Hi Bob,
Thanks for your continuing interest & help.
The previous thread you referred to relates to a replacement cable, rather than a new item.
My current setup (which works fine) is as follows:

Casio WK1800 keyboard -> Edirol UM1X interface - 1 DIN into Casio & the other into -> Ketron SD2. The USB from the interface into the Toshiba laptop. Ketron via RCAs to 3.5mm lead into line in of laptop.
Laptop headphone out via graphic equalizer into amp.

I've had the Ketron for a number of years now, and I absolutely love it. The sounds it produces, particularly the higher bank patches are great, and combined with Real Tracks, they make a simple piano player like me sound half good smile

I'm hoping that the solution will be simply a lead with RCA stereo jacks (from the Ketron) and a USB (to the new laptop).


Cheers,
Keith
