# Kaona Instruments — Fractaos - [Manual PDF](../../manuals/DocFractaosEN-V1.5.pdf) --- [Fractaos Manual PDF](#) # Creative patch ideas for **Kaona Fractaos** Fractaos is not just “a polyphonic oscillator.” It’s really a **4-voice fractal sound engine** with: - 8 real-time oscillators in 4 driver/follower pairs - per-voice ADSR and fractal filter - CV over key timbral axes - polyphony via MIDI or 4x trig + 4x 1V/oct - drone mode - multitimbral preset-per-voice mode - geometric, texture, and drum fractal models - a special primitive/LFO/FM architecture That means it works especially well when treated as one of these: 1. **A polyphonic voice block** 2. **A drone orchestra** 3. **A timbral percussion generator** 4. **A multitimbral digital ensemble** 5. **A modulation destination for slow, coordinated CV ecosystems** Below are practical and creative ways I’d use it in a Eurorack system. --- ## First: what Fractaos seems to want around it Because Fractaos already contains so much synthesis internally, the most useful companion modules are less “another oscillator” and more: - **polyphonic CV/gate sources** - **MIDI-to-CV / polyphonic sequencers** - **macro modulation sources** - **VCAs / mixers / stereo processors** - **character filters / resonators / wavefolders** - **granular / delay / reverb** - **performance controllers** - **clocked modulation / random** - **quadraphonic or polyphonic utility modules** It appears especially strong when you modulate: - Texture - Morph - Spread - Pitch - Chaos / Primitive Chaos - Speed / Amount Depth and Primitive Depth are stepped and not CV controllable, so those are better treated like “structural scene changes” set by hand or preset. --- # Core strengths to exploit ## 1. Polyphonic fractal timbre with external sequencing Fractaos has 4 separate trig inputs and 4 separate 1V/oct inputs. That opens up **true modular polyphony** without requiring MIDI. ### Pair it with: - **Quad sequencers / polyphonic sequencers** - Winter Modular Eloquencer with expander - Frap Tools USTA - Intellijel Metropolix with supporting utilities - Five12 Vector Sequencer - OXI One via MIDI or CV - **4-channel quantizers** - Intellijel Scales + utilities - Shakmat Bard Quartet - ADDAC quantizer options - **4-channel gate generators / trigger routers** - Mutable Grids-style trigger generators - ALM Pamela’s Pro Workout - vpme Euclidean Circles - Steppy / Varigate style modules ### Creative result: Use Fractaos as a **polyphonic “ensemble oscillator”** where each voice gets slightly different pitch rhythm and trigger phrasing. Since each voice has its own oscillator pair and filter, even simple note sets can bloom into dense harmony. **Patch idea:** Send four related but non-identical pitch lines into the 1V/oct inputs. Use a shared slow CV into Morph and Texture. This creates the impression of a living chamber ensemble rather than 4 identical voices. --- ## 2. Drone machine with harmonic spread Drone mode is one of the most unique features here. In Drone, all 8 oscillators run continuously, and Spread becomes either: - near-unison cluster - progressive octave spreading - or one of **13 chord / microtuning maps** This is huge. ### Pair it with: - **Slow modulation generators** - Make Noise Maths - Xaoc Batumi - Frap Tools Falistri - Joranalogue Orbit 3 / Contour 1 - **Random / chaotic CV** - Make Noise Wogglebug - SSF Ultra-Random Analog - Mutable Marbles - Chaos modules like NLC Triple Sloths - **Stereo ambience** - Mimeophon - Magneto - XAOC Timiszoara - Strymon Starlab - Desmodus Versio - Data Bender for digital fracture - **Resonators / spectral processors** - Mutable Rings (as processor/exciter destination) - 4ms Spectral Multiband Resonator - Xaoc Koszalin / Minsk style stereo processing - fixed filter banks ### Creative result: Fractaos becomes a **self-contained generative drone orchestra**. The chorded Spread zone is especially good for long-form harmonic evolution. **Patch idea:** - Enable Drone mode - Set a texture fractal like Cloud, Cluster, or Ensemble - Send ultra-slow CV to Texture and Chaos - Send stepped random CV to Spread, attenuated so it glides between chord zones - Run stereo outs into a long feedback delay and reverb This gives shifting harmonic weather rather than a static drone. --- ## 3. Multitimbral “4-module-in-1” setup MULTI mode is very powerful: each voice can load a different preset and respond on separate MIDI channels. This means Fractaos can act like: - voice 1 = bass - voice 2 = pad - voice 3 = percussion - voice 4 = lead ### Pair it with: - **MIDI sequencers / grooveboxes** - Elektron Digitakt / Syntakt - Squarp Hapax - OXI One - Cirklon - Deluge - Keystep Pro - **MIDI controllers with aftertouch** - Osmose - Hydrasynth - Keystep 37 / 49 / Pro - expressive