ZS KGMTP
Frequency Multiple & Spectral Reconstruction Instrument
KGMTP is a frequency-multiplication and spectral leveling instrument designed to take extremely low-level, fragmented, or sparse signals and expand them into dense, audible, controllable sound structures.
Rather than generating sound traditionally, KGMTP amplifies, multiplies, and reorganizes existing frequency energy.
Core Concept
Multiplication Instead of Generation
KGMTP is built around the idea that one frequency can become many.
Instead of adding oscillators or voices in the usual way, the synth:
- Takes incoming or internal frequency content
- Duplicates it across multiple internal paths
- Offsets each copy slightly in time, phase, or frequency
- Recombines them into a single output
This allows tiny signals, quiet tones, or simple inputs to become large, complex, playable sounds.
The Multiple Function
Frequency Duplication Engine
The Multiple is the heart of KGMTP.
It:
- Duplicates frequency content across multiple internal paths
- Offsets each copy slightly in time, phase, or frequency
- Recombines them into a single output
This is not chorus, not unison, and not detune.
Instead:
- Each multiple behaves as a real frequency instance
- Interaction between multiples creates new partials
- Density increases without simple loudness increase
The result is:
- Thick, structural sound
- Harmonic and inharmonic growth
- A feeling of expansion rather than layering
“Bring Everything Up to Level” Effect
Spectral Energy Recovery
KGMTP includes a unique level-recovery system designed to lift all frequency components — even extremely quiet ones — into the audible range.
This system:
- Detects very low-level spectral energy
- Raises it proportionally, not uniformly
- Preserves internal balance between frequencies
- Avoids traditional compression artifacts
What this means musically:
- Subtle details become audible
- Quiet harmonics are revealed
- Extremely low-level sounds become usable material
- No single frequency dominates unless you push it
Color Box
Spectral Character Control
The Color Box shapes how multiplied frequencies behave.
Rather than acting as an EQ, it:
- Adjusts harmonic weighting
- Alters spectral emphasis
- Changes how frequencies interact after multiplication
Color affects:
- Brightness vs darkness
- Smoothness vs grit
- Metallic vs organic tone
- Perceived depth and density
Because Color is applied after multiplication, small changes can dramatically reshape the sound.
Inverse Gate
Negative Space as a Sound Tool
The Inverse Gate works opposite to a traditional noise gate.
Instead of letting loud signals through and cutting quiet ones, it:
- Suppresses dominant energy
- Reveals quieter or hidden components
- Opens space inside dense sound
This allows:
- Hollow, spectral textures
- Moving negative space
- Rhythmic absence instead of presence
- Controlled instability
The Inverse Gate is especially effective when paired with the level-recovery system, creating sounds that feel inside-out.
Voices
True Structural Voices, Not Simple Polyphony
Voices in KGMTP are structural duplicates, not lightweight polyphonic voices.
Each voice:
- Has its own multiplied frequency structure
- Interacts with other voices
- Can interfere, reinforce, or cancel harmonics
This allows:
- Massive stacked sounds without simple loudness gain
- Complex beating and motion
- Dense unison-like behavior without classic detune artifacts
Voices increase interaction, not just count.
Interaction Between Systems
The power of KGMTP comes from how these features work together:
- Multiple creates density
- Level Recovery makes everything audible
- Color Box shapes the spectrum
- Inverse Gate carves negative space
- Voices multiply interaction
Together, they turn simple input into rich, evolving, high-detail sound.
Intended Use
KGMTP is ideal for:
- Turning simple tones into massive textures
- Revealing hidden harmonics
- Creating dense drones and evolving pads
- Designing abstract, experimental sounds
- Generating material for rendering and resampling
It excels when:
- You push it hard
- You render instead of playing live
- You treat it as a sound construction tool
In One Sentence
KGMTP takes small amounts of frequency energy and multiplies them into dense, controllable sound structures that traditional synths cannot produce.
ZS_DRSYN_X_
1. Core Concept
This instrument is not a traditional oscillator → filter → amp synth.
Its core function is to construct audible sound by mathematically folding and heterodyning infrasound and ultrasound around a 1 Hz reference, then collapsing that energy into the audible band through controlled non-linear interactions.
Instead of “generating notes,” it creates interference structures that become notes.
2. Engine Architecture (8 Engines)
The synth contains 8 fully independent engines, each one being a complete signal-generation system.
Each engine consists of:
A. 1 Hz Carrier (Foundation)
- Every engine starts from a 1 Hz carrier
- This carrier is phase-accurate and continuous
- All higher frequencies are derived as ratios, folds, or heterodynes of this base
This guarantees:
- Perfect long-term phase coherence
- Predictable beat structures
- Stable sub-audible modulation behavior
B. Infrasound Bank (8 Oscillators)
- Frequencies below 20 Hz
- Used not as audible sound, but as structural modulators
- These drive:
- Phase bending
- Time-domain folding
- Envelope distortion
- Sub-harmonic beating
Infrasound never “plays” — it shapes.
