MA Show Converter
Moves a grandMA2 show file down to an older software version. grandMA2 migrates shows upward on load and has no way back, so a show saved on a newer build will not open on a venue console running an older one.
The file never leaves your machine as anything but bytes in transit: nothing is stored, and the conversion happens in memory on the server and streams straight back.

Always load the result on a copy of the show and check the patch before a show day.
