Looking at the original crossfade logic, it would act as you describe
using Shuffle and Manual Skip, but the manual seemed to describe it
differently. So I used the AND logic when rewriting the decision tree.
I'll fix it back to an OR decision and rewrite the manual to make it
clear what's going on. Maybe the option ought to be "Shuffle Or Manual
Skip", which seems closer to me what's going on.
The new "Auto Track Skip" option was put in on request, so I'd like to
keep it. And if I were using crossfade I'd probably use it the most.
(Since I mostly listen to gapless albums, I don't use crossfade, though
it would work great for compilations). The idea here is to crossfade
for all track end situations, radio station style, but if you want to
skip a song, it happens right away without crossfading. "This song
Speaking of manual skips, I noticed that crossfaded manual skips are
handled precisely the same way as track-end crossfades. That is, the
fadeout happens *at the end* of the currently buffered material, which
is then mixed with the faded in new track. This means that even after
the skip button is pressed it can be a couple of seconds before the
crossfade start sample is marked and the fade out delay begins to count
down. I propose that the fadeout delay counter should begin immediately
for crossfaded manual skips. I don't foresee any objections to this,
but I thought I'd ask.
I'm still torn on the "Auto Track Skip" verbiage. I tried to make it
clear what it is in the manual, but it's not very descriptive. Even
something like "Natural Track Change" doesn't quite nail it. "Track End
