This article covers the download details and an overview of SLB Key.
What Is Salonebeats “SLB Key”?
SLB Key is a key and BPM analyzer plugin that analyzes the audio you are playing in real time, simply by inserting it on a track. It displays the detected key, the BPM, and compatible keys on the Camelot wheel. There is no need to export files or drag and drop anything, and it is designed for producers who work heavily with loops and samples, such as melodies, chords, pads, and full beats. It is currently distributed as a free beta, and version 1.3.0 added Audio Unit (AU) support, so it can now be used in Logic Pro and GarageBand as well.
Key Features
- Runs key detection in real time (shows the Camelot number and a confidence score)
- Shows the relative key directly under the result (for Am, C major is also displayed)
- Provides two alternative candidates to choose from when the result does not feel right
- BPM display with half-tempo and double-tempo support; shows “No rhythm detected” when the rhythm is unclear, such as with pad sounds
- Shows compatible keys on the wheel (relative, adjacent, and parallel keys)
- Switch between key names and Camelot numbers (Am / 8A) and choose sharp or flat notation
- The audio signal passes through unchanged, and nothing is uploaded externally
