I have an Essential 49, and a SparkLE. It's great having the 2 different controllers, but after I've done some work on the drum machine, I'd like to not have to keep going back over to it just to hit play when I'm zoning on they keys. I'd like cross functionality with software and hardware, where applicable of course.
But to be able to use the pads on my keylab to trigger the ones on my spark would be awesome and beneficial in the creation process.
