Hello,
If you use readsf~ connected to two subpatches with switch~ in an abstraction it doesn't work. If you open this file as a main file (not as an abstraction) it works fine. If it is used as an abstraction it starts to work from the moment you move or connect an object 'downstream' of readsf~ (while the file is 'playing'). From then on the readsf~ and switch~ work well.
Have a look at the file in attach, I can't explain this or am I missing something?
(tested this on pd vanilla 0.41.4 en 0.40.2 on windows xp)