MPE-adjacent controllers if channel pressure is usable - **Performance mixer** - WMD Performance Mixer - Toppobrillo / Tex Mix systems - Befaco Hexmix - Happy Nerding PanMix - Cosmotronic mixer utilities ### Creative result: Use Fractaos as a **complete digital multitimbral synth brain inside Eurorack**, then process its stereo output with analog modules. **Patch idea:** Create four presets: - kick/snare percussion fractal - bass using Rule30 or Cantor - shimmering pad using Koch/Julia - unstable lead using Lorenz/Hénon Sequence over separate MIDI channels from Hapax or OXI One. Then route Fractaos through a stereo filter, compressor, and effects chain for an entire track voice in one module. --- # Excellent companion module types ## A. Polyphonic or quad envelopes / VCAs after Fractaos? Since Fractaos outputs stereo mix rather than per-voice audio outs, external VCAs won’t give per-voice control unless you’re controlling another downstream layer. Still useful for: - global tremolo - sidechain dynamics - voltage-controlled send effects - performance muting ### Good pairings: - Happy Nerding 3xVCA / 4x Stereo Mix - Intellijel Quad VCA - Xaoc Tallin - stereo VCAs and crossfaders ### Creative use: Put a stereo VCA after Fractaos and animate whole textures rhythmically with envelopes or an envelope follower from drums elsewhere in the patch. --- ## B. Character filters after the stereo output Fractaos already has internal fractal filters, but external filtering can radically reshape its digital edge. ### Try: - **Warm analog stereo filter** - Rossum Linnaeus - Bastl Ikarie - QPAS - Morgasmatron - Stereo Dipole - **Fixed filter bank / resonator** - Frap Tools Fumana - ADDAC fixed filter bank - Resonant EQs ### Why this works: Fractaos can generate very dense upper partials, resonant noise, and complex digital motion. Analog filtering after it can “frame” the complexity into musically controllable bands. **Patch idea:** Use a bright fractal like Mandelbrot or Dragon, moderate Texture, then into QPAS with slow stereo modulation. It turns the already animated tone into a wide moving spectral sculpture. --- ## C. Wavefolders and distortion Even though Fractaos is already harmonically rich, external nonlinearity can turn its cleaner geometric models into monstrous material. ### Great companions: - Instruō tanh[3] - Intellijel Bifold - Frap Tools Brenso folder section - Schlappi Interstellar Radio - Noise Engineering Ruina modules - Retro Mechanical Labs / Metasonix if you want brutal coloration ### Creative use: - Feed **smoother fractals** like Julia, Rössler, or Fibonacci into wavefolding - Keep internal Texture lower - Use external saturation for dynamics instead of internal density This gives more separation between “source complexity” and “post-harmonic aggression.” --- ## D. Granular / buffer / glitch processors Fractaos’ evolving output is perfect for capture-and-refracture modules. ### Strong pairings: - Make Noise Morphagene - Qu-Bit Nebulae - 1010 Bitbox / granular-capable samplers - Instruō Lubadh - Mutable Clouds descendants / Monsoon / Typhoon - Data Bender ### Why: The module already produces complex unstable shapes and quasi-organic motion. Granularizing that can create material that sounds much deeper than either module alone. **Patch idea:** Set Fractaos in Drone mode with microtonal Spread. Feed stereo out into Morphagene. Splice tiny fragments and modulate gene size and slide slowly. Result: alien choir / bowed-metal fog. --- ## E. Resonators and physical-model style processing Some Fractaos timbres are noisy or impulsive enough to be excellent excitation sources. ### Pair with: - Mutable Rings / clones - Intellijel Rainmaker - 4ms Spectral Multiband Resonator - feedback delay networks - Karplus-capable delays ### Creative use: Use drum fractals or Rule30/Collatz as exciters for resonators. Or send a narrow, transient-rich Fractaos patch into Rings in external input mode for hybrid “fractal acoustic instruments.” --- ## F. Sequential switches and preset-oriented performance modules Because Fractaos uses presets and clear state changes, it rewards structured performance systems. ### Good matches: - sequential switches - scene controllers - voltage-addressable CV routers - clocked switch matrices - macro controllers like: - Faderbanks - Planar 2 - Tetrapad/Tête - Pressure Points - 16n external controller via MIDI/CV ecosystem ### Creative result: You can treat Fractaos as the “main sound brain” and animate all CV destinations from one playable control surface. --- # Specific creative patch concepts ## 1. Fractal percussion lab Fractaos includes 5 drum fractals: Kick, Tom, Snare, HiHat, Cymbal. ### Combine with: - trigger sequencer - probability/skipping trigger processor - transient shaper / compressor - analog filter - distortion - reverb send ### Patch: - Use four trig inputs for independent drum hits - Route tuned CV into the 1V/oct inputs to shift tonal drums like Kick/Tom - Modulate Chaos lightly with random CV for hit variation - Morph drum curves with a geometric primitive for hybrid pitched percussion - Follow with compression and a transient processor if available ### Result: A **synthetic percussion section** with more life than static drum modules, especially if you sequence note pitch into Kick and Tom. --- ## 2. Polyphonic swarm strings Use one of the texture models like String or Ensemble. ### Combine with: - polyphonic MIDI keyboard or sequencer - slow aftertouch-capable controller - stereo chorus / ensemble - lush reverb ### Patch: - Use MIDI poly mode - Texture high, Morph at medium - Primitive as Koch, Fibonacci, or Julia for harmonic glue - Slow CV to Speed and Amount so internal modulation breathes - Play with aftertouch to animate “organic drift” ### Result: A **digital string ensemble / swarm pad** that can sit between wavetable and physical-model territory. --- ## 3. Chord-memory drone cathedral This takes advantage of Drone Spread chord zones. ### Combine with: - slow random CV - precision offset - stereo filter - shimmer reverb - feedback mixer ### Patch: - Drone mode ON - Pick a texture or geometric fractal with rich overtone content - Set Spread in upper zone for chord scanning - Modulate Spread very slowly through a tiny attenuated range so chord families morph - Add gentle modulation to Morph and Primitive Chaos - Send to long reverb and subtle feedback path ### Result: A **self-evolving harmonic installation patch**. --- ## 4. Fractal FM lead voice The manual describes a simplified FM mode: - Loop OFF - Trig OFF - Morph ON - Spread OFF - Chaos OFF Then Amount becomes bipolar around center. ### Combine with: - expressive keyboard - portamento source - LPG or external filter - delay ### Patch: - Use a geometric main fractal, not a texture or drum - Choose a primitive with contrasting contour: e.g. Rössler, Koch, Hilbert - Sweep Amount around center carefully - Modulate Pitch with a subtle vibrato source - Use external LPG or VCF for articulation ### Result: A very unusual **fractal FM monosynth lead**, less predictable than classic two-op FM. --- ## 5. Four-voice algorithmic counterpoint Since Fractaos accepts 4 pitch CVs and 4 trigs, you can treat it like 4 voices of independent composition. ### Combine with: - four channels of generative pitch - clock dividers - logic - quantizer - gate delay / burst ### Patch: - Generate four related melodic streams - Quantize them to a scale - Send each to one Fractaos voice - Use a common CV into Texture or Morph to unify the timbre - Slightly offset trigs for staggered attacks ### Result: A **fractal chorale machine** where separate note logic meets shared timbral evolution. --- ## 6. Hybrid digital-analog bass engine Fractaos can do strong bass tones, especially with: - Cantor - Rule30 - Logistic - Fibonacci - some lower-depth Mandelbrot settings ### Combine with: - analog lowpass filter - drive/saturation - envelope follower or sidechain compressor - sub-octave if desired ### Patch: - Use a geometric fractal with moderate Chaos - Keep Spread low - Use Morph for subtle animation - Run into a strong analog lowpass and saturator - Sequence mono or paraphonic bass intervals ### Result: Tight but alive basses with unusual overtone movement. --- ## 7. Microtonal harmony generator Drone mode includes: - Just intonation - 7-limit flavor - 19-TET slice - Bohlen-Pierce subset This is rare and very musically useful. ### Combine with: - drones - sine-rich external voices - resonators - spectral analyzers / tuners - long-form ambient effects ### Patch: Use Fractaos as the **harmonic reference bed**, then improvise other oscillators or acoustic instruments against it. The chord spread system gives you instant microtonal harmonic contexts. ### Result: An easy entry point into **microtonal modular composition** without needing a dedicated tuning ecosystem. --- ## 8. Fractaos as “exciter” into huge effects Because Fractaos can generate sharp attacks, noise-like textures, and complex formants, it is an ideal front-end for effects-heavy systems. ### Best with: - spring reverb - shimmer - spectral freeze - delay networks - convolution / resonant IR modules - granular freeze ### Patch: - Use Storm, Aliasing, Cluster, or drum models - Animate Chaos and Texture - Feed into a freeze/granular/delay module - Reinject a bit of the processed signal via external mixer feedback ### Result: Massive cinematic textures from a single source. --- # Modules that particularly make sense with Fractaos ## Sequencing / control - **OXI One** — amazing if