Searched everywhere for such a tool (sampleplayer) - finally found this one! There is nothing like this in the net. I love it. It runs on my 5500 Sport (but my display is not large enough).
I use it for triggering sound-effects for fun, but could also imagine to use it as a DJ-tool (connected to a PA-set) or use it as a "horn" in a busy pedestrian area ;-)
Also possible: As a simple music instrument with different pitches
