[sgroup] s550util question: Raw mode sample extraction vs default (non-Raw mode)?

Hello everyone. I'm archiving my Roland S-330 samples. I'm using the *s550util* that Peter Heitzer developed. For those that don't know, this is a utility that runs on Linux at the command line. You can use the linux 'dd' command to create an image (.img) of a 3.5 floppy disk. Here is a link to Peter's software for those interested: http://homepages.uni-regensburg.de/~hep09515/keyboards/download/s550util.tar I have extracted the same tone in raw mode (-r) and with the default. They are different files, but I don't know what the difference is. Perhaps someone here knows the difference? What purpose does the raw mode serve? s550util v. 1.01 (Jul 26 2015) (c) 2004-2006 Peter Heitzer Usage: s550util -h|-l <file>|[-r] -{x|X} <file> [s1 .. sn] -h: show help -r: raw mode, ignore tone start and end points -l <file>: show info for image <file> -x <file> <s1> .. <sn> extract samples s1 .. sn -X <file> : as -x but overwrite files Sample numbers are in Roland notation, e.g. 11 for first sample. A range of sample numbers can be given as <first>-<last>, e.g. 14-16. Only original tones can be extracted. Thanks in advance! David A. Roth
