Bitwig's Reverb device includes a Tank FX slot, a dedicated insert point inside the reverb's feedback loop where you can place any effect, including third-party VST plugins. This bit shows how placing a pitch shifter there causes every reverberation to shift in pitch relative to the last, building shimmering octave-up or sub-harmonic textures over time.
Adjusting the pitch interval changes the character dramatically: a fifth gives a stacked, harmonic bloom, while shifting down an octave adds weight and reinforcement. Anything placed in the Tank FX slot is saved as part of the device preset, making this a practical way to bake complex, evolving reverb textures directly into a sound design workflow.
