KOMBINAT4 is Audio Damage's fourth-generation flagship distortion. Take any sound, split it into up to eight frequency bands, and assign one of 38 distortion engines to each band. Or flip to Serial mode and chain those eight engines end-to-end for stacked, cascading mayhem. THIRTY-EIGHT DISTORTION ENGINES The complete roster from Kombinat Tri returns: Fuzz, Saturate, Distort, Clip, Warp, Degrade, Ring Mod, X Noise, Octaver, Wavy, Rectify, Tube Clip, and the famously unhinged Nerd Rage. Joining them is the entire engine set from our Grind distortion: Tanh, Asym Tanh, Overdrive, Polynomial, Linear Distort, Sine Drive, Var Hard Clip, Gloubi Boulga, MXR, Soft Clip, and Cubic NLD. Plus thirteen brand-new algorithms built specifically for Kombinat4: Wavefold, Chebyshev, Bitwise, Slew Limit, Comparator, Diode Clip, Feedback FM, Fractal, Dropout, Shapeshift, Phase Distortion, Stutter, and Erosion. Every engine has up to three custom-labeled controls plus per-band gain and solo. Pick a different engine for each band and design distortion tones that simply weren't available before. EIGHT BANDS, TWO MODES In Multiband mode, the input is split by Linkwitz-Riley crossovers into up to eight parallel bands. Each band gets its own engine and gain stage, and everything recombines at the output. Drop to two bands for classic low/high splits, push to eight for full-spectrum surgical distortion design, and solo any band to dial it in cleanly. In Serial mode, those same eight slots become a chain — every engine processes the full-bandwidth signal in turn, for layered drive structures impossible to achieve with a single algorithm. OUTPUT SECTION A dedicated output filter with twelve types: 2-pole and 4-pole low-pass, high-pass, and band-pass shapes, a notch, three OTA-style filters, a 914-style ladder bandpass, our Filterpod, and bypass. Built-in Rough Rider compressor at the output with sidechain HPF and external sidechain input. Global feedback path with attack and decay envelope for self-oscillating screams and slow-blooming sustain. Optional AGC for level-matched A/B comparisons across heavy distortion settings. DC blocker. 2x and 4x oversampling for clean high-frequency content. PRESETS AND WORKFLOW Factory preset library covering subtle saturation, mix-bus enhancement, mid-range fattening, lead guitar tones, low-end mangling, full-on industrial destruction, and everything in between. Folder-based user preset browser with favorites and import/export of single presets or full folders as ZIP. XML preset compatibility with the desktop edition — your iOS presets work in your DAW and vice versa. AUv3 plugin for iOS hosts including GarageBand, Logic Pro for iPad, AUM, Cubasis, Loopy Pro, Audiobus, drambo, BeatMaker 3, and others. Standalone app included. Tooltips on every control. Animated band display with realtime spectrum overlay. No DRM, no account, no online activation.

bitcrust is a polyphonic synthesizer built around a SID-style voice architecture: three oscillators per voice, up to twelve voices, with ring mod, hard sync, and the pulse-width behaviour that defined a generation of 8-bit sound. The DSP is an in-house, clean-room implementation written from the public MOS 6581 register map and general DSP literature. It's not an emulator port, so bitcrust sounds SID-adjacent without inheriting the license constraints that keep most SID-inspired tools off the major app stores. Sonically it sits between a chip synth and a modern subtractive. The voice core still does gritty arp basses, zap leads and 8-bit percussion, but the architecture around it (three LFOs, a per-voice mod envelope, an 8-slot modulation matrix, and a 6-slot post-SID FX rack with drive, bitcrusher, tempo-synced delay, chorus, reverb, compressor and limiter) pushes it into pad, keys and texture territory. WHAT THIS PURCHASE INCLUDES Universal Purchase: one price buys the Mac app plus the iPad version (Standalone and AUv3). On the Mac, the App Store build is the Standalone app only. No AU, no VST3: the Mac App Store doesn't distribute plugin formats. AU and VST3 versions are available separately; details at anode-labs.com/bitcrust. The iPad build is a co-equal target, not a downscale. The full 179-preset factory library, all 14 themes, and the complete mod matrix and FX rack ship on both platforms. • Voice core: 12-voice polyphony, 3 oscillators per voice, SID-style triangle / saw / pulse / noise with hard sync and ring mod, per-VCO ADSR • Filter: global VCF (LP / BP / HP) with live curve, selectable 6581 / 8580 chip model, Vintage vs. Modern oscillator mode • Modulation: 3 global LFOs (7 shapes, host-sync or Hz), per-voice mod envelope, 8-slot matrix, MIDI sources (velocity, poly AT, channel AT, mod wheel, pitch bend) • FX rack: 6 slots, drag-to-reorder, per-slot bypass / mix; Drive (5 modes), Bitcrusher, Delay (tempo-sync), Chorus, Reverb, Compressor, Limiter. Every FX parameter is a modulation destination. • MIDI: 16-step sequencer, arpeggiator (Up / Down / UpDown / Random, 6 rate divisions, octave range), MIDI Learn on every knob, note Hold • Presets: 179 factory patches across 10 groups, full-metadata save (author, description, tags), Preset Preview audition without committing, A/B snapshot compare, XML import / export • UI: 6-tab navigation, 14 themes with optional phosphor / CRT overlays, monitor strip (oscilloscope, vectorscope, FFT spectrum, 3D spectrogram, stereo field), QWERTY note typing from any tab Mac: Standalone app, universal binary (Apple Silicon + Intel), macOS 12 (Monterey) or later. iPad: AUv3 extension plus a Standalone for headphone jamming. In-DAW use on iPad needs an AUv3 host (GarageBand, Logic Pro for iPad, AUM, Cubasis and so on).
