Sequential circuits samplers

>>The architecture of the 1MB seems to be really 512MB+512MB, with no path between them at all.<<

I'm replying from memory, but I used to be dead good at this... :-)

that's exactly how it works. to use the entire memory for one instrument patch, you should load the longest samples first, & work alternately like this:
sound 1
sound 16
sound 2
sound 15

& so on until you are putting the highest-pitched/shortest samples in sounds 8 & 9. 

then make sure you are using a keyboard mode that has access to both sides. "LA" I think... or "ME".... either way, the keymap boundaries will make sure that only one sound is heard at any given time. 

an alternative is to build an instrument in the "A" side using sound locations 1-8, & another in the "B" side using 9-16. then operate the machine in midi mode 3B with the two sides on different channels. this is about as multi-timbral as the 2000 gets, unless you work in mode 4 which puts each sound location/sample on its own midi channel.

this help any? btw, it's the same rules for the non-expanded machine.
