Hi Fred,
Choosing a name is hard and cannot be the best for everybody. My idea was to focus on a weird instrument or something that reproduce sounds, and I discovered the polyphone, a kind a gramophone but stereo. The first icon of Polyphone was based on this:
tse3.mm.bing.net/th?id=OIP.OJOgUm32N_p_R...15.1&P=0&w=300&h=300
Using this name sounded like a good idea since a soundfont is a kind of "vintage" format that reproduce multiple sounds at a same time.
The similitude with polyphontics is accidental and I have never thought of some kind of interactions. It's not my fault if we are too much on earth and that everybody is craving for the slightest visibility. I'm here, I have spent days to make an open source software for the world, and I hope people like it for the quality, not for the name.
For sure I never wanted to benefit of their notoriety. I tried their software once and nothing more than once since I wasn't even able to save a single soundfont. So their notoriety, no thanks.
