Peter,
You cannot transfer individual voices or styles directly from the Technics to the 3000, however, all of those styles have been long since converted to Yamaha format--and they can be loaded.
Additionally, follow the advice of those who have the 3000, explore the keyboard thoroughly, tune the EQs, and more than likely, you'll find similar sounds to those you had on the Technics. There are hundreds of individual voices on the 3000, many of which are in folders you are likely not aware of their existance.
Tune the board's EQs first, then look at all the wonderful sounds you'll find in the depths of the board's inner workings.
Cheers,
Gary
