The V71 supports 32 channel streaming audio and MIDI to/from the computer via its USB port. For this functionality, the V71 drivers must installed in your computer, and the USB Driver Mode in the V71 must be set to "VENDOR" from its default - (which is "GENERIC"). Here are Steps and information for proper setup:
First, download and install the appropriate USB drivers.
For Mac OS and Windows, drivers can be found on the V71 downloads page here: https://www.roland.com/global/products/v71/downloads/
(Installation instructions are included within the download.)
*** Take note of the Mac OS troubleshooting information in the Readme_xx.htm within the download folder, as Mac OS versions may block the installation of drivers in the background. You may need to "approve" that the drivers can be installed in the Security and Privacy section in your Mac.
For Windows 10/11, drivers will be downloaded and installed automatically once you have changed the V71's USB Driver Mode to VENDOR, connect the V71 via USB to your PC, and have an internet connection established. (Note - there is no physical driver file to download for Windows 10/11).
Here's how to set the V71's USB Mode to "VENDOR:"
- Press the SETUP button.
- Cursor to highlight "USB AUDIO," and then press ENTER.
- Turn the main dial clockwise to choose "VENDOR".
- A USB Driver message prompts in the V71's display stating that the new modified settings will become effective after restarting the V71. Press ENTER to select "OK" for this message. - Use the power switch on the V71 to turn off its power, and then power back on again.
- After installing the drivers and switching the V71's USB Mode to VENDOR, connect the USB C port on the side panel to a USB port on your computer, then select the V71 as an audio and/or MIDI device within your software.
