Our verdict on grandMA3 onPC

grandMA3 onPC is MA Lighting’s computer-based grandMA3 lighting-control software for Windows and macOS. It is aimed at lighting professionals preparing or operating shows, particularly existing grandMA3 users, smaller productions and people working with smaller budgets. The free desktop software covers show preparation, fixture types and patch data, with a 3D Viewer for examining show content. Its design value is practical: preview within a lighting-control workflow rather than manage every stage of lighting design documentation in one place.

The 3D Viewer can show previewed or live output, and fixture types can be imported from grandMA3, converted grandMA2 and GDTF libraries. A fixture type editor supports creating and modifying fixture types. These capabilities make onPC relevant when the priority is checking fixtures and show output before or during control work. It is not positioned as a full plot or paperwork tool, so teams that need those deliverables should consider a dedicated design application alongside it.

The software is free to download, but output capability depends on the connected system: DMX output requires compatible grandMA3 onPC solutions hardware. MA-Net3, MA-Net2, sACN and Art-Net are supported via onPC xPort Nodes, while RDM is also listed among its integrations. That makes protocol and hardware fit important to assess before planning a show workflow. Choose onPC for no-cost grandMA3 preparation and visualization on Windows or macOS; look elsewhere if your central need is standalone plotting or paperwork rather than lighting control.
