We rarely use Cakewalk but while our primary machine was down, we had a chance to mess around with an SD1000 and Cakewalk instrument mapping. If you use Cakewalk and have an SD1000 check out a short video we put together showing it in action:
SD1000 and Cakewalk *.ins demo

You can download a copy of the *ins file from our site. We are working on a *.ins file for the SD40 and will update when we have it fully coded and tested.
