Since you are approaching this as a musician, look at it this way:
The drummer doesn't give a rip about your sax, and you probably have little interest in his kit, either. But there may be some things that you may find interesting or useful, no matter your musical differences. You might end up using the same IEM's, throne, or possibly a light, just because they work for the both of you.
On the flip side, there is a lot more stuff that you do not have in common, like mic's, pads, stands, etc. The same applies to the MIDI controller. It may be aces for you, but the appeal is that it can be modified to fit the needs of other musicians who might care more about features that you haven't made very prominent, and can discard things that they wouldn't ever use. That's what a designer app is all about. Find what you like and incorporate it and declutter the screen from things that you don't.
After all, you wouldn't want the drummer to dictate the tools that you have to use on stage. If you were to lock the design, you are doing exactly what TC-Helicon did that you didn't like - making you use it the exact way that they designed it. The beauty is that you have found a way to do it another way - a way that works better for you - but maybe not optimally for someone else. Why do what TC-Helicon did and force other people to do it only your way? Share it and let others enjoy the ability to use your design as a launching point to their own freedom. You make a better name for yourself doing it that way than TC-H's way!
