I think that the use of primary and secondary colors is what makes many people refer to the GUI unfavorably. In our culture you are likely to see mainly primary colors in kindergartens and day care facilities. Whether or not we consciously understand our reaction to visual cues we associate with small kids, the association evokes a reaction.

When I hear people make comments like "looks like a toy" I believe this is exactly the reason.

That theory would be easy to test. If THEMES were available, and some of them were monochromatic or even metallic, it would be interesting to see how many people opted for the primary color themes and how many opted for the more sedate schemes.

MY preferred theme would be a brushed aluminum look with a high-end audio system styling, simulated LED status boxes etc.

(I can see an aftermarket for BIAB theme graphic sets.)



My favorite example of an advanced GUI in an audio app is FLStudio. The app's approach to creating music is very different than BIAB's, but the modularity of design is outstanding in my opinion...

The design and programming principles should be transportable.
