3-3 Memory Banks
The E5ZD is equipped with memory banks that allow you to change many oper-
ating parameters as sets. Some parameters are independent of the control point
and determine overall E5ZD operation. Others are set by control point and are
independent of the memory bank being used. The remaining parameters are
contained in the memory banks.
