There are so many new Instruments with Kontakt 7 and ultimate that have the option of up and down and left and right for morphing the sounds. Why wouldn’t we be able to automate those movements with a mouse? It seems like a no-brainer to me and much easier than setting up two different midi controllers. Just put the track and record, roll the track and use the mouse to position the sound up-and-down and right and left controllers easily.
