MIDI Player and Audio Player
• In the Sheet Music Player — for both MusicXML and PDF scores
• In the Leadsheet Editor

Click Library and a dialog opens with two areas: Cloud (your own files plus the public collection) and Local (load straight from your computer). The Cloud area has two tabs: My Cloud for your own files, and Public Cloud to browse what others have shared.

Save Music Online

Open My Cloud, expand Upload new file, and pick a file. The Library fills in the details for you:

• The title comes from the file name, so you don't have to type it.
• For MIDI, MusicXML, and lead sheets, the tempo, time signature, and key are read straight out of the file.

Anything the app fills in automatically, you can still change — and it never overwrites something you typed yourself. Add a genre, set a difficulty, or pick a key from the Circle of Fifths if your file doesn't carry one. Choose a folder, decide whether the item is Private or Public, and click Save to Cloud.

A file that's too large or in the wrong format is rejected before anything uploads, with a clear message — so you never wait on an upload that the server would refuse.

Each account has 1 GB of cloud storage. Individual files can be up to 10 MB (MIDI, lead sheets) or 50 MB (audio, PDF, MusicXML).

Organize With Folders

Everything lives under a reserved top-level folder called Home — your anchor, always there, and it can't be renamed or deleted by accident. Under it you can build whatever structure fits how you practice:

• Create folders — right-click a folder in the sidebar tree and choose New subfolder. Nest them as deep as you like (e.g. Exercises/Czerny).
• Move a piece — use the Move button on any item and type or pick the destination folder. The view jumps to that folder so you can see it landed.
• Rename a folder — right-click and Rename. Every piece inside moves with it; nothing gets lost.
• Delete an empty folder — right-click and Delete folder. The folder disappears from the tree, and your pieces are never harmed.

Set up a folder per student, a setlist folder for Saturday's gig, or a folder for each composer you're working through.

Find Any Piece in Your Music Library

Click a folder to filter the list to just that folder. Every item shows the details that help you recognize it at a glance — key, tempo, genre, and its folder — so you can pick the right piece before you open it, even when you have dozens stored.

Open It Again — Wherever You Sign In

Save an arrangement on your laptop at home, sign in on the studio computer the next morning, and open it from My Cloud — no USB stick, no email-to-self. Click Open on any item and the Library loads the exact same file you saved, byte for byte, straight back into the editor or player. What you put in is what you get back.

Discover & Share in the Public Collection

Switch to Public Cloud to browse pieces other players have shared:

• Search by keyword and filter by genre, then sort the results in 3 modes — newest, top rated, or most popular.
• Each result shows its rating, favorites, and view count so you can judge it at a glance.
• Rate a piece with stars and favorite it to find it again later.
• Open a public piece to load it straight into the player and play along.

Want your own work out there? Flip any item from Private to Public (the 🌍 button) and it becomes searchable in the public collection. Switch it back to private any time and it leaves the collection again.

Which Files Can I Store?

Those are 4 types of file, and each keeps its own library — the Audio Player alone accepts up to 8 audio formats (MP3, WAV, OGG, FLAC, M4A, AAC, AIFF, MP4) — so your MIDI files and your PDFs never get mixed together.

Related: Load and practise files in the MIDI Player, Audio Player, and Sheet Music Player. Build your own charts in the Leadsheet Editor and save them to the Library.

Frequently Asked Questions

What files can I save to the Cloud Library?

MIDI files, audio files (MP3, WAV, OGG, FLAC, M4A, AAC, AIFF, MP4), MusicXML and PDF scores, and lead sheets. Each file type has its own library, opened from the Library button in the matching player or editor.

Will I get back exactly the file I saved?

Yes. Opening an item loads the same file you uploaded, byte for byte, back into the editor or player. The details you add (key, tempo, genre) are for finding and recognizing the piece — they never change the file itself.

Can I open my files on another computer?

Yes. Your library lives in the cloud, so you save on one device and open on another — just sign in with the same account. There's no USB stick or manual transfer.

How do folders work?

Everything lives under a reserved Home folder. You create subfolders from the sidebar tree (right-click → New subfolder), move items between them, and rename or delete folders — renaming a folder carries every piece inside it along, and deleting an empty folder never touches your files.

Can I share a piece with other players?

Yes. Set an item to Public and it becomes searchable in the Public Cloud, where others can open, rate, and favorite it. Switch it back to Private any time to remove it from the collection again.
