Their Phaser/Flanger algorithms still seem so good! No wonder for KORG as the very first ones with internal FX in synths like DS8 & DW8000 around almost 40 years ago. They have anything else but disgraced themselves with their art of engineering. Even today DS8/DW8000's Phaser/Flanger/Chorus sound so much better than f. e. a whole certain low cost (still kind of usable) multi FX unit from around the millenium. One prbly. knows who/what's ment, with "low cost"...
