Yes, indeed, you're very close to a possible solution !
When I try it here with 0.9.2, it works very well, though. I am using a
playlist for the input, perhaps it depends on the source..
Anyway, you may want to use a fade.in on the next source (or perhaps better a
fade.initial, since this operator does not care about track limits).
If you use an exponential shape, the begining of the source will be almost
zero and it will quickly increase. Something on these lines:
def livefade(previous,next)
add([fade.in(duration=2.,next), fade.final(duration=2.,previous)])
end
def backlivefade(previous,next)
source.skip(next)
add([fade.in(duration=2.,type="exp",next), previous])
end
Also, I can confirm that the fade.out transition does not work on harbor. I
suspect this comes from the fact that the fallback does no see enough in
advance to be able to trigger the transition on time.. Raising the buffer of
the harbor input does not help apparently...
