masterfader - why from -100% to 0% to +100% ?

[rohaantje]

hi,

I've a question about the masterfaders.
Why are those faders from -100%to 0 to 100%??

When i use the masterfaders. The part of 0 till 100% does nothing.

i dont see reason why!

Like this, you can set your dimmers for instance to dmx level 127 (50%), and then the master fader can change the level from 0 to 255 (100%).
