Actually, if you are a piano player, weighted action isn't an issue as far as speed is concerned, for sounds like flutes, synths, guitars...piano players can play extremely fast on a weighted action instrument, or concert and jazz pianists would prefer semi-weighted keys.

In actuality, and in my own experience, organ is the only instrument a little more difficult to play on weighted keys...and that's if you are into playing smears, and slides...fast repeated notes aren't a problem for a piano player (who has kept his/her chops up), especially with today's actions having the third sensor which allows this to happen quite easily.

Most keyboardists in a band are primarily piano players, hence the need for a decent weighted action.

Generally, these players rely on a second keyboard for organ...in fact, especially for organ....I don't know too many keyboardists who would prefer a semi-weighted keyboard as their main axe, unless they aren't primarily piano players. Most, if not all, the players I see in groups, use TWO keyboards.

To answer your concern, the idea of 76 weighted is to allow the instrument to fit in the back seat of a compact car, and still allow the player his/her preferred weighted keybed.
