Bending Chords and Key Sig

I was listening to a few 80's tracks and came across something I'd like to experiment with but I am not a great keyboardist, but I can play a bit, basic two handed stuff and enough to get by in order to correct later but to the point, I hear these chord bends and pitch modulations typical with 80's stuff but how do you play it and do it?



I'd like to give you a certain point but it's all over an old fav of mine here: http://ift.tt/1taqBe6



How do you do these chords that require 2 hands and the mod wheel live? Chord memory? I can't work with chord memory like that co's the intervals.



Bendy chords that always sound diatonic? How to do?
