Ø Pulse

Bitwig Platform

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

Converts phase into a bipolar pulse waveform whose negative portion is set by Pulse Width.

What it does

Ø Pulse is a phase lookup, not a self-running oscillator. It reads the position within one phase cycle and returns either side of a bipolar pulse shape; Pulse Width controls how much of the cycle remains negative.

Controls and ports

Control Label Official description
pw Pw Percentage of each cycle that the pulse wave stays negative

Practical uses

  • Drive it with Phasor or another audio-rate phase source to create a pulse oscillator.
  • Use a slow phase ramp to create a two-state bipolar modulation shape.
  • Modulate Pulse Width to animate the duty cycle or create pulse-width-modulation timbres.

Things to know

  • Pulse Width is described as the percentage of each cycle for which the output stays negative.
  • The phase input is wrapped, so successive integer phase cycles address the same shape.
  • Abrupt pulse edges generate strong high-frequency content and can alias at audio rate.
  • The recovered DSP also has a Sharpness input that may be supplied by shared wrapper behavior rather than a visible main control.

Technical details

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

The confirmed Nitro body wraps phase x, clamps PW to 0.01 through 0.99, and evaluates z = (abs(x - 0.5) - 0.5 * PW) * sharpness, followed by out = clamp(z, -1, 1). This places the negative region around the center of the cycle and uses Sharpness to control the transition slope before output limiting.

Open questions

  • Confirm the visible Sharpness source and default, exact boundary samples, and audio-rate anti-aliasing behavior.

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.
