ALM/Busy Circuits launch Pip Filter & LFO

16/06/2025

Two new compact 4HP modules introduced

ALM/Busy Circuits have just announced the launch of two new Eurorack modules, the Pip Filter and Pip LFO, both of which pack a comprehensive selection of features into just 4HP.

Pip Filter The first of the two new modules is the Pip Filter, a compact 4HP voltage-controlled two-pole resonant low-pass filter equipped with a 'pingable' trigger input and built-in VCA. Filter cutoff can be controlled via both a front-panel control and a pair of CV inputs, once of which includes a built-in attenuverter; resonance is manually controlled, and the module can be pushed into self oscillation. Theres's also a trigger input that allows the filter to be pinged' in order to create percussive, plucked sounds, while a built in VCA allows for independent amplitude control of the filtered signal.

Key Features

Compact filter and VCA in 4HP.

Dual-pole 12dB/Oct low-pass filter with resonance.

Two frequency CV inputs, one with attenuversion and one with rough V/oct tracking.

Manual resonance control going into self-oscillation.

Trigger input for 'pinging' filter.

Normalled VCA input for optional amplitude control.

Skiff-friendly with reverse power protection.

Two-year warranty.

Made in England.

Tech Specs

Size: 4HP.

Power: +12V 25mA / -12V 25mA.

Depth: 32mm (approx).

Pip LFO The second of the new offerings is an all-analogue LFO that features a wide frequency range, voltage control, numerous outputs, a reset input and a VCO mode. The speed of the LFO can be defined by a manual control or voltage control input, and there's a choice of a unipolar square wave output along with both bipolar and unipolar triangle, saw and sine waveform outputs. With the VCO mode activated, the frequency is increased to audio range, and offers V/oct tracking for approximately five octaves.

Key Features

Manual and CV control over LFO frequency.

Frequency range from approximately 0.01Hz to 20kHz+

Square, triangle, saw and sine simultaneous waveform outputs.

Uni and Bipolar outputs.

Audible-frequency VCO mode with V/octave tracking.

LED frequency indication.

External reset/sync input.

Skiff-friendly with reverse power protection.

Two-year warranty.

Made in England.

Tech Specs

Size: 4HP.
