I used to use it, probly the best audio engine available, having said that, i switched to Ableton Live a couple of years ago and have never looked back, i do sumtimes miss the warmth of the Cubase engine, but not massivly, abletons audio engine is superb, and I havent put a huge amount of effort into tweeking Abletons render options, it has allot, and i recon its possible to get pretty close to cubase's warmth, even if not, a good mastering engineer is essential at the end of the day (although obv thats not sumthing to worry about at the moment). Anyways, Cubase is awsome, however its not 'future proof' imo, simply because it lacks elements like Live performance tools, which are pretty much essential for todays fast moving EDM scene, and although it has excellent routing, you cant beat the all-in-one feature set of ableton live suite for creative possibilities (synths and Fx are FAT), if you have cubase already, then use it, its fantastic, but if you havent decieded yet, check out ableton aswell
