Ø Sinemod

Uses a sine derived from the input phase to create periodic phase modulation with selectable cycles and depth.

What it does #

Ø Sinemod reads the incoming phase as the position of an internal sine modulator. Cycles chooses how many sine periods occur during one input phase cycle, Depth sets its amplitude, and Add chooses whether the original phase is included with the modulation result.

Controls and ports #

Control	Label	Official description
depth	Depth	Amplitude of the sine modulator signal
cycles	Cycles	Number cycles in the sine modulator signal
add	Add	Adds the input signal to the modulated signal

Practical uses #

• Add sinusoidal phase modulation before an oscillator to generate sidebands and waveform motion.
• Increase Cycles for denser, faster phase ripples within each source cycle.
• Disable Add when the sine-derived phase pattern itself should drive a lookup module.

Things to know #

• This derives modulation from the phase input; it does not run an unrelated free oscillator.
• Depth controls the magnitude of the phase displacement.
• Add changes whether the input phase is part of the result, which substantially changes the traversal.
• Audio-rate phase modulation can generate strong high-frequency content and aliasing.

Technical details #

No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.

A safe behavioral model is m = depth * sin(2π * cycles * phase), followed by either the modulation-only result or phase + m when Add is enabled, with the final value kept in the phase domain. No dedicated Nitro implementation is mapped, so the exact Depth scale, sine polarity, and final wrapping policy remain unconfirmed.

Open questions #

• Measure the exact equation, Depth scale, Cycles quantization, Add-off range, wrapping policy, zero settings, and stereo 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.
