This is more of a lighting controller while QLab is a show controller. These are typically viewed as different layers of the stack: a show control system controls the light control system.

I don't know much about BlindersKitten but the page says it can receive OSC. OSC was originally for sound applications but is common as a show control protocol today due to being fairly simple and open (much like MIDI-SC, a formerly common show control protocol based on MIDI). So conceptually OSC is likely how a show control system would send commands (cues) to BlindersKitten.

One such free OSC software you could use to control it (+ handle sound, video, etc as asked in GP) is https://ossia.io :) (transparency report: i'm the dev)
