what do I need to download as a pre-requisite in order to play the above package.
Hi Giacinto, besides purchasing a ViennaKey, the standard version of Vienna Instrument player is included, just you need to downlaod it separately —also with standard Vienna Ensemble—, so you don't need to buy any further to start.
Can't tell about Cubase issues.
Hope it helps
I wish you a Happy 2017
