I was introduced to KN6000 and Solton X1 at the same time. I tought it is the best. But after hearing the Solton X1 instruments and patterns I was no more sure about Technics . I still have my KN3000 waiting for suitable time to transfer the files from the hard disk.
File copy one by one takes much time.
KN5000 hard disk is not compatible to KN6000, shame. I liked to have the HD as standard from Technics, not from third party supplier, voiding varranty if installed, the hard disk option is also far overpriced. Only KN5000 formats were usable. Most recent keyboard models have sampling or wave input but not KN6000. The computer interface has not had any progress.
