Hi Diki
Styles are just Midi Loops, and any slides or bends are also done via Midi, therefore if you transmit this to a VSTi sound instead of the internal sound, then the VSTi will do exactly the same as if it was an internal sound. (Exceptions are voices that use articulations (Hence you never see SA voices in Yamaha styles) which may not react as expected, but you can usually turn these off)
Hope this clears things
