Back when I was using romplers like the DPM series...I came across a program called Sample C by Richard Evans that I used as a sample librarian. This is essentially just a nice front end for doing SDS midi dumps and recieves and saving/loading them from disk.
It was nice that I could easily build complex batch uploads.
I'm having a hard time locating SampleC on the web...will get back if/when I find it.
Is this what you are looking for?
