Roland VT-4 Voice Transformer

The description of this item has been automatically translated. If you have any questions, please feel free to contact us.


The VT-4 is an effects processor for the central instrument in all of us - the human voice. Like our voice, the VT-4 is intuitive to use and extremely effective at the same time. Whether you're a solo EDM artist, working as a DJ, or singing in a band, the VT-4 lets you shape and shape your vocal sound in unique ways, from subtle augmentation to radical transformations. It's incredibly easy to use - no more diving into nested menus to get the desired results. This way, breathtaking vocal effects such as harmonizers, vocoders, pitch changing, Mickey mousing and many more are just a button, slider or controller away. Thanks to the compact housing and a battery life of five hours, you can use the VT-4 anywhere.
