Only a handful of often out-of-date controllers are supported with templates in Studio One Pro v3.
A huge number of us already own affordable and extremely capable midi controllers that are made redundant in many ways due to your lack of support, but more importantly, you are not even giving us the option to do it ourselves, even when all the functionality is there under the surface (pun intended!).
You should be reaching out to hardware companies to make sure that Studio One supports a broader range of devices, for one, but for those that aren't supported with preconfigured templates, give us the info to use the tools to get it done!.
I appreciate that you want to sell your own controllers, but do you honestly think that by refusing to acknowledge the fact that we use other brands, that we'll suddenly turn around and drop £1,000 on yours?
Get real Presonus! You will grow by embracing diversity, not by acting like Apple and trying to coerce people into living solely within your ecosystem. This is not the way the world is going. You need to face up to this! You breed loyalty by being open, not by being subversive. Give us the XML!!!
