ok. the start tag indicates the length of the pregap. if you're making a
redbook cd, you'll have your first modulation at 2 seconds exactly. the
start tag will read 2 seconds to indicate this (if your range starts on
the modulation), but the file will be used from zero in this case.
the first track's pregap is never played by the CD player. you can,
however play it by rewinding past the beginning of the first track.

for the second and onward tracks, the pregap only plays if you're
playing continuously through the CD. if you skip tracks, each track will
play from the start tag. this provides another way of 'hiding' sections.
some labels put the start tag on the beginning of the single's vocal,
for instance.

so to get a pregap, don't butt up the ranges. leave a gap. the pregap is
determined by the end marker of the previous track.

i think this is a good feature.

i think the patch fixes this completely.
