The Bitwig team walks through how to use an LFO as a control signal for pitch modulation inside The Grid, showing what happens as the attenuator opens from zero to fully open. A key detail emerges when the attenuator is fully open: the incoming signal is no longer just a modulation offset but is treated as the absolute pitch value, which changes how you think about routing any control signal into pitch.
From there, the Pitch Scaler module enters as the practical solution. It assumes a zero-to-one input and maps it to a defined pitch range, letting you set both the floor and ceiling of the pitch movement instead of relying on the raw attenuator range. This pairs naturally with keyboard tracking, since all pitch signals on the pitch bus add together, meaning Pitch Scaler output, tracking, detune, and any other source all stack as expected.
