Math / Other - Signal Mixer
Crossfade function. It blends between the first two signals using the third argument, normally 0.0 to 1.0.
Use moderate values first, then increase modulation depth while listening for clipping, aliasing, or excessive filter resonance.
xfade(saw(X), squa(X), 0.35+0.3*param(2))
xfade() is a mathematical signal mixer, not an envelope or oscillator. Its inputs can be audio signals, control expressions, or both.
