Hiya Ze,
The Create and Correct are great units for doing what you have suggested.
There are several new features with the new Create and Correct XT. Notably the Correct XT features an Anti-Feedback feature which is fantastic for using live. With the Create XT there are several new features including the below:
• Front-of-house-quality reverb algorithm from VoiceLive 2
• HardTune for live, auto-tuned vocal effects
• The Tone button that polishes and smoothes vocals with adaptive Live Engineer Effects
• Dedicated effect block on/off buttons for easy preset customizing
• Selectable Tweak parameters give you access to the important elements in the current sound
• USB connection for easy software updates, tips, and preset backup using the included VoiceSupport application
• Easy selection of HardTune scale & key from a standing position
• Pedal input that accepts TC Helicon three button footswitch for more creative performances
Hope this helps! For more info on these products it may be a good idea to check out the manuals which are available as a free download from: www.tc-helicon.com/manuals or even doing a product search on YouTube.
Best wishes,
Joey
