TBH, I haven't used fruity loops in a very long time, IIRC it's similar to Tracker which I have used and what I use now is similar. Afaik what you can do with FL is build up the beat in the note grid using shot kick, tom, hat, snare samples and then route into VST effects. This mean if the beat isn't quite right you can edit it, and if the effects need to be tweaked as it's playing they can be, although I think you'll need to get a bit technical if you need to store the live setting of the effects in the track, maybe FL has a live record thing for this? I dunno.
