Roland VT-4 Operation confirmed. I only tested it once here. The main unit, cable, box, and instruction manual are all included. Please see the photos for the condition. -- Freely change pitch/formant, easily control pitch correction. A popular model of voice transformer. Roland's voice transformer can process pitch and formant in real-time with high sound quality, and is used by many artists as a device that can easily reproduce extreme vocal sounds live. Among them, we have received many voices from artists who use it in live performances and on stage. The new VT-4, while maintaining the original concept, further refines its performance as a dedicated machine, making it easier, faster, and more understandable, and is a voice transformer that meets the expectations of artists.
