The Piano Roll would benefit substantially if the audio preview triggered when a user selects / highlights a note or group of notes.
This is useful for drafting chord progressions as you can surgically preview pieces of chord rapidly to hone in on the notes you actually want.
Audio preview of notes requires an additional click, which is not ideal nor necessary.
It’s a small improvement in a very common workflow.
Right now you can have an audio preview of a note or a group of notes (played as a chord) by clicking (single note) or shift clicking (group of notes). Also by dragging the note or groups of notes to a different position.
