After the campaign a small number of us IOS musicians had to mount to convince Apple there was something seriously wrong with audio latency on the latest iPad Pros and get it fixed (now successfully) I got the impression that the IOS user base of audio apps is pretty small (and certainly nothing more than an annoying buzzing fly in the next room for Apple).
Here's a wild idea ... try selling a VST equivalent for the same price and see what happens to sales. Again, I don't have the figures, but I think there are many more desktop musicians.
The thing with IOS is that so many things come up in the sub £10 range that I, and others, just buy them and take a punt on them. There are quite a few misses but there you go. Nobody died. £20 I certainly think about more but if the dev's pedigree is good I may well buy it. There is definitely a culture of purchasing cheap apps.
Why wouldn't/doesn't that translate to the desktop? Genuine, economically naive question.
And I rest my case, since I don't want to derail the thread.
