with about 10 lines of python (plus a few to name the presets you're after) you can do such tricks with this little helper here: http://quitte.de/file-formats/SF2.py at the end of the file it shows how to extract one preset into a separate .sf2; modification for many presets/sf2 files should be straightforward. cheers, tim
