Ø Sine

Bitwig Platform

Ø Sine module panel in Bitwig Grid
Ø Sine in Bitwig Grid 6.0.6.

Converts normalized phase into one cycle of a bipolar sine waveform.

What it does

Ø Sine is a sine lookup driven entirely by its phase input. At audio-rate phase it becomes an oscillator waveform; at slow rates it becomes a smooth bipolar modulation curve.

Controls and ports

The wrapper has one phase input and one bipolar waveform output, with no independent pitch or rate control.

Practical uses

  • Feed it a Phasor for the cleanest basic phase-driven oscillator shape.
  • Warp or modulate phase before the module to create related nonlinear waveforms.
  • Use transport phase for smooth cyclic modulation synchronized to the project.

Things to know

  • Frequency and reset behavior come from the upstream phase source.
  • A valid phase cycle is wrapped and interpreted as one complete sine period.
  • The recovered implementation calls Bitwig's optimized sineWF5 helper rather than exposing a literal library sine call.
  • The precise approximation error of that helper is not yet documented.

Technical details

A high-confidence Nitro implementation candidate supports the technical summary, but the visible-module mapping remains inferred.

Conceptually the lookup is out = sin(2π * phase) with Bitwig's phase orientation. The confirmed Nitro body delegates to the internal sineWF5(x) waveform helper, so its exact polynomial or table approximation and boundary handling must be recovered from that helper before claiming bit-exact equivalence.

Open questions

  • Recover or measure the sineWF5 approximation, exact phase orientation, wrap boundary, and non-finite handling.

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.
