This means less worry about hitting every note perfectly in real-time and more freedom to focus on expression and performance.
What I appreciate even more is the inclusion of three distinct vocal effect modes labeled as WARM, BRIGHT, and NORMAL, each offering different EQ adjustments. This gives me the flexibility to tailor my vocal tone depending on the song or setting.
