If you're using MIDI tracks, you can make notes seem to have a fermata effect by lengthening the notes in the PianoRoll. This will not work with RealTracks though because those are auto-generated only.

There are holds that you can place on chords in the Chords view, however, this does not adjust the tempo. Also, the chord will hold until a new chord is written, so it won't sound like a fermata on the first chord with another chord right after it.

Since the RealTracks are made from audio, it may or may not be feasible to make them lay fermatas on certain notes. But we will make a Wishlist report to development for making a fermata feature and see if they think it's possible.

Best,
Chantelle
