Critic Reviews

Musikmesse 08: TC Helicon VoiceTone Harmony M pedal | MusicRadar

musicradar.com

TC Helicon's VoiceTone Harmony-M pedal impresses with its ability to produce two simultaneous vocal tracks, enhancing live performances for keyboard players. Its MIDI integration enables seamless harmony control without affecting keyboard signals, while adaptive EQ and compression ensure polished vocal output. The pedal's intuitive controls and multiple presets offer versatility during performances. However, its niche focus on keyboardists may limit appeal for broader audiences, and potential buyers should note the reliance on MIDI for optimal functionality. Overall, it's a solid choice for keyboardists seeking to enrich their live sound with easy-to-use vocal harmonies.

Great Manual Harmonizer

The predecessor to later TC pedals with "Notes Mode" like the Voicelive Touch, Voicelive Touch 2, Voicelive 3, Voicelive 3 Extreme, Perform-VK, and Perform-VE, the Voicetone Harmony-M is a great harmonizer pedal that lets you play the harmonies you want via MIDI in a mode this pedal calls "Manual Mode".

I used it for harmonizing myself on both horns and vocals live and it worked well. That said, I upgraded to a Perform-VE and that's in a whole different league. It's been long discontinued and there usually aren't any for sale so they're hard to track down. If you can find one for cheap get it, otherwise I'd just go with the Perform-VK (or VE if you can afford it).
