A playable part inside a chart, such as lead guitar, rhythm guitar, bass, drums, keys, or vocals. The arrangement controls what notes appear, what tuning is expected, and what scoring compares against.
ASIO
A Windows audio driver path often used by low-latency audio interfaces. If a device appears as both ASIO and Windows Audio, choose the path that matches your setup.
Audio Interface
External hardware that connects instruments or microphones to the computer. Interfaces often provide cleaner input and lower latency than a built-in microphone.

Build
A specific version or packaged copy of FeedBack. When reporting issues, include the build you used.
