Plus, how is it more intuitive to browse into some obscure system folder to open preset files when the task of changing the sound is offered where 99% of all users expect to find it - in the GUI of the instrument whose sound you want to change?
If you sit 100 people in front of the plug-in, where would the vast majority of users go looking for a way of achieving their goal without consulting the manual? That's what intuitive means in regards to usability.
No, I get it. But my response should easily be understood that I was having issues trying to get to other presets (and I read another on here having the same problem, too).
Instead of criticizing the new user, it might help to take a minute and ponder "why did the new person endeavor to do it the Windows-way rather than the built-in user interface way?" And you could have guessed it that the interface isn't as easy and intuitive as it was thought to be. That's all.
Once I learn the ins & outs of it, after having tried for several minutes and failing, it will be okay. Just a quirk about the design that you'll forget after a while, but all new people are sure to face the same dilemma when they encounter it.
Sorry, I still don't understand what you're saying.
Yes, I disagree with you on everything you said. That's life, we can't always agree with everybody.
Especially what you were saying about the choice of colors in Windows XP and that being in any way a good idea and somehow based in extensive user testing - just because you state it like a fact doesn't make it a fact. Windows XP's default UI is not objectively a good UI. It may be pretty to some and definitely colorful, but not objectively a good UI for a working environment. So I'm really glad somebody else made the design decisions for Zebra.
But seriously, I can only reply to what you write, not what I should have interpreted into what you were saying. If you have issues with the browser, you can state those issues and perhaps a discussion will follow, perhaps even a solution to your issues. But instead you were asking for u-he to support a way of bypassing their new feature and allowing you to use Explorer instead of the browser. And that is why it was suggested you try reading up in the documentation first. That, plus, as ED said, there is no way your wish can come true. You can only define the default application per file type and plug-ins aren't standalone applications.
Look, the preset folder is installed inside a folder which is not necessarily apparent (= obscure). On MacOS, it's /Library/Audio/Presets/U-he/Zebra2. I can only assume it's something similarly hidden on Windows. Most users, rightfully, never get to see these folders unless they're instructed to in order to troubleshoot.
So if a user wants to load a preset, I still don't think it's easier to find out that location and switch over to Finder/Explorer than clicking the left/right buttons adjacent to Zebra's display for a start.
And in order to load a preset, the user clicks the very prominent PRESETS button in the GUI and takes it from there. It's a convention across a great number of soft synths. Probably including the instruments which come with your DAW.
