Exp

Bitwig Platform

Exp module panel in Bitwig Grid
Exp in Bitwig Grid 6.0.6.

Raises the selected base—2, e, or 10—to the incoming signal value.

What it does

Exp treats the input as an exponent. The Base setting selects 2^x, e^x, or 10^x; when the input is not connected, Bitwig documents a default input value of +1.

Note: When no signal is connected, a value of '+1.0' is used.

Practical uses

  • Turn a linear ramp into an exponential curve.
  • Use base 2 for octave-style ratios, base e for natural exponential relationships, or base 10 for decimal decades.
  • Pair Exp with Log using the same base to encode and decode positive values.

Things to know

  • Every selected base is positive, so the output is positive for every finite real input.
  • An input of zero outputs 1 for all three bases.
  • Large positive inputs grow rapidly and can overflow; large negative inputs approach zero.

Technical details

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

Officially defined modes: y = 2^x, y = e^x, or y = 10^x. With no cable connected, x = 1, so the output equals the selected base. The current atlas has no confirmed dedicated implementation for the visible module.

Open questions

  • Measure the finite overflow and underflow thresholds used by the Grid runtime.

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.
