The acid engine
The classic acid voice: a squelchy resonant filter, accent and slide. The Source panel adds saw, square or your own wavetable, with Morph, Sub and Tune.
Saw, square or your own wavetableThree engines in one synth: the acid engine, a classic 70s ladder and FANG. Lines that talk, a low end that holds still.
$79 now, $119 after the launch. Launch price for the first 200 buyers.
Presets by OXIV and friends, the same line on every one. Straight out of the plugin, no layers. One plays at a time.
We kept the soul of the 303 and built what it never had: a second voice, a low end that holds still, and a sequencer that thinks in key.
Three engines, a smart sequencer and a whole modulation system. Flip through the cards.

The classic acid voice: a squelchy resonant filter, accent and slide. The Source panel adds saw, square or your own wavetable, with Morph, Sub and Tune.
Saw, square or your own wavetable
A fat four-pole ladder engine with three oscillators, glide and drift, and its own filter and amp envelopes.
3 oscillators
A wavetable bass engine for psytrance, techno and mid-bass growls. Two wavetable oscillators, warp, sub, noise, knock, Punch and multiband post drive. Load your own wavetables.
30 filter types, 6 built-in tables
The second oscillator, unison, envelopes, knock, noise and the filter, all in one window. Up to four unison voices, and the lows stay mono.
Up to 4 unison voices, mono lows
Tone adds harmonics above a split, so the low end stays clean. Bass Mode steadies the lows with Tight, Sub, Weight, Duck and mono below a frequency. Then a rack of distortion pedals.
10 distortion types, 3 Clarity modes
64 steps with accent, slide and length lanes. The smart AI sequencer suggests lines in your style and scale, Variations turns a line into musical variations, and a library of lines is built in.
64 steps, 6 styles, 17 scales, 146 built-in lines
An arpeggiator with eight note orders, a musical random walk among them, and six lanes of different lengths. Change chords and it keeps going. Print writes it into the sequencer.
8 orders, 6 lanes, up to 16 steps a lane
Draw your own shapes, or pick sample and hold, sample and glide or drunk random. Sync to the beat or run free. Drag one onto any knob and a coloured ring shows it moving.
4 LFOs, 9 shapes, 8 destinations each
A smart sample and hold, locked to the steps of the line. It remembers what it did, it can lock a step, and its moves land in time with the music.
Step-locked
Delay, attack, hold, decay, sustain and release, with a curve you can bend on every segment. Drag one onto a knob, just like the LFOs.
3 envelopes
Every modulation connection on one page: amount, one way or both ways, curve, an aux source like velocity or the mod wheel, and live meters. Or set the depth by dragging the ring around a knob.
56 connection slots
Chorus, phaser and flanger, a tape-style echo, and the Space reverb: Plate, Hall, Spring and Cosmic, with ducking, synced pre-delay feedback and Freeze.
4 reverb types, oversampling up to 8xA circuit-level acid engine, tuned against 400 notes recorded from real vintage hardware. Six calibrated units, from the clean factory voice to a growling custom box.
Switch to a classic 70s ladder voice: three oscillators, a hot mixer and a 24 dB filter that sings. Your pattern, effects and modulation stay.

Bass Mode fixes the low end the way a producer would. Every note at the same level, the boom tamed. Magic evens the whole line out; the 2nd Harmonic adds the octave for phones, or takes it away for the club.
Off by default. Off leaves the sound untouched.
Learned from real psy, acid and techno lines. Six styles, 17 scales, four ideas at a time, and every note stays in key. Drag the line straight into your DAW as MIDI.
FANG now has 30 filter types, 10 of them new. Start with the band-passes, the squelch techno and psy producers reach for. The same line on each, the cutoff sweeping slowly.


For when you want to know exactly what is inside. Tap a heading to open it.
Harmonics keep the low end clean, and Clarity cuts through the mix.
The new Stereoizer in the output adds width that never touches the mono sum. The kick and the sub stay in the centre, where the club needs them.
Cleaner everywhere: 4x oversampling on the output, and anti-aliased folding and overdrive.


Two minutes, sound on. Every sound is Acidvore.
On a Mac also AU, so it runs in Logic Pro.
