Trackspacer from Wavesfactory

Hey everybody, I was reviewing the courses on the multi band side chain compression and remembered that I have a plugin called Trackspacer, from Wavesfactory which proposes a different approach about sidechaining.

“Trackspacer features a 32 band EQ that reacts to the incoming sidechain signal. It analyses the spectrum of the sidechain and applies a reversed EQ curve to another track. That way you are creating space for a certain track by cutting the exact frequencies that it needs in realtime to another track.”

What do you think about this ?? compared to the usual way to do it with a multi band compressor
