Sorry, but I always felt that, although Technics did have more contemporary styles, they just weren't as good as the 'oldies' stuff, and didn't match up well against Roland and Yamaha or Korg if you NEVER played 'oldies'.

They simply had a 'focus' to their style selection, same as Korg have the 'smooth jazz' focus, and Roland have the hiphop 'focus'. Every arranger does one or two styles better than the others, something their style developers really nail... For Technics, this was bigband music. And many of the players here that STILL use the Technics probably use them simply because there is still nothing better for that style....

All JMO, though....
