I don´t know for sure if this is a bug or expected behaviour.
My preferred workflow in scaler 2 to is to bind some chords ,play them with my left hand and improvise a melody with my right (scale white keys).
However when perform mode is enabled, all held down notes(right hand) get stopped when the chord is changed.
This also results in sometimes cut of notes when the melody notes are played slightly before the chord notes, which is a bit of a improvisation killer
Maybe this can be fixed(if a bug).
