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

Turns phase into a unipolar cosine-style window that rises from zero, peaks midway, and returns to zero.

What it does

Ø Window provides a smooth 0-to-1-to-0 shape over one phase cycle. It is useful whenever a cyclic signal needs to be faded in and out without the sharp endpoints of a gate or linear segment.

Controls and ports

The wrapper has one phase input and one unipolar window output, with no independent timing control.

Practical uses

  • Multiply audio by the output to window a grain or crossfade a loop segment.
  • Use it as a smooth unipolar envelope driven by a one-shot or repeating phase ramp.
  • Combine phase-shifted copies to build overlapping windows for granular or overlap-add patches.

Things to know

  • Unlike Ø Sine, the useful output stays unipolar and reaches zero at both cycle ends.
  • The peak occurs around the middle of the phase cycle.
  • Timing, repetition, and reset behavior come entirely from the input phase.
  • The dedicated Nitro module calls a shared cosine-window helper whose exact formula still needs bit-exact confirmation.

Technical details

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

The confirmed body is out = cosineWindow(x). Its visible contract is the familiar raised-cosine window, conceptually 0.5 - 0.5*cos(2πx) for one wrapped cycle: zero at the endpoints and one at the midpoint. The shared helper must be recovered or measured before treating that conceptual formula as bit-exact.

Open questions

  • Confirm the exact helper formula, endpoint samples, wrapping outside 0 to 1, and non-finite behavior.

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.
