yeah rikard used a korg triton on TIC and RD. if your looking to buy a keyboard i would strongly recommend getting a korg triton extreme, its basically just the korg triton with a few new features. Ive had one for 6 months and it has brilliant tones and you have loads of freedom to edit the sounds etc... so as you can get the exact sound you want. you can pretty much play any type of music you want on it aswell which is a huge plus.
