This combinator allows you to split audio signal in 3 bands : a low band with the low part (in volume) of audio, a high band with the high part (in volume, so the louder part), and a mid band that contains the rest of signal.

Low rotary drives the low level splitter. If volume is over this level it will be cut from signal.

High rotary drives the high level splitter. If volume is under this level, it will be cut from signal.

Smooth rotary drives the transient split (from 0ms to 2000ms). At 0ms crack will certainly occur.

Attack rotary drives the dynamic attack of the virtual compressor analysis.

You can solo low, mid or high band with buttons.

You can set a long release (500ms)  to the virtual compressor analysis.

Of course you can enter combinator programmer to change things.
