The TC Helicon Voicelive Rack provides hundreds of presets for vocal effects in a rack. With 238 factory presets and 400 user defined presets, as well as a touch interface and USB output for updates, the Voicelive Rack is sometimes considered a "personal vocal assistant" in a rack. Effects include reverb, tap delay, modulation effects, global effects and more, all of which can be used simultaneously or alone.
