Hi Audrey.
Yamaha will not read Technics files unless it is midifiles (xxxxx.mid)
To load and play Technics styles at Tyros5 or other brands, it has to be converted.
This conversons are often done by use of software like EMC Styleworks.
However, some keyboads, such as Korg (and even some Technics keyboards) have this convert feature as addon disks or onboard feature.
Convert songs from KN sequenser is far more complicated than convert styles, but songconversion I have never tried.
If recorded and saved as midifile, it should play on most all midicompatible units.

There are some Technics styles already converted for Yamaha at PSR Tutorial, maybe try some to see how it works out? :
