But parent hasn't acknowledged that you were an inspiration. I find this insistence quite rude. Especially when it's taking well trodden ground in desktop software and putting it on the web.

Well trodden ground? Except there wasn't desktop software that could do this beforehand.

If you can't see the innovation, let me spell it out for you in very few words: the software has an intuitive-enough UI that you need no prior knowledge of the program to use it, and you can share musical ideas in one or two clicks. Please tell us exactly which desktop program allowed you to do this, as easily, pre-2012? Yes, this is novel, since it enables something that wasn't possible before.

This kind of simple edit and share songs definitely existed, e.g. Otomata. So you combined Otomata and Tone Matrix? Cool, I guess, but the ingredients were right there for any number of people to do the same thing independently.

Trying to claim your place as the trunk of the tree that any tool that looks like this branches out of is not reflective of reality and pure hubris.

Also I'd appreciate it if you added a link on Music Toy for both of these apps which clearly gave you inspiration.

Why in the world would the author lie to market for you when you weren’t an inspiration?

I think it's very likely that he has seen one of the multiple music apps I've put out over the years and has actually taken inspiration from it. Either way, it's not required, but considerate to acknowledge your predecessors. Particularly given that the concept is pretty much exactly the same.

I was not aware of any of the music apps you made and came to know about MusicToy first time from this thread (oh and it's great btw, I played around with it a bit)

and my inspiration, as I stated earlier was from a stress-reliver app in play store which I have given credits in the first paragraph of README.
