I need to buy as near to a piano touch response keyboard as possible and I think that NI Kontakt might be the answer. I really just want realistic acoustic instruments that I can manipulate to sound as close a possible to a live player in front of a mic. So I'm confused about add on stuff such as Komplete 15. I don't really want automated functions that are like a sophisticated single finger chord function. So do I just get the hardware i.e. the keyboard and leave the rest. I'd also like a real-time MIDI controller for accurate expressive crescendo etc dynamics. Starting from scratch , what should I buy. I use logic for sequencing/scoring. The only plug-in I have is Spitfire intimate piano which I love. Does NI make acoustic instrument libraries?
