Mockie,
Sorry this topic is going North towards the Roland's Integra-7
Coming back to the strings in a module, if you could find a used Roland xv 5080
it would still make the cut for rich orchestral string sounds. Or even the used Motif series racks have great string sounds.

For software, the list is huge with many offerings like those from east west quantum leap, ik multimedia, native instruments etc.

Good luck in your search !!
