For your general information.

I bought EMC's Technics style upgrade Disk for my 6500 when I had it.
It was to read the style disks of the following keyboards.
Korg i30,i40/50
Roland G-1000/EM-2000
Soltan Ketron X1
Yamaha PSR-9000/740
It converted all with no problems except Yamaha. The main reason I bought the disk.
Very few of the Yamaha convertions were usable. To me it was totally useless for Yamaha styles.

I am wondering if it is the same disk Techplus is selling but for the 7000.