C. Ultrasonic Bank (8 Oscillators)
- Frequencies far above Nyquist
- Intentionally aliased by design
- When folded back into the audible domain they generate:
- Metallic sidebands
- Dense harmonic clusters
- Inharmonic spectral smear
Ultrasound acts as spectral fuel.
3. Heterodyne Beating & Folding
The audible output is produced through heterodyne math:
f_out = |f1 − f2|
Where:
- f1 may be infrasonic or ultrasonic
- f2 may be audible or sub-audible
This causes:
- Beat frequencies to appear in the audible range
- Pitch to emerge from difference tones
- Motion without traditional LFOs
Folding Stages
Signals are repeatedly:
- Reflected
- Wrapped
- Absolute-valued
- Clipped symmetrically
This produces:
- Nonlinear harmonic generation
- Fractal-like spectral repetition
- Perceptual “pressure” rather than loudness
4. Color Box (96 Harmonic System)
Each engine includes a Color Box containing 96 harmonic paths.
These harmonics include:
- Standard harmonic ratios
- Subharmonics
- Negative harmonics (phase-inverted ratios)
- Extended regions labeled infrared (below fundamental) and ultraviolet (above harmonic series)
Polarity Modes
Each harmonic can be:
- Positive
- Negative (inverted phase)
- Offset asymmetrically
This allows constructive and destructive interference instead of filtering.
5. LFO System with Peak-Width FM
The LFO is not a simple periodic modulator.
It uses:
- Peak-width modulation instead of duty cycle
- FM applied to the shape itself, not the output
- Variable curvature rather than linear ramps
Mathematically:
- LFO = function(time, curvature, phase skew)
- FM affects zero crossings, not amplitude
This prevents:
- Static motion
- Predictable looping artifacts
6. Math Engine (diff / abs / sum / random)
The synth continuously recombines signals using:
- Difference (heterodyne)
- Absolute value (folding)
- Summation (energy accumulation)
- Randomized coefficient perturbation
These operations are:
- Sample-accurate
- Often recalculated per block
- CPU-heavy by design
Random terms are:
- Bounded
- Correlated (not white noise)
- Used to avoid limit cycles and tonal freezing
7. Random Cycle Detune
Unlike traditional detune:
- Each oscillator’s cycle length is slightly randomized
- Randomization happens per cycle, not per note
- Drift is micro-temporal, not pitch-based
Result:
- No chorusing
- No beating in the classic sense
- Living, unstable spectra that never lock
8. Modulation Matrix
The matrix is bipolar and bidirectional.
Key traits:
- Sources and destinations can modulate each other
- Modulation depth can exceed unity
- Negative modulation inverts causality
This allows:
- Feedback modulation paths
- Cross-engine spectral mutation
- Chaos-adjacent behavior without instability
9. Global FX System
Global FX are post-engine but pre-normalization.
They are:
- True multi-input / multi-output
- Designed to preserve phase relationships
- Intended to enhance density, not coloration
They operate on energy structures, not “sound.”
10. Resynthesis System (270 → 1 Oscillator)
The resynthesis engine:
- Analyzes spectral energy
- Reconstructs it using up to 270 internal oscillators
- Then collapses them into a single coherent oscillator
This produces:
- Massive harmonic density
- Phase-locked reconstruction
- Extreme efficiency after collapse
It is spectral compression, not additive synthesis.
11. Smart Gain Normalization
Smart Gain is not a limiter.
It:
- Measures RMS and spectral density
- Accounts for folded ultrasonic energy
- Normalizes perceived loudness, not peak level
It ensures:
- Consistent output regardless of complexity
- No pumping
- No transient destruction
12. Summary (What This Synth Actually Is)
This synth is:
- A frequency-interference generator
- A heterodyne-based spectral constructor
- A folding engine using infra and ultra sound
- A nonlinear resynthesis instrument
- A controlled chaos system with phase integrity
It does not:
- Rely on filters
- Use traditional subtractive flow
- Generate sound in a linear manner
It creates sound by forcing frequencies to collide until structure emerges.
13. Multi-Channel High-Pass / Low-Pass System (8 Channels, 15 Routing Modes)
In addition to its folding and heterodyne architecture, the synth contains 8 dedicated filter channels, each capable of operating as high-pass or low-pass.
These are not conventional tone-shaping filters. They function as structural separators and routing gates inside the interference network.
Channel Structure
- 8 independent HP/LP channels
- Each channel can be:
- High-pass
- Low-pass
- Dynamically switched or modulated
- Filters operate per engine or across engines, depending on routing mode
