-
Cinnamon
A unique-sounding state-variable filter with simultaneous low-pass, band-pass, and high-pass outputs, voltage-controlled cutoff, Drive switch for input overdrive, and Character switches to modify resonance response.
-
Ikarie
Ikarie is a uniquely sculpted, flexible stereo or dual peak filter module. It can continuously transition between lowpass and highpass filtering with a single knob, and packs an envelope follower for the incoming audio signal. Two parallel 12dB/oct state variable filter cores can run in stereo, dual mono, or series (24dB/oct). Includes internal VCA, CV control over panning and resonance, optional input overdrive, and a Beyond output for the spectral difference (twin peak filter).

A-120 24dB Low Pass 1
Voltage controlled 24dB/octave transistor ladder lowpass filter with three CV inputs, manual cutoff frequency control, and resonance adjustable to self-oscillation.
-
A-124 Wasp Filter
Special voltage-controlled multimode filter with a cut-off slope of -12dB/octave, using the peculiar electronic circuitry of the EDP Wasp synthesizer. Abuses digital inverters as analog operational amplifiers. Has band-pass output and combined low/notch/high-pass output. Cannot self-oscillate.
-
SVF 1U
Multimode state-variable filter in Intellijel 1U format with dedicated LP and HP outputs, switchable BP/Notch output, optional +6dB input boost and asymmetric clipping, 1V/Oct PITCH CV input, FM CV input with attenuverter, and self-oscillation capable of generating sine waves from 2Hz to 20kHz.
-
Grainity
Digitally-controlled full-analog Granular + Multimode VCF with two simultaneous filter flows (Granular VCF and Multimode VCF), each with its own output, plus a Mix output blending both. The granular section reshapes filter response on a per-cycle basis to create subharmonics, harmonies, unison, flanging, and formant effects; the multimode section offers LP2, LP4, HP, BP, BR, and IN modes.
-
QPAS
The Quad Peak Animation System (QPAS) is a stereo multimode filter module utilizing four state-variable filter cores, with Low Pass, High Pass, Band Pass, and Smile Pass outputs simultaneously available, a pre-filter stereo exponential VCA, and Radiate controls that spread and animate resonant peaks in stereo.
- Ripples (original)
-
Morpheus
Stereo Morphing Z-Plane Filter with 289 filter Cubes, each composed of up to 8 complex frequency response configurations interpolated in three dimensions (Frequency, Morph, Transform) via real-time CV control.
-
MMF
12dB/octave state variable multi-mode filter in 4HP with simultaneous LP, BP, and HP outputs, voltage-controllable cutoff and resonance, 1V/oct tracking, and a PING input that generates a fast-decay vactrol-like envelope without a vactrol.
-
Stereo Dipole
Quad Multi-Mode VCF featuring two identical dual-peak filter channels with single (POLE) and dual-peak (DIPOLE) outputs per channel, plus a combined quad-peak mono DIPOLE AB output. Each channel has HP/BP/LP mode selection, DRIVE, FREQ, SPREAD, and RESONANCE controls with serial/parallel routing between POLE and DIPOLE stages. Stereo CV inputs allow simultaneous control of all four filter cores.
-
Z2040 4-pole VCF
8HP 4-pole 24dB/oct low-pass VCF with a discrete core modeled on the SSM2040 chip (used in the Prophet 5 Rev 2). Features a configurable audio VCA (input or output), VC resonance, FM input with VC-FM index, and self-oscillation capability as a sine-wave VCO.
-
C4RBN
4/2-pole state-variable filter with input saturation, output wavefolding, simultaneous 2-pole HP/BP/LP outputs, and a switchable 4-pole output (HP/LP/BP). Includes a ping circuit emulating vactrol response and temperature-compensated V/Oct tracking.
-
BELGRAD
Dual peak multimode state variable filter with two analog filter cores, 10 distinct frequency responses, voltage control over resonance and peaks balance, nonlinear feedback and cross-modulation, and adjustable input overdrive. Model of 1976.
