Erica Synths Pico LFO/S&H
Analogue LFO and Sample and Hold in 3HP
3 HP Eurorack module
Pico LFO/S&H is a fully analogue modulation source combining an LFO with triangle and square wave outputs alongside a highly stable Sample and Hold circuit. It injects controlled randomness and rhythmic modulation into a modular patch, making it ideal for adding life to static patches or generating unpredictable voltage sequences. The S&H circuit uses the AS1100CK2 IC for minimal droop and accurate voltage tracking.
