I can appreciate what you’re saying Gavin, but I too would greatly like to see this happen. I know it must be challenging, as almost no synths from most developers at any level do it. Still, a live implementation is highly desired and would certainly place the already amazing Circle synth above the crowd.
Half of the reason I’d love this is that often you find an amazing patch that is close to perfect, but doing something unwanted that you want to be able to quickly see and eliminate, and it’s sometimes nearly impossible to find out what is being modulated and causing the behavior.
The other half of the problem is purely the ability to easily validate that what you believe is being modulated in your own patches actually is. Sometimes it’s because an automation lane got wiped, sometimes it’s because bad midi or CC data is getting sent that you’re not seeing, and sometimes because you accidentally assigned the same control to two different parameters.
Mouse hover is something I hadn’t heard before, but it would be of very limited value to me for the majority of what I want.
The last thing I’ll say is that out of 70+ premium soft synths I have owned and used, it is this one feature that always makes me realize why I’m still looking at all.
