≠

Outputs high logic while two signals differ under the selected approximate or exact comparison mode.

What it does #

The Not Equal comparator is the inverse form of Equals. Normal mode ignores a small difference around equality, while Exact Mismatches Only reacts to any non-identical floating-point value.

Controls and ports #

Control	Label	Official description
exact	Exact Mismatches Only [toggle]	Requires the signals to be non-identical floating-point values, which may prove too stringent when working with two moving signals
table	Truth table	A  B ≠ 0 0 0 0 1 1 1 0 1 1 1 0

Practical uses #

• Detect that a state, index, or held value has changed from a reference.
• Open a processing branch whenever two control sources disagree.
• Pair it with Equals to create complementary routing conditions.

Things to know #

• Input order does not matter for equality or inequality.
• Exact mode can chatter on moving signals because tiny numerical differences count as mismatches.
• The approximate tolerance is shared conceptually with Equals but has not yet been measured.

Technical details #

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

For each sample the output is 1 when the selected mismatch predicate is true and 0 otherwise. Exact mode uses a != b; normal mode is the logical complement of Bitwig's undocumented approximate-equality test. The binary truth table is XNOR's complement: equal inputs produce 0 and different inputs produce 1.

Open questions #

• Measure the approximate-mode tolerance and confirm it is the exact logical complement of Equals for all 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.
