ComfyUI Node

Stem Mixer

Mixes the stems back into one song: gain, mute/solo, compression and muted time ranges per stem (and the residual 'rest'). Empty settings mix neutrally and return the input. No normalisation; Master sets the loudness. The widget shows one strip per stem before the first run too, and a strip marked *save* is written as its own file to output/plenio/stems. Experimental.
