SESSION™ Key in this workflow
- 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.
