d&b Adds MVR Exchange to ArrayCalc Beta
The feature lets users import and export venue and loudspeaker data using the open MVR standard.
Updated on Nov. 5, 2026 in Music — General
d&b audiotechnik has introduced MVR Exchange in the latest ArrayCalc beta version. The feature enables users to import, export, and update venue and loudspeaker system data using the open MVR standard.
Why it matters
MVR Exchange provides a manufacturer-neutral way of exchanging project information across disciplines and reduces the need for manual model recreation and data transfer between teams.
The announcement is a product feature disclosure rather than a measured dataset, and it does not include quantitative metrics. Details on how widely the MVR standard is adopted across the industry were not included in the source information.
The players
d&b audiotechnik
d&b audiotechnik is a German manufacturer of professional loudspeaker and sound reinforcement systems known for its line array and touring sound products.
Vectorworks
Vectorworks is a software company that makes CAD and design software for architecture, entertainment, and landscape design, and it was one of the developers of the MVR standard.
MA Lighting International
MA Lighting International is a German company that develops lighting control consoles and software for the entertainment industry, and it was one of the developers of the MVR standard.
ROBE lighting
ROBE lighting is a Czech manufacturer of moving-head fixtures and entertainment lighting products, and it was one of the developers of the MVR standard.
The details
MVR Exchange allows users to import venue models from external applications into ArrayCalc and export sound system designs back into the wider production workflow. The MVR standard includes venue geometry, staging, lighting, and loudspeaker system data, and exported loudspeaker data can be visualised and coordinated within CAD environments.
Timeline
The feature is available as part of the latest ArrayCalc beta version, and the MVR Exchange article was published on 5 November 2026.
Industry Dynamics
The MVR standard was developed by Vectorworks, MA Lighting International, and ROBE lighting as an open DIN standard used across CAD, lighting, and visualisation platforms. MVR Exchange extends that interoperability into professional live sound design workflows, which previously relied largely on proprietary file formats.
The feature affects sound engineers and production designers who use ArrayCalc, allowing them to move venue and loudspeaker designs between software environments without recreating models manually. Audiences are not directly affected, as the announcement concerns production workflow tools rather than ticketing, streaming, or event availability.
The takeaway
Production teams can reduce repeated modelling work by exchanging venue and loudspeaker data through a shared open standard. The approach offers a practical way to coordinate sound design with lighting and CAD planning across a single project.
