It’s a bit too cumbersome to turn the parameter on/off (at least without a key command)
being able to hold ‘alt’ and use the playback tool and have that band parameter engage, and then release to disengage would be nice workflow.
also, expanding on this band playback mode by having a harmonics mode parameter with it’s own modifier - alt+shift maybe.
Thank you very much for adding this feature, so useful. much easier than making selections and doing selection playback (as selections interrupt the undo/redo history)
side note, could also have a ‘Loop’ parameter, that loops playback from the mouse cursor position to the end of the event, so the user can move their mouse around while click-holding playback and find problems both across time and frequency while having that continuous loop playback.
