I don't mind nexus but I know that some people aren't a fan of the lack of control you have on the sound. you can add fx but that's it you can't change the actual wavetables.

^ this is what im thinking about ive always felt like im cheating when i do this but i think its just a way of thinking thats counterproductive

Nexus is great, fact you can just throw it in and some really well designed sounds available instantly, I use it a lot. The only downside is that it can be quite expensive once you start adding the expansion packs. I'd say its worth the investment only if you got the cash for it.

You're the reason i started second guessing my opinion 

Why not use Nexus? Nexus is like using presets.

I use Nexus to layer my pads.

Yeah, nexus can be a great tool for layering pads, leads, even plucks, but the sound themselves are usually meh.

Some of Nexus' sounds are fantastic and can't be matched by other synths.  Some of the orchestral sounds, and screaming leads are fantastic.  When I want a sharp, fat, top lead that will bring out a melody, I think Nexus.  I understand why someone would take heat for building up a track that is built of entirely identifiable nexus sounds... but layering the plugin and weaving it into your track should be no problem from a musical, and creative standpoint.  (As you're saying)

We always have to keep in mind that so many people who are fans of music don't even know what Nexus is.  Still, I'll stick with "layer it in".

Not worth it IMO.

Money can be better spent with a few KONTAKT libs
