Description

uDMX is a design of a tiny, USB-powered DMX interface. QLC+ supports these, and the drivers are in the Linux kernel. The design is open and it's easy to buy cheap devices based on it (even if they don't come with a copy of the GNU GPL license as they should...).

As I've gotten one myself as a "baby's first DMX interface" I'd love to be able to drive it directly from Ossia Score, without needing to use QLC+ as a middle-man.
