Slew Limiter

Rate Knob Sets the slew rate.
Skew Knob Skews the slopes. When centered (double-click), rise and fall time are the same. When turned counterclockwise, rise time becomes shorter. When turned clockwise, fall time becomes shorter.
Reset Input When Reset is triggered, the output immediately jumps to the input voltage.
Main Input Signal that will be slew-limited. Typically a gate, LFO or some kind of envelope.
Lin Output Signal slew-limited with a linear slope.
Exp Output Signal slew-limited with an exponential slope.

Overview ⚓︎

A slew limiter limits the rate of change of its input signal, or, in other words, softens the sharp edges of the signal.

Our take on this unassuming utility module packs a lot of punch. It simulates two fully independant slew-limiting circuits: one linear and one exponential.

The Slew Limiter is very similar to the Glide module. The Slew Limiter is better adapted to LFO or envelope signals, while the Glide module was designed to be used for pitch signals.

Rate ⚓︎

The Rate knob adjusts the slew rate. It displays an approximate value in seconds, but the meaning of this value is different for the Exp and Lin outputs.

Effect of Rate on Exp output

For the Exp output, the value of the Rate knob is the time to reach within 99% of the voltage variation on the input. If the input quickly jumps from 0V to 10V, then the output will be 9.9V after that time.

Effect of Rate on Lin output

For the Lin output, the value of the Rate knob is the time to change the output by 10V. If the voltage on the input jumps from 0V to 1V, it will only take one tenth of the Rate time for the output to reach 1V.

Skew ⚓︎

The Skew knob can make the slew rate faster for either rising or falling slopes.

When Skew is centered (default double-click value), the rate is the same for upwards and downwards slopes.

From the center position, the upwards slope time will become shorter as the knob is turned counterclockwise, and the downwards slope time will become shorter as the knob is turned clockwise.

Reset ⚓︎

When the Reset input is triggered, the output will immediately be set to the input voltage, bypassing the glide algorithm.

This is a one-time event that happens when the input goes from low (0V) to high (10V). Keeping the input high will not disable the glide effect.

This feature may be used to generate very simple pluck envelopes by connecting a trigger signal to both the In and Reset inputs.
