Chaos Monster

Chaos Monster

The acid / industrial monosynth that bites back

Some synths are polite. This one isn’t.

Chaos Monster is a monophonic synthesizer built for the sounds that define acid, techno, industrial, EBM and dark electronic music: squelching resonant basslines, hard-sync zaps, wavefolded growls, and feedback that turns a filter into a living, screaming instrument. Open it, pick a patch, hit a key, and you are already in a track.

What makes it different

• The Chaos Loop: an audio-rate feedback path from the output back into the filter, with delay, 0–360° phase rotation, tone and a built-in limiter. It gives you comb and ring textures, self-oscillation, drones and circuit-bent screams, and no ordinary synth has it as a front-panel feature.
• Real acid DNA: an 18 dB/oct diode-ladder filter with a resonance-drive stage, accent envelopes that build up like a TB-303, and true slide (glide without re-triggering).
• Brutal, but under control: four overdrive types (Tanh, Clip, Wavefolder and Diode) with up to 36 dB of drive and bias. The non-linear stages are 4× oversampled to keep the top end clean, and a safety limiter is on by default. Switch it off when you want raw, hot chaos.

The sound engine

• Two hard-sync oscillators (saw / square, pulse width, semitone and fine tuning) plus a sub oscillator (−1 / −2 octaves). The Sync Sweep gives you the classic sync “zap”.
• Two filters: the diode ladder, plus a multimode state-variable filter (LP / BP / HP / Notch). Run them in series or parallel and blend them with the Mix control.
• Envelopes: filter decay, accent, slide and a full amplifier ADSR.
• Pitch-bend and mod wheels: they respond to your MIDI controller and to the mouse. The mod wheel opens the filters as you play.

16-step acid sequencer and arpeggiator

Pitch, accent, slide and gate length on every step. Choose the pattern length, swing and six rates (1/4 to 1/32, including triplets), and sync to your host or run on the internal clock. Hit Random for an instant pentatonic acid line. Hold a key to transpose the pattern, or switch to Arp mode (up / down / up-down / random) and let the pattern supply the rhythm.

351 factory patches in 16 categories

Leads, Bass, Brass, Synths, Pads, Strings, Percussion, Keys, Plucks, Effects, Acid, Arps, Industrial, Chaos, Drones and Basics. A fast patch browser with category column and search helps you find a sound in seconds. Save your own sounds, or load and share patches as files.

Built for the studio

• All controls are standard host parameters, so automation, MIDI learn and undo work in your DAW.
• Built-in oscilloscope and FFT analyzer, so you can see what the filter and feedback are doing.
• Resizable interface (55 %–180 %) with a vintage analogue look: wood cheeks, black plates, chrome knobs.
• Formats: VST3, AU (macOS) and Standalone.

Simple, private, offline activation

No account, no internet connection, no dongle.

1. Click the key icon in the plug-in and copy your Machine ID.
2. Send it to us after your purchase.
3. We send your personal Unlock Key. Paste it in and the plug-in is permanently unlocked on that computer.

Until it is activated, the plug-in runs in Demo mode. It is fully playable, but a short noise burst interrupts the sound about once a minute.
