Pitch Scaler

Bitwig Platform

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

A two-point linear mapper from a unipolar control signal to a selectable pitch range.

What it does

Pitch Scaler interprets zero as its Low pitch and one as its High pitch, with continuous interpolation between them. It converts generic 0-to-1 control sources into a musically readable pitch span before optional chromatic or scale quantization.

Controls and ports

Control Label Official description
low Low Pitch output when '0' is received at input
high High Pitch output when '1' is received at input
value_help Low and High Pitch Values Defined pitches as readable Bitwig pitch value, meaning zero represents 'C3' (middle C) and each whole number is a semitone

Practical uses

  • Map a phase ramp, envelope, random value, or macro into a defined note register.
  • Place by Semitone, Pitch Quantize, or by Scale after it to turn the continuous range into notes.
  • Reverse Low and High to make increasing input values produce descending pitches.

Things to know

  • Pitch Scaler maps a range but does not itself quantize to notes; fractional input normally produces fractional semitone output.
  • C3 is zero, C4 is +12, and C2 is -12 in the endpoint readouts.
  • Whether inputs below zero or above one extrapolate or clamp is not stated by installed metadata and requires measurement.
  • The Hard Kick pitch 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.

For input x and displayed semitone endpoints L and H, interpolation occurs in readable pitch space as s = L + x*(H-L), then the raw output is out = s/120. Represented frequency is 261.625565*2^(s/12), equivalently 261.625565*2^(10*out). The interpolation model is strong interface-level inference, but no exact Nitro body has been recovered.

Open questions

  • Measure x below 0 and above 1 to distinguish extrapolation from clamping.
  • Verify endpoint ranges, defaults, resolution, reversed ranges, equal endpoints, modulation, and smoothing.
  • Test stereo independence, non-finite values, extreme pitches, 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.
