Description

Notch turns continuous waveforms into stepped ones. This modulator is based on the ER301 grid quantizer unit, which I've always wanted to have in other formats but have never come across elsewhere. You feed the input any other modulation (or just control from a midi fader etc) and set the number of desired 'notches' in the output from 2 to 16. These notches are placed evenly across the height of the output. With steps set at 2, you will get a low/high (off/on) control, i.e. a square wave. Higher step counts produce more notches, but you will always get minimum and maximum values at the extremes of the input.

Some basic ideas for usage:

- Creating detents in continuous controls, useful for mixing applications where you might want to restrict your possible choices.

- Creating crude presets across a continuous control, useful in performance when you want to reliably catch only a handful of positions across the throw of a dial.

- My favorite usage is to follow this type of modulator with a slew limiter. This way you can snap to given positions on a control, but with smooth interpolation between each position. Consider using Notch in combination with Spaghetti, my slew device.
