Hi, I recently bought an second hand DSS-1. I already downloaden some 
disk images but the problem is that my computer cannot read the 3 720K 
disk I got with it. When I format a 1.44mb disk to 720k my diskdrive 
won't recognise it so I can't copy the image to the disk (using 
copyQM).

Anyone got a solution? Or is there a way to extract the images and 
load it via midi?

I use WinXP.

Thanks in advance,
