Hi Shim,
I've got mine up & running with my Korg.

Did ecounter a couple of problems , though.

Combination of Korg for sounds for the style tracks, OMB as Arranger, Garriton (stand alone) for melody voices works ok.
When I tried the same combination with Kontakt I ran into problems.

I use midi yoke for virtual midi cables. Garriton recognized it in 32 bit mode, Kontakt doesn't recognize it so I'm guessing it's 64 bit??

There is the option of maybe loading it into OMB as a vsti?? I didn't have a great deal of luck.

I ended up reloading my Brainspawn Forte software that I used to use for my softsynth /software arranger setup.
It's now working perfectly.


As for possibly midiing a keyboard to play styles parts
& softsynth for melody, no hassles with my korg, I may even be able to get it to do bank & program changes for melody & save as a performance.

With the yamaha , you may have a few more hassles, you may need to have to choose them on the pc.
I remember I ran into problems a few years back, when I was trying to use an sd2 midied to my psr1500. I couldn't access all the sd2's sounds.
