S&H

Captures a CV value on each trigger and holds it

Open in the synth with a demo patch Open Modular

What it does

S&H (sample and hold) is a freeze-frame for a control signal. Something flows continuously into the input, an LFO for instance, and on every event at the Trig input the module snapshots the current value and holds it at the output until the next event. A smooth wave becomes steps in time with the clock; noise becomes random but synchronized values. Slew stretches the transition between steps so the modulation does not click.

Try this

Feed Noise and Clock into Sample & Hold for random values that change in steps.

Ports

in: The CV to capture
trig: Event: take a new value
out: The held value

Parameters

Slew

Try this

Smooth random LFO → S&H In, Clock 1/8 → S&H Trig, S&H Out → Filter Cutoff: the cutoff jumps somewhere new on every beat.
Euclid → S&H Trig and S&H Out → Sampler Pos: the grains read the sample from a new spot on every hit of the rhythm.
Slew 0.3 s turns the steps into gentle slopes; the modulation glides to the value instead of jumping.
