Thanks for all the (constructive) input in this thread guys - I've found it VERY enlightening as I too am interested in the MS for my next keyboard.

This Question:

"Am i right in my understanding that it can hold a maximum of 4 VST's at any one point in time ? does that mean for example that you could have a VST bass , drums, guitar and piano in lets say style 1 but would be limited to use the same VST's in style 2 if you chose to use VST's?

If thats the case it makes the whole open system USP much weaker than i first thought as i would not necessarily want to use the same VST sounds in every style and certainly not want to be limited to just 4."

needs to be answered quickly and properly (IMO) as this is THE most important info I've seen in regards to the sounds and flexibility of the MS.

VSTs and Giga Sounds are all very well, but if you can only use them in a very limited way, then............
