What software are these producers using to make dubstep?
Are they using some kind of software that drills the basslines, or are they just tweaking the parameter knobs in normal software. I have Massive from Native Instruments Collaboration Software and was just wondering if I'd be able to do the same.Anyway, I want to share some of technics and advice with people, as I think it could help out people quite alot. Im not a professional by any means, but as I said, i've had good feedback and i'd like to share my thoughts on the music making process with you all.
