Bacus, you are an expensive influence on some of us on this forum!!! That Nord keyboard is very appealing! Your idea of using it with an SD40 is good, too, though I like using vArranger. As expensive as it is, still it is not even half the cost of any high end accordion. I am looking at an Bugari Evo - a Roland digital accordion in the body of an acoustic accordion. The Evo is over $7,000. I know that the Roland V stage digital piano is $7,000.
