# Kaona Instruments — Stereo Weaver - [Manual PDF](../../manuals/stereoweaver.pdf) --- [Manual PDF](attachment) # Kaona Stereoweaver — using it for melodic components Stereoweaver is **not a pitch or note generator**. It’s a **mono-to-stereo spatial processor**. So when thinking about “melodic components,” its role is: - making a mono melody feel wider, deeper, and more alive - adding motion to repeated note lines - turning simple sequences into evolving stereo phrases - creating contrast between lead, bass, arp, and drone parts ## What the module does From the manual, Stereoweaver takes: - **1 mono input** - and creates **2 stereo outputs: L and R** Core controls: - **Depth** — controls perceived depth and effect interaction - **Phase** — shifts phase relationship between channels from 0–180° - **Motion** — controls animation speed; includes **Rotary** mode - **Haas** — adds inter-channel micro-delay for spatial spread - **Width** — widens stereo image; includes **Move** behavior - CV inputs for: - Depth - Phase - Haas - Width Other important details: - **Input gain** with clip indication - **Independent L/R output levels** - CV inputs are **bipolar ±5V** - CV amount is influenced by the corresponding knob position --- # Best use in a melodic Eurorack patch ## 1. Stereo lead voice enhancement Patch a complete mono melodic voice into Stereoweaver: - VCO → VCF → VCA/envelope - voice output → **Stereoweaver IN MONO** - **OUT L / OUT R** → mixer or output module Use settings like: - **Depth:** low to medium - **Phase:** low to medium - **Motion:** slow - **Haas:** moderate - **Width:** medium Result: - lead stays centered enough to remain intelligible - stereo field opens around it - repeated notes feel less static - small differences in phase and Haas give presence without sounding like delay This is ideal for: - melodies - arpeggios - plucked lines - acid-style leads that need space without reverb --- ## 2. Make a simple sequence feel expressive A basic 8-step melody can feel mechanical. Stereoweaver helps by adding **micro-movement**. Patch: - sequencer → oscillator pitch - gate → envelope - mono synth voice → Stereoweaver - slow LFO → **Phase CV** - another slow or unsynced LFO → **Haas CV** or **Width CV** Why this works: - the notes themselves do not change - but the *space around each note* evolves - this creates the perception of phrasing and development This is especially good for: - repeating ostinatos - Berlin-school sequences - techno arps - generative melodic loops --- ## 3. Animated stereo arpeggios Arps benefit a lot from spatial differentiation because the note content is already active. Suggested patch: - arpeggiated mono voice → Stereoweaver - clocked triangle or sine LFO → **Width CV** - slower LFO → **Phase CV** - set **Motion** between slow and medium Try: - **Depth:** medium-high - **Phase:** medium - **Haas:** low-medium - **Width:** medium-high Result: - different notes seem to occupy slightly different places in stereo - the arp becomes less “flat” - it feels like one melodic line unfolding in space If you push Depth and Phase, you can get: - micro-chorus - slight phasing - a glassy or dreamlike animated arp texture --- ## 4. Leslie-like melodic motion with Rotary mode The manual notes that **Motion** has a **Rotary** region that simulates a Leslie-type effect with: - separate low/high “speaker” behavior - speed offset - amplitude variation - phase variation This is very musical on: - sustained leads - organ-like patches - drones with melodic articulation - legato mono lines Patch idea: - saw or pulse voice with gentle filter movement - into Stereoweaver - set **Motion** to **Rotary** - modulate **Phase CV** slowly - keep **Haas** moderate This can make a static melody feel: - spinning - breathing - vintage - harmonically richer due to phase interaction For melodic use, avoid maxing everything at once unless you want abstraction. --- ## 5. Make counterpoint from one melodic line Even though Stereoweaver doesn’t create new notes, it can make one melody behave like **multiple spatially interacting strands**. Use: - **Width** up - **Move** behavior engaged - **Motion** controlling displacement speed - **Phase** raised enough to increase channel differentiation The manual says in Move mode: - left and right channels progressively exchange levels - speed is defined by Motion - amplitude depends on Phase - at maximum, displacement becomes more chaotic Musically, that means a single line can feel like: - it is being answered from side to side - notes are “thrown” across the stereo field - a melodic figure has internal motion similar to call-and-response Great for: - FM plucks - percussive melodies - minimalist repeating motifs --- ## 6. Bassline support with careful stereo widening Bass melodies can be widened, but carefully. Recommended: - **Depth:** low - **Phase:** low - **Haas:** very low - **Width:** subtle - **Motion:** slow This preserves: - punch - center stability - mono compatibility Useful when: - the bassline has upper harmonics - you want subtle spatial animation without smearing the low end A good trick is to feed Stereoweaver a bass voice with some filtered harmonics or wavefolding, so the spatial effect is heard more in the upper partials. --- ## 7. Turn drones into melodic beds A drone or held note can become a melodic support layer if its spatial structure evolves. Patch: - sustained oscillator or chord-like mono sum - slow envelope or random voltage to