PC has a nice feature too -- where uploaded wav file audios allows users to click on the audio. And there are cases - where something occurs where we click on the wav file link/name to play the audio, but the software algorithm hasn't been set up with the equivalent of contact-bounce elimination …. so we sometimes hear two of the same version of audio being played simultaneously. And if the amount of delay happens to be just right, the timbre/tone of the piano sound can be very different from the original sound - even rounded/muted-like. Quite nice. But if the delay happens to be a bit too long, then you can hear distinct repeated note-strikes (which is what we expect) - which doesn't sound so nice.
Some people may have encountered that already on PC. It doesn't happen all the time though. Just sometimes. That is - this double-play (overlap of two of the same wav files playing over themselves) condition just happens. I haven't found a way to produce that condition manually - to make it happen whenever I want. At the moment, it seems to happen by chance.
