Value Scaler

Bitwig Platform

Value Scaler module panel in Bitwig Grid
Value Scaler in Bitwig Grid 6.0.6.

A range mapper that translates a nominally unipolar input between two percentage-valued endpoints.

What it does

Value Scaler converts a 0-to-1 control signal into a new numerical range. Low is emitted at input 0 and High at input 1, with intermediate inputs producing intermediate values; a Bipolar option changes how the source range is interpreted.

Controls and ports

Control Label Official description
low Low Value output (set as percentage) when '0' is received at input
high High Value output (set as percentage) when '1' is received at input
bipolar Bipolar Value output (set as percentage) when '1' is received at input

Practical uses

  • Map one LFO, envelope, or macro into the exact range expected by another module.
  • Reverse a control by setting Low above High.
  • Translate a normalized sequencer lane into an index, modulation depth, frequency-related control, or custom numerical interval.

Things to know

  • Without Bipolar, the nominal source range is 0 to 1.
  • A standard unipolar mapping is linear interpolation between Low and High, but exact clamping outside the source range is unverified.
  • The installed description for the Bipolar control is duplicated and does not explain its precise endpoint convention.
  • The automatic grid/pitch/grid_scale_steps candidate is unrelated and has been rejected.

Technical details

No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.

The nominal unipolar model is out=low+(high-low)*x. A conventional Bipolar mode would first convert x from -1..1 to t=(x+1)/2, then use the same interpolation, but Bitwig's exact Bipolar convention has not been recovered and is not asserted as fact. No dedicated Nitro body has been identified.

Open questions

  • Measure unipolar endpoints, midpoint, reversed/equal ranges, and inputs below 0 or above 1.
  • Recover the Bipolar mode exactly at -1, -0.5, 0, 0.5, and 1.
  • Test stereo input handling, modulation smoothing, precision, non-finite values, and voice scope.

Version and sources

Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
