This is one of those old school 90's Korg synths. Successor of the Wavestation. It's made of aluminum so it's very heavy. That's not good news for any gigging keyboardist's back but fortunately for me I just keep it in the studio for recording purposes. It has some lovely sounds. Many of them are quite dated but have lots of character. I use it mostly as a midi controller with software on my studio PC.
One of my favorite. Strings, guitars and basses are great. I used a lot like a strings emulation and his pianos still very beautiful. Lot of synth sparkling pads and effects. Very beautiful.
Even though nowadays I am using this keyboard only indoors as a midi controller, I am still surprised about some of the internal sounds. This is a great instrument. It's built sturdy, the keys have a nice feel to it and it's reliable. I am thinking of adding this one to my live gear someday as a backup keyboard.
