The following pages list all 1,235 registers, or stop-keys, on the seven-manual console. The color of the engraving on each register is shown and couplers have a gray or black surround, as appropriate. Stop numbers - to indicate derivation - are engraved at the top of each register. Great care has been taken to ensure that the order of stop-keys and what is engraved on them is correct. Therefore, names such as "Saxaphone" and "Miramba" are actual spellings, not typographical errors. The order of registers is from left to right on the right jamb, and from right to left on the left jamb. Although the vast majority of the 852 speaking registers are associated with the instrument's 96 extended ranks, it should be noted that 353 (79%) of its 449 ranks are straight.
