Octaver

Bitwig Platform

Octaver module panel in Bitwig Grid
Octaver in Bitwig Grid 6.0.6.

A discrete pitch transposer whose Amount moves the incoming pitch by whole octaves.

What it does

Octaver adds or subtracts an integer number of octaves while preserving the note's pitch class. It is a quicker and safer choice than a free semitone control when a signal should move only by 12-semitone intervals.

Controls and ports

Control Label Official description
amount Amount Pitch detune options by octave:

Practical uses

  • Create a bass branch one or two octaves below a shared melody pitch.
  • Duplicate an oscillator layer at an octave without risking a mistuned semitone value.
  • Apply an octave change to only one stereo lane for a deliberately split voicing.

Things to know

  • Octaver processes pitch control signals; it does not perform time-domain octave shifting on an already audible waveform.
  • An octave is exactly 12 semitones and a 2:1 frequency ratio, so the pitch class is unchanged.
  • Stereo-ness is described by installed metadata, but the exact option labels and handling of mono-to-stereo expansion still require a UI check.
  • No dedicated Nitro wrapper has been identified; this simple operation may be compiled directly into the Grid graph.

Technical details

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

For octave selection n, the raw-cable equation is out = in + 0.1*n, because one octave occupies 0.1 in Bitwig's pitch signal. Equivalently, the represented frequency is multiplied by 2^n. This is functional inference rather than recovered Nitro implementation evidence.

Open questions

  • Record every Amount option, its default, and whether typed or modulated intermediate values are possible.
  • Verify all Stereo-ness modes with independent left/right constants and a mono cable.
  • Check modulation smoothing, range boundaries, non-finite inputs, 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.
