Hardware vocal processing was once the preserve of live performers. But now the technology is much more advanced, not to mention affordable, and it has become much more widely available. Roland’s latest offering in this field is the VT-4 Voice Transformer, a powerful new effects processor for manipulating the human voice.
Compact and easy to use, the VT-4 allows the user to connect a microphone and quickly craft unique vocal sounds with performance-oriented controls. It puts a wealth of modern and retro vocal effects at the user’s fingertips, eliminating the need to employ a complicated setup with a computer and plug-ins.
