If you are using safari in iPhone, please try switching the download page to desktop view page by clicking the icon with square with arrow pointing up bottom menu in safari, then click download button.
If you are using safari in MAC, i am sorry i dont own MAC so let me have time to figure it out, but in the meatime, please try other browser if you could. Though, I can download it with internet explore in windows.
Could anybody using MAC confirm if it is able to download AU version with Safari?
Pro Tools doesn't support VST plugins natively. Because of this you don't see any of your VST plugins in Pro Tools, even if you've set the path to the right directory. Pro Tools only can use its own AAX-Format and for older versions of Pro Tools its own RTAS-Format. There are workarounds, f.e. with ReWire, but in general Pro Tools can't use VST plugins, so you unfortunately can't use this plugin in Pro Tools (as usual as in other DAWs) as long as the developer don't bring out an equal AAX- or RTAS-Version.
The idea of designing a plugin which does that is great. I wanted once to create a cool clock ticking effect like Martin Garrix does at the intro of "Animals". He also used a sample or in my case samples as everyone else and arrange them along the bar and beat counts to create a tempo synced clock ticking effect like that. He used a reversed tape stop effect also on it. You can watch how he used this at "Animals" here:
