I didn't know about DMXIS and tried to look it up, and it seems that there is a software and a hardware component (the latter not being produced anymore), see here:

I don't know about the software, but as for a DIY hardware solution, you can just connect a USB-DMX interface (like the Enttec DMX USB Pro) and a USB-MIDI device to a laptop and "just" have to code something to translate MIDI input to DMX output. Or use an Arduino, an RS-485 module and a few other components, that's what I once did.

Ah yes I should've been more specific - the DMXIS box from Enttec is a small piece of hardware which takes MIDI input and has an output port for DMX fixtures. Accompanied by a software to create mappings from one to the other. Would be a fun project to design and code this but I was wondering if there is anything similar out there already :)
