Well you have redefined add, thus your initial script was in fact
correct, including the "new source should come first in add([])" bit..
Could you try to add some printing in your default transition so as to
check whether your default function is executed or that the problem
comes from elsewhere. Something like this:
default = fun (a,b) -> print("\n\nDEFAULT\n\n") add(fade.out(a),fade.in(b)),
