From the Poly800 MkII manual:
2. RAM data structure.
∗The RAM data portion of DATA DUMP data is organized as shown here.
DATA RELATIVE ADDRESS BYTES(decimal)
---- ---------------- --------------
MIDI CHANNEL 000H 1
SEQ DATA 001H~3E8H 1000
(UNDEFINED) 3E9H~3F0H 8
CHORD MEMORY 3F1H~3F8H 8
SEQ MODE 3F9H 1
SEQ CKL 3FAH 1
PROG CHANGE DIS/ENA 3FBH 1
(UNDEFINED) 3FCH~3FFH 4
PROG DATA 4O0H~A7FH 1664
∗Actually, when this data is transmitted on MIDI, each byte
is split at its least
significant four bits and sent starting from relative
address 000H.
(UNDEFINED data does not affect internal operation; it is
only used in the check sum.)
