not sure it's worth the trouble.
Yamaha's don't act as a very good keyboard controller.
I did a lot of experimenting with my psr1500.
To choose external melody sounds , it had to be done , in my case, in the soundmodule itself. The bank & program changes the psr sends won't necessarily match the program & bank changes for a module or a softsynth.
If you want the softsynth to play the style parts, you're going to have to alter the styles bank & program changes to suit the softsynth or module.
Also , with my PSR1500, it was a case of either the module playing all the style tracks or the psr playing all the tracks,
the midi functions didn't allow me to pick & choose , what played which tracks.
Bill's suggestion is interesting, I've never tried Kore, may look into it myself.
If you really want to give it a try,
find yourself a free xg or gm soundfont bank.
There's a demo version of SampleLord available for download. It loads giga samples, soundfonts plus some other formats. Reason I'm suggesting soundfonts is, it's a complete bank.
Might just give you a rough idea of some of the headaches you may encounter, before you spend money.

I'm wondering how you guys use a laptop as a sound source for a yamaha keyboard.
In other words, I want an additional sound source from the computer so that the psr s710 sounds better.
I know about Virtual instruments, but how would I be able to use in live setting?
