How Is Doorway Used?

The basic soft key function is:
((INPUT - THRESHOLD) * GAIN) + 0.5V = KEY (UNCLIPPED)

Then the outline function:
1.0V - ABS(1.0V - KEY) = OUTLINE (UNCLIPPED)

Then black/white clipping:
IF(KEY > 1.0V): KEY = 1.0V
IF(KEY < 0V): KEY = 0V

Then fading:
(FG * KEY) + (BG * (1.0V - KEY)) = OUT
