The workflow difference
The KeyFinder project describes an open-source analyzer without a media player or library-management system. Its website points Windows and Linux users to Mixxx, which uses the KeyFinder algorithm. The site distinguishes current App Store information from older downloadable versions.
For a collection of existing files, verify which KeyFinder release supports the computer and how results are saved. For a reference that is already playing, SESSION™ Key reads the Mac output without first obtaining the source file.
SESSION™ Key at a glance
- Price
- $49 once
- Requirements
- macOS 14.4 or later on Apple silicon. One license covers up to three Macs.
- Input and setup
- Read system audio, use the microphone, or drop an audio or MIDI file on the menu bar. Live analysis follows the passage playing; a file gives the analyzer a different span of material.
- Working with it
- Optional Beta sends connect the reading to supported DAWs and Auto-Tune. The fields and setup vary by destination. Check the integration guide before purchasing for a particular send.
- Before the session
- The outline marks a locked reading; green and amber communicate confidence separately. A locked reading can still be uncertain. Listen, check the musical context, and use the half-time or double-time control when the pulse needs it.
Before the first session
Do not assume an old free download is the current supported build. Confirm its operating-system compatibility and the distribution's license before installing.
