Sequential circuits samplers

hallo Duncan,

I did read the infosheet as well.  no sign of any design changes or different versions as you mentioned.

still I have seen at least 3 different versions by now.

they are interchangeable and there seems to be a difference in volume and soundcolor as well.     still all of them are killerchips ; )

anybody with knowledge about these chips ?

cheers,
David
