Is it possible to use bpm for times? including effects etc, I work almost everything with a metronome and it’s essential for me to work everything in bpm.

No that is not possible in Onyx. Lighting consoles in general use absolute time values . I’m not aware of a desk that allows to set a cue fade time in BPM.

MA, Chamsys and hog use bpm, is the only way to sync effects with a metronome
