DR-770: Changing Pad Banks
Each Drum Kit on the DR-770 consists of two Pad Banks (A and B). Each Pad Bank consists of 16 sounds, one per each of the 16 pads. Use the following procedure to change Pad Banks:
1. Press PAD BANK to display either "A," "B," or both.
Note: When both A and B are selected, you will hear both sounds layered together.
