Understanding Preset and Register Indexes
Presets and Registers share a range of indexes to represent locations within the 480 software. All indexes are in
the range of 1-1023. The range 1-923 is reserved for presets. Currently presets 1-210 are available. Indexes
between the range of 924 and 973 are internal registers and 974 through 1023. These numbers are used in all
automation or bulk dump sysex messages when referring to a stored or preset 480 setup.
The following equations define the locations in the array:
Presets
index = (bankNumber - 1) * 10 + (programNumber - 1)
where "PGM0" represents programNumber = 10
Internal Registers
index =(registerBankNumber - 1) * 10 + (registerNumber - 1) + 924
where "REG0" represents registerNumber = 10
Cartridge Registers
index = (cartridgeBankNumber - 1) * 10 + (registerNumber - 1) + 974
where "REG0" represents registerNumber = 10
