Voice transformer, voice changer, can create a female voice. It's old equipment, so it shows signs of use, and no option cables are included. I'm selling it because I bought an E-4. I think the sound is better than the E-4. You can use scat, which the VT-4 didn't have. It's better to research before you buy, but Roland has stopped updating the drivers, so it can't be used as an audio interface except on Windows 10. If you are streaming, please input from the analog output to the computer. - Model: VT-3 - Brand: Roland - Function: Voice Transformer - Controls: Pitch, Formant, Vocoder, Synth, Lead, Bass, Mix Balance, Reverb - Connectors: XLR, Line Output - Special Features: Auto Pitch, Direct, Scatter function Thank you for viewing.
