If for you is really important switching from style to style and sound to sound WITHOUT ant latency, then I will make a new Video and show you that the MS is able too, like the all embedded keyboard.
I have only to choose the right style without big GIG sounds or only styles developed under GM/GS, like the all normally keyboard.
Who will tell me that I MUST use the Midi-Audi-Giga styles IF I need to switch in realtime?
I can use the MS like a T2, without any type of latency.

So..I'm honest again:
1) If you want switch in realtime styles without latency, you have to use the MIDI styles
2) If you want play big Midi-Audio-Giga styles, you have to waiting for the preloading time and the switch latency.
The Mediastation is working only in this way, so..before someone will order one MS now he know the status.

About the big musician, you will see SOON who have ordered the X-88 for the concert, bacause is the only keyb that allow you to play GIGA, synth, Vst in realtime and they don't care about the 0.5sec latency when they switch engine.
