// ADD FADE — a crossfade that blows out additively through the middle:
|
|
// as deck B fades in, its light also pours on top of the mix (mid-fade
|
|
// only), then the transition lands clean on pure B. CURVE bends both the
|
|
// fade law and where the bloom peaks, BOOST sets the bloom's strength,
|
|
// DIP ducks through black just before it.
