In the end , isn't it all about the quality of sound, that we produce that counts. It must satisfy us first, and that is where everyone is different. Some like Yamaha, or Korg or Roland even Nord for example.
Then comes how you get it our of that durn box the way you want it to be. If it don't feel right or sound right even smell right; you are not satisfied till you find it.
To me its about more then just sound quallity.. when comparing for example Pa4x to Genos and SD9.. most of us only hear the real differences in a direct comparrison. All 3 sound very good on their own..
Its also about being fun, feeling, and features..
And thats why i will not be really sattisfied till i have that one 88 key instrument with great keybed that combines all features of a Stage piano, synth workstation and arranger in one metal box.(dislike plastic)
I guess i will have to build one myself based on Varranger, Reason, bitwig and VST’s..
