If you're here, I recommend you check out MercuryMapper instead. :)

A Marvelously simple and scuffed editor, but this time it's cross-platform (tested on Windows, Linux, and macOS)! Currently mostly up-to-date with upstream v2.1.8.

For the most part, this is a port of the Windows Forms code, with "MVVM" in place to connect the dots into the old Windows Forms parts. It's horrible. There is some work to slowly start moving things to MVVM. If you are a developer, consider this caution tape in text form. Contributions/PRs are welcome and they will be reviewed (and merged) ASAP.

Non-Upstream Features

• Hardware-accelerated rendering and uncapped FPS (with a bunch of optimizations for performance)
• Built-in FLAC support
• Badly-implemented and very, very approximate hitsounds
• Dark mode, thanks to FluentAvalonia
• You can actually type in the number boxes (is this a feature?)
• Checks and prompts for a "End of Chart" note before saving
• Customizable note colors
• Hold Note baking (smooth out holds to be more accurate)
• Handles hi-speed gimmicks accurately
• Slide note arrows
• Cursor depth (change which beat notes are placed on)
• Optional cursor-following (cursor tracking mode) for note placing
• Highly WIP localization support - do not translate yet!

Cross Platform Code Warnings

This depends on ManagedBass. Since BASS doesn't have WASM support, the Web project is just the default Avalonia template. It might be as simple as adding another sound engine (IBakkaSoundEngine).

Neither the iOS nor Android projects function properly at this time. iOS support was worked on long ago, but is mostly nonfunctional today.
