Yes, I was the guy that created these expression maps and gave them to Steinberg. You can find my initial Expression Maps both on this site and from Steinberg here: Steinberg Hosted Expression Maps
Also, I will NEVER sell these!!! I have seen some of these go up for sale in various places. They were always supposed to be free and I intend to keep them that way. I am here to help out, not make a quick dollar. Musicians already have a hard enough time getting going.
Additionally, if you have any you would like to share, I am more than happy to put them up on this site and give credit where credit is due! 🙂
