Emu XL-7 & MP-7 User's Group

So, ferrograph is on the right track.  All E-mu *module* sound ROMs have 5 chips, 4 8MB chips for sample data and one 1-2MB chip for preset/riff/arp/etc data.  The original sound ROMs for the *sampler* series only have the 4 larger chips since the sampler can read preset data into memory from the big flashes.

However, the 4 chip sampler ROMs have little to do with this discussion other than that they won't work (but you won't really find them anyway).

As far as the module version, there are actually 3 combinations: All 5 flash, All 5 ROM, and ones with the 4 big ROM and 1 baby flash.  The all flash version is the only one you can burn with an E4.  The all ROM versions are what eventually comes from the factory.  The one with the baby flash (yes, that's a technical term) is used for initial production since the sound data is done before the presets, it can be sent off for manufacture and presets downloaded to it later.  Once the first batch is done, eventually they transition to baby ROM to save costs.

Theoretically, you could update the presets on the half flash versions, but you'd have to have the SIMMmaster3000.  You wouldn't, however, be able to burn any samples since the samples aren't in flash.

To tell the difference: any flash part I believe will say Intel StrataFlash on it.  The ROMs do not.  If all five chips don't say flash, you essentially have a non-burnable ROM.

PS. in case anyone's wondering why these chips are so expensive, it's because they're very, very fast.  They have to support 128 streams of 7x oversampled data.  That's 2-3 times faster than even the fastest CF cards on the market today.  At the time of introduction, they were as fast as computer main memory (60ns)!

there is something- a small but significant chip- on the "real" flash
roms that is absent from the "leftover" flash roms emu were shipping
towards the end of their hardware days. 
somewhere out there on another forum are jpegs of the three distinct
roms I have encountered- the "real" factory roms, the "real" factory
flash rom that can be authored in an ultra & which will work in the
proteus chassis models, & this third sort (which comes in several
shapes but is basically the same) which seems to be flash rom with one of the chips missing.
