I am a big fan of the korg sound myself, i own a kronos and would not want to miss it for any money in the world. The krome has the same hd engine as the kronos with a lot of the same samples..

Korg instruments have great sounding pianos, epianios, organs, synths and synthpads and electrical guitars.. Strings and acoustic guitars are good and can be tweaked in any which way you want, but.....

Acoustical instruments like saxaphoness, trumpets, trombones, flutes are in my opinion way beyound yamaha and roland if you want to play them naturally in a live setting... And i dont see a huge investment from Korg either, as most pro musicians realise that for recording purposes its better to get the real deal...
