System requirements
A recommended baseline. It runs on less, but this keeps everything smooth.
- Operating system
- macOS 11 Big Sur or later, Windows 10 and 11, or 64-bit Linux (Debian, Fedora and friends).
- A MIDI keyboard
- Any MIDI piano or controller, connected over USB or Bluetooth. Without one there are no notes to read.
- Processor
- Any 64-bit dual-core CPU from roughly the last decade. No dedicated graphics card needed.
- Memory & storage
- 4 GB of RAM and around 150 MB of free disk. It's a small native app, not a heavy runtime.
- Connection
- One online activation, then fully offline. Everything stays in a local database on your machine.
Your timing is stamped in a native layer the instant each note arrives, so a modest machine still scores you honestly. You don't need a fast CPU for an accurate grade, only for smooth visuals.
