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. ## Key features - Up to eight frequency bands - 38 distinct distortion engines - Multiband and serial processing modes - Advanced output filter section - Built-in compressor with sidechain - Global feedback path with envelope - AUv3 plugin and standalone app ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/kombinat4/id6761697917/reviews.md ### 5/5 — Awesome! *2026-06-25* This is by far the best distortion audio effects app ever.Keep up the good work. ### 3/5 — Has potential *2026-06-23* The plug-in is not transparent (tested in Drambo) it lowers the output even when everything is bypassed the signal sounds degraded even when everything is bypassed including the compressor… very odd behaviour ### 4/5 — ギターのエフェクトとしても面白いけど *2026-05-28* 標準サイズの iPad ですがツマミ類が小さすぎて使いにくいです。 ## Frequently asked questions about Kombinat4 ### What is Kombinat4?

Lock buttons added next to AGC, Bypass, and DC Block. Engage a lock to keep that setting unchanged when loading presets. Plugin now reports oversampling latency to the host so DAW delay compensation keeps parallel and sidechain routing in phase when 2x or 4x oversampling is active. iOS Only: two-finger crossover dragging on the band display. Grab and move two crossovers at once. NaN protection added to output stage. ### 4.0.2 — 2026-04-28 No release notes. ## More apps by Audio Damage, Inc. - [Grind Distortion](https://appshunter.io/ios/app/grind-distortion/id1249816007) - [Eos 2](https://appshunter.io/ios/app/eos-2/id1252122327) - [Dubstation 2](https://appshunter.io/ios/app/dubstation-2/id1253069666) - [Replicant 2](https://appshunter.io/ios/app/replicant-2/id1261900553) - [Pumphouse](https://appshunter.io/ios/app/pumphouse/id1270238019) - [Axon 2](https://appshunter.io/ios/app/axon-2/id1289090729) All apps by Audio Damage, Inc.: https://appshunter.io/developer/1248448317 ## Related topics [squashit multiband distortion](https://appshunter.io/ios/topics/squashit-multiband-distortion) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
