It's really cool to have a stagepiano (Kawai Mp9000) in a rack format that goes to another Digital piano (Yamaha GT20) I guess Chris liked the hammer touch and look of the GT20.
You can hear that the sound has being a little processed over the years if you compare The Scientist live from Montreal 2002 and The Scientist Live from the Mylo Xyloto tour.
With my new Kawai EX Pro sample library I finally got the sound that reminds most of the sound from Live 2003 concert (A Rush Of Blod To The Head Tour) When I play Politik, The Scientist and Life Is For Living It Sounds kind of exact ;)
I think this have to do with the fact that Kawai Mp9000 is sampled from a Kawai EX Concert Grand and my new plugin player is also sampled from that same concert grand.
I just decreased keynoises, pedal noises to make it sound cleaner. Then I increased the tone, sustain, compression and added some exciter and a small concert hall reverb. I did some EQ as well, but very little to keep the whole 88 keys really balanced :)
I can upload a video when I use this sound in short. I have a youtubechannel, just search for "moonchild89" I have som Coldplay covers there. One has an original sampled Fix You organ and an explanation on how I did it, so you dont have to buy an old Korg Triton Rack ;) The piano I use is a Yamaha CP300, like the one Chris Martin used on absolute radio.
Cheers!
