The Harmony-G XT is the successor to TC-Helicon’s Harmony-G vocal effect and takes some features from the more upmarket VoiceLive 2. This is a vocal effects pedal that is designed for singers who are also keyboard players. It allows you to add vocal harmonies to your voice, depending on what chords you play with the keyboard, and what mode/preset you currently have selected. It has 20 total preset slots (10 banks, 2 a/b presets per bank), and master tone, humanize, fx, and harmony controls. Features 1/4″ TRS mic level I/O, as well as input for an optional footswitch so the VoiceTone can be placed on the keyboard for easier access. With intelligent arrangement of 2-harmony voices based on MIDI and voice input, Harmony-M is an essential tool for singing keyboardists.
According to several user reviews of TC Helicon VoiceTone Harmony-M, some dedicated footswitch for harmony switching; two different patches instantly footswitchable; harmonies generated from guitar; very durable. Also, some users have complained it for the setting the key manually requires a lot of footswitching activity; the input is an unbalanced.
