Ø Bend

Curves a phase ramp toward its beginning or end while preserving the cycle boundaries.

What it does #

Ø Bend changes how quickly phase travels through a cycle. Positive and negative Bend values redistribute time toward opposite ends of the ramp, so a downstream oscillator or lookup table reads different regions faster or slower without replacing its stored waveform.

Controls and ports #

The wrapper exposes a phase input, a Bend amount input/control, a Stereo-ize option that applies opposite bend directions to alternating stereo lanes, and a phase output.

Practical uses #

• Place it before a phase-driven oscillator to add harmonics without changing the oscillator table.
• Modulate Bend slowly to animate the timing and tone of a static waveform.
• Enable Stereo-ize for complementary left/right phase curvature.

Things to know #

• Bend changes phase timing rather than directly changing audio amplitude.
• An amount of zero is the identity transform for a valid phase ramp.
• The input is wrapped before the curve is applied, so out-of-range finite values are folded back into one phase cycle.
• Stereo-ize alternates the sign of the Bend amount between internal lanes.

Technical details #

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

The confirmed grid/phase/grid_phase_bend.nitrobin body first computes a = in - floor(in). With Bend amount c, it applies the quadratic warp twice: x = a * (1 + c * (1 - a)), then out = x * (1 + c * (1 - x)). Stereo-ize uses alternating c and -c lane values. The process is stateless and sample-local.

Simple process assignments:

• out = y

Open questions #

• Measure a dense transfer sweep, confirm Stereo-ize lane assignment in the visible module, and test non-finite inputs.

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.
