claudiu, I should learn to master your keyboard before tackling software sequencers and synths. These software packages are totally different to use than any keyboard arranger and judging from the many questions you've asked about the VA76 (they were all good ones by the way so I don't want to sound negative here)you'd end up asking far more questions with the likes of Cubase and Reason than you ever would with the VA76.
Good luck, Merry Christmas to you all
