I read your post before you deleted it but just wanted to comment. I have submitted presets for inclusion in the factory banks of several synths (not Synthmaster) and the developers used what I considered to be the weakest ones and left what I thought were my best work on the cutting room floor for lack of a better term.
It's all a matter of taste and in the end its the developer's right to choose what they think shows off their synth in the best light, our egos be damned.
I wouldn't take it personally or let it discourage you.
