Plugin Boutique has published a tutorial video in which Jerry Mateo demonstrates how to mix a kick and bass guitar together in TrackSpacer by Wavesfactory.
Trackspacer is a plugin that creates space in a mix by carving the frequencies that the main track needs into another track in real time.
Similar to a sidechain compressor, but a thousand times more powerful and transparent. It’s considered a secret mixing weapon by many artists, producers and engineers.
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.
Trackspacer is available as a 32/64-bit plugin for Windows and Mac (VST/VST3/AU/RTAS/AAX).