you want polyphonic, multitimbral, MIDI + CV flexibility - **Squarp Hapax** — ideal for MULTI mode and separate channel control - **Pamela’s Pro Workout** — clocks, envelopes, LFOs, Euclidean gates for four trig inputs - **Mutable Marbles** or equivalent — beautiful semi-random pitch/gate for fractal timbres - **Planar 2** — hands-on Morph/Texture/Spread performance control - **Batumi** — four related LFOs for multiple CV targets - **Maths** — classic for slew, envelopes, attenuversion, weird modulation shaping ## Audio shaping - **QPAS** — great stereo animation after Fractaos - **Ikarie** — stereo character and panning movement - **Mimeophon** — particularly good with drone textures - **Morphagene** — turns Fractaos into a soundworld generator - **Data Bender** — complements the digital instability beautifully - **Fumana** — spectral sculpting of dense fractal output - **Desmodus Versio / Starlab** — lush space for drones and pads ## Utility support - attenuverters - offset generators - CV mixers - matrix mixers - stereo mixers - precision adders - slews / lag processors These are important because Fractaos has several high-impact CV inputs. Fine control matters more than raw modulation quantity. --- # Best CV strategies ## 1. Use attenuation aggressively Fractaos has many “macro” parameters where tiny movement matters. Especially for: - Spread - Chaos - Primitive Chaos - Texture - Morph A matrix mixer or attenuverter lets you find the sweet spot between subtle animation and total collapse. --- ## 2. Separate “structural” from “gestural” modulation Use: - **slow CV** for Texture, Chaos, Primitive Chaos - **performance/manual CV** for Morph and Spread - **rhythmic CV** for Amount and Speed This tends to produce more musical results than modulating everything at once. --- ## 3. Let Fractaos handle complexity, let external modules handle space Often the best patch is: - internal timbral complexity from Fractaos - external stereo field and ambience from other modules Instead of stacking more oscillators, give it: - filters - delays - reverbs - matrix-controlled modulation --- # Preset strategy ideas Because presets store: - 11 main pot values - 5 switch states - envelope parameters You can build performance sets around categories like: - **A:** percussive fractals - **B:** harmonic geometric tones - **C:** unstable chaotic leads - **D:** drone textures - **E:** multitimbral “kits” In MULTI mode, one killer approach is: - Voice 1: LIVE for hands-on tweaking - Voice 2–4: preset locked roles This gives you one “improvisation voice” while the others hold down structure. --- # Some especially promising fractal pairings ## For tonal melodic work - Fibonacci + Koch - Julia + Rössler - Sierpinski + Mandelbrot - Rössler + Hilbert ## For unstable experimental work - Lorenz + Hénon - Rule30 + Dragon - Logistic + Collatz ## For hybrid percussive-pitched work - Kick + Koch primitive - Snare + Cantor primitive - Tom + Fibonacci primitive - Cymbal + Hilbert primitive ## For drone/pad work - Cloud + Julia - String + Koch - Cluster + Rössler - Ensemble + Fibonacci --- # A few performance-minded patch recipes ## “Fractal Choir” - Drone mode - Ensemble or Cloud - Spread in Just Intonation or Major 7 - slow CV to Morph - aftertouch from MIDI keyboard - stereo reverb after output ## “Broken Digital Tabla” - Snare/Tom/Kick fractals - Euclidean trigger sequencing - random CV into Chaos - analog bandpass filter after output - delay send on selected hits ## “Evolving Glass Organ” - Koch or Mandelbrot main fractal - Julia primitive - slow looping primitive modulation - external resonant stereo filter - shimmer reverb ## “Alien FM Brass” - simplified FM mode - Fibonacci or Cantor main - Dragon or Rössler primitive - Amount above center - external VCA and LPG articulation ## “Microtonal Black Metal Pad” - Drone mode - BP subset or 19-TET slice Spread - high Texture - saturated stereo filter - huge reverb - slow random modulation into Chaos --- # Final take Fractaos seems most rewarding if you **don’t treat it like a conventional oscillator**. It’s better viewed as: - a **polyphonic fractal timbre engine** - a **drone harmony computer** - a **multitimbral digital ensemble** - a **hybrid percussion synthesizer** So the best companion modules are not necessarily more sound sources, but modules that provide: - elegant control - modulation scaling - sequencing structure - stereo processing - spectral framing - spatialization If you want, I can also turn this into: 1. a **“best companion modules by budget” list**, 2. a **small / medium / large rack integration plan**, or 3. **10 concrete patch sheets** with knob suggestions and signal flow diagrams. --- [Generated With Eurorack Processor](https://github.com/nstarke/eurorack-processor)
