I've already said most of what there is to say about the event itself here, but what I only mentioned briefly there is that it's been a long, long time coming, with the project going through metamorphosis again and again. I had a need to do something that would contribute to bringing the world of music back around to an appreciation of the role of harmonics in melody, not just in harmony, or at least that's how it began. Arguably, I've accomplished that.
Along the way it also became an issue of pride in craftsmanship, as an amateur programmer with experience in Apple's approach to supporting application software. That and avarice may collaborate to drive the project further, perhaps much further, but for now I have a sense of contingent satisfaction, the degree of satisfaction being contingent on the degree of traction my creation manages to garner.
Of course, a free app with no ad revenue doesn't do much to feed avarice, so I'm left with pride in craftsmanship, for now, which is probably just as well; it's what drives me to do my best work.
