Crossfader

Crossfader editor

A stereo crossfade between two sources on one control.

Inlets
Audio4
Outlets
Audio2

Inlets 1-2 are side A and inlets 3-4 are side B. Fade all the way down passes A, all the way up passes B, and anywhere between blends the two under the law that Curve chooses. Cord two Deck organisms, two loops, or a dry and a processed copy of one signal into it, and cord the outlet on to a Mixer or SoundOut. Match the two sides with TrimA and TrimB before touching Curve: a fade that lurches is usually two sources at different levels rather than the wrong law. Fade can also drive other parameters through Parameter Control, so one sweep can open a filter as it crosses.

Parameters

MasterGainOutput level after the fade and the trims.
TrimALevel of side A before the fade, so the two sources can be matched first.
TrimBThe same for side B.
FadeThe crossfade position. Down is A, up is B.
CurveThe fade law. Zero is a straight line, right for a dry and a processed copy of one sound; about two thirds is constant power, right for two unrelated sources; one is a fast cut where a small move near either end swaps the sound outright.
CutAHeld, the mix jumps to side A whatever Fade says, and returns to Fade on release. Holding A and B together parks the fade at its middle.
CutBThe same for side B.
CutTimeHow long a cut takes to land, in milliseconds. Zero snaps; a few milliseconds takes the click out of a sustained bass.

Recipe

Two-deck blendCord one Deck into inlets 1-2 and another into 3-4, set Curve to about 0.67, and adjust TrimA and TrimB until each deck reads the same on the Mixer meter with Fade at either end. Map CutA and CutB to two pads and set CutTime to about 5 to chop the incoming track over the outgoing one without clicks.
