The start of my Technic days, Kn2000, third party styles were hard to find --- and if you were lucky to find one they were not very good. We learned to tweak the on- board styles; which were pretty good. I still believe that is the best way to go.
You pay $1,200 to $4,500 for a keyboard, why not use or tweak the great styles you paid for?
