The workflow difference
Waves lists transmission to Waves Tune Real-Time, Waves Tune, OVox and Waves Harmony, with version requirements. That integration is different from setting the DAW's project tempo or sending to Auto-Tune. The receiving tool is the useful comparison, not the word detection on the box.
If the vocal chain already uses Waves Harmony or Tune, check the Transmit workflow. If references arrive from several apps and the project needs a tempo as well as a key, check SESSION™ Key's input modes and the destination compatibility list.
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
Verify both the detector and receiving Waves plugins meet the listed version requirements. Audition the selected scale against the vocal before committing tuning.
