Two filters. Every shape between.
Fifty-eight filter types across two stereo filters — chained, parallel or split — with a full modulation section and a finishing stage of saturation and twenty effects. Works as an effect on any channel, or a synth played from MIDI.
The interesting sounds live in between: a ladder pushed into overload, a vowel that moves, a comb tuned to a note, two band-passes pulling against each other.
Then route, balance, and start over for every new sound
Both filters, the modulation section, the saturation and the effects all sit in one plug-in with one picture of what is happening. The display shows both filter curves over the live spectrum so you see exactly what one is doing to the other.
Two filters. One place. Everything connected.
Both filters run in stereo and share a live spectrum display. Route them in series, in parallel, or split across left and right — then move them with everything the modulation section has.
Twelve families: lowpass and highpass in six slopes each, bandpass, notch and allpass, analogue ladders that self-oscillate and overload, resonators and vowel formants, phasers, combs, EQ shapes, FM and ring modulation, and lo-fi resamplers. Every type is available to both filters at the same time.
Serial 1 > 2 and Serial 2 > 1 run one filter into the other — a highpass into a lowpass becomes a band you shape from both sides, a ladder into a formant becomes a voice with a body. Parallel feeds both from the input and adds them. Split L/R gives each filter its own side.
An oscillator with fifteen shapes, two tempo-synced LFOs with eight shapes, a sixteen-step sequencer and an envelope follower all feed one eight-slot modulation matrix. Anything that moves can move almost anything else — cutoff, resonance, drive, level, pan and more — across both filters at once.
The output spectrum fills the display in real time. Both filter response curves are drawn over it — blue for filter 1, yellow for filter 2 — before modulation. You see where each filter sits; the spectrum shows what it is actually doing to the signal right now.
Twelve saturation types — Soft Clip, Hard Clip, Tube, Presence, Wave Wrap, Wave Shape, Bit Crush and more — placeable before or after the filters. Twenty effects in three families follow: eight delay types, four modulation effects, and seven reverbs from Ambience to Cathedral.
Switch between Effect mode, where the filters process your incoming audio, and Synth mode, where the internal oscillator replaces it — played from MIDI on an instrument track. One licence covers both the effect and the synth version. Forty-two factory presets across five groups get you started straight away.
The download is the full plug-in. Without a licence it runs in demo mode: every twenty seconds the audio briefly mutes for five seconds, then fades back in. Every filter, every parameter, every preset available to try before you decide.
VST3, AU and Standalone. macOS 11 or later, Apple Silicon and Intel. Includes FilterFOLVK (effect) and FilterFOLVK Synth (instrument).

Yes. Download the demo here — it's the full plug-in. Without a licence it mutes briefly every twenty seconds. Every filter, every parameter and every preset is available to try. Purchase unlocks it permanently.
Fifty-eight across twelve families: lowpass and highpass in six slopes each (6 to 48 dB/oct), bandpass, notch and allpass, analogue Moog and Diode ladders, resonators, vowel formants (A, E, I, O, U and Vocal Morph), phasers and combs, EQ shapes (peak, shelf, tilt), FM and ring modulation, and lo-fi resamplers.
FilterFOLVK launches on macOS (11 or later, Apple Silicon and Intel). A Windows version is not planned for the initial release.
No. FilterFOLVK is a separate product with its own licence. Your existing purchases stay exactly as they are.
