My screen is a razor sharp 14" monitor with 1024 x 768 pixels. Resolution is not the issue, just size. All the text on the screen used for the demo is just a total blur -- I can't make out even a single character. I'm a long time, full-time computer user, and that text was by far the worst I ever saw that was intended to be read.
2)-4). Your video doesn't have to be "self contained". Instead, just say in broad terms what you are talking about.
I've never heard of AudioKit before, nor should I have. I have no idea at all what the purpose of AudioKit is, nor should I. I have no idea if there is a Web site for AudioKit or if it has tutorial material, nor should I. If all such things are true, then make that clear.
E.g., could I get the orchestral score to the R. Strauss Einheldenleben and use AudioKit to do a good synthetic orchestral performance? The score to the Bach Chaconne? The Bach solo violin version? The Busoni piano version? Say enough to make answers to such questions clear.
3) Ohio. Ohio should be fine. My mother was from Columbus, grew up just south of the OSU campus. I was a prof in the B-school there. My father went to Ohio State, BA and MA. My wife was from not far away, about 50 miles SW of Fort Wayne, IN. It's not about Ohio.
Instead, just do what I said: Don't drop your voice at certain words or at the ends of sentences. When you say a word, go ahead and actually pronounce it. Your Ohio version of English speaking is fine; just use it. As it is, mostly I couldn't understand what you were saying, totally lost maybe 1/3rd of your words and more of your content.
Since I couldn't read your screen text and couldn't understand your speech, I gave up, and I'm someone really interested in music, really interested.
You may have some good work. If so, then good. In that case, speak up, describe your work, show clear screen images.
BTW, I have no idea, none at all, zip, zilch, zero, nichts, nil, nada, what the heck "Xcode" is. None. I doubt that Xcode is in Webster's. So, Xcode is undefined jargon. I know quite a lot about both music and computing, but I don't know what Xcode is, and likely I should not. Lesson: If you want to communicate, don't use undefined jargon.
Computing: I've published peer-reviewed original research in artificial intelligence from the IBM Watson lab. I've taught computing at both Georgetown U. and Ohio State U. At Ohio State, I was a leader in computing in the B-school and more generally on campus.
I've programmed significant software for decades. My Ph.D. dissertation was heavily based on software that I wrote.
I recently finished typing in software for a Web site with 4 back-end servers, 80,000 lines of typing, about 18,000 programming language statements, for Windows with the Microsoft software .NET, ASP.NET, and ADO.NET and for the Microsoft calls for TCP/IP, etc. Still I never heard of Xcode. Fonts? I'm quite good at D. Knuth's TeX, still have never heard of Xcode.
I'm not attacking you. Instead I'm giving you constructive feedback so that you can communicate better about your possibly quite good work so that many more people can like your work.
Main lesson: Just speak up.
