This short segment from Bitwig's modular feedback tutorial focuses on two specific tools inside The Grid: Pressure In and Modulator Out. The presenter shows how to use polyphonic pressure (via MPE or drum pads with per-note aftertouch) to control feedback intensity in real time, with each held note responding independently to how hard you press.
Modulator Out is the key bridge here. When a parameter inside The Grid has no dedicated modulation input, this device converts any signal into a modulator that can target it. That makes otherwise fixed parameters fully performable.
The practical result is expressive, per-note feedback control: hold a chord, then selectively push pressure into the low notes to bring in instability while the high notes stay clean. It is a technique that turns a static patch into something you can actually perform.
