Composing, even electronica, is also "live" unless you're doing it in a MOD editor from the 90s.
When I'm playing my electronic drum kit using Hydrogen to provide the samples, BELIEVE ME, there is a very very noticeable difference between hearing your snare strike 10 ms after your stick hits the pad and 50 ms after your stick hits the pad. 50 ms is still playable if it's consistent, and if you practice at it a bit - some people use Windows, after all, so it obviously works, even if it's not ideal. :)
But 100 ms is not usable at all. A tenth-second gap means there is no relation whatsoever between the part of the phrase in your head (that is currently being conveyed through your hands to the equipment) and the part of the phrase coming into your ears and being interpreted by your brain as "what I'm playing right now." You can't force half of your brain to work 1/16 note in the past at the same time as you play what you need to for the present. It just won't work.
