Hard wired input ports aren't such a big deal, many plug-in are built entirely in Motion and Vuo lets you step beyond that nicely. But yes, you're limited in what you can do with a custom UI.
All this is moot without FxPlug 4 support though; you can't release new plug-ins that don't work on new Macs.
Just popping back in to confirm that the new M1 Macs refuse to run FxPlug 3 modules built with Vuo, instead showing the error in the attached screenshot. Would love to see FxPlug 4 supported if it's possible.
It’s unfortunate that the rules have changed relatively soon after the FxPlug3 support was added, but there are many other developers in the same boat, and not many complex plug-ins are ready for M1 chips right now. Probably best to reach out to other devs to find out what the situation is.
