Yes, an audio interface would be great!
I remember having to purchase a separate interface, monitors, stands, cables, etc. for the VPC-1, you know, because it’s “the best” controller in the world, yet somehow I was still underwhelmed despite its so-called ‘authorized’ velocity curve(s) for Pianoteq!
“An authorized curve,” I thought, “surely, it can’t get better than that;” well, it turns out that it can get better than that + a bag of chips; sans the cumbersome cables/interface & overall expense associated with the VPC-1 setup.
