Triangle

Bitwig Platform

Triangle module panel in Bitwig Grid
Triangle in Bitwig Grid 6.0.6.

A pitch-tracked triangle oscillator with phase Skew and Fold controls for asymmetric and repeated linear shapes.

What it does

Triangle generates a piecewise-linear rise and fall. Skew moves the peak away from the center toward a ramp-like shape, while Fold adds repeated turns inside one root cycle for brighter harmonic results.

Controls and ports

Control Label Official description
skew Skew Tilts the waveshape from a traditional triangle toward a sawtooth or ramp
fold Fold Wraps the waveshape back around, creating additional cycles

Practical uses

  • Use the centered, unfolded shape for a mellow source richer than sine but softer than saw.
  • Move Skew toward either edge for asymmetric ramps and animated PWM-like motion.
  • Increase Fold for additional corners and harmonics without changing the root pitch.

Things to know

  • Skew changes where the waveform turns; Fold changes how many turns occur within the root cycle.
  • The triangle is continuous at its ordinary wrap, but its slope corners still contain harmonics.
  • The internal skew point is clamped away from exact 0 and 1.
  • For external-only phase control, set Ratio to 0:1 and Phase In amount to 100 percent; otherwise the patched phase is added to internal phase.

Technical details

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

The mapped grid_tri4 implementation first creates the same clamped, piecewise phase path used by the Sine oscillator. It maps that path through a Fold multiplier, then evaluates a periodic absolute-value triangle expression. Pitch, ratio, reset, phase modulation, and opposite stereo detune are calculated in the shared four-times-resolution oscillator framework.

Open questions

  • Measure visible Skew/Fold scaling, exact waveform orientation, and the value at every fold boundary.
  • Compare high-frequency spectra with the ADAA triangle used by Union and Sub.
