The green octave: Low string chords (C2-B2) Major & Minor chords triggered by velocity The blue octave: Low, Mid, High chords played together (C1-B1) Major & Minor chords triggered by velocity Dynamics: The mod wheel gives you further possibilities to adjust the dynamics and enables you to mix sustain and tremolo chords.
BARRE CHORDS FOR THE GUITAR by DON COMANDA FOREWORD Following are over 1,700 chords. Barre chords are shown throughout except in cases where a Barre chord would give too “thick” a sound. A quick reference section is included showing major, minor, and dominant seventh chords. Similarly fingered chords appear with different names.