timbre/filter - into Stereoweaver - random stepped CV or smooth chaos → **Width CV** - slow sine → **Haas CV** - slow offset LFO → **Phase CV** This creates: - a stereo bed that shifts over time - a background layer that supports foreground melodies - the illusion of melodic movement even when pitch is static Especially effective in ambient and soundtrack work. --- # How each parameter affects melodic material ## Depth This is the “immersion” control. - **Low:** direct, forward, focused - **High:** deeper, more enveloping - **Very high:** can produce micro-chorus and micro-phasing For melody: - use **low-medium** for intelligible leads - use **medium-high** for dreamy arps and pads - use **high** for experimental melodic textures ## Phase This defines much of the stereo character. It affects: - coherence - strangeness - diffusion - stability For melody: - lower values keep lines more solid - higher values can make notes shimmer or sound uncanny - CV on Phase is excellent for long-form evolution ## Motion This determines animation speed and can enter Rotary mode. For melody: - slow = natural movement - medium = noticeable stereo animation - rotary = expressive sustained lead treatment If Width is in **Move mode**, Motion sets displacement speed. ## Haas Adds micro-delay between channels. For melody: - moderate settings add presence and natural width - higher settings make it more dramatic and characterful Useful for making a mono voice sound immediately larger without obvious echo. ## Width Controls stereo spread and center hollowness. For melody: - subtle width keeps focus - higher width makes a line cinematic - Move mode adds dynamic left/right exchange This is one of the strongest controls for making repeated notes feel active. --- # CV strategies for musical patches Since the CV inputs are bipolar and summed with knob settings, modulation can be very expressive. ## Good modulation sources Use: - sine LFOs for smooth stereo drift - random smooth voltage for organic variation - envelopes for note-dependent widening - stepped random for more experimental placement - sequencer CV for phrase-based spatial changes ## Especially useful assignments ### Width CV from envelope Each note opens wider at attack, then narrows. Effect: - melodies “bloom” on each note ### Haas CV from slow LFO Stereo depth breathes over bars. Effect: - long phrases feel alive ### Phase CV from random smooth source Creates subtle instability and uniqueness. Effect: - repeated melodic loops avoid sounding identical ### Width CV + Motion in Move mode Creates side-to-side phrase travel. Effect: - spatial rhythm emerges from a static sequence --- # Example melodic patch recipes ## Patch 1: Wide techno sequence - 8-step sequencer → VCO - gate → envelope → VCA - saw voice → lowpass filter - filter/VCA output → Stereoweaver Settings: - Depth: 11 o’clock - Phase: 10 o’clock - Motion: 9–10 o’clock - Haas: 11 o’clock - Width: 1 o’clock Modulation: - slow LFO → Width CV - slower LFO → Haas CV Result: - wide, stable, modern stereo sequence --- ## Patch 2: Dreamy ambient lead - triangle/sine + subtle FM - long envelope - mono voice → Stereoweaver Settings: - Depth: 2 o’clock - Phase: 1 o’clock - Motion: slow - Haas: noon - Width: 2 o’clock Modulation: - smooth random → Phase CV - slow sine → Width CV Result: - floating melodic line with evolving stereo aura --- ## Patch 3: Rotating organ melody - organ-like patch or additive voice - mono output → Stereoweaver Settings: - Depth: medium - Phase: medium - Motion: Rotary - Haas: low-medium - Width: medium Modulation: - slow CV to Phase - optional envelope to Width Result: - animated rotary-style melodic performance --- ## Patch 4: Nervous experimental plucks - short-decay pluck voice - mono output → Stereoweaver Settings: - Depth: high - Phase: medium-high - Motion: medium-fast - Haas: medium - Width: high / Move region Modulation: - stepped random → Width CV - smooth random → Haas CV Result: - melody turns into spatially fragmented, glitchy motion --- # Practical performance advice ## Keep the center for important melodies If the melody must remain clear in a mix, do not overuse: - Phase - Haas - Width A little goes a long way. ## Use stronger settings on secondary melodies Countermelodies, echoes, and background arps can tolerate: - more Depth - more Width - more motion - more phase weirdness ## Watch mono compatibility Because phase and Haas processing affect inter-channel relationships, extreme settings may collapse oddly in mono. So for club-focused or mono-sensitive music: - keep bass nearly centered - test the lead in mono - use the wildest settings on upper textures ## Use clipping musically The manual notes the input can be driven intentionally. That means you can feed a hot melodic voice for extra coloration and interaction with the spatial effect. This can be great for: - aggressive leads - acid lines - distorted drones --- # Bottom line Stereoweaver is best thought of as a **melodic space animator** rather than a melody generator. It helps create melodic components by: - widening mono leads into stereo - adding movement to repetitive sequences - making arps and plucks feel more dimensional - creating rotary and phasing-like character for sustained notes - turning static phrases into evolving stereo performances If you pair it with: - a sequencer - one mono synth voice - a few LFOs or random CV sources you can get a lot of melodic richness from otherwise simple material.
