TC HELICON Harmonizer VOICETONE HARMONY-G XT This unit has a pitch correction function with key selection, but it was very subtle, for better or worse. You can't expect an Auto-Tune-like effect, and I think it's equipment for advanced singers. I couldn't handle it... If your pitch is stable, I think it's easy to use. There are many types of harmonizers, and you can also apply spatial effects, de-essers, and compression. ▼Product Description Latest "NaturalPlay" harmony algorithm controlled by guitar playing High-quality reverb & reverb styles inherited from VoiceLive 2, 4 types of doubling FX that can obtain overdub effects (also applicable to harmony voices) FX presets that support a wide range of music styles, software update/preset backup application "Voice Support" via USB connection Added an adaptive gate function to the "Tone" button, which automatically optimizes the vocal tone, to suppress microphone input when not singing Tone switch that applies appropriate EQ/compression/de-esser to live vocals with a single button, 18 combinations of reverb, delay, and μMod FX that can be applied to both vocal and guitar inputs
