ChordScope vs iChanges

ChordScope visualizes harmony in real time from MIDI input. Connect a MIDI keyboard or controller and play. ChordScope detects the chord you’re playing and highlights the corresponding notes on a one-octave piano keyboard.  Notes that belong to the chord’s scale are shown clearly, making harmonic relationships easy to understand at a glance. Ideal for musicians, composers, and learners, ChordScope provides immediate visual feedback to help you explore chords and progressions as you play.
