Outputs high logic whenever the first signal is strictly less than the second.

What it does #

Less Than compares the two current samples and returns 1 only while the first is below the second. Equality produces 0.

Practical uses #

• Create a gate for the portion of a signal below a threshold.
• Detect negative values by comparing the signal with zero.
• Select the lower-valued branch of a modulation or audio patch.

Things to know #

• Input order matters: swapping the inputs reverses the comparison.
• Equality is excluded; use Less Than or Equal for an inclusive boundary.
• At audio rate it can turn a smooth waveform into a pulse-like logic signal.

Technical details #

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

Stateless per-sample comparison: out = (a < b) ? 1 : 0. The installed truth table confirms the four binary cases.

Open questions #

• Confirm the runtime policy for NaN operands.

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.
