The MVR menu provides a way to exchange and manage MVR files over a network connection instead of using a USB drive. For more information about MVR files in general, see [My Virtual Rig (MVR)](/grandma3/2-4/patch_mvr/).

The MVR-xchange is specified in the DIN SPEC 15801:2023-12. For more information, see the external link <https://www.beuth.de/en/technical-rule/din-spec-15801/373968511>.

The idea behind the MVR menu is to send MVR files from a station to a defined network and share them with other stations. For more information about the appropriate keyword, see[ SendMVR Keyword](/grandma3/2-4/keyword_sendmvr/).

To open the MVR menu:

1. Press Menu. The menu opens.
2. Tap In & Out. 
3. Tap MVR. The MVR menu opens.

The three elements on top of the menu are described as follows:

- Group: The standard group name is **Default**. The group name can be edited. Stations with identical group names share the same exchange group.
- Interface: Defines the network interface.
