// ADD INVERT — deck B's negative pours light into deck A: result =
|
|
// a+(1-b), so B's SHADOWS add light and B's highlights add nothing — the
|
|
// inverse of the additive mix at 109. GAIN sets the pour's strength,
|
|
// CURVE bends the fader response, KEY narrows the pour to B's own
|
|
// shadows only.
