Field Effect node: controls, inputs and a free patch

Field Effect

Runs a Field kernel once per audio sample as a custom effect you write yourself — declare a bit of state for a delay line or filter memory, declare a param for an automatic modulatable knob, and write the DSP math directly instead of hunting for the right built-in. See Chapter Twenty for the Field language itself.

What it does

Field Effect is an audio effect: it changes the sound that flows through it. It takes audio in and gives audio out.

Try it

Write a simple one-pole low-pass in a few lines and compare it against the built-in Audio Filter.
