Description
The Roland VT-4 is a compact real-time vocal processor that transforms your voice from subtle pitch correction to dramatic effects like vocoding, harmonizing, hard tuning, and formant shifting. Dedicated faders and buttons allow smooth control over pitch, formant, balance, and reverb, with one-touch variations for lo-fi effects, multi-part harmonies, and delays. Up to eight scenes can be stored and recalled instantly for live or studio use. MIDI integration lets you control harmony and vocoder effects in real time for dynamic, layered vocals. Inputs include XLR/¼” with phantom power, stereo TRS outputs, and USB audio with loopback recording. Powered via USB or batteries, the VT-4 is ideal for singers, DJs, streamers, and podcasters crafting unique vocal sounds anywhere.


Vocal Transformation
The VT-4 lets you modify pitch and formant in real time, creating subtle enhancements or dramatic voice changes.
