Spectral Blend
Spectral Blend — combines TWO sounds in the frequency domain. Wire a source into A and another into B and pick a Mode: MORPH crossfades A↔B bin-by-bin (a spectral crossfade, not a level mix, so one timbre becomes the other); CROSS speaks A's tone through B's motion; VOCODER makes A speak B's spectral shape (talkbox); UNION composites the louder of each; MASK ducks A where B has energy (a frequency-domain sidechain — carve space for B); CONVOLVE multiplies the two spectra (cross-convolution = convolution reverb generalised — colour A by B). Blend is the A↔B crossfade for Morph, else the dry→wet amount; automate it to dissolve one sound into another. Melody spectral_fx_rt worklet (multi-input).
