I am in Logic, and I have a Keystation 61es. Is there a way to split a keyboard? I have an idea, but I do not know if it is possible. I would hit the R buttons that make 2 sounds play at the same time, and then assign those sounds ranges. For example, one range could be from C1 to C4, and another could be from C#4 to C8. Is this possible? Is there an easier way to do this? Thanks!
