ALM Busy Circuits PIP LFO

ALM’s Pip LFO is a compact yet versatile all-analog LFO with a wide frequency range and a clever switchable VCO mode. Designed for minimal rack space without sacrificing functionality, Pip LFO delivers classic modulation waveforms—square, triangle, saw, and sine—all available simultaneously via unipolar and bipolar outputs.

Whether you need slow, evolving modulation or want to crank things into audio-rate territory, the Pip LFO is ready. Flip it into VCO mode and it tracks 1V/Oct for about five octaves—perfect for extra voices, drones, or FM duties. A reset input adds further utility for syncing cycles or triggering hard-sync style effects when in oscillator mode.

A dense, practical design that does modulation and sound generation without any menu-diving or complexity.
