In Waves Tune (not realtime), clicking the keyboard plays a pitch. This helps the user work out which notes to approve or block. Even if you don’t know the scale, you can click around to figure out how to set up what notes are allowed manually.
However, in Waves Tune Realtime – clicking the keyboard does NOT play a pitch.
It would be helpful to have the clickable keyboard pitch in Waves Tune Realtime, and it would also make the two tools more consistent with one another.
