Storage is not an issue for command stations. The P2K has a DRAM SIMM for loading the ROM information into so that ROM banks (and stuff) are loaded into RAM at system initialisation. If you had too many ROMs some P2K's with only 2 or 4MB of DRAM could not fit the additional ROM banks and so that entire ROM was 'invisible' to the front panel. You could still use it with user presets but not see the ROM ones. If you had 8MB (or 16MB) of DRAM SIMM then there was no issue. On a command station there is an 8MB SDRAM so this was never an issue. Maybe it would be problematic if you had 4 'ROMS' that had 8 preset banks each and other stuff, but we'll have to see about that.

The user information is stored on FLASH memory in the system which also holds the operating system. Different areas, so should not be an issue, but death of the FLASH might show up as an inability to store USER information or change it.

Slots are not an issue since the operating system references ROMS by an ID number which is not related to the slot. (so the same user presets work whichever slot the ROM they refer to is in).

There is no dynamic storage on the ROMs so multiple ROMs do not help with the user presets in any way. The only possible storage on the SIMMs within the P2K/command station is the storage of a bank of user presets into the FLASH preset memory of a FLASH SIMM that has been written in an ultra sampler.

thanks, Matt
may check into that, will let you know what i find out

question: i think it may have been you noting a while back of the lack of storage space in these machines,
so that is why you have no factory presets ? just wondering. also does having more roms in the machine ( my px7 has three) help in that department ?

thanks again
