Using input-selector causes thousands of calls to my fill functions, while my own solution yields 64 (which is still 2 times the desired result, given that I have 2 sources).</div>

<div>
<div>one sink will do - it must only be possible to switch it from one source to the other dynamically. I'll look at inputselector, the name sounds promising</div>
