J0()

Category

Math / Waveshaping / Oscillator

Description

Bessel function of the first kind, order 0. It can be used as an oscillator directly with X, or as a special FM-like waveshaper when its input is another oscillator.

Arguments

• value: input value, often an oscillator or modulation signal

Typical Values

Use J0(X) for a playable oscillator. Try values around -4.0 to 4.0 for waveshaping another signal. Larger inputs can create stronger sideband-like motion.

Example

J0(X)

Secondary Example

J0(2.0*sin(X))

Notes

For pitched oscillator functions, X already contains the current MIDI note pitch and transpose information. Prefer saw(X), sin(X), or pwm(X, 0.4) unless you intentionally want an octave or ratio shift such as 0.5*X or 2*X.
