Thanks everyone
yes the one I was thinking of is PSRUTI by Heiko Plate. I used to use a bunch of those great free utility programs I just couldn't remember which one was which.
I can't seem to download the latest PSRUTI from the link provided.

I'm gonna try and find one that I can find to revoice smf to the s 700. When I had the tyros it came with a data sheet that gave you the midi numbers for all the voices, I can't find a similar sheet for the 700 so I was hoping maybe there is a program that has the map loaded.
I, of course, want to use the sweet, live, and other voices rather than just the gm set.
I also would like to edit them on the computer.
