Looks like Roland is also here in these forums.
Personally, I have more generally pushed on Twitter @Roland_US, not only for their mixers but most importantly for their synths and modules, which most usually have proprietary drivers meaning no compatibility with iOS and strong dependance on driver support (eventually means obsolescence in a few years because off the lack of it).
In most cases, it’s not justified by any crazy feature that wouldn’t be possible in class compliant devices.
A good example is the Rane Seventy-two, which does have advanced features such as dual-port DVS capable sound card and displays integrated with Serato software , though it does at the same time provide a class compliant interface.
A good counter-example is Pioneer who always puts proprietary drivers to their higher end mixers and controllers without any real technical reason other than controlling the product lifecycle (a softer way to call ”programmed obsolescence”).
Though I love their products and innovations, it sadly looks like both Pioneer and Roland follow the same kind of strategy in terms of product lifecycle management.
