Does the VT-4 require a computer to work?
No, the VT-4 is a standalone hardware unit. It processes your microphone input internally and outputs the effected sound directly. A computer is not required for its core operation, though it can connect via USB for use as an audio interface.
What type of microphone input does it have?
It has a balanced XLR microphone input on the rear panel, suitable for dynamic or condenser microphones (phantom power is not provided). It also has a front-panel 1/4-inch jack input for an instrument or line-level source.
Can I use it with a MIDI keyboard?
Yes, the VT-4 has a 5-pin DIN MIDI input. Connecting a MIDI keyboard allows you to control the pitch of the Auto-Pitch, harmony, and vocoder effects in real time, enabling you to play chords for harmonies or melodies for vocoded parts.
What is included in the box?
The unit typically comes with the VT-4 processor itself, four AA batteries for portable use, a USB cable, and a quick start guide. A microphone is not included.
How do you save effect settings?
You can save your complete effect chain and settings by holding down one of the four numbered preset buttons for a few seconds. The current setup is then stored to that button for instant recall later.
What is the warranty period?
Roland products generally come with a standard manufacturer's warranty, typically for one or two years. It is advisable to register the product and check the documentation provided with your specific unit for confirmation.
Can I use multiple effects at the same time?
Yes, the VT-4 allows you to chain multiple effects together. For example, you can apply pitch correction, then add a vocoder effect, and finish with delay or reverb, all simultaneously.
