Bonobo runs TB Reelbus on almost everything in his sessions, using the tape emulator's wobble to keep synths from sounding static and lifeless.
The plugin adds width and a touch of saturation, but the real payoff is its tape modulation. That subtle pitch wobble gives flat, sequenced synth parts a human, alive quality.
It's a quick way to add movement to programmed sounds without changing the notes or the arrangement, just the texture underneath them.
