Roots

Calculates an integer-degree root from 1 through 9 of the incoming signal.

What it does #

Roots applies the root selected by its Degree parameter. Degree 1 passes the value unchanged, degree 2 is a square root, degree 3 is a cube root, and so forth.

Controls and ports #

Control	Label	Official description
root	Root	Integer degree of the root performed on the incoming signal. So '2' performs a square root, '3' a cube root, and so forth.

Practical uses #

• Use a square root to expand lower values in a unipolar 0-to-1 modulation signal.
• Use a cube root for a gentler polarity-preserving curve; the measured cube root of -8 is -2.
• Pair a root with the matching integer exponent to approximately undo a previous curve operation.

Things to know #

• Degree is restricted to integers from 1 to 9.
• Even roots of negative numbers have no real result; the measured square root of -4 displayed negative infinity.
• Odd roots preserve real negative results; the measured cube root of -8 was -2.

Technical details #

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

The documented contract is y = x^(1/n) with integer degree n ∈ [1, 9]. Bitwig distinguishes parity for negative inputs: the measured even case degree 2, x = -4 displayed -∞, while the odd case degree 3, x = -8 produced the real result -2.

Open questions #

• Measure the remaining Degree values 1 through 9, zero, and near-zero negative radicands.

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.
