Thanks for those links Bill. I need to clarify my understanding of how many VST sounds the Wersi can hold at any one point in time.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. Is there any particular reason for this limitation ? I understand the limitless updating angle of open systems and that the functionality of the board can be developed in the future without buying new hardware in terms of a board with keys but in terms of pulling the software and functionality together , are'nt you still tied to the proprietory manufacturer in terms of future functionality of the board ?

If i have misunderstood this can you helpme out ? I could find no data on the cost of updating to OAS7 (and no demo's of what the new OAS7 does ) but i read that it does come at a cost. Whilst i believe that this is a more sustainable business model for Wersi going forward, the MS promises that all future updates will be free to MS users. Whilst that does not mean a whole lot right now it could be a real deal breaker in the future once the MS has sorted out its current problems. Any idea what the cost of upgrading to the OAS7 might be in �'s.
